Kind: captions Language: en today we're going to talk about daily habits that can boost brain health and prevent Decline and by decline I'm talking about cognitive decline so here's a thing that I think you should be doing every single day number one start your day with a cup or two or three of coffee now coffee is one of the oldest beverages in the world it's um one of the top three after drinking water and tea uh and here's thing about coffeee is that uh it's not just a morning ritual it actually contains bioactives that is good for your brain for brain health some of the bioactives include chlorogenic acid chlorogenic acid reduces inflammation in the brain very important inflammation on the whole body but also in the brain the chlorogenic acid that you drink with a cup of joe actually crosses the blood brain barrier now now the brain is kept in the skull and there's a filter that keeps out all the bad stuff it's called The Blood brain barrier it's made out of the lining uh blood vessels and so when blood tries to go through that lining it's actually filtering out any of the harm things chlorogenic acid goes right through it into the brain lowering inflammation the other thing that's in coffee is caffeine right so uh we know that caffeine which has another name is called a methyl xanthine all right also known AKA as caffeine Caff uh gets into the brain goes through the bloodb brain barrier and it actually does some really really interesting things it improves your cognition improves your memory it increases your ability to uh focus and concentrate I know when I was in medical school I actually drank a lot of coffee so that I could actually get up after a late night of studying or a late night of being on call if I had to actually be like up and uh alert the next day coffee would always help I think most people uh know that if you're a truck driver and you're drinking a cup of coffee you know going that 18-wheeler down across the country same deal okay so that's uh caffeine and then there also cafeic acid which is another bioactive that actually is anti-inflammatory um and protects your neurons which your brain is made out of neurons okay so let me just tell you this benefit of coffee has been uh supported by clinical studies in fact clinical Studies have shown that drinking anywhere between two to five cups of coffee a day are right can increase alertness increase your increase your attention span improve your sense of well-being and uh sharpen your concentration that's what you want right now people have a lot of beef against the caffeine and coffee and some people are really sensitive to it but actually for most people if you can actually tolerate the caffeine uh this is actually a big cognitive brain health benefit of drinking coffee now other Studies have shown that if you're a lifelong Drinker of coffee that would be me uh I'm sure some of you also are lifelong or many year decade long drinkers of coffee that's actually where the benefits are shown in terms of lowering the risk of cognitive decline and dementia pretty amazing benefit from drinking something that you know sort of uh instinctual instinctive of drinking every single morning now caffeine uh in coffee improves brain neuron function your brain is made out of neurons these are nerves that have to communicate from one neuron one nerve cell to the next okay think about a little zap of electricity getting this way this one zaps over there that's how the brain actually works and caffeine improves that function and it actually Pro protects the neurons in your brain against dysfunction meaning problems with the wiring so the electricity the current isn't flowing well uh caffeine protects it to keep that electrical current that neuro transmission uh very very smooth in your brain studies have also shown that drinking coffee reduces the risk of stroke reduces the risk of Parkinson's disease and reduces the risk of Alzheimer's disease most of these are Association studies done in large populations but hey we know that the coffee actually protects the neuron the cafeic acid chlorogenic acid lowers inflammation so that large epidemiological studies showing this correlation make perfect sense all right now uh caffeine is has also uh been implicated specifically uh in being able to protect against Alzheimer's disease which is really good this is a lab research looking at what caffeine actually does to the plaques that um Alzheimer's model uh form these are usually mice they look at the effect of caffeine they also take a look at chlorogenic acid in a lab to see what it does to the circulation of your brain now let me explain if you want good brain health you need to have good vascular health or good blood vessel Health you know why because there are 400 miles of blood vessels in your brain and these are the highways and byways that are bringing oxygen to your brain cells nutrients to your brain cells glucose to your brain cells that's right I said glucose some of you might say well you know isn't glucose bad nope your brain absolutely needs glucose in order to function in fact you would have brain fog if you actually didn't have enough blood sugar healthy amounts of blood sugar uh in your brain now so how do you get um good vascular Health again these are the highways and byways of everything oxygen and nutrients and survival factors to your brain well you need to actually have good endothelium that's the lining of the blood vessels has to be really healthy the lining of the blood vessels is like an ice skating rink the ice is