There is much misunderstanding
in the general public as to the value of carbohydrates in our diets. While the
debate continues over what percentage of our meals should consist of
carbohydrates, there seems to be consensus on the types of carbohydrates we
should be consuming. Carbohydrate foods are sugars and starches. Starches are
converted by the body into sugar. The more complex the starch, the more time
it takes the body to convert it into sugar (glucose).
A moderate-to-large quantity of
fat in a meal significantly slows stomach emptying time.1 A high-fiber meal
similarly delays stomach emptying time. In effect, this turns the meal into a
"timed-release food capsule" The food is digested over two to four
hours, slowly trickling sugar into the bloodstream, thereby avoiding
insulin-induced hypoglycemia. In contrast, the typical
high-sugar/carbohydrate, low-protein, low-fat, low-fiber meal like
sugar-loaded breakfast cereals, pancakes, toast, or snack foods may be
digested and absorbed within 20-45 minutes, bringing about a
brain-and-body-dysfunction which produces a rapid blood sugar rise followed by
an insulin-induced blood sugar crash. It is specifically this sensing of low
blood sugar by the brain that results in the typical roller coaster
carbohydrate cravings that plague so many overweight people.
Most sugars and carbohydrates
are refined. Our modern food processing separates most of the sugar or starch
of a plant from the rest of the plant's fiber and most of its vitamins,
minerals and other nutrients. Over-cooking usually removes any of the rest of
the nutrients. We are left with carbohydrates that are not complex enough to
allow the body time to slowly process the sugar to be used for energy. The
sugar immediately enters the bloodstream setting up the body for poor health
conditions manifested in many ways, including ADD symptoms and the "highs
& lows" of hypoglycemia with resultant carbohydrate cravings. The
following carbohydrate chart is by no means complete, but gives a sampling of
both complex and refined carbohydrates.
