Toidukiud

Toidukiud, commonly known as dietary fiber, refers to the edible parts of plants that are resistant to digestion and absorption in the human small intestine. These plant-based carbohydrates pass relatively intact into the large intestine, where they can have beneficial effects on the digestive system and overall health. Fiber is broadly categorized into two main types: soluble fiber and insoluble fiber, each with distinct properties and health benefits.

Soluble fiber dissolves in water to form a gel-like substance. This type of fiber is found in foods such as oats, barley, beans, lentils, apples, and citrus fruits. Soluble fiber can help lower blood cholesterol and glucose levels. It is fermented by bacteria in the gut, producing short-chain fatty acids that are beneficial for gut health.

Insoluble fiber does not dissolve in water and adds bulk to the stool. It is found in whole grains, wheat bran, nuts, seeds, and vegetables like cauliflower, green beans, and potatoes. Insoluble fiber helps to speed up the passage of food and waste through the digestive system, promoting regularity and preventing constipation.

A diet rich in dietary fiber is associated with a reduced risk of various health issues, including heart disease, type 2 diabetes, and certain types of cancer. It also contributes to a feeling of fullness, which can aid in weight management. Adequate fiber intake is a crucial component of a healthy and balanced diet.