really smooth you know if you go to the ice skating rink if you ever skated when you were a kid after the Zamboni that's the polishing the ice Pol polishing machine runs through it man is that ice slippery and smooth perfect for skating right in fact if you took a sweater and you threw it after the Zamboni that's a machine that cleans the ice you threw the sweater out it would slide all the way across the ring right now that's what you want but the endothelium the lining of the blood vessels have to be smooth but when you get older in particularly if you've got a hard ring of the arteries high cholesterol diabetes or smoking cigarettes exposed the secondhand smoke um have all kinds of other chronic diseases inflammatory diseases the endothelial lining including the lining in your brain those 400 miles gets damaged when the endothelium that lining of blood vessels that slippery lining gets damaged you know what happens it is like an ice skating rink after a hockey game right think about how roughed up that ice is right so if you've ever been to a regular public ice skating rank when you were a kid after a session of skating if you took that sweater and threw it on the ice would happen it would just stay right there there's no way it would slide because ice is so roughed up that's what can happen with endothelial damage damage to the lining of the blood vessels and when that actually happens your brain is not getting good blood flow and the sticky lining can actually start to attract lipids so then your blood vessels get even more narrow and of course when you've got stickiness guess what your blood platelets can stick and that can cause micr clots and that can cause vascular dementia so if you want good brain health you want good vascular Health if you want good vascular Health well chlorogenic acid which is found in coffee actually protects it keeps the ice um the the ice skating rink slippery and smooth the way that you want it so blood can flow smoothly right through the 400 miles of blood vessels in your brain really really important that is key to preventing vascular dementia which is a very very common form of dementia where you don't have good blood vessels good blood flow uh to your brain and you without adequate oxygen to your brain you know it's not quite having a heart attack to your brain but it's not getting enough oxygen it's kind of like a a scuba diver that's sucking on a tank that's almost out of air it is a dangerous situation you can't function uh very well in that kind of scenario okay now here's another kind of benefit uh for coffee and that is that coffee benefits gut health coffee benefits gut health it's beneficial to the gut microbiome that's a healthy gut bacteria and guess what because coffee actually gets all the way down to your gut microbiome and this is another benefit is that it's been shown to reduce the risk of the development of colon cancer right you drink your coffee good stuff to the brain all right this is what we're talking about with this video but it also tumbles all the way down to your gut good for your gut microbiome lowers the risk of coloral cancer that's what clinical studies have found oh but wait a minute gut health is is good for brain health right that's the gut brain axis we're talking about and so when you drink coffee that's good for gut health it actually benefits your brain as well it improves uh the ability for the brain's neurotransmitters to be able to form like dopamine serotonin oxytocin these are the things that our gut bacteria communicate help our brain communicate to release these neurotransmitters okay now I can tell you this a little bit more in in terms of neurotransmitters is important to think about studies in the lab have shown that the caffeine the kind of caffeine found in coffee can reduce stressinduced neurotransmitter responses all right so when you're super stressed out your brain is releasing neurotransmitters like crazy it's like a lightning storm going off in your head because of stress right you know like when you're feeling panicked and super stressed out your brain is kind of nuts right and this is what's happening neurotransmitter are firing left and right um think about it like six shooters shooting left and right everywhere all right well what caffeine does is it reduces that neurotransmitter chaos all right and what this does is actually help Focus attention your brain's ability to focus attention under stressful circumstances I can tell you as Somebody went to medical school and medical training residency training this is the kind of stuff that even though we were drinking coffee all the time when we you know just kind of stay awake whenever we actually had a uh stressful super stressful clinical situation code blue right this is a cardiac arrest like we're all running uh into the area to the hospital room where the cardiac arrest took place boom we were absolutely laser focused like Navy Seals on taking care of that patient and making sure all the things that were done were being done completely in a focused Accurate Way all right so this is I'm just telling from my own experience how coffee drinking actually made it easier for me to stay really really focused under condition of stress now there was a rumor a long time ago that came up to said well you know don't drink too much coffee because it actually will make your heart rhythms go crazy it can cause atrial fibrillation it can cause all these other problems well actually it's been shown now that drinking coffee reasonable amounts of coffee so