A Quick Glance – Carbohydrate (Carbs), Protein & Fat

Carbohydrates, proteins, and fats are called the “macronutrients.”

Carbs - to fuel our bodies,

Protein -  to keep all our muscles and glands healthy, and

Fats - for hormone production and for a healthy nervous system. 

Healthy Choices -
While protein sources and fat sources are pretty straight forward, it is a bit more difficult to know how to choose carbohydrates. You will be able to eat more volume if you choose the low-starch vegetables and the low-sugar fruits. Junk foods like soft drinks, candy, cookies, and other sweets should be enjoyed only as occasional treats. 

Here is a list of fruits and vegetables grouped into high starch and low starch. You can use this list to balance your menus. Remember that pastas, breads, and grains have a higher starch content than the green and colored vegetables. A serving of pasta or potatoes should only be about one-half cup, while a serving of low starch vegetables is equal to about 2 full cups.
