In the intricate web of nutrients our bodies need, fiber holds a special place. These unassuming heroes play a crucial role in our health and daily well-being. Let's dive into the world of fiber – what it is, why a fiber-rich diet is important, and what foods contain it.
What is fiber?
Fiber is a type of carbohydrate that is not digested by the digestive system. It is found in plant-based foods such as fruits, vegetables, whole grains, nuts, and seeds. Unlike other carbohydrates, fiber is not broken down and absorbed into the bloodstream; instead, it reaches your stomach and small intestine intact and is then partially broken down by gut bacteria in the large intestine. This breakdown releases substances that, among other things, stimulate bowel movements and are therefore essential for your digestion.
We can distinguish between two types of fiber: soluble fiber and insoluble fiber.
Soluble fiber
Soluble fiber, as the name suggests, dissolves in water. This fiber forms a gel-like substance in the intestines, offering various benefits.
1. Blood sugar regulation
Soluble fiber slows down sugar absorption, which can help stabilize blood sugar levels.
2. Cholesterol reduction
It can lower LDL cholesterol levels by binding to bile acids and removing them from the body.
3. Satiety
Soluble fiber contributes to a longer feeling of fullness, which can aid in weight management.
Foods rich in soluble fiber include chicory, leeks, Jerusalem artichoke, artichoke, banana, apple, asparagus, onion, and garlic. But oats, nuts, seeds, and resistant starch in potatoes, plantains, and rice also contain soluble fiber. Resistant starch only becomes active after it has been cooked or heated and then cooled at least once before eating.
Insoluble fiber
Unlike soluble fiber, insoluble fiber does not dissolve in water. It retains its structure during digestion and offers other important benefits.
1. Improves bowel movements
Insoluble fiber adds bulk to stool and speeds up its passage through the digestive system, preventing constipation.
2. Gut health
It can help prevent diverticulitis and other intestinal problems.
3. Improves nutrient absorption
Insoluble fiber contributes to a healthy gut environment, which promotes nutrient absorption. For example, fiber is necessary for optimal mineral absorption.
Foods rich in insoluble fiber include whole-grain products, seeds, nuts, root vegetables, and dark leafy greens. Also consider parsnips, various types of squash, and various tubers.
Eating a fiber-rich diet is therefore important for a healthy digestive system, and it is preferable to choose a variety of soluble and insoluble fibers. The recommendation for healthy adults is to consume 30 to 40 grams of fiber daily, but some people consume less than 10 grams per day. Our ancestors, who did not suffer from Western diseases, ate 150 grams of fiber per day, from vegetables, stems, bulbs, and tubers!