I'm talking about two to five cups a day does not increase the risk of heart disease does not increase the risk of arhythmia does not okay so safe now if you actually have atal fibrillation and you are sensitive to caffeine this is something you should actually talk to your cardiologist about I can't give you medical advice on a video like this but if you already have an arhythmia uh and you're and you're trying to drink coffee you might want to actually have a conversation with your cardiologist just to be safe that's what I recommend people to do but if you don't have it uh drinking coffee doesn't doesn't cause it all right that's the key thing like I said some people are sensitive to caffeine uh and it could it you know and and every individuals different this is personalized reactions to different kinds of foods um and uh caffeine uh can sometimes cause sleep disturbances it doesn't happen to everybody that's actually what the generalization is oh I'm not going to drink coffee at night because it's going to disturb my sleep actually doesn't disturb sleep for everyone like for me I could drink a cup of coffee uh in the evening and it wouldn't disturb me at all and in fact if you look at how people in the Mediterranean actually work uh like in Italy they will eat an Italian meal dinner and often times they'll have one small cup of espresso after dinner Boop Shove It Right Down the Hatch and um and it doesn't actually disturb sleep at all in fact what it does is it actually decreases sleep latency so the next morning it's a little easier to get up in the morning that's a whole other topic that that we're going to address in another video this whole idea of sleep latency now some people do are sensitive to coffee and it could make them more an but again this whole idea about like caffeine triggering heart rhythm you know problems and causing insomnia and triggering anxiety that may be true on an individual basis but it can't be generalized and the overall benefits of drinking coffee are exceedingly uh good but you should actually take a look at your individual tolerance to coffee now some people also do experience caffeine withdraw if they stop coffee all of a sudden I don't know why you'd want to do that um I love my coffee uh I guess if I run out of coffee beans or run out of ground coffee I might not drink it a day or two but for the most part if you stop coffee for a couple of days you're probably going to be just fine in fact a great example is if you go on vacation if you're you know working and drinking coffee you do a regular day job you go on vacation and you're like ah I get to kick my heels up and relax a little bit if you don't have that cup of coffee you're probably going to be just fine so it's context dependent all right so that was tip number one tip number two uh for brain health is I I said to start your coffee with coffee and now I'm going to tell you to end your day with a cup of tea we're talking about daytime habits that's you for brain health start with coffee end with tea this is what I actually do almost every single night now why do I end with tea well tea is good green tea we know as kakin egcg epic Gallow kakin 3 gal all right it's a mouthful uh you don't have to try to memorize it just know that researchers like me actually we know what it is all right so polyphenols green tea green tea also has caffeine right and it also has something called lanine guess what all of these uh bioactives egcg caffeine Aline they are all anti-inflammatory end of the day what better thing can you do than to cool off any inflammation right so that's what green tea does um by the way lenine has been studied it actually improves calmness as well so clinical trials have been done in humans uh uh being administered eleine and it it actually induces a sense of calmness and a sense of relaxation calms your mind so that's one of the reasons why I drink tea at the end of the day after dinner you know I might sip some tea I never put dairy in my tea or coffee by the way because um dairy cow uh fat actually forms little tiny soap bubbles around the polyphenols and when I drink the coffee or the tea I'll still get some of the bioactives but a lot of it gets wrapped up in those little soap bubbles from dairy uh milk dairy fat and then it tumbles down through my gut and I don't absorb as much as I could now nut milks are okay so if you really want to cut your tea or coffee you know an almond milk or soy milk or cashew milk all that is actually fine they won't form those same type of soap bubbles all right back to tea um if I want to get as much egcg as I can I'm drinking my tea straight I'm sipping it at the end of the day it's calming uh and uh the other thing it does is it actually improves a process called neurogenesis so this has been studied in the lab that the bioactives like egcg from tea can actually help your neurons stay healthy and they can even cause them to grow this has been studied in uh sort of developing uh animals young anim anim and looking at brain development guess what it helps your nerves actually grow now some tees like Macho which is packed with egcg right so look regular tea leaves that you're actually soaking and steeping in a tea ball for example is uh dissolving out the the polyphenols in hot water you're steeping the tea all right um and a lot of the polyphenols will come out but not all of it cuz it's a whole Leaf well matcha actually is the entire Leaf ground up into a fine powder now you've got this fine powder all of it is actually in the water you stir up