Fiber is an essential nutrient that many people overlook. It is a type of carbohydrate that cannot be broken down by the body’s digestive enzymes, meaning it moves through the digestive system relatively undigested.
While this might seem like a negative, it actually has many benefits for the body. In this article, we’ll cover everything you need to know about fiber, including its types, sources, benefits, and daily recommendations.
Types of Fiber
There are two main types of fiber: soluble and insoluble. Soluble fiber dissolves in water and forms a gel-like substance in the digestive system. This helps slow down digestion and can help lower cholesterol levels.
Sources of soluble fiber include oats, nuts, seeds, beans, lentils, fruits, and vegetables. Insoluble fiber, on the other hand, does not dissolve in water and helps keep the digestive system moving. It also adds bulk to stools and can help prevent constipation.
Sources of insoluble fiber include whole grains, bran, nuts, seeds, and some fruits and vegetables.
Fiber Sources
There are many sources of fiber, both soluble and insoluble. Some of the best sources include:.
Whole Grains
Whole grains are a great source of fiber. They include foods like brown rice, quinoa, whole wheat bread, and oatmeal. When choosing grains, look for ones that are labeled “whole grain” or “100% whole wheat.”.
Nuts and Seeds
Nuts and seeds are another great source of fiber. They also contain healthy fats and essential nutrients. Some good options include chia seeds, flaxseeds, almonds, and pistachios.
Fruits and Vegetables
Fruits and vegetables are an excellent source of fiber. They also contain essential nutrients, like vitamins and minerals. Some great options include berries, broccoli, apples, and sweet potatoes.
Beans and Lentils
Beans and lentils are packed with fiber. They’re also a great source of protein and other essential nutrients. Best options include black beans, chickpeas, and lentils.
