Experimental Treatment

Group I: Specific Carbohydrate DietExperimental Treatment1 Intervention

The Specific Carbohydrate Diet emphasizes consumption of specific carbohydrates that require minimal digestion. Therefore, it eliminates most carbohydrates, including grains, starches, dairy and sugars. The idea behind this diet is that it reshapes the microbiome of the intestines. The diet restricts the intake of certain carbohydrates that may increase the growth of "bad" bacteria possibly contributing to inflammation. By restricting the amount of these carbohydrates in the microbiome, the diet aims to reduce their activity in the gut and reduce inflammation.

Group II: Low-Protein/Vegan/Low-Sulfur DietExperimental Treatment1 Intervention

This is a specific diet that is both vegan and low in protein. The vegan diet eliminates all animal products, (including meats, eggs, dairy products) and animal by-products such as honey.
