Kind: captions Language: en today I'm going to talk about the healthiest vegetables I look for when I go shopping in the grocery store these are the foods that fight disease and specifically fight inflammation the first one is the Tomato some of you might think that Tomatoes a vegetable right but it's actually a fruit and tomatoes are pretty wonderful because not only they taste good but they've actually been shown to lower the risk of prostate cancer and breast cancer so how does it do this well to Tomatoes contain bioactives and the secret to Health in Foods is often the bioactive one of the bioactives in tomato is uh vitamin C vitamin C is a powerful anti-inflammatory substance another bioactive in tomato is called lopine which is a carotenoid lopine does a lot of different things that are beneficial for the body one of them is that lycopene protects our DNA against damage from oxidative stress including Ultra vet radiation like sun damage that's right eating tomatoes with the lopine can protect us against uh damage from the Sun that means kind of like sunscreen but from the inside out so sun exposure can damage your DNA lycopene protects your DNA against the sun damage and you can actually eat tomatoes in order to be able to protect yourself and protect you from the inside out from sun damage coming from the outside now how do I like to eat tomatoes I like to eat tomatoes raw sliced into a salad um absolutely great way to get great flavor great hydration and a vitamin C is really good but if you want to get the most out of lopine okay that is that antioxidant that's the one that helps to protect your DNA you want to actually make sure you get as much lopen as possible how do you get the most lopen out of a tomato well you want to actually heat it like cook it saute it uh in a pan and so you're actually cooking Tomatoes like a tomato sauce all right like a Sugo and add a little bit of extra virgin olive oil so here's what happens the heat from cooking converts the chemical structure of lopine okay which is natural into a slightly different chemical structure also natural that your body loves to absorb so you when you cook Tomatoes you actually get more lopine that's easier for your body to absorb add a little bit of extrav Virgin Olive Oil you know why because lycopene is what's known as fat soluble which means that lopine likes to dissolve in oil but you actually cook tomato sauce the lopine converts into the part your body likes it and you mix with the olive oil now it really gets absorbed uh into uh your body very very easily that's why by the way the Mediterranean diet is so healthy and it's got so many tomato recipes in it usually the tomato is cooked all right now there are many varietal of tomatoes out there if you go to your grocery store in a summertime or you go to the farmers market it's almost overwhelming how many different types of tomatoes there are you'll see so many options so I always ask which one should I buy right so if you're sort of looking from The Culinary side I'll leave it up to you to figure out which one tastes the best but I'll tell you when it comes to health the best tomatoes are called San Marzano Tomatoes which is a kind of Plum tomato originally from the town of San Marzano which is on the slope of a volcano called vvus near Naples Italy and you can often find San Marzano tomatoes grown outside of Italy um uh and you'll find these in the Farmers Market or even the grocery store but if you can't find fresh San Marano you can easily find canned San Marzano tomatoes in the middle aisle of the grocery store and it turns out that canned San Marzano Tomatoes whole or pureed Tomatoes still have the good stuff the lopine and Sant Marano Tomatoes just have higher amounts it's one of the most potent when it comes to uh lopine another potent uh tomato that you can actually defitely find in your grocery store are these little tiny cherry tomatoes they are like lopine bombs they're really packed with the lopine all right um so they're small but they're really really powerful you actually want to cook with uh cherry tomatoes what I like to do I like to sear them so you heat some olive oil a little bit of garlic all right and when the oil is hot and flavored with the garlic just throw some cherry tomatoes in there and you'll see them ballister pop and they'll start to cook down makes for a really wonderful uh tomato sauce the next vegetable I want to talk about is a whole group of Greens Greens that are known as Brasa now Brasa you might have heard of that's because a bunch of healthy greens belong to them broccoli broccoli Rob kale cauliflower cabbage colled greens mustard greens now these Brassica vegetables contain bioactives called itc's this stands for isoo cyanates isothiocyanates itc's and these are the bioactives that are responsible for the characteristic flavor of Braska vegetables little sulfurous little sharp slightly bitter taste bitter usually means better when it comes to your health right and that's what Brasa vegetables do so what do itc's isothiocyanates do in the body well they are potent anti-inflammatory bioactives and they also help to improve your circulation they improve androgenesis that your body's Health defenses and they can actually improve your immune system as well and if you want to get the most of these itc's from Brasa plants here's a couple of things you want to do you can cook them quickly