How the food you eat affects your brain – Mia Nacamulli

Your Brain on Food If you sucked all of the moisture
out of your brain and broke it down to its constituent
nutritional content, what would it look like? Most of the weight of your dehydrated
brain would come from fats, also known as lipids. In the remaining brain matter,
you would find proteins and amino acids, traces of micronutrients, and glucose. The brain is, of course, more than
just the sum of its nutritional parts, but each component does have
a distinct impact on functioning, development, mood, and energy. So that post-lunch apathy, or late-night alertness
you might be feeling, well, that could simply be the effects
of food on your brain. Of the fats in your brain,
the superstars are omegas 3 and 6. These essential fatty acids, which have been linked to preventing
degenerative brain conditions, must come from our diets. So eating omega-rich foods, like nuts, seeds, and fatty fish, is crucial to the creation and maintenance
of cell membranes. And while omegas are good fats
for your brain, long-term consumption of other fats,
like trans and saturated fats, may compromise brain health. Meanwhile, proteins and amino acids, the building block nutrients of growth
and development, manipulate how we feel and behave. Amino acids contain the precursors
to neurotransmitters, the chemical messengers that carry
signals between neurons, affecting things like mood, sleep, attentiveness, and weight. They’re one of the reasons we might feel
calm after eating a large plate of pasta, or more alert after a protein-rich meal. The complex combinations
of compounds in food can stimulate brain cells to release
mood-altering norepinephrine, dopamine, and serotonin. But getting to your brain cells is tricky, and amino acids have to compete
for limited access. A diet with a range of foods helps
maintain a balanced combination of brain messengers, and keeps your mood from getting skewed
in one direction or the other. Like the other organs in our bodies, our brains also benefit from a steady
supply of micronutrients. Antioxidants in fruits and vegetables strengthen the brain to fight off
free radicals that destroy brain cells, enabling your brain to work well
for a longer period of time. And without powerful micronutrients, like the vitamins B6, B12, and folic acid, our brains would be susceptible
to brain disease and mental decline. Trace amounts of the minerals iron, copper, zinc, and sodium are also fundamental to brain health
and early cognitive development. In order for the brain to efficiently
transform and synthesize these valuable nutrients, it needs fuel, and lots of it. While the human brain only
makes up about 2% of our body weight, it uses up to 20% of our energy resources. Most of this energy comes
from carbohydrates that our body digests into glucose,
or blood sugar. The frontal lobes are so sensitive
to drops in glucose, in fact, that a change in mental function
is one of the primary signals of nutrient deficiency. Assuming that we are getting
glucose regularly, how does the specific type
of carbohydrates we eat affect our brains? Carbs come in three forms: starch, sugar, and fiber. While on most nutrition labels, they are all lumped
into one total carb count, the ratio of the sugar and fiber subgroups
to the whole amount affect how the body and brain respond. A high glycemic food, like white bread, causes a rapid release of glucose
into the blood, and then comes the dip. Blood sugar shoots down,
and with it, our attention span and mood. On the other hand, oats, grains,
and legumes have slower glucose release, enabling a steadier level
of attentiveness. For sustained brain power, opting for a varied diet of nutrient-rich
foods is critical. When it comes to what you bite,
chew, and swallow, your choices have a direct
and long-lasting effect on the most powerful organ in your body.

  1. These ted explanations are nice and all, but it greatly magnifies things. When they say, food has an effect on your mood, how big is this effect? Is it even worth worrying about? Thats the questions i want answered

  2. Excellent video, thanks! So, if I understood well, all those new "carbohydrates-free" diets are not really good for our brain, isn't it?

  3. I feel like I'm the only person that thinks it's easier to eat healthy during school than on the weekends.
    Bring your lunch! Bring some cheese, vegetables, and some nuts! Boom you got a delicious healthy lunch!

  4. Do not eat fish. It’s not even funny how polluted they are nowadays. Even radioactive material is found in many fish.

  5. Saturated fats, dangerous to the brain? Are you joking? We would be idiots from the start. Heated vegetable fats on the other hand, that’s very bad.

