I found an interesting article in an issue of Nutrition Action Healthletter. These are some foods you should eat.
Sweet potatoes are loaded with vitamin A, C, carotenoids, and fiber.
Whole grain bread has about a dozen vitamins and minerals.
Broccoli has lots of vitamin C, carotenoids, and folic acid.
Strawberries have vitamin C, fiber and taste really good.
Beans are inexpensive, rich in protein, iron, B vitamins, folic acid, fiber, and low in fat.
Skim or 1% milk is a great source of calcium, vitamins, and protein. It also contains little or no artery clogging fat and cholesterol.
Cantaloupe is just like strawberries, great tasting, and just 1/4 a melon gives you as much Vitamin A and C as you need per day.
Spinach and kale are what most kids don't like, but they are loaded with calcium, carotenoids, folic acid, and Vitamin C.
Oranges are also great tasting and they are rich in Vitamin C, folic acid, and fiber.
Plain, old-fashioned, whole grain oatmeal is inexpensive and has no sugar or fat.
