The Skinny on Carbohydrates
30 Nov 2011
Carbohydrates are the body’s main source of energy as well as controversy. In many recent fad diets they have recommended drastically reducing carbohydrate intake, which can be detrimental to overall health as these diets don’t differentiate between simple and complex. Here is an over-oversimplified overview of the difference between the two.
Complex carbohydrates are our vegetables and whole grains, and are also found in nuts, seeds, and legumes. They are foods that are usually consumed as they are found in nature. Vegetables, nuts, seeds and legumes aren’t usually too overly processed and are not broken down into simple carbohydrates, it’s the grains where the difference between complex and simple becomes an issue.
Grain complex carbohydrates start out with all their components; bran, germ and endosperm, which in turn means they still have all their nutrients, phytochemicals and antioxidants. They are made up of long chains of sugar molecules that the body needs to break down in order to digest. Since these grains are so “complex” this breakdown can take a while. They offer a sustained source of energy over an extended period of time, due to the fact that the sugar is released into our blood stream as it is broken down.
Grain simple carbohydrates are single sugar molecules that are immediately converted into glucose because there isn’t anything to break down. This causes a fast release of sugar into the blood stream and a spike in blood sugar.
Simple carbohydrates are processed from complex carbohydrates they have the bran and germ removed to give them a longer shelf life. By removing theses two extremely important and life sustaining components of the grain they remove more than half of the B vitamins and 70 percent of the iron, as well as many other beneficial nutrients. By the time whole grains have been turned into white flour, the final product is a pale shadow of the original.
Simple carbohydrates are used to produce breads, pasta cereals, crackers, potato chips, bagels, pretzels, rice cakes, white rice, alcoholic beverages, white flour, puffed rice cereal and pretzels; sweet desserts and other processed “treats”, candies, cookies, cakes, ice cream and soda.
There is another type of simple carbohydrate called fructose, this is found in fruit. The difference between this simple carbohydrate and a processed simple carbohydrate is when you eat the WHOLE fruit you are also ingesting fiber which slows the rate of absorption in the body, as well as a whole slew of vitamin, minerals, phytochemicals and antioxidants. Fruit juice has much of the fiber stripped away (it is treated like a simple carbohydrate in the body), along with some of the nutrient content.
