Diet rich in polyphenols can boost brain function and mood

Research shows that eating the right kinds of food can help address depression and improve brain function. In fact, some foods do this better than any medication.

What you need is to eat foods that are high in beneficial compounds called polyphenols.

Polyphenols are found in plant foods and can help reduce oxidative stress while improving “synaptic plasticity.” This can make you mentally sharper and even helps promote a good mood.

Chronic negative emotional states and poor brain function can result in more serious neurodegenerative diseases. Polyphenols can help address those issues.

According to a 2021 study published in the journal Moleculespolyphenols can help fight psychiatric disorders and improve cognitive performance. This means that eating the right kinds of food can help clear your mind and make you feel better.

A balanced diet is crucial for healthy brain function

Instead of taking medication linked to many negative side effects, take charge of your own health by eating the right foods. After all, healthy foods do more than just improve your physical health.

According to the 2021 study, polyphenols found in parsley exert anxiolytic and antidepressant effects. Several other studies have also shown that diets that are high in fruits and vegetables can improve brain function and mood significantly.

These nutritious foods can help you:

  • Feel calmer
  • Feel happier
  • Have more energy
  • Improve mental focus

Several case studies and anecdotal evidence have proven the many brain benefits of plant foods.

For example, people who want to treat depression naturally have found that following a balanced diet rich in the correct foods may offer many health benefits.


Additionally, eliminating known mood-affecting foods like gluten and artificial ingredients are linked to a significant increase in happiness and clarity of thought. (Related: Polyphenols in acai found to have a prebiotic effect that boosts digestive health.)

Polyphenols are good for your mental health

Scientists have been looking for a link between food and the mind for a long time since food’s effect on the body has long been known.

Michael Berk, a professor of Psychiatry at Deakin University in Australia, said the results of recent studies regarding food’s connection to mental health have consistently shown a definite link.

If you want to know how to support your mental health and have better clarity of mind, eat a nutritious diet rich in polyphenols. The more of this substance a food has, the more it will help boost your mental health.
