I noticed a couple comments already from people who tried a vegan diet for several years but had to quit. Feel free to comment your story here if you have one!

Fun fact: in Switzerland it is illegal to call anythig milk except whole milk. Not even skimmed milk qualifies as milk.

There was once a study done where children were allowed to choose whatever they wanted from a rather broad diet. They found unusual combinations like liver and orange juice for breakfast, and one child began to drink cod liver oil as a beverage. When they evaluated the actual nutrient value of what the children were eating, they discovered that the children were seeking foods that provided the exact nutrients they needed, and appeared to find the right foods mostly by taste.

Unfortunately, this probably wouldn't work now. The study was done in the 1930's, before the rise of synthetic flavorings allowed us to make anything taste like anything.

Regarding the jaw development, you missed a very important aspect. People need to use their teeth to chew tough foods to develop their jaws properly. So one of the big issues with processed food us that it is so soft.

[pleaserespond]

There's a reason they're called "supplements" and not "replacements". It really is astounding that humans can eat so many varied foods compared to other organisms.

I'm really surprised that while talking about narrowing palettes and the problems with teeth, you didn't mention that eating processed foods eliminates the chewing required for traditional unprocessed foods. Chewing is really important for proper facial development and nasal breathing, which can alleviate sleep apnea.

As for the cat study investigating raw meat vs cooked meat, it was eventually found that the cooking method reduced the taurine content in the meat, which was the cause of the observed health effects on the deformed cats. Nowadays either the taurine is added back to the meat as with commercial cat food, or it is cooked in a way where taurine doesn't leach out (taurine isn't destroyed by heat, but it is water soluble). Grilling or baking meat may preserve the taurine content versus boiling.

There is also a connection between issues with the dental arch, crooked teeth and having not been breastfed. Breastfeeding uses many more muscles in the mouth, jaw and face than bottle feeding. Breastfeeding appears to help the mouth, jaw and face develop properly. In many studies bottle feeding was correlated with issues with the development dental arch, crooked teeth, etc.

So in addition to highly processed food for older children and adults causing serious issues, highly processed food and "highly processed" feeding methods (using an easy to suck latex or silicone bottle nipple rather than a difficult, muscle developing breast to milk nutrients from) for infants may contribute to mouth and facial development.

(Yes, I am well aware *some women can't breastfeed* I'm an IBCLC (lactation consultant) but just because some aren't doing or can't do something doesn't mean that something isn't still the the most healthy thing.)

15 years vegan here, I have none of the issues described by the supposed prior vegans. I go to the doctor once a year for bloodwork and my levels are top of the charts healthy. It's almost as if those anecdotes have been cherrypicked to support a particular point of view. Hmmmm.

This video feels less a criticism of veganism and more so a criticism of overly processed foods

[douglasmagowan]

Something on my mind watching this is organ meat. We eat almost none of it compared to previous generations, and it is extremely nutrient dense.

I took double dose of pre-natal supplements during pregnancy (doctor's recommendation) but I still had too low levels of iron, thus anemia for almost a year. I had postpartum hemorrhage and had to take stronger iron supplements both for me and my baby for two months after birth.
The issue was probably that I had no money to afford a whole diet. I got pregnant unexpectedly during a financial crisis. While I ate iron- rich foods when I could, it wasn't enough and my diet probably lacked other nutrients. I also didn't get enough vitamin D and I was so exhausted all the time I only got out and exercised when I had to do the prenatal check up and exams.

Moral of the story, humans aren't supposed to live off supplementary pills.

No conversation about the sponsorship/funding of the studies quoted? Who’s paying for these various studies, and which corporations are benefiting?

[CARATMom]

You can do a video on just margarine alone as an example of the power of marketing. Because they really had us thinking a solid chemical oil dyed yellow was healthy

[kingbranden]

It's just so damn exhausting. No matter what diet you have there's always a thousand people pointing a finger at you telling you why you're going to die because of it.
There's so much conflicting information that it's hopeless to ever try to piece together any sort of meaningful understanding of it all.

I've been vegan for 7+ years and vegetarian for 20 and while I do take vitamin D supplements (because I live in the north and like to wear clothes) and I didn't have any issues other than my doctor said it was low, my B12 is fine. B12 is a tricky topic and the research is still coming in. B12 is a very complex vitamin and is destroyed in the the upper intestine but absorbed in the lower intestine. If taken as a supplement or eaten as part of ones diet, the amount of B12 that can be absorbed by one's lower intestine is limited by the amount of intrinsic factor their stomach is able to produce. Many bacteria have been found to produce B12 and vegans and vegetarians can get enough B12 from a health gut biome. Nutritional yeast is also in everything these days. Being vegan takes commitment, discipline, and an understand of nutrition or it won't work. Pottinger's cats shows another mechanism for malnutrition and shows that modern diets have had an effect on people's teeth among all sorts of other things. I think veganism is being blamed for the shortcomings of the people trying vegan diets and not the diets themselves.

I wonder what effect mass farming of animals in small enclosures to fatten them up has had on the healthiness of meat, assuming that animals farmed this way have more fat than wild animals

[ptimal]

One of my biggest eye openers in life was finally realizing first hand how i was supposed to feel. Happened when i cut out the junk and ate veggies fruits and meat only. I mean after 6 weeks i realized my whole being leveled up. Mental state, function, emotions, anxiety vanished, brain fired on all cylinders, i felt young and alive. I cant say enough about it. Dont eat junk. Society would be a better place if everyone did.

[TheOneAndOnlySame]

I just want to say that : nutrition science is a very approximate science . Their claims change constantly. It's because it is incredibly difficult to observe, analyse and understand the countless interactions in between dozens of organs and thousands of compounds: and their cross interactions etc
I take everything they say with a grain of salt or two, but not three

One of my aunt has been vegan since 2000's, She is aging gracefully for someone's whos almost 60 years old, she could look like she's well in her early 40's
