Food for mental health: What’s good for your mind?
We look at the connection between nutrition and your brain and reveal five nutritious foods that can help boost your mental health.
Healthy diets, like those rich in whole foods, support many aspects of mental health including cognitive [brain] function, concentration, memory and mood regulation, as well as reducing the risk of depression and other mental disorders,” she says.
Many studies suggest a diet rich in fresh vegetables, fruits and fish is associated with a reduced risk of depression, while a diet with added sugar, soft drink and junk food can be associated with an increased risk.
Global trends show a major drop in the consumption of nutrient-dense foods, making the adoption of healthier eating habits all the more important. The good news: a few simple dietary changes could be enough to make a big difference to your mental health.
Food for mental health: Why is diet so important?
Eating a balanced diet rich in a variety of minimally processed whole foods gives the brain key nutrients like omega-3 fats, B vitamins and iron, and also helps the gut by boosting fibre levels. Healthy gut bacteria are important for immunity, as well as influencing your metabolism, weight and brain function – which means better mental health, too.
On the flip side, eating large amounts of nutrient-poor, processed foods that are high in fat and sugar may have a detrimental effect on brain health. This type of diet can negatively impact neurotrophins, important brain proteins that promote new brain cell growth and protect the brain against oxidative stress, which is an imbalance of free radicals and antioxidants in the body, leading to cell and tissue damage.
Processed foods are also low in fibre and contain food additives like artificial sweeteners and emulsifiers, which may alter gut microbiota and damage the intestinal barrier, leading to inflammation. That’s concerning, given there’s a strong connection between gut health and mental health. In fact, gut inflammation has been linked to anxiety and depression. Turns out many of the foods that are bad for physical health may be just as bad for your mental health.
Signs you may need more brain health-boosting foods
Some of the signs your diet might be lacking in important brain nutrients are:
fatigue and low energy
fluctuations in your mood
poor concentration
anxiety
depression
Some of the best foods for mental health
Salmon
Loaded with omega-3 fatty acids, salmon is one of the top-ranked foods for mental health.
“Omega-3 fatty acids have been found to reduce the risk of depression and dementia, and help improve mood,” she says. Their anti-inflammatory and antioxidant powers are thought to promote healthier brain cells and reduce brain deterioration related to ageing.
Eggs
Eggs are a nutritional powerhouse for your brain. Their B vitamins – B1, 2, 3, 6 and 12 – play an important part in regulating normal brain function, while the choline and lutein they contain are key for brain development, memory and learning. Choline can’t be made in the body in sufficient amounts so adding eggs to your diet is a great way to ensure you’re getting enough.
Nuts
Nuts are nature’s wonder pills – they can be enjoyed as a snack or added to most meals, and they’re loaded with mood-boosting nutrients.
Avocados
Beyond their national dish status, smashed avo’s contain a brain-loving bundle of nutrients including monounsaturated fats, niacin, folate, vitamin B5, C and E.
The brain needs B vitamins for healthy cell structure and the production of neurotransmitters, our nervous system’s messengers, while vitamin E is an antioxidant involved in protecting nerve cells. And monounsaturated fats are important for healthy blood flow, which is vital for maintaining a healthy brain.
Blueberries
Blueberries may help prevent age-related memory loss, and improve motor control and cognition. Blueberries have one of the highest antioxidant concentrations of any fruit, which helps reduce oxidative stress and inflammation, protecting brain cells from damage. They also change the way neurons in the brain communicate, helping the brain stay healthy.
