Key Do’s and Don’ts of the SCD (Specific Carbohydrate) or GAPS (Gut Psychology Syndrome) Diet

ProduceSCD (Specific Carbohydrate) or it’s modified GAPS (Gut Psychology Syndrome) Diet:

If you are going to go to all the trouble of making huge diet changes, why not go all the way and address all the potential issues?  This is what I believe the GAPS diet does. 

Dairy: If and only if there is no sensitivity or allergy to dairy, then on GAPS, you would only allow fermented yogurt, sour cream and kefir (homemade, natural, organic). Clarified butter (ghee) is usually OK, and as the gut heals, organic, unsalted butter is fine. Eventually, certain cheeses are OK.

Meats and Fish: OK.  Best boiled or slow cooked so easier to digest. Avoid meats that have been commercially altered (deli and lunch meats, ham, hotdogs, sausage)

Eggs:  Initially, and if there are food sensitivities, avoid or just eat the yolks. If there are no sensitivities or allergies, then eggs are OK.

Fruits: All are OK.  Fruit may be best in moderation when there is bacterial overgrowth/dysbiosis,  and best at times other than main meals. Only use home-fresh juices.

Vegetables: Avoid the starches, eat fresh or frozen, and organic. Not canned. French artichoke, asparagus, beets, broccoli, brussel sprouts, cabbage, cauliflower, carrots, cucumber, celery, eggplant, garlic, green beans, onions, kale, lettuce, mushrooms, parsley, peas, peppers, pumpkin, green beans, squash, spinach, tomatoes, turnips, watercress, and zucchini are all great!. Only introduce raw when the gut has healed.

Nuts and Seeds: Most of these are OK. Almonds,  brazil nuts, cashews, hazelnuts, peanuts, pumpkin seeds,  sesame seeds, walnuts, etc.  can all be made into nut butters. Only add salt.

Beans: Some beans may be OK, such as white/navy, lima, and lentils. The rest are too starchy and these may need to be added to the diet later.

Sweetener: Use HONEY! The cold-pressed honey is the best.  Avoid all other sugars and sweeteners.

Drinks: Water, water with lemon, fresh juices, almond milk, coconut milk. For adults, weak tea or coffee. If it is herbal tea, try to obtain it from single fresh herbs.

Oils: Cook with animal drippings/fat, butter, ghee or (at low heat) coconut oil.  If you are adding it to salads, use cold-pressed olive, flax, or avocado oils.
