Feeling a little stopped up lately? It may come down to a lack of fiber consumption. The typical American only consumes around 8-10 grams of fiber per day, mostly from processed food sources. This is far from the recommended amount of 25-35 grams of daily fiber intake! You can find fiber in sources such as fruits, veggies, beans, seeds, and whole grain products like breads, cereals and pastas. It is important to vary your fiber intake as there are two main types of fiber, both with important jobs to do.
Types of Fiber
The first is called insoluble fiber. This is the tough matter found in whole grains, nuts, fruits, and veggies. It cannot be dissolved in water and is not broken down by the gut. Insoluble fiber adds bulk to the waste in our digestive system to help keep us regular.
The second is called soluble fiber. This is found in beans, peas, oats, barley, fruits, and avocados. It absorbs water and creates a gel-like substance inside the digestive tract. This helps to soften the stool so it can more easily slide through our gastrointestinal tract. Soluble fiber also helps with weight management by keeping us feeling fuller, longer.
Be sure to increase your fluid intake as you increase your fiber intake. If you are slightly dehydrated while consuming more fiber than usual, this can create fuller constipation, gas, and bloating. Prevent this problem by drinking an extra glass, or two, of water daily!
