Polyphenols from fruit, veg and chocolate help
Links between depression and disease are well established in adults. Depression is often observed in people with vascular diseases, such as high blood pressure, circulatory disorders and heart disease. This study looked at the effects of polyphenols on mental health status in 99 adults aged 40-65 with mild high blood pressure. Polyphenols are health-promoting compounds found in fruit, vegetables, tea, coffee, red wine, fruit juice, seeds, nuts and dark chocolate. Results showed those who ate six portions of fruit and veg (including berries) and some dark chocolate every day for eight weeks had fewer depressive symptoms and better general mental and physical health compared to those who ate two or less portions of fruit and veg and no chocolate.
