Nutrition and Mental Health

 

If you are taking the time to read this, you are probably well aware of the strong connection between the nutrition you get and your physical health. A healthy diet helps to protect against malnutrition in all its forms, as well as noncommunicable diseases, including diabetes, heart disease, stroke and cancer. In 2021, 20% of all deaths worldwide were associated with poor diet, about 11 million people. But what about our mental and emotional health?

In fact, nutrition plays a significant role in mental health, as the foods we eat can affect our mood and cognitive function. A healthy diet rich in fruits, vegetables, whole grains, and healthy fats can help reduce symptoms of depression and anxiety, while processed foods and sugars may contribute to mental health challenges. Earlier studies suggest what you might expect: eating junk isn’t great for your brain. People who consume plenty of fruit, vegetables, and fish seem to be less at risk of depression compared to those who favor fatty meats, processed carbs, and sweets. But new research suggests that the connection between diet and mental well-being is a little more nuanced than scientists once thought.

No single food has magical powers (The "superfood myth".) “We want to shift the conversation away from singular foods and diets and into talking about food categories,” says Drew Ramsey, an associate professor of psychiatry at Columbia University. His studies, for example, found that spinach, Swiss chard, kale, and lettuce contain the highest antidepressant nutrients per serving, but that it didn’t really matter which leafy green you ate—what matters is that leafy greens are a regular part of your food intake

Nutrition is just one piece of the mental-health puzzle, but it has researchers excited. “I really am a big fan of responsibly using medications and effective talk therapy to treat depression,” says Ramsey. “But focusing on diet allows us to empower patients to think about their mental health as tied to nutrition.”

Here is a deeper dive if you want to know more. If you just what the short version, here are the top three food categories for a healthy mental diet:

• Complex carbohydrates: Foods like brown rice and starchy vegetables provide energy. Quinoa, millet, beets, and sweet potatoes have more nutrients and keep you satisfied longer than sugary snacks.
  
  
• Lean proteins: These give you energy and help your body think and react quickly. Good sources include chicken, meat, fish, eggs, soybeans, nuts and seeds.
  
  
• Fatty acids: Essential for brain and nervous system function, you can find them in fish, meat, eggs, nuts and flaxseeds.
