The Specific Carbohydrate Diet is a scientific diet that is based on chemistry, biology, and clinical studies.

The selection of foods that are allowed on the Specific Carbohydrate Diet is based on the chemical structure of these foods. Carbohydrates are classified by their molecular structure.The allowed carbohydrates have a molecular structure that is small enough to be transported across the small intestinal surface into the bloodstream. These carbohydrates do not need to be broken down by various processes of the digestive organs such as the pancreas or the intestinal cells' surface enzymes.

The Specific Carbohydrate Diet is biologically correct because it is species appropriate.The allowed foods are those that early man ate before the agricultural revolution. The diet of early man is one of meat, fish, eggs, vegetables, nuts, low-sugar fruits, and certain oils. Starches, grains, pasta, legumes, and breads have only been consumed for a mere 10,000 years. Many people are not adapted to these types of foods yet.

The Specific Carbohydrate Diet was clinically tested for over 50 years by Dr. Sidney Haas and biochemist Elaine Gottschall with amazing results.
