SCD, or the specific carbohydrate diet, is a dietary program designed to help manage chronic digestive diseases including Crohn's disease, ulcerative colitis, diverticulitis, celiac disease, chronic diarrhea and cystic fibrosis. However, the diet is safe and healthy for all individuals, according to the SCD website. When it comes to carbs, SCD allows only monosaccharides -- or simple carbohydrates that consist of a single sugar molecule and are easily digested. Complex carbohydrates, which include disaccharides and polysaccharides, are not allowed.
SCD is based on the premise that humans evolved over millions of years to eat fish, meat, eggs, vegetables, nuts and low-sugar fruits. Since humans have consumed many of the food staples included in the modern diet, such as grains, legumes, starches, pastas and breads, for only the last 10,000 years, these foods are not easily digested and can thus cause a range of health problems including obesity, brain disorders and bowel disorders, notes the SCD website, which also adds that the specific carbohydrate diet has been clinically tested for over 50 years with credible results.
