If you want to eat healthy, it is important to make healthy choices in what you eat all the time – meaning: meals and snacks.
For example: foods with refined grains, such as white flour or refined wheat, have high amounts of starch that the body just stores away and doesn't use. Try to eat more whole grains such as whole wheat (bread, etc.), brown rice, and oats – which provide energy over a longer period of time after you eat them.
