According to his research, the best ways to avoid depression are to avoid anything that links to inflammation.
To avoid inflammation :
-
Exercice 30 minutes every single day
-
Eat a lot of vegetables, fruits, nuts, and mushrooms. Avoid inflammatory food such as processed meat or red meat.
-
Don’t smoke

An incomplete article if the studies exist and weren’t mentioned. A useless hypothesis if the guy is already authoring books but hasn’t done any studies yet.
