Following dietary therapy can be challenging. The Specific Carbohydrate Diet has evolved over the years since Dr. Sydney Haas first reported on it. Since then we have learned much but there is still much more for us to learn. Below are foods that are allowed (legal) and foods that are not allowed (illegal) based off of Dr. Sydney Haas's initial description of the diet and Elaine Gottschal's Breaking the Vicious Cycle and our current research. In addition this food list includes up to date evidence based information on current research in foods.

| Type of Food | SCD Approval | Explanation | NiMBAL Research |
| Quinoa | Illegal | Since quinoa is 60% starch, it is illegal. | Starches have been shown to aggravate IBD symptoms through this review. |
| Quorn | Illegal | A range of meat substitutes which contain mycoprotein and sometimes wheat. | No research has been conducted on the effects of Quorn products on IBD. However, amylase/trypsin inhibitors are found in wheat, which cause intestinal inflammation. |
