For many years, people have had their own beliefs about certain foods from chicken soup being a cure for a cold, to ginger ale settling an upset stomach. These days, thanks to research, we know much more about the power of foods and how they can aid in promoting a healthy body. Here are three unexpected power foods that have great nutritional qualities.

1. Peanut Butter. Good news for kids and parents, that peanut butter and jelly sandwich you have been throwing together for the last few years is actually a healthy choice. Peanut butter not only tastes great but it actually is quite effective in combating heart disease as well as diabetes. Research has shown that women who ate peanut butter or other nuts consistently had a much lower risk for diabetes-around 21% lower. The good fats that peanut butter contains aid in stabilizing glucose levels in the body and also protect the most important organ in your body-your heart.

2. Chili Peppers. The spiciness in chili peppers is called capsaicin. It not only packs a lot of punch flavor wise, but is a great way to boost metabolism and increase fat burning naturally. Furthermore, those that add a little spice to their meals typically consume fewer calories overall. Capsaicin also relieves sinus congestion and is a great addition to meals when you are stuffed up.

3. Watermelon. Watermelon is not only mostly water, meaning it has minimal calories, but it is exceptionally great for fighting prostate cancer. One ounce of this juicy fruit contains 40% more lycopene than tomatoes, which have a great rep for aiding in prostate health. Lycopene is a powerful cancer fighting compound and also cleans the arteries of built up plaque, helping out the heart as well.

By eating these power foods along with a diet inclusive of many fruits and vegetables, taking a daily multivitamin, maintaining a regular exercise schedule, and getting a full eight hours of sleep each night, you will be on your way to feeling energized and healthy.