a cup of matchats powdery green bright green you're going to get all the tea leaves all the dietary fiber good for your microbiome but all the polyphenols all the egcg all the Aline uh all the caffeine as well so matcha te has been studied clinically and shown that not only is in high levels of egcg has high levels of egcg bioactives it's also been shown to enhance cognitive function right so here's an advantage of grounding up the whole Leaf as opposed to just seeping the tea leaves or putting in a tea bag where you're not going to get all those polyphenols out that you could all right clinical studies have also shown that green tea can reduce anxiety again that calming effect of eleine um and calming anxiety is actually really important for self-care really important for mental health and mental wellness and look who doesn't live with some amount of stress in fact arguably some stress is good for your health you don't want to be completely chill the whole time a little tension is good in your life but unfortunately in our usual lives we uh live with probably too much stress so it's a welcome opportunity to have a cup of tea at night to actually lower your stress now the um other thing is that elen has been studied and it improves clinically it improves the ability for executive function decisionmaking right now you don't need you might not need this at night but you you certainly want it the next morning when you wake up so heeing actually helps your brain we're talking about brain health now be able to make clearer calmer better executive decisions you don't want to be the CEO you're the CE of a company you can be the CEO of your own life and you want to be able to be that executive and make good executive decisions for yourself it doesn't matter even if if it affects anyone else even if it's just for you you want to make have Clarity on that and lth in green tea is actually good now green tea also improves memory and the ability to stay focused uh so you have less distractions again this is not something you need at night uh you want calmness at night but actually having all this stuff in your uh bloodstream allows you to function better the next day you wake up and your brain is refreshed it had a calm night of sleep and now you've got this ability to focus and make better decisions that's actually a really really good thing and how do we know that green tea can affect brain uh activity the kind of brain activity we're talking about because there is actually a scan called fmri functional MRI magnetic resonance imaging that actually been shown and people have to drink tea you stady brain activity and you can see it light up it actually does uh your brain a world of Good by lighting it up the ecgc we talked about reduces the risk of cognitive decline it protects you against neurod degenerative diseases there's multiple mechanism of action we don't understand everything about how this works look I'm a scientist and an honest scientist will tell you when they don't know so I'm telling you we don't have all the answers to how green tea and the egcg protects against neurod degeneration but clearly one of the reasons one of the explanations that it lowers inflammation that's one of the common denominators of all brain diseases is inflammation so green egcg lowers that inflammation all right now the other thing that EG CG and the other polyphenols and green tea does is it improves your endothelial health remember the endothelium is that ice skating slippery layer of cells lining blood vessels you want it to be really smooth blood just kind of goes like it just cruises right through your brain delivers the oxygen delivers the nutrients green tea helps vascular Health reduces the risk of vascular dementia helps that blood get to where it needs to in your brain so you actually have better function all right so drink coffee uh in the morning drink tea at night now the third thing a habit I'm I'm telling you that's good for your brain health is to pay attention to how you can improve your metabolism throughout the day now metabolism is basically how your body uses energy which you have to get that fuel for your energy by eating food right so you eat food it gets turned into fuel the fuel gets stored in your body and then your body can actually run its activities you know run it basic functions but you can also run to the airport or do whatever else you need to do um because you have the fuel like gas in a gas tank that's how your metabolism actually works and how many calories you eat is exactly equivalent in terms of concept into how many gallons of fuel you actually put in your fuel tank now obviously if you want to put fuel in your fuel tank you want to put good quality fuel nobody wants to put crappy fuel in your fuel tank and this is the same with the quality of food that you load energy into your body you want good quality fuel means you have to eat good quality food so when we talk about having um uh good Whole Foods mostly plant-based eating and healthy oils nuts and legumes and and seeds etc etc this is what we're talking about we're talking about good quality fuel now just like a car every now and then if you put some crummy gas because you're running out of dollars you're searching for the small change that you could put a couple of gallons in your tank look do that once in a while your car is not going to crap out because of that but if you put crappy quality fuel fuel in your body day in and day out week after week month after month year in and year out you know what's going to