Research findings are clear: We feel better not just physically, but also emotionally and mentally, when we exercise (read these articles from the American Psychological Association and Harvard Medical School to understand the science behind the claim).
But what we eat may also play a role. Specifically, certain foods can be helpful for enhancing our mood (here’s the rough guide). Here’s what the research says:
It’s official. Dark chocolate is good for you. This is not just because it’s been reported widely in the media (e.g., CNN, Science Illustrated, Psypost). But it’s because a 2013 random controlled double-blind study showed that healthy adults given a daily high dose of cocoa polyphenols reported better mood at the end of the month than their peers who were given a placebo.
2. Oats and barley
Apart from the wholegrain benefits of eating complex carbohydrates, oats and barley are also good sources of folate, which is important for producing neurotransmitters which in turn control mood.
3. Lentils and beans
Lentils and beans provide not only dietary fibre and a low-GI (glycaemic index) complex carbohydrate meal option, they are also good sources of folate. This means pinto, borlotti, cannellini, and black beans, as well as chickpeas. Even mung beans are rich in folate (good ol’ tau suan).
4. Leafy greens and avocado
Folate, B6, and B12, are important for the production of neurotransmitters (e.g., serotonin) involved in mood regulation. Mangoes, avocado, and asparagus are also good sources of folate. B6 is naturally found in dark leafy greens, papaya, and orange, while eggs, cheese, and fish are good sources of B12. So Popeye was right after all: Spinach is good for you.
5. Tofu, flax seeds, and walnuts
Omega-3 fatty acids are reported to directly affect serotonin regulation (here’s the scientific explanation) and are found to affect mood. Other studies indicate incorporating omega-3 rich foods into one’s diet (typically oily fish such as salmon, mackerel, sardines) has a positive effect on mental wellbeing. Flax seeds, walnuts, tofu, and scallops are excellent sources of this highly sought after fatty acid.
