The way you prepare your foods also has a great impact on their antioxidants. Most foods lose some of their antioxidant power when you process them, except tomatoes: Their antioxidant capacity is enhanced when you cook them. But in general it is better to consume fresh foods instead of cooked or frozen ones, which is certainly easy with fruit. Its not to say that cooked or frozen is all bad. Sometimes, you simply dont have a choice maybe you dont have time and canned or frozen is quicker. After all, a blueberry pie or homemade raspberry jam will still be healthier than no fruit at all. But try to also fit some fresh foods in every day. Fruit can be an excellent snack or dessert, for example, and they are great for your lunch box, too.