happen to your car when you put poor quality fuel all the time into your car it's not going to last long that engine is not going to function as well the fuel lines are going to get clogged same deal in your body so to take care of your your metabolism and by the way I'm talking about brain metabolism being super intense compared to your regular body metabolism you want to actually put good quality fuel in your tank and you don't want to actually put too much uh in your tank as well if you overflow your gas tank what happens in like at the gas station if you overflow your gas tank that's like eating too much oving too many calories in your body well at The Filling Station if you put too much gas in your gas tank the gas flows up if you didn't have that clicker that would stop the the the gas nozzle what would happen the gas would overflow out of your tank run down the side of the car around the tires cool around your shoes and now you're standing in a dangerous harmful flammable mess right that's what happens when you overflow overfill your gas tank now imagine if you did that uh with food and this is what happens we overeat overc consumption is one of the underlying problems in Western Society including America we overeat uh you know it's a it's a product of having a prosperous Society we've got food everywhere there's no limitations we eat as much as we want well sometimes we want too much or we overeat we addicted to eating or we're uh conditioned uh or even fooled into eating food uh that tastes really great Ultra processed foods when we overeat we are overloading our fuel tanks and that is bad because it overloads our metabolism we're storing too much fuel now in our body we don't we can't just uh spill out the fuel like in a like a metal gas tank in a car what happens is that our extra fuel gets stored into our fat cells also called atpo cells you fill up one atpo cell with too much food that's okay you got another atpo cell oh you're still eating let's fill that one up too oh still eating you fill up another one until you're running out of fat cells now your body if you still keep on overeating will call in stem cells fat stem cells to make more fat now you can make more FL fill up another Fat cell and another one and another one and you see this is why when you overeat you're actually going to build up fat all right this is actually how it works our metabolism then our body's got to burn it down but our body isn't going to be able to burn things down naturally if we overload it over a long period of time and this is why we have to control the amount of food that we eat okay so um you got to watch your metabolism not overfill your tank now habit number four is you want to eat food foods that activate your metabolism to burn down fat now I write about this in my book Eat to beat your diet and if you guys haven't seen it this is what it looks like all right eat to beat your diet um it's got a lot of pages but the key is that there's a lot of tables and charts of foods that can activate your metabolism so yes you can eat to burn down harmful body fat and elevate your metabolism all right so I'm going to tell you that some of the foods that you should be eating to activate your metabolism are beans legumes uh White beans kidney beans red beans Pinto beans uh you name it gigantic fava beans all great okay uh soybeans chickpeas lentils these actually um uh these Foods these beans and legumes can actually activate your metabolism another category of food that can activate your metabolism are Brasa vegetables Brasa vegetables are the ones that have a slightly sulfurous taste you know broccoli kale Buck Choy cabbage cauliflower all those types of um Swiss chard those types of Braska uh really do a great job uh of activating our metabolism they activate our Brown fat which burns down harmful white fat so you're B you're you're you're charging supercharging your metabolism I have a video on uh many videos actually talking about Brown fat and white fat in a nutshell Brown fat is good fat white fat can be bad B fat if we overeat it it grows up too much and when we eat foods like Brasa that contain a bioactive called s suanes they activate the brown fat it's just like in a a kitchen where you've got a gas range you go click click click whoosh now you can cook your soup or boil your water all right well in your brown fat when that happens click click click whoosh you're eating the broccoli so fanes are activating the brown fat that brown fat like your uh range is on fire it's generating heat it's called thermogenesis now on your stove in order for your uh gas range to generate heat click click click whoosh it's got to draw gas from someplace it gets it from the gas line maybe you got a tank in the side of your house or maybe you've got gas coming from your street lines well in your body when your brown fat goes click click click whoosh because you've eaten Brasa vegetables with the sophanes it's it's heating up thermogenesis where're is the fat Brown fat drawing that energy from the fuel from well it's drawing it from your white fat specifically your visceral fat so Brown fat can burn down white fat Brown fats good fat burns down excess bad fat white fat and Brasa can actually activate that and so can onions onions are alium alium actually belongs to a whole category it's a big umbrella onions scallion shallots garlic they all fall in this category they actually contain quatin quatin is another bioactive that you got it activates your brown fat click click click whoosh draws down that um uh