types of carbohydrates
Complex carbohydrates (or polysaccharides) are built from single-unit sugars joined in long chains. Two types of complex carbohydrates are particularly important for nutrition: Starch: Starch is a polysaccharide that plants use to store energy. It is the main constituent of complex carbohydrates in the human diet. Examples of starchy foods include potatoes, rice, and pasta.
Simple carbohydrates are composed of single-unit sugars called monosaccharides and disaccharides. Glucose and fructose are examples of common monosaccharides. Simple carbohydrates are easily digested and converted to sugar rapidly in the bloodstream. This can cause trouble for people with diabetes.
