4 Trusty StaplesYogurt
Research shows that one cup of yogurt a day may work to keep the gastrointestinal tract healthier, which can help ward off flu. Plus, recent studies show that regular consumption of dairy products like low-fat yogurt may help you lose weight. Look for yogurt that contains the active culture L. acidophilus, which is helpful in fighting off yeast infections. And be sure your yogurt's label says it contains live cultures, as the cultures are what have the positive effect on your GI tract.

An American staple and one of the cheapest sources of vitamin C, potatoes can round out any meal with high amounts of potassium and fiber, too. The skin contains the most fiber and the flesh just under the skin contains the most vitamin C. It's important to use fresh potatoes, as they contain more vitamin C than potatoes that have been sitting around in your cabinets. Also, be aware that soaking potatoes in water causes them to lose their vitamin C.
