The Remarkable Link Between Diet & Mental Health

What should you eat if you want to boost your mood? Learn what to eat (and what not to eat) for improved mental wellbeing.

You may have heard of the “food-mood connection.” Research indicates that our diets greatly impact not only physical health, but mental wellbeing. Some foods seem to boost mood and reduce psychiatric symptoms while others are linked to depression and anxiety.

This article is about “mood thugs” and “mood champions.” Mood thugs are foods that can make you feel bad, while mood champions are foods that can give you a mental boost.


Mood Thugs

Sugar: Sugar consumption has been linked to depression, slows memory and learning, and reduces brain volume. Also, a recent study found that the concept of a “sugar rush” is myth. Sugar has virtually no impact on mood, regardless how much you consume. In fact, it can make you feel less alert and more tired.

Sugar is not the only villain; fat can be just as harmful. One study found that a high-fat diet may lead to symptoms of depression and anxiety. Furthermore, trans fat may lead to poor memory function.

Processed meats: If you have bipolar disorder, avoid processed meats such as jerky, hot dogs, etc. Researchers found that nitrates in processed meats are associated with mania.

Mood Champions

Vegetables: A diet high in fiber and vegetables (with limited added sugar) has been linked to improved mood and a reduction in depressive symptoms. Interestingly, women seem to benefit more than men, and the effect is even greater when exercise is added. A vegan or plant-based diet is associated with lower levels of depression, anxiety, and stress.

Raw produce: Fruits and vegetables are good for mood, but raw fruits and veggies are better. A raw diet is associated with higher levels of mental wellbeing and lower levels of psychiatric symptoms.

According to a recent study, the top raw foods associated with mental wellness are apples, bananas, berries, carrots, citrus fruits, cucumbers, grapefruit, kiwi, lettuce, and dark, leafy greens.

So how many servings of fruits and veggies should you eat per day for optimal mental health? At least 8, according to one study that found happiness benefits were evident for each portion for up to 8 servings per day.

Happiness nutrients: What nutrients should you include in your diet for improved mental health? Research indicates the following are important for mental wellbeing:

  • Omega-3 fatty acids (fish, flaxseed, walnuts)
  • Phospholipids (egg yolk, soybeans)
  • Niacin (liver, avocado, brown rice)
  • Folate (legumes, beets, broccoli)
  • Vitamin B6 (chickpeas, tuna)
  • Vitamin B12 (sardines, fortified nutritional yeast)

In sum, skip the fast food and soda; head to the salad bar instead to feed your mood and your belly!