energy and fuel from a harmful excess white fat tea can also do the same thing the cakin and tea so we're talking about egcg and uh turns on your brown fat to burn on your white fat uh and uh it's not just green tea not just matcha but it turns out that Wong tea which is the kind of tea you get in a Chinese restaurant often times jasmine tea can do the same thing even black teas like pu tea which is a fermented tea or Earl Gray tea black English breakfast tea they will all do the same thing so they can actually turn on your brown fat to burn down your white fat and guess what so can coffee with chlorogenic acid again back to the coffee back to the thing you start the day with and the tea end the day with now I'm telling you in the middle when you're eating choose some of these Foods the beans the Brasa the onions the carrots the tea the coffee and you're actually going to be practicing uh habits that are better for uh brain health as well okay now I can't let you forget that your gut health is connected to your brain health so if your gut isn't healthy your brain's probably not healthy as well uh and gut inflammation is such a huge deal and this is one of the reasons why you want to cut down on uh Ultra processed foods because many Ultra processed foods actually damage your gut bacteria which then makes unhealthy gut which then makes it difficult to have a healthy brain now what about a snack uh we talked about other Foods you want a brain healthy snack try eating tree nuts tree nuts uh of course if you're not allergic but most people are not tree nuts you know pecans almonds walnuts cashews macadamias even pine nuts all right nuts are a healthy source of of healthy fats good source of healthy fats and a source of dietary fiber good for gut health good for brain health all right and nuts definitely improve the microbiome and this and a good healthy microbiome guess what lowers inflammation lowers inflammation also good for the brain and good healthy gut bacteria help your brain secrete those neurotransmitters like dopamine serotonin oxytocin all helpful helpful for you to have a better mood good brain health good emotional health good mental health mental mental Wellness as well so gave you some foods that are actually good I'll give you one last tip about foods that are actually healthy are eat colorful Foods uh colorful foods are uh plant-based Foods you know you go to the produce section you look at your red bell peppers the green peppers you look at the orange and yellow peppers uh there's a whole variety of green that counts too it's green isn't just one color it's a whole bunch of different colors you can see in the produce section mix it up and the fruits of course uh seasonal fruits have all kinds of different colors just look at the berry section amazing those colorful bioactives in other words the natural chemicals that give the foods their colors actually activate your metabolism burn down harmful body fat and the polyphenols are good for brain health as well okay now if you want a basic basic basic beverage for B brain health I know we talked about tea I know we talked about coffee but but here is the most important tip I can give you don't forget to drink water water is the most popular beverage in the world and it's necessary to prevent dehydration of your brain really really important when your brain is really dehydrated okay it's in big trouble so you want to actually drink uh water enough water every day to kind of keep your brain watered so think about a plant that you might have in your kitchen window cell you going to put give it a little water you don't want to be too water logged and that that kill the roots um but you want to have just enough to be able to actually keep it alive and thriving in the sunshine and the same thing of drinking water now water is in a lot of things waterers in coffee waterers in tea but I'm bringing this point up because you can just drink regular old plain water now one little Caution about drinking water these days that we know look bottled waterers very very popular right like you go to any place you know if you're on if you're if you're taking a vacation and you're a tourist and you're going to go for a hike or you're going to go to the beach or whatever what are you going to get a bottle of water plastic container with water now we now know that the plastic sheds particles billions of particles into bottled water and that's not good so I urge you to drink water out of a glass if you can all right might not be possible and it's true we're surrounded by plastic anyway but that these this day and age if you know that plastic is found embedded in your blood vessels it's embedded in the brain it's found in your bloodstream I mean that's pretty scary and in fact Recent research has shown that um having plastic in the lipids that could be blocking your blood vessels increases your risk of heart attack or stroke by four times and they've been able to find plastic particles in testicles in seen and in the penis as well all right so that doesn't actually make you sit up and take note of that plastic water bottle I don't know what will hey there I want to share another resource with you my free resource on foods that can impact on brain health specifically Alzheimer's disease and dementias important research is helping us to appreciate that diet your diet can make a market difference when it comes to your brain health so I want to share three foods that you can add to your plate today that can help you avoid cognitive decline check out my