Benefits of Blueberries for the Brain

August 25, 2019


[Music] when you search the medical literature for studies on berries papers like this pop up a blueberry muffin rash or pictures of strawberry tongues or as a way to describe stool appearance those stools truly resembling currant jelly are not very common what is it with pathologists love affair with food terminology the grossest of which may be the way amoeba chest infections are described where you spit up pus that looks like anchovy sauce which sounds gross even without the pus there are actual Studies on berry supplementation like how they can mitigate the negative effects of a high saturated fat died on the brain and behavior but that was in mice may be a better way to mitigate would be to not feed your pet mouse a stick of butter in the first place then there are studies on proprietary berry based nutraceutical supplements purported to improve cognitive performance see how there’s steeper rise in the supplement group old hats will instantly recognize this as the timeless trick featured in the 1950s classic howdah lie with statistics see how they don’t start the y-axis at 0 that’s to inflate the appearance correct the graph and you can see the effect doesn’t quite look so impressive there are studies of actual berries on actual humans but when they’re funded by berry industry trade groups you get studies like this an afternoon snack of berries reduces subsequent energy intake great but that’s compared to candy strawberries raspberries blackberries blueberries fantastic compared to a handful of jelly babies which are just like coated gummy bears – berries offer so little that you have to compare them to candy to make them look good there was that famous Harvard study I did a video about where berry eating appeared to delay brain aging by up to two and a half years but you don’t know if it’s cause and effect until you put it to the test and blueberry supplementation was able to improve memory and older adults in just 12 weeks time but that was feeding them up to 6 cups of wild blueberries a day now this was a proof-of-concept pilot study just see if they get any effect right we just didn’t have any studies using more realistic doses until now how about just a cup of day of blueberries they found that the addition of easily achievable quantities of blueberries to the diets of older adults can improve some aspects of cognition like long-term memory in terms of the number of errors the placebo group got worse the blueberry group got better you can even correlate the cognitive improvements with enhanced brain activation using fancy brain scan technology to actually visualize the improved blood flow to those same regions of the brain caused by the blueberry consumption does it work in kids too blueberry treatments have shown positive effects on cognition in both rats and adult humans but do these benefits transfer to children human children how about a randomized double-blind placebo-controlled study comparing about a couple blueberries to two cups to 0 cups what did they find cognitive performance improvements across all measures and the more berries the better and this wasn’t after 12 weeks of eating berries but within hours of just a single blueberry meal sounds like a good breakfast any day our kids are having their exams [Music] you

    Dr. Greger could save a lot of time and money by just telling everyone to go on a raw food diet.

    Those blueberries in your picture are not natural. I have consumed real natural blueberries and I know what theyre like. These ones in the pic are acidic in taste. The purple juice is totally unatural. Some are also slightly green. The meat should white, juiceless, have specific blueberry taste and a couple cups of them should be like a mild pre-workout powder. They should also boost vision like – Immediatly!!!. Those purple weakling, acidic and almost tasteless "blueberries" are an attrocity of modern agriculture.

    It isn't just blueberries it is ALL BERRIES. Listen to Dr. Robert Morse.

    Additionally, all of you who are still eating cereal with your blueberries are dampening the effects of the blueberries. If you want the benefits, eat them by themselves or with other berries/

    Eating a WFPB diet will prevent the cognitive decline in the first place. Stop the arteries in your brain from clogging and you won't need cups of blueberries to delay the decline by only 2.5 years. You won't have much of a decline to deal with ……ever.

    .++ RWS THE LIAR THE TROLL
    Position of the American Dietetic Association: vegetarian diets.
    It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes. A vegetarian diet is defined as one that does not include meat (including fowl) or seafood, or products containing those foods. This article reviews the current data related to key nutrients for vegetarians including protein, n-3 fatty acids, iron, zinc, iodine, calcium, and vitamins D and B-12. A vegetarian diet can meet current recommendations for all of these nutrients. In some cases, supplements or fortified foods can provide useful amounts of important nutrients. An evidence- based review showed that vegetarian diets can be nutritionally adequate in pregnancy and result in positive maternal and infant health outcomes. The results of an evidence-based review showed that a vegetarian diet is associated with a lower risk of death from ischemic heart disease. Vegetarians also appear to have lower low-density lipoprotein cholesterol levels, lower blood pressure, and lower rates of hypertension and type 2 diabetes than nonvegetarians. Furthermore, vegetarians tend to have a lower body mass index and lower overall cancer rates. Features of a vegetarian diet that may reduce risk of chronic disease include lower intakes of saturated fat and cholesterol and higher intakes of fruits, vegetables, whole grains, nuts, soy products, fiber, and phytochemicals. The variability of dietary practices among vegetarians makes individual assessment of dietary adequacy essential. In addition to assessing dietary adequacy, food and nutrition professionals can also play key roles in educating vegetarians about sources of specific nutrients, food purchase and preparation, and dietary modifications to meet their needs.''

    There is a gentleman Yosef, he has a farm in Peyton Colorado U.S. Ahavah Farm, he Farms completely chemical-free, which means he cannot be classified as an organic farm. But he supplies the best vegetables I've ever tasted in my life, and on the Brix scale he's getting higher numbers than what you find in the store. I'm wondering if this would translate into healthier food. It would be awesome to see him scale up to feed tens of thousands which he is talked about. But his customer base and funding is not there at this point in time. But this would be an interesting thing to see a study done on. And since organic does use chemicals I'm pretty sure there hasn't been a study done on chemically free food compared to intentionally sprayed food.?
