Unfortunately, it’s not just a figment of the imagination, if you feel tired and sad in the dark winter months. In fact, according to studies, more than 5% of Americans experience seasonal depression due to the lack of light and thus a serotonin deficiency in the brain. An unhealthy diet, especially one filled with processed foods can promote depression. But this need not be accepted as a fate. There are some foods that are good for our mind – and chocolate is not the only one.
Fish with their high-quality omega-3 fatty acids and walnuts, for example, can promote mental wellness. Avocado, figs, sunflower seeds, cheese, etc. support the formation of serotonin (the happiness hormone). Green vegetables such as spinach, chard, kale, parsley, but also bananas contain plenty of the anti-stress mineral magnesium, which can have a positive effect on mood swings.
