Reports that the BBC's chronic vegetarianism has made IQ lower have been called into question.

Original title: The BBC's long history of vegetarianism making IQ lower has been called into question
A recent report on the BBC website sparked protests from "vegetarians" and widespread discussion among microbiologists. The paper argues that vegetarianism lacks the many important nutrients the brain needs, and that long-term veganism undoubtedly affects people's intelligence. But microbiologists dismissed the report as based on outdated research that was irresponsible and dangerous to mislead the public.
"vegetarianism" is one of the fastest-growing trends in the new millennium. Statistics show that there are now about 375 million vegetarians worldwide, according to the BBC article. The number of "vegetarians" in the United States increased sixfold between 2014 and 2017, while the mainstream diet in India has been vegetarian since the 6th century BC.
BBC report traces our ancestors to the idea that eating meat makes us human or smarter, and asks whether the "defects" in the diet of veganism "affect the ability of vegans to think"? Long-term vegan brain health has long been a problem in health research because it says vegetarianism is difficult to artificially add nutrients to. While some vegetarians may take nutritional supplements, experts say that in practice, it is not possible to expect everyone to consume nutritional supplements scientifically and reasonably.
, Oxford University biologist Nathan Covernas says the recent shift in plant-replacement diets is worrying. "Vegetarianism can lead to b12 and iron deficiency, which will no doubt affect your intelligence, " he says. "
report not only upsets "vegetarians", but also sparks discussion among microbiologists. Scholars have published different opinions that their views are based on outdated research, contradicted by a new study published in the British journal Nature, which argues that a higher-quality diet, including meat, has improved through cooking, coupled with walking upright, contributing to the growth of the brain's volume. In other words, primitive humans did not become smart by eating meat, but rather by changing the way they live, which promoted the growth of the brain. In addition, the lack of B12 is not just a vegetarian problem, but the current general lack of B12 in the entire human population.
