A plant-based diet, also known as a vegan, becomes more and more popular, especially among young people.

For some, it is a calling to, what they believe, to help the planet against global warming. For others, it is a solution to some health issues. Either way, we should respect an individual choice and celebrate the strength of the convictions of human beings. 

We are going to talk about the effects of the vegan diet on the body and brain. This is in no way a criticism of veganism and its impact on the human body.

Researchers in the referenced study pulled out hundreds of scientific studies to see if there were benefits or downsides of a vegan diet on the human body. This scientific approach is called a systemic review.

The results of this systemic review were alas inconclusive. 

Based on this systematic review of randomised clinical trials, there is overall robust support for the beneficial effects of a plant-based diet on metabolic measures in health and disease. 

However, the evidence for the cognitive and mental effects of a plant-based diet is still inconclusive. 

In other words, we do not know precisely how the vegan diet affects the human body. The safest approach is to accept that different people respond to a vegan diet differently from individual metabolic responses.  

A prudent practitioner and a health-conscious patient would take a common-sense approach and test the effects of a vegan diet on one’s health. The test is relatively cheap and very informative.
