About Dietary Fibre

Dietary fibre is the indigestible part of plant foods that passes through our digestive system relatively intact. It is essential for digestive health and offers numerous health benefits.

Types of Fibre
  • Soluble Fibre: Dissolves in water to form a gel-like substance. It helps lower blood cholesterol and glucose levels. Found in oats, peas, beans, apples, citrus fruits, carrots, and barley.
  • Insoluble Fibre: Promotes the movement of material through your digestive system and increases stool bulk. Found in whole grains, wheat bran, nuts, beans, and vegetables like cauliflower and potatoes.
Health Benefits
  • Digestive Health: Normalises bowel movements, helps maintain bowel health, and reduces constipation.
  • Weight Management: High-fibre foods tend to be more filling, helping you stay satisfied with fewer calories.
  • Blood Sugar Control: Soluble fibre can slow the absorption of sugar, helping to improve blood sugar levels.
  • Heart Health: Soluble fibre helps lower cholesterol levels by binding with cholesterol particles and removing them from the body.
  • Longevity: Studies suggest high-fibre diets are associated with reduced mortality from cardiovascular disease and all cancers.
Recommended Intake

The Dietary Guidelines for Americans recommend:

  • Men: 30-38 grams per day depending on age
  • Women: 21-25 grams per day depending on age
  • Pregnant Women: 28 grams per day
  • Lactating Women: 29 grams per day
  • Children: Age + 5 grams per day (e.g., a 10-year-old needs about 15 grams)
Increasing Fibre Intake

When increasing fibre intake, it's important to do so gradually and drink plenty of water. A sudden increase in dietary fibre can lead to gas, bloating, and cramping.
