Whole grain’s protective eﬀect against heart disease and diabetes is well-documented, and because these chronic conditions also relate to risk of brain health and mental health, researchers wanted to examine this relationship directly. In this study, scientists analyzed 23 studies on whole grain intake and risk of cognitive decline, depression, anxiety, and mood disorders and evaluated the strength of the evidence. They found that people who eat more whole grains are more likely to have better mood, depression, and anxiety scores. The evidence on whole grains and cognition was inconclusive, meaning that more research is needed.