don't overcook them or you'll degrade the itcs and when you eat them and you want to make sure they're tasty right you can only eat so much raw broccoli which most people don't do but if you blanch it quickly sauté it then it actually becomes something really delicious and here's what you want to do when you eat them you you want to make sure you chew them and the reason that you want to chew your vegetables is that the itcs the good stuff is locked inside the cell of the plant right plants have cells just like humans have cells but human cells are soft and Squishy plant cells are rigid and boxlike it's like a it's like a like a shoe box all right and you want to break that shoe box open in order to be able to release the itc's and other enzymes so when you chew your broccoli what you're doing is you're breaking open The Shoe Box containing the itc's and you're releasing also an enzyme can Mosin and this enzyme M usinas breaks down the itc's and generates sophanes and the sophanes then go on to when you swallow them go on to uh stimulate your health defenses all right so this is how it works pick the Brasa from the field bring it back you can blanch it cook it quickly uh my little tip for cooking Brasa is if you want to cook it it should be brght bright green brighter than when you actually had them raw and then stop all right before they start to dull in color that's when you've overcooked them that's why the old kind of school way of boiling your vegetables pretty much destroyed when it comes to broccoli for example you've just destroyed all the itc's all right so how do I actually like to cook them you can steam them get steam of broccoli like in 10 minutes you're done okay you can blanch them blanching as I mentioned to you boil some water wash your vegetables all right like broccoli broccoli Rob quickly throw them into the boiling water all right and in 60 seconds fish them out drain them you can even rinse them under some cool water if you want to stop the extra cooking it should be bright green all right then cut them up if you want and then you can heat up a pan and sauté them a walk to stir fry them uh uh or you can put them into a food processor and puree them all right and obviously food processor like super chewing you're going to get a lot of those itc's out all right you can make a delicious soup or smoothie uh that way now I actually like broccoli soup as an example uh in my book eat to be disease I had a whole recipe for broccoli soup flavored with oregano dried spice absolutely delicious so you should check it out the third disease fighting food I want to talk about is the green bean Yep this is the legume that was once served from the can and baked into cassero with fake fried onions all right but in many healthy cultures like in Asia and the Mediterranean as well as in Latin America this Bean the green bean is a staple food uh that also improves health and is really great for nutrition now why nutrition well it turns out that beans are packed with protein as well as dietary fiber and we all need protein especially as we get older but this is actually a great source of protein especially if you're a vegetarian right and green beans are known by their Latin name in case you didn't know this called pholis vulgaris and green beans also contain polyphenols and the reason I mentioning the Latin name if you want to look this stuff up yourself you can go to PubMed okay pme D that is a database of all the research have been done look up fasolis vulgaris and look up polyphenols and you'll be able to see all the different research that's been done on green beans and the polyphenols that they include so what are some of the ones that have been discovered in green beans fol cortin metin pro pro cyanidins there's a lot all right little lowly green bean is packed with power when it comes to polyphenols now almost all these polyphenols are anti-inflammatory so eating green beans is a great way to lower inflammation in your body and these bioactives also activate your body's Health defense systems they kind of raise your Shields now green beans also have antioxidant properties that have been shown to protect your stem cells that are naturally present in your body so we're all born with about 70 million stem cells that all get packed away like in a suitcase and stored in our bone marrow and our body fat and our skin and different organs and when we actually need to repair our organs From the Inside Out you won't even know this is happening these stem cells come out to affect repair so green beans actually help to protect our stem cells so that our regenerative power is uh longer better faster all right so green beans actually protects these stem cells so they allow our stem cells to stick around longer and work faster and better and that's one of the benefits of uh green beans so by protecting stem cells from oxidative stress these are free radicals that can damage your uh stem cells green beans are regenerative Foods now in my book Eat to beat disease I also write about more than 30 other foods that actually can support tissue regeneration so you're interested in regenerative foods go get my book e to be disease you'll see them in one of the chapters uh specifically on foods that stimulate regeneration now back to green beans you can find bean green beans in a can but these are usually limp and flavorless so I recommend that you don't use