None of that will cure you, but usually a combination of Medication's, dietary changes and supplements will help the most. Here is some of what helped me through. I've tested lots of stuff and how it affects my disease over 7 years. some of the diet info may be difficult to apply because I make everything from scratch but you can still use it to generally guide your decisions as for what to eat.
1. Vitamin d- 2000iu in summer, 4000iu in winter. studies show this helps reduce crohn's symptom's.
2. be selective with carbohydrates- avoid simple and refined sugars like soda, white sugar and consume low sugar fruits like cranberries, apples, grapefruit. reduce intake of grapes, raisins or banana.
Avoid lactose in milk, eat cheese for calcium instead and consider calcium supplements calcium carbonate is fine.
complex carbs like rice corn and potatoe can cause problems, I find oats, well cooked pinto beans, and some brands of whole wheat are fine. White bread without iron is also tolerable. there is a book called breaking the vicious cycle that is a special diet developed around this idea to help treat IBD and other conditions the diet is called the specific carbohydrate diet or SCD diet. It's tough to adhere to and also includes making you own yogurt, I've tested many principles in the book and tried to summarize it for you here but read the book sometime.
3. low fod maps- these are certain fermentable carbs and fibers in food that seem to irritate ibd like onions and garlic.
4. be aware of your omega 3/6 ratio of fats, consume and cook with canola instead of corn oil, don't eat butter or fatty meats like sausage or bacon. take a little fish oil but not alot. I get fat from walnuts, unshelled pistachios, canola oil, and whole olives.
5. make an herbal tea- this can kill bacteria that try to live in your gut cause symptoms I use green tea, basil, italian herb blend, cumin, clove, fresh ginger, black pepper.
6. drink irradiated water so that any microorganisms are killed that might invade your gi tract.
7. vitamins e and c, these will help boost your immune system to fight of bacteria in you body. Take 500mg of vitamin c every day and Vitamin e 400iu tocopherol once per week only. you can also take one tocotrienol pill once per week as well.
8. probiotics- take VSL#3 as this is been used to treat pouchitis and U.C. and probably the best on the market. I take 50 bill per day and I believe taking more may be better, this doesn't do that much actually for crohn's but I've noticed more benefits for my anxiety and depression.
9. Resveratrol I use this supplement but small amount and it suppresses some symptoms, I use about 1/10 of one capsule per day, doctors best brand, this is optional though. Turmeric is something else I use occasionally but i find turmeric has side effects but it does suppress symptoms I use about 1/8- 1/4 teaspoon in my tea when i use it.
10. cook your veggies and don't eat them raw. start with broccoli cauliflour soybeans spinach. slowly test others as you go.
11. Avoid anything with sucralose or artifical sweeteners, carageenan, synthetic fibers derived from cellulose, arginine supplements, any supplements with high amounts of niacin or inositol.
12. If you are really adventurous you can look into fecal microbiota transplants follow the link below its good to learn about them anyways.Some scientists believe it has cured people and I have tried 4 of them with some benefits derived and planning to do it again. Here is my article/blog:
