Introduction

Dietary fiber is an important part of a healthy diet. It gives you many health benefits. The fiber in your food helps your digestive system stay healthy and work as it should. It can also be good for your heart health and help with your blood sugar levels. You get dietary fiber from foods like fruits, vegetables, legumes, and whole grains. This fiber goes through the body and is not broken down.

Many people in the US do not get enough fiber every day. This is not good for you. When you know why dietary fiber is important and how it helps, you can make better choices with your food. Over time, this will help improve your health and how you feel.

What Is Dietary Fiber and Why Is It Important?

Dietary fiber is a type of carbohydrate that you get when you eat foods like fruits and legumes. The digestive system does not break this fiber down into sugar as it does with other carbs. Because dietary fiber goes through the body without being digested, it gives many health benefits.

Dietary fiber helps to put more bulk in your stool, so it can help you if you get constipation. It lets your digestive system work well. The fiber also keeps your gut health strong. When you eat foods high in dietary fiber, it can lower cholesterol, and keep your blood sugar smooth. Fiber helps you feel full for a longer time. With all this, dietary fiber can be good for weight control. It can also help stop heart disease.

Types of Dietary Fiber: Soluble vs. Insoluble

Soluble fiber is a type of fiber that can dissolve in water. When this is in your stomach, it forms a gel-like feel and slows down your digestion. This can help keep your blood sugar levels more steady and help you feel full for a longer time. Food sources with soluble fiber, like oatmeal, chia seeds, and kidney beans, are good ways to add it to your meals. These foods can also help lower cholesterol levels by sticking to fats in the gut.

Insoluble fiber does not mix with water. It moves through the digestive system in one piece. This type of fiber works like a cleaning brush in the body. It is good for gut health and helps stop constipation. You can get insoluble fiber from foods like whole wheat, broccoli, and cauliflower.

Both soluble fiber and insoluble fiber are important for your health. You should eat a mix of foods like fruits, legumes, and grains that have fiber. This will help your digestive system and your heart because you get all the good things from both types of fiber.

How Fiber Works in the Body

Fiber can help the digestive system in a big way. It takes in water and makes your stool bigger. This helps your stool move along and can make it easy to go to the bathroom. Because of this, you are less likely to get constipation. A better digestive system leads to good gut health.

Foods that have a lot of dietary fiber help you control calories. They help you feel full, so you do not want to eat too much as the day goes on. Fiber also makes food move more slowly through your body. This is good for you.

Healthy fats in avocado and coconut come together with fiber. They give more good support for your gut health.

Dietary fiber helps to keep your blood sugar levels steady. Soluble fiber, which you find in foods like oats and mandarin oranges, can slow how your body takes in sugar. This helps your gut stay healthy. Eating more dietary fiber and soluble fiber may cut down the risk of heart disease and diabetes. The fiber also gives you other good things for your health.

Daily Fiber Recommendations in the United States

How much fiber should you eat each day? The Dietary Guidelines for Americans say that the grams of fiber you need to get will change based on your age and gender. Most adults will need to eat between 22 and 34 grams each day. If you are pregnant or breastfeeding, how many grams of fiber you should get could be different.

To see how much fiber you get, check the nutrition facts label on the food package. You will find the grams of fiber listed under Total Carbohydrates. This helps you know if you get enough fiber for good digestive health. It only takes a moment to look at this each day. Knowing the grams can help us make sure we get what we need.
