Dietary fibers are essential for digestion as they promote intestinal transit, prevent constipation, and contribute to better absorption of nutrients by the body.
Dietary fibers, know this, are like the discreet heroes of intestinal transit. Since they are not digested by our bodies, they pass through the intestine smoothly while absorbing water along the way, much like a sponge would. As a result, stools increase in volume and become softer, thus facilitating their journey. Quite clever, isn’t it? This ability helps to avoid the unpleasant phenomenon of transit that is too slow or too fast, contributing to a regular intestinal rhythm. Eating enough fiber, especially when they are soluble (like in certain grains, fruits, or vegetables), is therefore essential for a hassle-free transit.
Your gut hosts a kind of small living community called the gut microbiome, filled with billions of bacteria and microbes that work for your health. The dietary fibers you eat reach the colon intact, where they serve as snacks for these good gut bacteria. By eating fibers, you provide them with everything they need to multiply, diversify, and create a pleasant environment: a well-balanced microbiome. The result? Your microbiome becomes stronger, more varied, and better protects you against intestinal inflammation or the proliferation of harmful bacteria that cause digestive issues. And since your microbiome also impacts immunity and mood, by nurturing your gut bacteria with fibers, you take care of your overall health.
Dietary fibers act a bit like a sponge in the intestine: they absorb water and swell, making stools softer and bulkier. This greatly facilitates their passage and significantly reduces the risk of constipation. Even better, regular consumption of fibers decreases the frequency of common digestive issues like bloating, diverticulosis, or even hemorrhoid flare-ups. Overall, fibers make your digestion much easier on a daily basis.
Dietary fibers slow down the absorption of sugar in the blood. They form a kind of viscous gel in the intestine, which slows down the entry of glucose into the bloodstream. As a result, there are fewer spikes in blood sugar after meals, which is useful for avoiding cravings and energy crashes in the middle of the afternoon. In the long term, it even helps prevent issues related to type 2 diabetes, thanks to better stability of blood sugar levels. Not bad for something we can't even digest, right?
Did you know that legumes like lentils and chickpeas contain both soluble and insoluble fibers, making them great allies for balanced digestion?
Dietary fibers do not provide calories because the human body lacks the enzymes needed to fully digest them. However, they play a crucial role in the sensation of fullness and the regulation of digestion.
Regular consumption of dietary fibers could significantly reduce the risk of developing certain chronic digestive disorders, such as irritable bowel syndrome and diverticulosis.
Brown rice contains on average twice as much fiber as white rice, due to the preservation of the bran and germ during its processing.
Yes, dietary fibers can help control body weight. They create a prolonged feeling of fullness, which can reduce excessive food intake and contribute to maintaining an ideal weight in the long term.
You can increase your fiber intake by consuming more vegetables, fruits, whole grains, legumes (lentils, beans), nuts, and seeds each day. Try to replace refined grain products with whole grain equivalents and incorporate more plant-based foods into each of your meals.
Yes, although they are beneficial, excessive fiber consumption (beyond about 50 to 60 grams per day) can cause bloating, abdominal pain, or occasional constipation. To avoid these discomforts, gradually incorporate fiber into your diet while increasing your water intake.
Soluble fibers dissolve in water to form a gelatinous substance, slowing digestion and helping to control blood sugar and cholesterol levels. Insoluble fibers do not dissolve in water and aid intestinal transit by increasing stool bulk, thereby reducing the risk of constipation.
Fiber supplements can be helpful to complement your fiber intake, especially if your diet is lacking. However, natural fibers from foods are to be prioritized, as they are associated with other beneficial nutrients (vitamins, minerals, antioxidants...) that are essential for health.
