Best diet for resolving your autoimmune, digestive, or skin condition is the Specific Carbohydrate Diet! What this does is remove the fermentable carbohydrates from your diet.
The reason why this helps so much is - your autoimmune, digestive, or skin condition are created from infections and overgrowths from your small intestine. When you cut out the foods that are feeding these infections & overgrowths, you can get less negative reactions from them.
When you have infections or overgrowths in your body, they’re eating nutrients from your food and dumping isopropyl alcohol, lactic acid and phenol into your body making your digestive system very acidic. They also create inflammation in your intestinal lining which creates inflammation all over your body.
The more severe the infection (symptoms) generally the stricter we have to be with SCD diet. However, usually minimising the fermentable carbohydrates and minimising toxic load on the body through a cleanse is enough.
