What are some types of foods? Some have fats and some have proteins in them..so what are some of these foods?

Foods are essentially composed of proteins, fats, and carbohydrates.  Most foods have a percentage of all three of these in them, but most are higher in one than the other two.

High protein foods include meat and poultry, fish, eggs and dairy, beans and legumes, and nuts.

High fat foods often include oils and animal fats.  It is important to point out that there are healthy fats and unhealthy fats.  Naturally high fat foods include nuts and seeds, avocados, whole-fat dairy products, and many animal products.  Processed foods are often high in fats (and usually the unhealthy kind).  Some common foods that are generally high in fat include hamburgers, chips, ice cream, pizza, and candy.  Anything fried will be high in fat.

Carbohydrates (carbs) have a bit of a bad reputation, but there is a difference between foods with simple carbs and foods with complex carbs.  The more natural something is, the more likely it is to have the "good" complex carbs.  Whole grains like oats and wheat are good complex carbohydrate sources.  On the other hand, foods high in sugar are typically full of the "bad" simple carbs.  High carb foods include fruit, oatmeal, rice, pasta, breads, and cakes, cookies, etc.

A nutrition label will show the amount of each of these that a product contains.