canned green bead all right get them fresh when you get them fresh they're like in separate beans sometimes are on a stem you want to look for the ones that are green have a long pod and a little bit of stiffness if they're too bendy now they kind of passed their prime a little bit of stiffness all right and you can eat them raw uh I remember going to a farmer's market to a Grower's Collective and literally you can pick out the beans off the stocks and bite them and you can eat them right then and there really delicious actually but if you want to cook them one of the things you want to do is uh trim off the ends or the beans just use a knife and cut off about a quar inch don't cut off too much um uh and uh and then you can cook with those now some beans are known as Haro ver harco ver these are the french green beans they're a little bit uh thinner uh they taste great they're a little earthier less sweet than the classic American green bean but they're all great I'm just telling you this because there's different types you can get and I don't want you to miss out on haraca because you don't recognize them as green beans they do look a lot like green beans so here's how I cook green beans look I cook them by blanching them boiling water throw them in after I cut them off and wash them all right blanch them 30 seconds that's it and take them out to stop the cooking and then uh what you can do is you can sauté them in a pan with a little bit of extra virgin olive oil or garlic or throw them into a walk and stir fry with your favorite sauce oyster sauce soy sauce um a little bit of shaing rice wine you can make it really really delicious uh you can also add other proteins in it to it as well or make a vegetable stir fry guarantee you green beans can make a tasty dish not just for the holidays but of course you can use them for holidays they're part of your family tradition but green beans are good for everyday meals and by the way once you cook um some green beans you can cool them off store them in the fridge you can add them to salads all week long so you can get green beans all year round at the grocery store but the best time their season is actually from late spring into late summer and you'll find them in farmers market so that's the best time to go uh through them right sort through them look for the ones that aren't marked up but aren't too soft um and just put them into a bag take them home and have a great tasty meal the next food we're going to talk about are mushrooms now people are either mushroom lovers or they're not so big fans of mushrooms I happen to love them I love mushrooms in soups stews with pasta saute on scrambled eggs so many different ways to actually make mushrooms um and in addition to their Great Taste mushrooms have great health benefits all right and this is because of the bioactives that are in mushrooms one of them is called beta d D glucan and this is the form of soluble fiber that has multiple benefits beta glucan has been shown by researchers to improve your circulation it helps healthy androgenesis and the vascular endothelial cells that line your blood vessels beta glucan is very helpful for that and beta glucan when you have a wound can speed up angiogenesis this is the sprouting in new blood vessels that can help you heal wounds in fact part of the research I've done shows that beta glucan speeds up wound healing by by uh recruiting stem cells from the bone marrow to contribute to regenerating the wound stimulates androgenous Sy to actually better circulation to the wound and then Zips the wound Shut by closing it at the very top all right so beta glue can from mushrooms is uh supports healing and circulation beta de glucan has another property that's the complete opposite of wound healing and that is beta glucan can starve cancers by cutting off the blood supply to cancers this is called anti-angiogenesis all right and we've actually done research on this to show this uh can happen as well with mushroom deriv beta de glucan beta glucan is also a powerful anti-inflammatory so if you want to fight cancer you want to lower inflammation of the body if you want to fight the diseases of Aging you want to lower inflammation and beta de glucan because it's a solop fiber feeds your gut microbiome healthy gut bacteria wellfed gut bacteria lowers inflammation boosts immunity helps you speed healing and also text messages your brain so you're in a better mood as well all right so many great uh benefits of eating mushrooms by the way mushrooms are also a great source of vitamin D vitamin D for David actually is also key for healthy uh bacteria but it's also key for building healthy bones as well and vitamin D levels in the blood are also linked to lower risk of cancer as well by the way here's a pro tip if you want to get get more vitamin D out of your mushrooms what you want to do is just slice the mushroom lengthwise put it on a cutting board lay them out and put them in front of a window with sunlight coming into it and sunlight hitting the mushroom will do in the mushroom what sunlight does when you expose your skin to sunlight it causes the mushroom to produce more vitamin D you know how we say if you want to go out get some sunshine it'll help your skin produce V vitamin D same deal in a mushroom pretty amazing takes a few hours but give your mushroom a suntan um before you actually cook it they will get a little more