In the study of 422 adults, those who consumed raw produce reported higher levels of psychological wellbeing than people who mostly ate cooked foods.

Cooking and canning produce “would most likely lead to a degradation in nutrients, thereby limiting their beneficial impact on mental health," the researchers say.
