A study conducted by Veganuary participants found that many reported improvements in their mental health after trying a vegan diet. Participants cited factors such as a sense of achievement, living according to their values, and experiencing physical health benefits from plant-based nutrition. The study also explored the impact of vegetarian and vegan diets on mental health, with conflicting research results. While unhealthy diets, regardless of preference, are more likely to be linked to depression, a healthy plant-based diet may actually be beneficial for mental health. Overall, the study highlights the potential positive impact of Veganuary on mental wellbeing and encourages further exploration of the link between vegan diets and mental health.
