While peanuts are actually legumes, in the culinary world they are grouped with other nuts, and Americans enjoy them more than any other. Two-thirds of all nuts consumed in the U.S. are peanuts, according to the Peanut Institute. In addition to their creamy, toasted flavor, they provide nutrients that provide health benefits, including supporting digestive health. Constipation, a condition defined as fewer than three bowel movements each week, affects 4 million Americans annually, and is usually caused by dietary factors, according to the National Institutes of Health. Including peanuts in the diet improves digestion and prevents constipation, but beware of potential allergies that can cause digestive setbacks.
Fat
The fat content in peanuts is relatively high compared with most foods. A 1-cup serving provides 72 g, which is more than the American Dietetic Association daily value of 65 g. Mono- and polyunsaturated fats provide an environment in the intestines beneficial for elimination. Be cautious regarding the saturated fat content, however. The 10 g in one cup of peanuts is half of the 20 g upper daily intake.
Fiber
The fiber in one cup of peanuts equals 12.4 g, which is 50 percent of the 25 g ADA daily value. Fiber is arguably the most important nutrient in the diet for preventing constipation because it forms the bulk of stool that stimulates bowel movements. Most Americans do not include the ADA recommended amount of fiber in their diet each day. Including high-fiber foods is important for supporting all aspects of digestive health, including bowel movement regularity.
Magnesium
The minerals in the body influence fluid balance, and magnesium is particularly effective for hydrating the intestines. Over-the-counter laxative products often include magnesium for this reason. A cup of peanuts provides 245 mg of magnesium, which is 61 percent of the 400 mg ADA daily value.
Allergy
While most of the nutrients in peanuts support bowel health and regular elimination, a peanut allergy has the opposite effect. An allergic reaction irritates the digestive tract lining, which may cause symptoms similar to irritable bowel syndrome, a disorder characterized by irregular bowel movements and unhealthy stool consistency, according to health journal "Professional Nursing Today." A peanut allergy can be extremely serious and cause additional symptoms, including throat swelling and trouble breathing, which require emergency medical care. A physician can determine whether you are allergic to peanuts with a simple allergen test.
