Want to keep your cut produce, like an avocado or apple, from turning brown? Squeeze some lemon on it. The ascorbic acid will help reverse the oxidation process.

Potatoes are not bad for you, it's the way you prepare and dress them might be less than ideal. They actually are high in fiber (the skin), vitamins C and B6 and have more potassium than a banana. And, they are a vegetable that just happens to be high in complex carbohydrates. Eaten alone, potatoes have the ability to spike your blood sugar, but when you pair them with some protein and fat, you slow down the absorption and keep that blood sugar balanced.
