A plant-based diet is not necessarily a vegetarian diet. A meta-analysis on 24 studies proposes that although serum ferritin levels were lower in vegetarians on average, it is recommended to sustain an optimal ferritin level neither too low nor too high, calling for well-monitored supplementation strategies So what is the most compelling, evidenced-based research that supports plant-based eating? A study found that the climate change mitigation effects of shifting worldwide food production and consumption to plant-based diets, which are mainly composed of foods that require only a small fraction of the land and CO 2 emissions required for meat and dairy, could offset CO 2 emissions equal to those of past 9 to 16 years of fossil fuel emissions in nations that they grouped into 4 types. Additionally, participants with diabetes and prediabetes who had eating patterns that included more plant-based proteins or fish and less red meat were shown to have to lower insulin resistance and lower blood glucose A1C. Results: Participants in the vegan group lost an average of 7. 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.
People choose a vegetarian or vegan diet for a number of reasons. Research over many years has linked plant-based diets to lower rates of heart disease, type 2 diabetes, and some cancers as compared with diets high in meat and other animal products. Dietary guidelines and recommendations from nutrition experts reflect this, encouraging the adoption of diets such as the Mediterranean diet and the DASH diet that are heavy on fruits and vegetables and restrict consumption of red meat. Plant-based diets carry some risk of inadequate protein, vitamin, and mineral intake.

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.
