No, you don't because you cannot. You cannot, as an academic and as a researcher, make an unsupported claim, and then say you cannot be bothered to respond to respectful, logical, evidence based criticism of said claim at the first sign of disagreement. It is intellectually dishonest.
When you make a claim, such as "veganism cures eczema", the onus is on
you, the claimant to provide evidence. Asking for evidence is a perfect reasonable request, and rejecting the claim due to a failure to provide such evidence is a perfectly logical reaction.
Oh, so now you're adding ad hominem to your repertoire of logical fallacies. Awesome. Just to be clear, I did not say I "like the taste of meat", I said "I do love a good steak". Contrary to veganism beliefs, us omnivores are quite a varied bunch, and loving steak doesn't mean loving the taste of all meats. Let it be clear too that now you're also saying that just because someone loves eating good steak (or the taste of all meat), one has confirmation bias. Also let it be clear that I'm not supporting any lifestyle, I'm just questioning the rationale of a diet that excludes whole food groups that has not been shown to be harmful, and is in fact beneficial, to human health.
Actually, humans have thrived on an omnivorous diet for a very, very long time. If humans had stuck with veganism, you and I would not be debating about this right now because humans would have been wiped out a long, long time ago before Vitamin B12 supplementation/fortification was a thing.
Hold on. Last I checked you're not promoting a
plant based diet. You're promoting
veganism, which is the elimination of
all non-plant based foods. A plant based diet and veganism is quite different. Omnivores like me can be on a plant-based diet, and be very healthy indeed! I assure you that while I do love a good steak, I also do love a good kale and spinach salad, or stir fried kailan, or sambal kangkong!
So based on your belief, are you saying
ALL top institutions promote
veganism? If so, I urge you again to back up this claim with evidence
Wow. Have you heard of this person called Steve Jobs? I believe he was largely a vegan (definitely "plant-based"). Guess what he died of?

I'm not so much dismissing the
person. I'm just looking at the evidence/research presented and find
that lacking. However, now that you've mentioned it, I did do a bit of digging up on this "Physican's Committee" that he's the head of.
From
Wikipedia of Neal Barnard - In the 1990s, Quackwatch included Barnard in its list of "Promoters of Questionable Methods and/or Advice."
From
Wikipedia of PCRM - The Physicians Committee for Responsible Medicine (PCRM) is a non-profit research and
advocacy organization based in Washington, D.C., which
promotes a vegan plant-based diet, preventive medicine, alternatives to animal research, and encourages what it describes as "higher standards of ethics and effectiveness in research."[1] Its primary activities include outreach and education about nutrition and compassionate choices to healthcare professionals and the public; ending the use of animals in medical school curricula; and advocating for legislative changes on the local and national levels.
The
National Council Against Health Fraud has criticized PCRM as being "a propaganda machine" and the
American Medical Association has called PCRM a "pseudo-physicians group" promoting possibly dangerous nutritional advice. The PCRM is an advocacy group, and hence, contrary to what you said earlier, they DO have an agenda - to promote veganism! Sorry, I think I'll listen to the NCHR and AMA before the PCRM.
Also look
here - "Less than 5 percent of PCRM’s members are physicians". They're also funded by PETA, so saying that "alot of meat and dairy industry and pharmaceutical companies fund" other studies is sorta hypocritical in light of this.
Anyway, apart from the "guru" and his organization, let me reiterate this point in case you have missed it. In fact, since I have a bit of time, let me highlight what's wrong with making the conclusion that a balanced diet consisting of meat and other foods is bad for health based on the 100 studies you included. I'm only going to critique the first few, but making the argument based on the rest of the studies suffer from the same problem.
Studies 1-2 measure specific compounds within the human body, and have nothing to do with the argument. In particular, study 2 mentions advanced glycation end products (AGEs) as gerontotoxins, present in meat, and exacerbated by high heat cooking/charred food. This is not in question. However, the overall effect of this in terms of the difference it makes in human mortality seems to be negligible at best. It is also worth noting that while plant based foods themselves may have less inherent AGEs, vegetarian/vegan diets have actually been shown to cause
more of an increase in plasma AGEs than omnivorous diets. (
Source 1 and
source 2). So, it's not always as simple as to say that because certain foods have more/less of compound x, they will cause more/less of an increase of compound x in the body. The interactions of foods with other foods, and the body, is complicated.
Study 3-4 mentions
arachidonic acid which is actually a conditionally essential fatty acid that your body needs to function properly. It's also an omega-6 fatty acid, overconsumption of which causes inflammation. It doesn't mean eating meat will cause excessive inflammation, because many plant-based foods are high in omega-6 fatty acids as well, such as canola oil. Also, interesting, algae, one of the only food sources of Vitamin B12 for vegans, and also what you promoted eating, is also the richest plant source of arachidonic acid. Oops. If you have any nutrition/research background you should know this.
