Diet and Neuro-Mental Health

Increasing evidence shows that diet plays an important role in the development of mental disorders such as neuroses, psychoses, ADHD etc., and nuerological disorders such as Alzheimer’s disease, Parkinson’s disease, multiple sclerosis etc.

  • Diet and Obesity May be Linked to Alzheimer’s: A Swedish study that included 8,534 twins over the age of 65, has found that the risk of dementia was almost double in those who were overweight versus those of normal weight and those who were obese had almost a fourfold increase in risk.
