A return to an omnivorous diet aggravated symptoms. The importance of the overall diet cannot be overemphasized. Proper foods keep the intestinal barriers strong and the immune system in a fighting condition. Those foods are whole starches, vegetable, and fruits. When it comes to blaming individual foods, dairy products seem to be the most troublesome foods, causing the most common and severe reactions.
Many reports indicate grains, such as corn and wheat can also aggravate of symptoms.
The truth seems to be almost any food can cause trouble, but few people react to vegetable foods. If no improvement is seen within 2 weeks, I suggest wheat and corn be eliminated. The final step is to follow an elimination diet based on the foods least likely to cause problems, such as sweet potatoes and brown rice with the addition of noncitrus fruits, and green and yellow vegetables. All thoroughly cooked. Water is the beverage.
