I often recommend a high quality probiotic to see if a patient is missing some key gut flora before trying to eliminate foods. If you've already tried a probiotic it's time to start eliminating foods that may be difficult for you to digest. A place to start is dairy. Lactose can become difficult to digest as you age. Specifically cow milk and soft cheeses such as cottage cheese, ricotta etc. Hard cheeses such as cheddar may still be OK.

If the above does not help after a four week trial try eliminating, each group one by one, the following grouping of foods:
onion bulbs
broccoli, kidney beans, soybeans
apple, mango, watermelon
agave syrup, high fructose corn syrup (this should be eliminated from everyone's diet!), fruit juice concentrate
cherries, peach apricot, plum, sorbitol, erythritol
So many people pop pills and drink potions to counter these symptoms when the symptoms are simply your body talking to you. It's your body saying, "I can't handle this!"
