Diet
Here is a link to an article about foods and how diet affects mental wellness, especially in youth. It links certain foods and supplements to improvements in mental health conditions. There is also a link for the UK's Mental Health Foundation's podcast by Dr. David Peters about diet and mental wellness. As both indicate, these are resources to raise awareness, and a doctor should always be involved when making significant dietary changes.
