Why is Fiber so Fabulous?

Dietary fiber is an essential part of a healthy diet, providing numerous health benefits that help support the digestive system and overall wellness. Despite its significance, many people still don’t consume enough fiber daily. What is fiber and why does your doctor say to eat more of it?  What are the best sources of fiber and how can you eat enough? 

What is Fiber?

Dietary fiber is a type of carbohydrate found in plant-based foods that the body can’t digest. Unlike other carbs that break down into sugar molecules, fiber passes through the digestive system largely intact. This characteristic gives fiber its unique ability to regulate the body’s use of sugars, helping to keep hunger and blood sugar levels in check.

Types of Fiber

There are two main types of dietary fiber:

1. Soluble Fiber: This type of fiber dissolves in water to form a gel-like substance. It helps lower blood cholesterol and glucose levels. Good sources include oats, barley, nuts, seeds, beans, lentils, and some fruits and vegetables.

2. Insoluble Fiber: This type of fiber does not dissolve in water and adds bulk to the stool, which helps food pass more quickly through the digestive system. It is found in whole grains, wheat bran, vegetables, and fruits with edible skins or seeds.

Health Benefits of Fiber

• Improved Digestive Health: Fiber helps maintain bowel health by normalizing bowel movements and preventing constipation.

• Heart Health: A high-fiber diet can lower cholesterol levels, reducing the risk of heart disease. Soluble fiber, in particular, helps reduce low-density lipoprotein (LDL), or “bad” cholesterol.

• Blood Sugar Control: Soluble fiber can help slow the absorption of sugar and improve blood sugar levels, which is especially beneficial for people with diabetes.

• Weight Management: Fiber-rich foods tend to be more filling than low-fiber foods, which can help control appetite and support weight loss efforts.

• Lower Risk of Certain Diseases: Diets high in fiber are linked to a reduced risk of developing conditions such as colorectal cancer, type 2 diabetes, and cardiovascular disease.
