I’ve already mentioned a little about how stress can impact gut function. But did you know that what you eat can impact your mental wellbeing?
Your gut and brain are constantly communicating with each other, via what is known as the gut-brain axis.
Many studies have found a connection between mental health and diet, one of the most well known is the SMILES trial that published exciting results in 2017 showing that dietary changes improved depression symptoms. This is likely in part via the gut, as fibre and other components in food feed gut bacteria that produce substances involved in communication with the brain.
Diet and lifestyle alone aren’t a cure for depression, but they may be effective alongside traditional treatment options, and may lower the risk of developing some mental health disorders.
A Mediterranean-style diet in particular has consistently been associated with positive effects on mental health.
Some key foods that are thought to contribute to these effects:
◦ healthy fats (including omega-3 fatty acids) from foods such as avocado, nuts and seeds, extra virgin olive oil, or oily fish
◦ folate and iron from dark green leafy veg and animal food sources
◦ antioxidants and other phytochemicals from berries, cocoa and other plant foods
◦ fibre from plant foods including fruit, vegetables, legumes, whole grains, nuts, seeds, herbs and spices
Regular physical activity, eating with others (the social aspect of food), and enough sleep are also important.
