Eating a lot of dried fruit can indeed cause gas for some people. Here are a few reasons why: Fiber-rich - Dried fruits are condensed sources of fiber. They contain up to three- to five times more fiber per serving compared to fresh fruit. Remember, fiber is not easily digestible, so it can cause gas as it passes through our digestive systems. The high sorbitol content in some dried fruits can also act as a natural laxative. Fructose - Dried fruit has a higher concentration of fructose than fresh fruit. Fructose is on the FODMAP list (see Question 4) that some people don't absorb well, causing the partially-digested fruit to ferment in the colon - which produces gas. Sulfur dioxide - Some dried fruits such as apricots, prunes, and raisins are treated with sulfur dioxide as a preservative when you buy pre-packaged dried fruit. Sulfur dioxide can cause gas and bloating in sulfur-sensitive individuals. Chewing and swallowing - As you know, dried fruit is sticky and dense. We may easily swallow larger pieces that we didn't chew properly, making it harder to digest, therefore causing more gas. Portion sizes - It's easy to overeat dried fruits since their condensed nature tricks us into thinking we haven't eaten "that" much. Overeating dried fruit can increase gas. So in summary, fiber, fructose, sulfur dioxide treatment, and condensed calories can make dried fruit a gas-producing food for some people who are prone to gassiness. Moderating portions and drinking plenty of water can help reduce undesirable gas and bloating when eating dried fruit.
