I think that eating healthy is important. I know my anxiety gets better when I feed my body with the right food. I eat unhealthy things too, candy in particular, but I always have in mind to eat vegetables and fruit. I eat processed food but I make salads to go with it. My anxiety needs to be fed the right food in order for me to cope. A strong body gives a stronger mind.
Speaking of healthy, I think bananas are great. They come in a package filled with good things. I don`t like to eat them the way they are but I put them in yoghurt and other things. They can sooth sore muscles because of the high levels of potassium. They are also the fruit with the highest level of carbs which make them great to eat both before and after workouts. They can lower a high blood preassure and the potassium can help with stress. I would never replace medicines with bananas but it`s good to know. The magnesium can sooth headaches.
Like I said I would never replace medicines with fruit but if eating it can help somewhat with illnesses everyone should eat more of it.
