Cauliflower provides essential vitamins, minerals and nutrients, but it can also cause stomachaches or abdominal cramps. The culprit behind the stomachaches is cauliflower’s fiber content, which becomes most troublesome when you increase your fiber intake too rapidly without giving your body time to adjust. Stomachaches join other side effects of overloading on fiber.

Fiber Basics

Fiber is an essential dietary component found naturally in fruits, whole grains and vegetables such as cauliflower. Fiber helps with digestion and absorption of nutrients and gives you a feeling of fullness, which can result in eating less and losing weight. Fiber can also lower your cholesterol levels, decrease your risk of diseases such as type 2 diabetes, certain cancers and heart disease. Moderation is key, however, as rapidly increasing your fiber intake can cause side effects.

Side Effects

Stomachaches are just one side effect from eating large amounts of cauliflower or other fiber-rich foods. Other side effects include gas, bloating and diarrhea. The most effective way to sidestep the side effects is to increase your fiber intake slowly. The Family Doctor website suggests increasing your fiber intake with a single change, such as a regular addition of cauliflower or other fibrous food, and then letting your body adjust for up to a week before making a second change. Drinking water also aids in fiber digestion.

When To Call Your Doctor

If your stomach pain does not go away, you should know when to contact your doctor. If your stomach pains are sudden and sharp; accompanied by pain in your chest, neck or shoulder or tenderness in your abdomen, the National Institutes of Health recommends you seek immediate medical care. Other situations that require emergency attention are if you have stomach pain and you are pregnant, undergoing cancer treatments, have difficulty breathing, vomiting or have signs of internal bleeding such as black or tarry stools.
