Vegetarianism Harms the Brain?


Vegetarianism Harms the BrainAccording to a half-year long study conducted by scientists from Oxford University, perceived health benefits of vegetarianism might eventually turn into health problems. Eating solely vegetarian food leads to decrease in the brain volume as we age, so the scientists warn against excluding fish and meat from diet.

Why We Need to Eat Meet

Oxford scientists say that the lack of such foods as meat (especially liver), milk and fish causes essential nutrients deficiencies. Researches emphasized on vitamin B12 that is found in the food of animal origin. B12 deficiency causes anemia and central nervous system disorders. Yeast extract in some vegetarian dishes may partially supplement B12 deficiency.

Vegetarianism and Brain Health

The scientists discovered the fact after they observed over 100 of patients aged between 16 and 87 years. According to them, the changes were especially evident among the age group of 61-87 years. They focused their research on this group. Researches say they even observed some patients over five years. The results showed decreased brain activity and memory impairment. Besides, tomograms revealed the decreases in brain volume.

The scientists firmly claim vegetarianism has negative effects on the brain activity and, in some extreme cases, may trigger brain dysfunctions.

Brain Health and Drinking Alcohol

Additionally, the scientists analyzed the brain of beer lovers and people who prefer wine. It turned out that drinking beer is safer for the brain. Wine lovers’ hypothalamus (brain zone responsible for memory) was on average 10% less in size compared to that of barley beverage drinkers.


  1. I like animals but I will never be able to stop eating meat. Not because I’m afraid of brain dysfunctions but it’s so yummy, a beafsteak of baked chicken.

  2. I don’t agree. There are a number of vegetarians who are still active well into old age. Meat causes coronory disease, so it doesn’t matter if brain volume doesn’t decrease with age… meat-eaters don’t see that age!


  3. All the people I know who are vegetarians or vegans (I call them vegetables) are loony to begin with – maybe they are predisposed to be more loony.

  4. This is garbage & I think the author should be kicked a couple of times. Many famous geniuses in history (including albert einstein, walt witman, etc) were vegetarians. There is no evidence that directly correlates a vegetarian diet with a shrinkage of brain size that decreases intelligence/memory in humans. It’s the same fear tactic used by people who claim drinking a beer leads to the death of millions of neurons. Yet, there are so many high level professional that drink responsibly (should they be brain dead in comparison with the non drinking folk?). Come on, I would like to see the statistical power of these studies, the funding, and the actual authors. How could you possibly infer something as ridiculous as ‘wine shrinks the hypothalamus more then beer’ or that ‘vegetarians have no memory’. I would like to see your facts.

  5. They forgot to mention the existence of multivitamins, which can contain all the B12 you need.
