#2 Cayenne pepper
The powdered form of red hot chili pepper is often used to add a fiery flavor to boring, bland dishes, but its therapeutic benefits are equally recognized as well. Since thousands of years, societies of America and China have used cayenne pepper for treating flatulence and acidity. More recently, it has gained buzz for its cleansing and detoxifying properties. The primary bioactive substance in this spice is capsaicin, which is known to trigger fat oxidation and allow the body to use fat as fuel. Perfect for Mexican and Southwestern cuisines, it’s often sprinkled on eggs, fish and vegetable chili and practically any recipe that calls for normal ground pepper.
