Feeding immunity

- For the immune system, fighting infections is like running a marathon. You can’t buy super fast trainers for your T cells, but can changing your diet change your immune response? Lydia Lynch’s lab at Harvard is looking at how what we eat effects what our immune cells can do.

"Just make sure you give the scientists a decent lunch at the conference"... lol
Broca's. By the way, I have difficulty communicating because I had a stroke in Broca’s area, the part of the brain that controls speech. 2/8/2021 but I lived again. (My wife helped me compose this.)
100 percent....our foods and air we intake,
Feeds are Cells,
It makes sense

I literally ate a honeybun as I watched this lol. 🙄 thanks for the reminder that I really do need to eat better and maybe now I might, 🤷🏻♂️, that’s for me to find out as well lol. Anyhow, I think this is one of those things we chose to unremember somehow. Like we just slowly forget about the fact that we do remember something until one day, we have that “oh, now I remember” moment. Where the hell has that memory been all that time?
~ I gotta eat more veggies
Sometimes you actually do understand it and still choose to die a bit more
I've heard often that sugar abuse causes cancer. My intake has been drastically cut back for years now, right after I read about it.
Can you provide some data, perhaps some citations or evidence to support this?
If you have seen this, please show us.
So we need to eat well to give our bodies the best chance at staying healthy. That makes sense, but things should we be eating?
The main translator of a healthy diet into a healthy immune system, in the human body is the gut microbiota. Keep it healthy! Take a lot of fibre, avoid refined sugars, refined carbohydrates and refined oils..
I don't know why this myth of fiber being good for you is still being propagated. Literally causes constipation, and you'll find that to be a common issue amongst vegans.
Did you provide processed animal fats to the rat or the grass fed animal fat, because that has huge effect depending on the source of animal fat
So which foods should I avoid then. All animal based fets meaning no butter no cheese? Does eating animal proteins is also bad? I guess i need to read the paper but there is no link in the show notes.
I found manz useful information on studies at the nutritionfacts youtube channel. Maybe that can help.
Just avoid refined sugar as much as possible and don’t smoke and you’ll be fine
People should remember they are omnivores and historically been that, it's recent era that is providing us with lots of processed food and ultimately damaging our body! Whole food is always a better option! Whether animal or plant source! Try to avoid processed animal fat and take grass fed one and it will be very much beneficial to your body!
Diversified diet is key, nobody knows all the facts. Our knowledge is always incomplete. That makes a diversified diet optimal.
Stock Portfolio has the same approach to deal with "risks".
Nice
I kinda follow Bulletproof Diet, and haven't had any cold or anything for a couple years now... No meat, but eggs, rice, popcorn, and lots and lots of butter for satiety (homemade ghee (boil until the milky goo coalesces, and remove it; eat the oil)), with intermittent fasting. Pizza or fast food on cheat weekends
👍👍👍
High fat diets are obesigenic? I thought it was because of sugar/carbonhydrate, not so much of fat?
@@gb7168 Thank for the clarification.
@G B As a med student (not an expert in the immunology), I don't know all the factors she might emphasize, but the following may apply. She mentioned that the source of fat was important, fat from animals are more likely to contribute to the development of cancer. Animal fat is high in omega-6-fatty acids and polyunsaturated fats. While Omega-6 fatty acids (not to be confused with omega-3 fatty acids that are found in fish and eggs), is useful and necessary in our diet, they have a tendency to be inflammatory. We have to be a little mindful of the ratio that we consume these in; for example the mediterranean diet (said to be very healthy), has both of these fats but they are present in a low omega-6:omega-3 ratio. Additionally, it has been shown that omega-6 tends to suppress cyclin D1 and the akt/mtor/nfkb pathway leading to the development of prostate cancer. Hope this helps.
@@aaro96live You got the direction right. But I guess more research needs to be done to examine the different types of Omega-6 fatty acids as there are different types of Omega-6 fatty acids, & there are also different types of Omega-3 fatty acids. The lady's description of her experiment is very vague, it would be better if Nature channel here provided a link for us to examine the experiment design & criteria of the paper. As plant based fats when in their natural forms eg. nuts etc., does not go bad quickly in the environment, these are usually consume in their natural unoxidized form & does not need to be subjected to human processing before being consume, unlike animal fats, & animal fats will have to be remove from a dead animal which upon death enters a state of decomposition & breaking down of their cells, oxidative degradation of the animal fats begin the moment we remove the fat cells from the animal bodies & they are exposed to the environment, & theres also the consideration of whether these animal fats were given raw or processed(eg.addition of nitrates as preservatives or heating, cooking, deep-frying etc. as such processes potentially create new carcinogenic compounds amongst the fats)& will likely affect the results since we are measuring carcinogenicity of different fat sources. What if we subject the plant based fats to the same processsing, cooking, grilling that the animal fats tend to be treated with before being consumed by humans, will it not cause such plant based fats to increase in carcinogenicity?
I think there is much space for improvement in the video. You can not define “fats” simply as the enemy. Avocados are full of fats, a good salmon is full of fats, and nuts are a source of fats. Especially when discussing a healthy diet, the differentiation of high monosaturated fats and the role of sugar is important to define.
My best wishes
@Daniel Good point, thanks
Yes, more people. That's exactly what this planet needs!
I'm going to be a vegetarian tonight
No más dietas obesogénicas!!
While this is an interesting addition to the way we look at the immune system, I feel like clarifying that eating 'healthy' is not a cure for illness. Genetics, environment and so many other factors play a part in why people get cancer. Vaccines help the immunesystem and lower the risk for fatal diseases.
And the unvarnished fact is that medical education provides utterly inadequate training on the surfeit of knowledge regarding best nutritional practices for preventing disease in the first place. Glad to hear that this investigator has come to the recognition that a plant-based, whole-food, high fiber diet actually provides the best opportunity for avoiding future ill health.
It seems odd to me that you say medical education is inadequate in regards to nutrition. Medical education generally covers nutrition quite thoroughly.
Because there are no best nutritional practices. Nutritional studies contradict each other all the time. Findings are often inconsistent and confounders are often not eliminated. Undoubtedly, there are healthier diets to choose from, though that being said, there is no single right answer. It varies from individual to individual, and hence the difficulty in choosing an ideal diet.
Nutrition is one of the fuzziest topics. There is no clear answer what to eat. A doc can only recommend evidence based science. 99% of recommendations in the www and RUclips have at best one tiny study behind but nothing with substance. Why? Cause those studies are more or less impossible. Therefore most studies are done with animals and I cannot recommend my patient a diet which was only tested for mice^^ The recommendations you wrote are basic knowledge. But to answer those questions more detailed is guessing.
But mice didn't evolve to eat animals.
You become what you eat
so what, you start developing leaves and chlorophyll if you eat a lot of vegetables?
What you eat becomes you.
