Supermarkets these days are filled with processed foods that are contributing to numerous health problems such as diabetes, high blood pressure, heart disease and probably many more. An easy way to add some genuinely beneficial foods to your diet is by buying or increasing your use of onions. Just about any type of onion will offer certain health benefits, but the real champion of the onion family is the shallot. The shallot has the highest anti-oxidant content and may also be beneficial in fighting liver cancer.
