Examples of these complex carbs are whole grains, most fruits and vegetables. Legumes, plants of the pea or bean family, are also in this category.
 
WHICH IS BEST????

While studies like one from the University of Arkansas for Medical Sciences in January of 2004 show that low-carb diets can help with weight loss; the carbs need to be of the complex, low-glycemic type. Notable is that a total avoidance of the simple carbs is not necessary, either. In other words a treat now and then, in moderation (and approved per your dietary advisor or in accordance with your health practitioner), should be fine.

As a side note, your teeth will also be healthier without the build up of sugar decay from simple carb foods.  So healthier smiles will shine with healthier bodies.

OTHER HELPFUL TERMS

Here are some other terms to help explain the science and health issues behind low-carbohydrate dietary planning solutions. Note these are only basic definitions and can be explored at your leisure through other resources to further define their roles in the body’s health system.

CALORIE
A calorie is a measure of heat. Calorie also refers to a measure of the amount of energy a body gets from food. In a nutshell, the more calories in food, the more energy is required for the body to use up the nutrients.

CARBOHYDRATE
A carbohydrate is one of three major nutrients that provide the body with energy. Carbohydrates are made up of either single sugars or bound strings of sugar. Examples of single sugars (simple carbohydrates) are sucrose or table sugar, fructose or fruit sugar and lactose or dairy sugar. Bound strings of sugar or complex carbohydrates that are found in plants are often called starches. Examples of digestible kinds of complex carbs are wheat flour or potato starch. A non-digestible example is cellulose from celery. Carbs are converted by the body into sugar and used for energy. Unused carbs are stored in the body as fat.
