Western societies notice an increasing interest in plant-based eating patterns such as vegetarian and vegan, yet potential effects on the body and brain are a matter of debate. Therefore, we systematically reviewed existing human interventional studies on putative effects of a plant-based diet on the metabolism and cognition, and what is known about the underlying mechanisms. In addition, little is known, based on interventional studies about cognitive effects linked to plant-based diets. In sum, the increasing interest for plant-based diets raises the opportunity for developing novel preventive and therapeutic strategies against obesity, eating disorders and related comorbidities. Still, putative effects of plant-based diets on brain health and cognitive functions as well as the underlying mechanisms remain largely unexplored and new studies need to address these questions. Western societies notice an increasing interest in plant-based eating patterns such as avoiding meat or fish or fully excluding animal products vegetarian or vegan, see Fig. In , around 0. Likewise, the number of scientific publications on PubMed Fig. This increasing awareness calls for a better scientific understanding of how plant-based diets affect human health, in particular with regard to potentially relevant effects on mental health and cognitive functions.
Vegan, S. Hunt JR. Abstract Western societies notice an increasing interest in plant-based long patterns such as vegetarian and vegan, yet potential effects on the body and brain are a matter of health. However, a diet rich health fruit and vegetables that is typical of a vegan diet has a positive effect on the calcium economy and markers of term metabolism in men and women Finally, we should encourage performance-driven measurable outcomes, which may diet.

Effect of a brown rice based vegan diet and conventional diabetic diet on glycemic control of patients with type 2 diabetes: a week randomized clinical trial. Fish and olive oil are encouraged. As long as the calcium and vitamin D intake of vegans is adequate, their bone health is probably not an issue because their diet contains an ample supply of other protective factors for bone health.
