What is the best diet for mental health?

Experts have increasingly studied the effects of diet on mental health. Many of them have noticed that those who follow a standard Western diet, which includes highly processed foods and added sugars, are at higher risk of developing anxiety and depression.

Can Diet Help Mental Health?

Nutritional psychiatry, which some call psychonutrition, is a new field of study that focuses on the effect of diet on mental health. Therefore, an article in the journal Nutrition Society reviewed the body of existing analyzes on a diet, nutrition, and mental health.

Therefore, research suggests that the more a person follows a Western diet, with its highly processed foods, the greater the risk of depression and anxiety.

Researchers at the King’s College Institute of Psychiatry in London, UK, have investigated exactly how nutrition can affect mental health. As a result, they have focused their research on the effects of diet on the hippocampus.

The hippocampus is an area of ​​the brain that generates new neurons in a process called neurogenesis. Thus, the study linked neurogenesis in the hippocampus to a person’s mood and cognition.

Stressful experiences reduce neurogenesis in the hippocampus, while antidepressants appear to promote this process.

Food and factors that affect mental health

Factors that can negatively affect neurogenesis in adults include:

  • Aging;
  • Oxidative stress;
  • High-fat diets;
  • Excess sugar;
  • The alcohol;
  • Opiates

Foods and habits that improve mental health

Healthy food and habits appear to promote neurogenesis. These include:

  • Diets that include polyunsaturated fatty acids, curcumin, and polyphenols;
  • Foods that meet caloric needs without the person eating too much or too little;
  • Physical exercise.

So what is the best diet for mental health?

Among common diet plans, the Mediterranean diet has the strongest evidence that it supports the ability to reduce symptoms of depression and other mental health problems. It’s also a methodology that experts routinely recommend for general health and wellness.

Therefore, the compounds in the Mediterranean diet that are associated with lower rates of depression include:

  • Omega-3 fatty acids;
  • Vitamin D;
  • Methyl folate;
  • S-adenosilmetionina.
