Good or Bad Carbs??

Carbohydrates can be either simple (nicknamed "bad") or complex (nicknamed "good") based on their chemical makeup and what your body does with them. Complex carbohydrates, like whole grains and legumes, contain longer chains of sugar molecules; these usually take more time for the body to break down and use. This, in turn, provides you with a more even amount of energy, according to Sandra Meyerowitz, MPH, RD, a nutritionist and owner of Nutrition Works in Louisville, Ky.

Simple carbohydrates are composed of simple-to-digest, basic sugars with little real value for your body. The higher in sugar and lower in fiber, the worse the carbohydrate is for you — remember those leading indicators when trying to figure out if a carbohydrate is good or bad.

Complex carbohydrates are considered "good" because of the longer series of sugars that make them up and take the body more time to break down. They generally have a lower glycemic load, which means that you will get lower amounts of sugars released at a more consistent rate — instead of peaks and valleys —to keep you going throughout the day.

The bottom line: Just be sensible about the carbs you choose. Consider the levels of sugar and fiber in carbs, and focus on healthy whole grains, fruits, and veggies to get the energy your body needs every day.
