Scientists have looked at how our diet changes our mental health. What we eat affects our brain until we are 30. This explains why older adults are more emotionally stable. The lead researcher was a professor of health and wellness studies. She said people knew that diet affected diabetes, heart disease and obesity, but not that it affected our mental health. She suggested that mental well-being led to healthy eating and exercising.
The research was carried out anonymously. A survey was sent via professional and social networks. Researchers found that adults under 30 who ate fast food more than three times a week had higher levels of anxiety and depression. For adults over 30, eating less carbohydrates and more fruit reduced these conditions. The researchers said a Mediterranean diet was as good for our brain as for our body. It has things that are important for a healthy brain.