  6. The link between antioxidants and free radicals have never been proven inside the human body, yet you state it as if it is true?

  7. No one is absolutely wrong.

    Everyone is sharing their own views on a topic which is very deep, but has no correct answer. At least, not for now. Of course, when the mordern science is modified more and more(alliteration) and we do not destroy ourselves, then we will surely be able to someday answer "this comment".

    The question : "Are we a mind with a body or a body with a mind"

    (Mind is not the same as the brain, if someone has any confusion)

    The only thing I regret is the way the public has again and again given replies like : "You are wrong", "You are absolutely wrong" or "learn to take a joke".

    Many theories have been proposed from a long time and many of the have been proved not so correct, but that's how science grows. It is cummulative.
    I wish everyone to plz question every form of information given to your be your respective educational systems, because you never know how one question might change the course of human scientific endeavour / journey.

  8. Sir Does cashew nuts badams ,affects 60 year old man brain nd bp person pls father suddenly loss his short term memory.

  9. What does a brain that's been on anti-cholesterol drugs for 10 years look like. Because they block nutrients/fats to the brain? Does it shrink? Is that why more people have parkinsons and alzheimer's disease that ever before because everyone is on them? Scary.

  10. 50% australians have diabetes thats lack of knowledge and booming business,like cancer 170 billion a year its all scientifically made to do us over not i.

  11. But you don't explain what we are looking for, if we want this in life we need to eat this etc.
    You should do a video to complete.

  12. I used to think that I had Seasonal Affective Disorder (S.A.D.), a problem that makes you feel depressed when the weather's no good, but then I cut sugar out of my diet (aside from whole fruits) and I realized I do not have S.A.D. Essentially, sugar was negatively affecting my mood… now, I'm pretty much happy all the time, even on gloomy days!

  13. EPIC Norfolk study showed ALA to DHA conversion is increased in vegans. So basically Omega 3 is higher in vegans than in fish eaters, because the body adapts to convert more. If you look at all of the studies there is overwhelming evidence that plant based diet is the most healthy, and eating animal products leads to all kinds of cardio-metabolic illness, degenerative disease and cancer. Animal agriculture is also destroying the environment, and the oceans could be dead by 2050 if things don't change. We all love animals, so how can we justify causing them harm, and causing such harm to our environment and our bodies just because we like how they taste? Go vegan. It's as easy as choosing plant milk at the supermarket. Eating a few spoonfuls of flax seeds a day for omega 3. For your health and the health of your family, and the future of our planet, and the well-being of the animals, eat more plants and cut out animal products.

  14. It’s completely false that meat is protein. Basic science. Our bodies and animals bodies can’t naturally produce protein and need to eat plants or greens to begin the protein breakdown process. So when you eat an animal the protein you’re getting is recycled protein from plants. However, when I eat my protein as a vegan, I am eating the direct source of protein which Ian obviously healthier and much higher in protein than meat. Just a fun fact

  15. While watching this video, I was inspired to make myself a healthy smoothie (although I believe chewing food is better) instead of eating other snacks. I liked the animation.

  16. Go vegetarian !!
    Pls for animals sake do not cut their bodies and fry eat them no no pls no have some mercy its a request I know u will one day go completely vegetarian and u will be relaxed and will never have guilt in ur mind that u did something cruel !

  17. I haven't been taking omega3 pills for 1 year. Once the video has finished I got two of them and I decided to get it every day. Thank you.

  18. We don't actually need sugar right? So , if I don't eat sugar ever again in my life, I wouldnt have carb deficiency right?

  19. So true. This applies to diseases such as depression; always better to use natural remedies instead of potentially dangerous medication. Luckily there is a lot you can do to figure out the root causes and use natural antidepressants such as the omega 3 fatty acids mentioned in a study!

  20. Awww how refreshing. A nutritional video on YouTube where I agree with everything said. Thanks teded. Awesome as always

  21. Okay, but what happens if you don’t eat? Just eat until your full for 1 day then go 3 days without and then repeat.
