Most fruits and vegetables serve as an excellent source of fiber, which provides innumerable health benefits. Fiber helps you maintain a healthy weight, and reduces your risk of diabetes and heart disease, reports MayoClinic.com. Two types of fiber exist: soluble and insoluble. Soluble fiber in peas, beans, apples, citrus fruits and carrots helps lower your glucose levels and blood cholesterol. Whereas insoluble fiber in green beans, cauliflower and potatoes keeps your digestive flow on track by helping materials move easily through your digestive system and creating bulkier stools. Noshing on fiber-laden foods will help adults to meet their recommended daily intake, which is 25 grams for women and 38 grams of men per day. That being said, don’t rush to add too much fiber in your diet as it could promote cramping, abdominal bloating and intestinal gas. Adopt a slow and steady approach to increase fiber in your diet as this will give adequate time to intestinal bacteria to adjust to this change.
