CSNN National Page > Good Foods for Your Mood: How Nutrition Impacts Mental Health

Eat these foods more often to enjoy a better mood, say scientists. Your nutrition impacts your mental health more than previously understood. Scientific evidence shows how to eat to improve your mood, and potentially beat anxiety and depression. Yet, certain foods harm mental health.

9 Best Foods to Help Your Mental Health

  • Dark Chocolate
  • Mushrooms
  • Leafy Greens
  • Apples
  • Berries
  • Grapes
  • Kale
  • Tea Leaves
  • Salmon/Sardines

What to Eat for Happiness

Chocolate is a popular mood booster. Here’s how it works: the cocoa flavanols in dark chocolate trigger more neurotransmitters (dopamine and serotonin) to be produced in the brain.  When there are more of these neurotransmitters in your brain, your mood increases. The same applies to tryptophan, found in mushrooms.

Does Food Affect Your Mental Health?

Perhaps you tend to reach for ice cream in moments of sorrow. Trade that tub of ice cream for a fruit or vegetables suggests science. According to researchers, your happiness is just one more fruit or vegetable away. After surveying over 12,000 Australians, researchers discovered that for every extra portion of fruit and vegetable an adult ate each day, their happiness increased exponentially. Populations who eat a lot of plants (vegetarians) are proven to enjoy a healthier mood. Sadly, among those who eat fewer fruits and vegetables, evidence shows a high occurrence of depressive symptoms.

How Does Nutrition Impact Mental Health?

Some of the best fruits to eat to be happier, include apples, berries, and grapes. Many people suffering from depression have high levels of MAO enzymes, and this enzyme can be blocked by quercetin found in these fruits. How does eating this food make you happier? By blocking MAO enzymes from breaking down neurotransmitters that make you happy, you get to enjoy a better mood. Kale and tea are other good sources of quercetin.

The Best Brain Food You’re Not Eating Enough Of

Omega-3 fatty acids found in algae, seaweed, and fatty fish (salmon, tuna, mackerel, sardines, anchovies) are integral to the brain and nervous system. These essential fats regulate which neurotransmitters are being made, and impact signal pathways in the brain and nervous tissue development. As such, it’s no surprise evidence shows a lack of omega-3 fatty acids is common in those struggling with mood-related illnesses, and eating omega-3 containing foods can boost your mood. Yet, most Canadians do not eat enough omega-3 fatty acids, particularly among high-risk populations, such as pregnant women and the elderly. Research from McMaster University reporting long-term care residents had lower omega-3 intake levels that what is estimated to prevent age-related diseases.

What Foods Make Mental Health Worse?

Some of the most common foods we eat in the Western diet have been linked with a higher risk of depression by scientists.

  • Processed/refined foods
  • Sugary beverages
  • Fried foods
  • Processed meat
  • Refined grain
  • High-fat dairy
  • Pastries/Biscuits

What You Eat Can Actually Improve Your Mental Health

Evidence supports that healthy foods such as olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy, and unprocessed meat have been linked with lowering the risk of depression. Eating these healthy foods may even improve depressive symptoms.

However, it’s important to clarify that eating healthy is not about perfection. Having good eating habits is about making efforts to nourish yourself with the majority of the mouthfuls you take – not every mouthful. All or nothing mentalities about food can lead to frustration, sadness, and  disordered eating. Success is the movement towards a healthier lifestyle; not perfection. Holistic nutrition is not a “diet” – but a healthy lifestyle that fits into your life and goals, and that incorporates your whole person (body, mind, and spirit).
