Eat a balanced diet—carbohydrates, protein, fat, vitamins, minerals, and fiber, in the correct proportions.  

Eat lots of fresh fruit and vegetables, including raw vegetables.  

Eat whole grains, rather than refined ones (brown rice or foods made from whole wheat flour, for example, as opposed to polished rice and foods made from white flour). 

Get protein from a variety of sources, such as beans, whole grains, nuts, fish, eggs, dairy, poultry, and meat. (Meat and poultry are often not as healthy as they used to be, due to how livestock and poultry are being raised.)  

Prepare your food in a healthy way. Some general guidelines are: Keep foods as close to their natural state as possible, and minimize the use of processed additives.

Choose natural, fresh, whole foods over refined, processed, and artificially enhanced foods, when possible. Severely limit intake of sugar, and avoid white sugar and sugar substitutes. Use (or choose products that use) raw sugar (unbleached/unrefined) or honey.
