What Is Dietary Fiber?

Dietary fiber is a plant-based nutrient essential for digestive health. Unlike proteins, carbohydrates, and fats, dietary fiber isn’t digested or absorbed by the body. Instead, it moves through the digestive system, aiding in bowel health and regulating sugar levels.

Nutrient	Digestibility	Role in Body
Carbohydrates	Fully digested	Energy supply
Proteins	Fully digested	Body repair and growth
Dietary Fiber	Not digested	Supports digestion

Historical Insight:
The concept of dietary fiber dates back to ancient India, where high-fiber diets were integral to Ayurveda. Grains like millets and pulses were staples in traditional diets.

Types of Dietary Fiber

1. Soluble Fiber:
   Found in oats, nuts, and seeds, soluble fiber dissolves in water, forming a gel-like substance. It lowers blood cholesterol and sugar levels.
2. Insoluble Fiber:
   Present in whole grains and vegetables, this type doesn’t dissolve in water but adds bulk to stool, promoting regularity.

Type	Source	Primary Benefit
Soluble Fiber	Oats, lentils	Regulates blood sugar
Insoluble Fiber	Wheat bran, carrots	Prevents constipation

Health Benefits of Dietary Fiber

Dietary fiber offers a range of benefits:

1. Improves Digestion: Reduces constipation and supports gut health.

Historical Perspective:
In the 1960s, Dr. Denis Burkitt, a British surgeon, popularized fiber’s role in preventing diseases like colon cancer and heart issues.
