A growing body of research is discovering that food doesn't just affect our waistline but also our moods, emotions, and even longer-term conditions like depression. Which makes sense, after all. Our brains are physical entities, running on the energy that we put into our bodies, affected by shifts in our hormones, blood sugar levels, and many other biological processes.Although there are many unanswered questions, the research to date can give us some guidance when we're hunting for an afternoon snack. What we know so far can be summed up, more or less, as this: Whole-food diets heavy on the fruits, vegetables, and unprocessed protein can lift our moods and protect us from depression, while too much junk food and sugar may put our mental health at risk.
