What is Dietary Fiber?

Dietary fiber is the indigestible part of plant foods that passes through your digestive system largely intact. Unlike fats, proteins, or carbohydrates, fiber isn’t absorbed but it plays a crucial role in regulating digestion, supporting metabolic health, and maintaining bowel regularity.

Types of Dietary Fiber

  • Soluble Fiber: Dissolves in water to form a gel-like substance. It helps lower blood sugar levels and cholesterol. Sources include oats, flaxseeds, and fruits like apples and oranges.
  • Insoluble Fiber: Does not dissolve in water and adds bulk to the stool, aiding in faster elimination. Found in whole grains, nuts, seeds, and vegetables like carrots and spinach.

Both types are essential in a balanced Indian diet, contributing to everything from satiety and weight control to smoother digestion.

What Fiber Does to Your Body

  • Promotes Satiety: High fiber foods increase the feeling of fullness, preventing overeating, a key factor for weight loss.
  • Supports Gut Health: It feeds the beneficial gut bacteria, reducing bloating and improving nutrient absorption.
  • Controls Blood Sugar: Fiber slows the absorption of sugar, helping manage blood glucose spikes, especially important for diabetics.
  • Reduces Cholesterol: Soluble fiber binds to cholesterol in the intestines and helps flush it out.
  • Improves Bowel Regularity: Prevents constipation and promotes a healthy digestive rhythm.

Effects of Fiber Deficiency on the Body

  • Chronic constipation or irregular bowel movements
  • Elevated blood sugar and insulin resistance
  • Higher cholesterol levels
  • Increased hunger and risk of overeating
  • Weakened gut microbiome
  • Weight gain and bloating

Over time, fiber deficiency may also increase the risk of conditions like type 2 diabetes, colon cancer, and cardiovascular disease.
