Vegetarianism is dangerous for the brain.
Scientists from Oxford University after a six-month research came to the conclusion that vegetarianism might not be as useful as previously thought.
Thus, the use of only plant foods leads to loss of brain mass, and therefore completely exclude meat and fish experts do not suggest.
Oxford researchers say that in the absence of dietary products such as meat (especially liver), milk and fish leads to a lack in the body of some very important nutrients and vitamins. One of the most serious weaknesses researchers called the lack of vitamin B12 is of animal origin. The lack of this element leads to anemia and damage to the Central nervous system.
Part of the lack of this substance can be replenished by the yeast extract, which may be present in many vegetarian dishes.
To such conclusions the doctors came as a result of continuous monitoring more than a hundred patients in the age from 16 to 87 years. According to the scientists, especially the visible differences are visible among the age group 61-87 years. Here was conducted the main studies, the results of which were noted: a decrease in brain activity, memory impairment, in addition to tomograms were recorded reducing the weight and volume of the brain.
British experts note that some patients they observed over 5 years and can certainly say that the rejection of animal foods has negative effects on the brain, and in the most extreme cases leads to brain dysfunction.
In addition, scientists analyzed the brain of beer lovers and people who prefer wine. It turned out that beer does less damage to the brain. Thus, the hypothalamus (part of brain responsible for memory) was on average 10% smaller wine lovers, in comparison with lovers of barley beverage.
Another side effect, provoking a decrease in brain mass, leads to the violation of metabolism in the body and increased body mass index in 7 to 13%, according to Oxford.
