Complex carbohydrates
Complex carbohydrates are made up of sugar molecules that are
strung together in long, complex chains. Complex carbohydrates are
found in foods such as peas, beans, whole grains, and vegetables.
The body turns both simple and complex carbohydrates into glucose
(blood sugar). Glucose is used in the cells of the body and in the
brain. Any unused glucose is stored in the liver and muscles as
glycogen for use later.
Complex carbohydrate foods provide vitamins, minerals, and fiber
that are important to the health of an individual. The majority of
carbohydrates should come from complex carbohydrates (starches) and
naturally occurring sugars, rather than processed or refined
sugars, which do not have the vitamins, minerals, and fiber found
in complex and natural carbohydrates. Refined sugars are often
called "empty calories" because they have little to no nutritional
value.
