Okay, so the bronze goes to hormonal genital meat malformation. The silver goes to a study on IQ and vegetarianism. First, let me share a little background. We've known for nearly 30 years that vegetarian children test smarter than omnivorous kids. First shown in a 1980 study by Tufts University, the IQ of vegetarian children was found to be about 16 points above average. And their "mental age" was a year ahead of the rest of their classmates. Of all the veg kids, the vegan kids appeared the smartest. The pediatricians and psychologists knew the veg kids were bright, but the researchers noted that they were puzzled that they were so much superior.

Which came first, though? The chicken or the egg? Well, for the vegan kids, neither, perhaps. But were they smart because they were vegetarians, and therefore getting all that good nutrition—or did they become vegetarian because they were so smart? Well, the mystery has finally been solved—I guess. Those fantastic Brits followed 8,000 kids for 30 years. Measured their IQ at age 10, then came back 20 years later and asked which of them had become vegetarian during that time. Their findings? Higher scores for IQ in childhood are associated with an increased likelihood of being a vegetarian as an adult. Smart people evidently eat vegetarian. They even quote Benjamin Franklin saying vegetarian diets result in "greater clearness of head and quicker comprehension."

To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video. This is just an approximation of the audio contributed by veganmontreal.

  1. Why do you think the vegans in the British study had the lowest IQs? This is the opposite of what happened in the other study. Do you have a link to the full 1980 study?

    1. @Turing: From what I’ve seen, vegan kids are amazingly intelligent. The 1970 British study you refer to only had 9 vegans in it among thousands of people, which makes any results regarding veganism utterly meaningless. A mild caution in your chosen study states, “this estimate must be viewed with caution as only nine participants were vegan.” It’s always that way with these studies that supposedly spell disaster for vegans, it always turns out that the number of vegans in them was close to zero. Hmm, makes one wonder. If you believe that adding cow’s milk and bird eggs to a vegan diet ups anyone’s IQ, then what can I say to you? Anyhow, since your comment’s 3 years old, I’m posting this for others, not necessarily to you.

  2. I am raising my daughter vegetarian, mostly vegan. She was doing sign language by 3 months, and could speak before she was 1. She has absolutely no issues in school, and at 8, is reading at a 6th grade level. She also understands words up to 12th grade level. Though I don’t know whether intelligence causes vegetarianism or vice versa, the diet and lifestyle really works for us, and it helps us stay healthy and take care of our planet too!

  3. My question is this: does this necessarily indicate anything? Vegetarians & vegans in generally are MUCH more health conscious than those eating meat, who may also include many processed foods. So, perhaps the real question is they are doing better because of other junk foods that they leave out? I don’t think this conclusively proves evidence against.

    1. This was my question too. To be veggie requires a considerable amount of effort, escaping from peer pressure, habit etc etc, all things that you need intelligence for. and when you then find a partner they are likely to be in similar (intelligence) circles so your kids are gunna b samrt.

      1. Great points! I think Dr. Greger is just reporting the studies, which can all be found in our “sources cited” section. Perhaps the researchers discuss these points in their papers.

    2. Being vegan does not equate to being a healthy eater. Any plant-based doctor (Including Dr. Gregor) will tell you that. Eating potato chips and Oreos makes you vegan, but not healthy. And in the same respects, eating non-vegan does not automatically make you a junk food eater.

      1. False, Dr. Greger has a few studies that answered that question already and it looks like vegan junk eating couch potatoes do better than meat eating marathon runners.

        Look for these on his YouTube channel

        1. Arteries of vegans vs runners
        2. Is it diet, the exercise or both
        3. Diet vs. Exercise for weight loss

        1. He’s talking about whole plant food eaters. He has stated many times that oil clogs arteries like animal products. And eating junk food it obviously void of many nutrients.

  4. Couldn’t find a link to the article” Mental age and I.Q. of predominantly vegetarian children.” Could you provide a link to this article, please?

  5. On average, vegans had a childhood IQ score that was nearly 10 points lower than other vegetarians: mean (SD) IQ score 95.1 (14.8) in vegans compared with 104.8 (14.1) in other vegetarians (P=0.04)
