Is veganism linked to mental illness?

The Mind Pump Podcast discusses the relationship between veganism and mental health. A meta-analysis involving over 160,000 participants found that vegetarians and vegans have a higher likelihood of taking medication for mental illness, considering suicide, and exhibiting behaviors related to poor psychological health such as depression and anxiety. The discussion explores whether this higher prevalence is due to the diet itself or if individuals with these mental health issues are more attracted to veganism, possibly as a form of control or expression of empathy, while also noting the potential for nutrient deficiencies in a strictly plant-based diet 1.

However, the podcast also presents a counterpoint that some meta-analyses and studies may be biased due to conflicts of interest, such as funding from meat industry affiliations. It's emphasized that there are also studies suggesting that plant-based diets can reduce depression and anxiety 2.

In summary, while there are studies suggesting higher rates of mental health issues among vegans and vegetarians, these findings are complicated by factors such as potential bias in research, individual reasons for choosing a vegan lifestyle, and the nutritional completeness of their diet.
