In general, healthy eating ingredients are found around the outer edges of most grocery stores, while the center aisles are filled with processed and packaged foods that aren’t good for you. Shop the perimeter of the store for most of your groceries (fresh fruits and vegetables, fish and poultry, whole grain breads and dairy products), add a few things from the freezer section (frozen fruits and vegetables), and visit the aisles for spices, oils, and whole grains (like rolled oats, brown rice, whole wheat pasta).
Dinner? That's miso soup with some chopped sea vegetables (like the Japanese nori, used to make sushi) snipped over top. Or you might choose a cup of brown rice with a few chopped vegetables mixed in. "Brown rice gives your body plenty of B vitamins, which is a stress reducer. It's very high fiber, will fill you up, will help you sleep, and will flush you out in the morning."