Studies 5-6 mention high fat animal meals. You actually didn't link to study 6, but study 5 is an acute study which has very little relevance to the long term well-being of a person. Case in point, if you measured markers of health immediately after a person exercises, you'd probably conclude that he is worse off than right before he exercised. The acute effects of exercise to the human body isn't good - muscles are broken down, there're high levels of catabolic hormones, indicating high stress levels. Does that mean exercise therefore is
bad?
Studies 7-9 were all linked to the same, wrong/irrelevant study "The capacity of foodstuffs to induce innate immune activation of human monocytes in vitro is dependent on food content of stimulants of Toll-like receptors 2 and 4". Again, this is a "transient" effect, and has little bearing on long term effects.
Study 10 also measures an acute response, and uses a meat-only diet, which is not what I'm advocating. It also suggests all inflammation is bad. This is not the case. Also, as I've said above, many plant-based foods trigger inflammation as well.
Study 11 is an observational study that studies animal fat. It cannot prove causation, It's also no surprise that people who eat diets high in saturated fats also tend to eat other unhealthful foods, and have generally less healthy lifestyles.
Study 12 - another study that only measures correlation, not causation. It cannot be used to "prove" anything.
Study 13 shows bad farming practices in the meat industry. Bad farming practices are bad, and should be avoided whenever possible, but let's not pretend that such bad farming practices are only prevalent in the meat industry. If you're read about
exploding watermelons or EWG's
dirty dozen, you'd know the problem exists both sides of the fence.
Study 14 - another study on a single compound (cholesterol) on a multi-variable problem that can establish no causal link.
People are not objective. Data is. People are charismatic. People have agendas. There have been many people who are highly educated and have great credentials in their chosen fields, many of whom are charismatic and are able to present their points and convince people, but they have also been shown to be wrong. Case in point - Robert Lustig, who seems to be convinced that fructose is the 1 evil ingredient that causes obesity and a multitude of illnesses. He has not been able to support his view in an online debate with Alan Aragon. I tend to be wary of people who make extreme claims that eliminating 1 "evil" ingredient/food type, or eating 1 "magic" ingredient/food type, will lead to significantly better health. The human body sadly doesn't work like that, and they usually have agendas to push.
Good! I love researchers! We need more people who bring research work and apply them to real world athletes. I wish you all the best! However, I would urge you to not fall into the trap of "magical" diets and "evil" foods. Stay in school, learn more, read more widely. Remember, eat too much vegetables, and you will STILL be obese. Drink too much water, and you will STILL die. Everything is dose dependent, and nothing works in isolation. Meat is not evil in the context of a balanced diet, and veganism doesn't cure cancer.
Let me make my points really clear then:
1. A balanced diet consisting of meat and non-meat foods does not cause detrimental health effects, and in fact supports an active, healthy lifestyle.
2. There is no evidence that a vegan diet is nutritionally superior to an omnivorous diet. Both have strengths and weaknesses, and both can be improved. The amount which you can improve a vegan diet however, is limited due to the elimination of all non-plant based foods.
Source - "Overall the cohort had a mortality about half that of the general population." However, there was no survival difference between vegetarians or omnivores. Nor was there any difference in rates of heart disease or stroke between the two groups.
3. Veganism is not sustainable without supplementation/fortified foods. It is fallacious to suggest that humans can thrive with a diet that
requires supplementation/fortified foods because it means evolution has somehow gotten something wrong.
4. Plant-based diets are great! However, veganism does not cure cancer/eczema/etc. I shouldn't even have to provide evidence since you're making the case, but I present you with these direct evidence anyway:
#1 - "Several CAMs used for other purposes were
associated with increased eczema prevalence, including herbal therapy (survey logistic regression; adjusted odds ratio [95% confidence interval], 2.07 [1.40-3.06]), vitamins (1.45 [1.21-1.74]), homeopathic therapy (2.94 [1.43-6.00]), movement techniques (3.66 [1.62-8.30]), and
diet (2.24 [1.10-4.58]), particularly vegan diet (2.53 [1.17-5.51]). In conclusion, multiple CAMs are commonly used for the treatment of eczema in US children. However,
some CAMs may actually be harmful to the skin and be associated with higher eczema prevalence in the United States."
#2 - "
During the vegan diet, both signs and symptoms returned in most patients, with the exception of some patients with psoriasis who experienced an improvement."
Plant based diets are great! They're just not the same as veganism, and they also don't cure cancer/eczema/etc.
Vegetables are truly awesome! Just remember to add some meat in that too and they'll be even more awesome!
I also have no idea why you're providing a video by a PhD student (not evidence, but just a 1 sided monologue supporting a plant based diet), and a press release of a research study showing a "link" (i.e. not causal) of a plant based diet to reduced risk in diabetes. I believe this thread is talking about eczema.
