Carbohydrates are little packets of energy, that when taken into the body, release solar energy that powers the organism.
Therefore take no thought, saying, What shall we eat? or, What shall we drink?
or, Wherewithal shall we be clothed? for your heavenly Father knoweth that ye have need of all these things.
Matthew 6:31,32
"Don't be misled by fad diets that make blanket pronouncements on the dangers of carbohydrates. They provide the body with fuel it needs for physical activity and for proper organ function, and they are an important part of a healthy diet. But some kinds of carbohydrates are far better than others."
