A food with a high GI raises blood glucose more than a food with a medium or low GI. Meal planning with the GI involves choosing foods that have a low or medium GI.
July 14, Elena Schweitzer Shutterstock Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products. Though often maligned in trendy diets, carbohydrates — one of the basic food groups — are important to a healthy life. The American Diabetes Association notes that carbohydrates are the body's main source of energy.
They are called carbohydrates because, at the chemical level, they contain carbon, hydrogen and oxygen. There are three macronutrients: Macronutrients are essential for proper body functioning, and the body requires large amounts of them.
All macronutrients must be obtained through diet; the body cannot produce macronutrients on its own. Carb intake for most people should be between 45 and 65 percent of total calories.
One gram of carbohydrates equals about 4 calories, so a diet of 1, calories per day would equal about grams on the low end and grams of carbs on the high end.
However, people with diabetes should not eat more than grams of carbs per day, while pregnant women need at least grams.
Function of carbohydrates Carbohydrates provide fuel for the central nervous system and energy for working muscles. They also prevent protein from being used as an energy source and enable fat metabolism, according to Iowa State University.
Also, "carbohydrates are important for brain function," Smathers said. They are an influence on "mood, memory, etc. Two recent studies published in PNAS have also linked carbs to decision-making. In the studies, people who ate a high-carbohydrate breakfast were less willing to share when playing the " ultimatum game " than those who ate high-protein breakfasts.
Scientists speculate this may be caused by baseline dopamine levels, which are higher after eating carbohydrates. This doesn't mean carbs make you mean, but underscores the importance of a balanced diet. The difference between the two forms is the chemical structure and how quickly the sugar is absorbed and digested.
Generally speaking, simple carbs are digested and absorbed more quickly and easily than complex carbs, according to the NIH.
Simple carbohydrates contain just one or two sugars, such as fructose found in fruits and galactose found in milk products. These single sugars are called monosaccharides. Carbs with two sugars — such as sucrose table sugarlactose from dairy and maltose found in beer and some vegetables — are called disaccharides, according to the NIH.
Simple carbs are also in candy, soda and syrups. However, these foods are made with processed and refined sugars and do not have vitamins, minerals or fiber.
They are called "empty calories" and can lead to weight gain, according to the NIH. Complex carbohydrates polysaccharides have three or more sugars. They are often referred to as starchy foods and include beans, peas, lentils, peanuts, potatoes, corn, parsnips, whole-grain breads and cereals.
Smathers pointed out that, while all carbohydrates function as relatively quick energy sources, simple carbs cause bursts of energy much more quickly than complex carbs because of the quicker rate at which they are digested and absorbed.
Simple carbs can lead to spikes in blood sugar levels and sugar highs, while complex carbs provide more sustained energy. Studies have shown that replacing saturated fats with simple carbs, such as those in many processed foods, is associated with an increased risk of heart disease and type 2 diabetes.
Smathers offered the following advice: The small intestine absorbs these smaller units, which then enter the bloodstream and travel to the liver. The liver converts all of these sugars into glucose, which is carried through the bloodstream — accompanied by insulin — and converted into energy for basic body functioning and physical activity.You will learn how to test for each of these organic molecules by clicking on the boxes below.