resource available for free right now in in the caption below now back to the video okay so but drink water drink it out of a tap drink it out of a glass that's actually what you prefer it's good for your brain that's good for brain health okay and I'm telling you this because if you are thirsty you might have the temptation to reach for a soft drink a soda or fruit juice and in every single case a glass of water is going to be better than a soda regular soda sugar Sweeten beverage or a uh uh diet soda uh the water cup of water is going to be better for you and fruit juice look um who doesn't like fruit juice every now and then there's a lot of sugar in fruit juice all right and so it's always better to drink water every now and then you're going to have fruit juice I actually tell you just to have the whole fruit then you get the dietary fiber and all the polyphenols as well all right so we talked about have coffee in the morning uh tea in the evening we said watch your metabolism trying to elevate your metabolism we gave some specific foods that you can actually eat to um and beverages that you can to eat to uh enhance your metabolism uh and good for brain health fifth exercise exercise movement okay is good for the brain you know when they actually found what kind of movement one of the best kind of movements you can do until you're really quite old is dancing all right dancing happens to be something if you've ever seen go to if you look up on on YouTube dancing in China you will see people who are elderly doing ballroom dancing in public squares in the evening it's actually really delightful to actually see all right so but any kind of physical activity walking running you don't need to actually belong to a gym you don't need to actually hire a a trainer you could all right and you don't even need to own a bike or uh play basketball with your buddies but you want to stay in motion if you like to do all those sporty activities please do it play pickle ball whatever it is that actually keeps you in motion walking upstairs keep you in motion walking around your house when it's raining cats and dogs outside and you don't want to get soaked walk around the house that is staying in motion uh keeping in Motion makes for good circulation better blood vessel Health with better brain health right a healthy heart means a healthy brain all you need to do okay and this is I don't mean by all that's the only thing you need to do but what I'm saying is that staying in motion stay stay active do at least a 30 minute brisk walk every single day that should be your Baseline that's a great way to actually stay in Baseline shape and the reason I say that is because a lot of people go you know what I'm not used to working out I don't know if I can get to doing it I don't want you to actually go try to work out like crazy which might not be good for your heart anyway um suddenly and then say you know what a week of doing it I can't do do this anymore I quit I'd rather have you walk regularly uh after dinner you know uh just walk off with some of the food that you ate um you'll actually be more relaxed uh in the evening and may probably get a better night's sleep anyway um uh in the evening or you can take a walk in the morning too if you can squeeze it in your morning routine that is a great way you know it's not too hot yet you can go out get some sunshine vitamin D all those kinds of things some fresh air all right um that's all good so uh these are just little tips of staying active all right we talked about five things are good for brain health Five Habits now I just want to actually close by saying a few things that you want to avoid if you want to keep your brain health things you want to avoid for better brain health all right first don't drink alcohol regularly now I know alcohol is part of our society so that's why I think I don't I don't scold people about drinking alcohol but you should know that alcohol is a toxin and your brain is especially sensitive it kills your neurons so you kill a little brain cells every time you have a drink look the brain is pretty resilient it'll bounce back but this is why you shouldn't be drinking it regularly you don't want to stun your brain every time you sit down for a meal all right and or drinking outside of a meal too all right so I I I think that uh there's a myth by the way that a glass of red wine is good for you look here's what's the case red wine tastes great it's part of it's a it's a fine beverage to have you know for social events but there's nothing healthy about it the alcohol and the red wine the thing that gives you a buzz kills brain cells so if you want healthy brains cells don't drink regularly by the way Step Up A Notch to hard liquor now you're talk about a really really um hard-hitting poison for your brain all right hard liquor whiskey vodka and you know all those kinds of hard Liquors are really a deadly toxin to your brain so if you're going to have it what I say is have it in company don't ever drink alone uh have it in the context of Celebration or recognition an event that's actually fine I I think in moderation a lot of moderation um but don't drink regularly and don't drink alone all right just remember alcohol is a brain toxin there's no way around it it just is second thing you want to avoid don't eat too much salt now salt tastes good salt you know you get popcorn you going to put some solar it that makes it a lot tastier and that's why at a restaurant you ever watch in an open kitchen pay attention next time you're at a