vitamin D out of it hey there I have another resource to share with you it's my free guide to foods for your gut brain axis in case you haven't heard we now know that feeding our gut microbiome that's your Healthy gut bacteria is one of the most important things you can do to lower inflammation and improve overall health in your body including brain health and we're just beginning to learn how taking care of your microbiome reduce your risk of developing heart disease dementia cancer and many other serious inflammatory conditions so you don't want to miss out on my guide because I give you five food recommendations that you want to eat right now that will help optimize your microbiome and protect your gut brain access check out this resource it's available for free right now in the caption below now back to the video all right now the other kind of pro tip I'll give you is if you're going to use mushrooms I strongly recommend that you stick with culinary mushrooms culinary meaning related to cooking right white button mushrooms shitake mushrooms Mitaki mushrooms oyster mushrooms inoi mushrooms beach mushrooms portella porini morels a whole bunch that you would actually see chefs working with or homecooks all right these taste great and they actually have beta de glue can all right for good eating I don't recommend that you use medicinal mushrooms now medicinal mushrooms become very popular recently you know Lion's man Corps turkey tail they're kind of bitter they don't taste that great honestly but here's the thing for thousands of years the medicinal mushrooms have been not used for food all right there's probably a reason for that but rather they've been used by traditional healers for traditional medicines like traditional Chinese medicine all right and the experts apply them to actually treat specific diseases so sure you can eat those medicinal mushrooms Lion's man I've seen recipes for actually roasting them it probably tastes pretty good in those recipes but I recommend that we leave medicinal mushrooms to the healers all right leave the medicine to the healers and leave the culinary stuff because it still has um that Bic glucan for ordinary food finally let's talk about carrots carrots are one of my favorite foods as well get them in the grocery store all year round H and I used to think by the way carrots were not that great I used to think of them as rabbit food food right if a pet rabbit you feeded them some carrots but guess what carrots are really really delicious and they also have a lot of dietary fiber and carotenoids not surprisingly the name carotenoids carrot they're similar these carotenoids get into your body and they help feed your gut microbiome along with a dietary fiber dietary fiber and coronoids lower inflammation all right um and they boost immunity to help protect you against infection and the carotenoids also powerful antioxidant properties that can protect your DNA from damage coming from the environment so what kind of damage am I talking about you know toxins that you might breathe in or be exposed to radiation like uh radon coming from uh the Earth you can't stop that off gasing what you been talking about new furniture new carpet new car all that uh lovely smell that we associate with new stuff hey those are solvents that are off gassing they damage our DNA and of course environmental pollution unfortunately we're surrounded by it so carrots by protecting our DNA From the Inside Out actually um helps us counter the effects of what we might be exposed to in the environment now how good is carrots and how do we know that it works in people well study from The quadrum Institute for biosciences of the United Kingdom looked at 64 subjects adults and fed them the equivalent of 2 and A2 cups of carrots that's about five mediumsized carrots per day all right and by the way the carrots were actually Frozen carrots that they could buy in a grocery store so just know it's really easy to get these carrots and they were cooked for for 10 minutes in boiling water then they were minced up in the food processor before being fed to the subjects and what the researchers did is they analyzed the blood from the subjects before the study before they ate carrots and then three weeks after they were eating carrots and then at six weeks after that so here's what they found as soon as 3 weeks after starting car started eating the blood of the subjects in this research had more DNA repairing activity than before they started eating carrots meaning that from compared to the beginning of the research study they had more DNA protecting power just three weeks later all right now this is something else that you might not know about carrots is that carrots were not originally orange the original carrots were purple well actually they were purple on the outside and kind of yellow on the inside if you stapped them in half you'd see a purple ring and then the inside of it would be bright yellow so how did carrots become orange well in the 17th century farmers in the Netherlands Dutch Farmers began breeding carrots so they were mostly orange and the legend goes that these farmers were paying tribute to William of Orange the Dutchman who helped to free the Netherlands from Spanish rule and that started this Cascade of enthusiasm to have orange carrots all right so what do we talk about today Tomatoes Brasa green beans mushrooms carrots I hope you
