Food and Mental Health: The Impact of Nutrition on Emotional Well-being

Foods that Affect Mental Health

Welcome to my blog post on the fascinating relationship between food and mental health. In this article, I’ll explore the profound impact that nutrition has on our emotional well-being. The food we consume plays a crucial role in our mental health, affecting our mood, cognition, and overall emotional state. By understanding the connection between food and mental health, we can make informed choices that support our emotional well-being and promote optimal mental health. Join me as I delve into the impact of nutrition on emotional well-being and uncover the importance of nourishing our bodies and minds with the right foods.  

Protect Your Mental Health

There is one dietary pattern that is consistently linked to lower rates of depression. It’s also linked to lower rates of heart disease, diabetes, and certain cancers. That diet? The Mediterranean diet.

The Mediterranean diet is based on what people traditionally ate in that area of Europe. It’s rich in fruits, vegetables, olives and olive oil, whole grains, nuts, and lean proteins such as chicken or fish. It’s also low in red meat and dairy.

Research on Food and Mental Health

Eating a Mediterranean-style diet may do more than protect your mental health over the long run—it may even help to improve symptoms of depression after they’ve started. Exciting new research from the Food and Mood Centre at Deakin University in Australia recently tested this hypothesis in a clinical trial. 

The SMILES (Supporting the Modification of lifestyle in Lowered Emotional States) trial recruited participants with depression and randomly split them into two groups. One group (the “Diet” group) received a dietary intervention that included several meetings with a dietitian for education, support, and nutritional counseling. This group was given guidelines to eat a modified Mediterranean-style diet for 12 weeks. The other group (the “Befriending” group) had the same number of meetings as the “Diet group,” but instead of a dietitian and nutrition advice, they met with a neutral new “friend.”

After 12 weeks, the researchers compared each person’s symptoms to how they were feeling at the beginning of the trial. They also compared these two groups to each other. It turns out that the people who participated in the Diet group (the ones who changed their diet to be more like the Mediterranean diet) had a greater reduction in their depression symptoms than those in the Befriending group. Participants who improved their diet the most experienced the greatest mental health benefit. In fact, 32 percent of the people in the diet group went into remission, compared to 8 percent of those in the befriending group.

What does this all mean? Eating a Mediterranean-style diet reduces your risk for depression before you ever experience it. Plus, if you do experience symptoms of depression, changing your diet can help improve symptoms of depression after 12 weeks of a more Mediterranean-style diet. This is huge!

How Can Food Affect Your Mental Health?

Food is commonly referred to as “fuel,” but its impact on our physical and mental well-being goes far beyond mere energy provision. What and how we eat profoundly affects almost every aspect of our health. Beyond providing calories for bodily functions like movement, cognition, digestion, and respiration, food supplies essential vitamins and minerals that play a crucial role in complex reactions. These reactions are necessary for the production of vital compounds such as neurotransmitters, which serve as chemical messengers in our brains and facilitate communication between nerve cells. Additionally, certain dietary components like fiber and specific starches nourish the beneficial microbes residing in our gut, which possess their own nervous system, communicate with the brain, and even produce their own neurotransmitters. Also look to add in fermented foods to improve gut health.

  • Examples of fermented foods include plain yogurt, kefir, sauerkraut, pickles, miso, kimchi, etc.
  • When shopping, look for ones in the refrigerator section (not on the shelves at room temperature), as refrigerated ones are more likely to still contain live active cultures.

The Best Food for Your Mental Health

The twelve nutrients considered to have “antidepressant” roles in the body include:

Eating more foods that are rich in these nutrients can help your mental health.

How Neurotransmitters Affect Our Mental Health

Neurotransmitters play a critical role in regulating our moods, and one key neurotransmitter, serotonin, has been linked to poor moods and depression. Interestingly, many medications prescribed for depression aim to enhance serotonin levels. But what does all of this have to do with nutrition and food? Well, apart from the essential roles that nutrients play in serotonin production, there is a fascinating connection between the gut and serotonin. Surprisingly, recent evidence reveals that a staggering 90 percent of serotonin receptors are not located in the brain, but rather in the digestive system. This finding sheds light on why common side effects of antidepressant medications, such as nausea, diarrhea, or weight gain, are experienced in the gut. It emphasizes the crucial role that nutrition and the gut-brain axis play in influencing our mood and mental well-being.

How Inflammation is Connected to Our Mental Health

Inflammation is yet another connection between what we eat and our mental health. People with depression tend to have higher levels of inflammation. Those who eat a more anti-inflammatory plant-based diet and avoid sugary and processed foods have reduced inflammation and reduced risks for depression.

These examples illustrate the many complex interconnections between what we eat and how it can influence the way we feel (emotionally).

Final Thoughts

The connections between what you eat and how you feel keep getting stronger. New research has found that a Mediterranean-style diet can reduce your risk of developing depression and can even help to alleviate some symptoms of mild to moderate depression. This includes a focus on eating more whole grains, vegetables, and fruits, with some dairy, nuts, and olive oil every day. 

Benefits go beyond better moods and can also reduce your risks for heart disease, diabetes, and some cancers. 

If you are experiencing severe depression or other mental health issues, you may need additional help beyond food, so see your licensed healthcare provider.