restaurant where they have an open kitchen or maybe a Food Channel and you watch somebody sprinkling salt in chefs pick up a lot of salt and they sprinkle on because they know salt makes taste food taste good before it actually gets too salty it just keeps on uping the ante of making the food taste good but here's the deal salt raises your blood pressure raising your blood pressure actually uh uh can damage the lining that that ice skating rink of your blood vessels guess what now clots can actually form that's why high blood pressure hypertension is a silent killer it sets you up for stroke okay uh increases your stroke risk so just keep your Sal to levels I would say enough to make your food taste good don't put extra salt uh down as a reflex by any means okay and by the way you can also get low sodium uh things if you're buying it from a store and if you are eating in a restaurant and the food is too salty please send it back and tell the chef that they put too much salt in it and they'll bring you back another one that doesn't have as much salt like I think the chefs need that feedback uh uh and uh in order to be able to give you a healthy enjoyable meal all right you can also ask the chef that cook make a low low sodium low low salt version you don't want to increase your risk for stroke all right now the other thing you want to avoid is eating Ultra processed foods I told you about this already Ultra processed foods damage your gut health poor gut health as poor brain health enough said uh there's a lot that can be talked about with ultra processed foods but you don't want to have that disbiosis or sick gut bacteria which can definitely impact on your um brain health now the last thing you want to actually avoid is screwing up your sleep all right uh sleep is really important for brain health there is uh a uh sewer system in your brain called the glymphatic system it's like the lymphatic system it carries fluid in your brain the glymphatic your system is like the Paris sewers um which again in Paris there's a an extensive series of underground sewers that keep the city above uh the street level clean all right and what the what brain does too with the glymphatic system is at night when you actually are sleeping deeply the sewer system opens up and you drain your brain out of all the toxins that have accumulated during day so if you want good brain health you want to actually have good sleep as well sleep hygiene is a topic I'll I'll do for another video but in order to sleep well here's one critical tip and I know this is difficult to do even for me all right so I'm just telling you it's hard for me but it's really important if you want to get good sleep don't expose your eyes and hence your brain right your eyes are just part of your brain to Blue Light that comes from a screen like a phone before you sleep you kind of want to actually like I said this is difficult for me to do too you kind of want to put down your screens for about two hours before you go to bed at night I know you're saying good luck ply but please try to do that um and because it'll actually help you get a better night's sleep better night's sleep your lymphatics open up you're draining the toxin from your brain and then the next morning you're actually going to feel better all right that's actually um uh really really important if you don't you're going to have be brain foggy right not surprising because you're toxins are still uh in your sleep the other thing you want to check out is that you might actually have sleep apnea that can interfere with sleep so if your bed partner says that you're snoring all the time doesn't matter if you're a big person or you're a skinny person uh the tissue in the back of your throat can enlarge by the way excess body fat over consumption uh one of the first places that uh you can actually grow extra fat is in the back of your tongue by your throat you get a fat back of your tongue uh when you're sleeping and relaxed it can collapse and you can actually have sleep apne you're not going to sleep well because this fatty tissue is going to collapse and you're going to wake up startled and you're never quite getting enough sleep because the fatty tissue in the back of your throats um actually blocking uh your ability to get enough oxygen so you're waking up all the time all right you won't even know it you're just waking up all the time and you're snoring at the same time because all that fatty tissue is is just um creating that funky snoring sound when air is going in and when air is going out all right this is a medical issue sleep apnea you'd want to talk about it with your doctor there's a sleep study and sleep apnea is treatable so something that you should um think about one thing that you can do to reduce the consequences of sleep apnea is to improve improve your metabolism lower that body fat uh and that actually can actually improve sleep apnea as well now I write in eat to beat your diet again this book about um uh reducing tongue fat it's an interesting little side fact I'm not going to spoil it here you got to read the book and check it out eat to beat your diet um and I talk about um how to actually how tongue fat actually builds up uh even in skinny people so I think that's it we talked about five things to do we talked about a bunch of things not to do for brain health I hope you learned a few things I'll see you again uh for the next video hi there have you enjoyed watching this video I know you'll love the next one stay here and check it out and I'll see you there
