WHY CARBOHYDRATES MATTER
Carbohydrates are important because they provide
us with energy and essential vitamins and minerals.
Proteins and fats also contain calories, vitamins,
and minerals, but do not contain carbohydrates
unless the food is a mixed item like a casserole.
Carbohydrates are the primary foods that affect
glucose levels. Nearly 100% of digestible starches
and sugars become glucose within 2 hours of being
eaten—when glucose enters your blood stream, it
raises your blood glucose levels.
Proteins and fats take longer to digest and are
slower to affect your blood glucose (within 2-6
hours). Higher consumption of protein or fat at
meals can delay glucose absorption and create
higher blood glucose levels later*. The section

more about bolusing for certain meals with the

Complex carbohydrates include starchy foods
and foods with fiber like whole grain pasta, beans,
brown rice, or whole wheat bread. Choosing
less processed, whole grain products is not only
more nutritious, but the fiber can have a favorable
affect on your blood glucose and digestive health.
Simple carbohydrates include table sugar,
honey, syrups, regular soda, fruit juice, jellies and
candies. These foods are digested easier and
are absorbed into your blood stream faster than
complex carbohydrates.
