How does fiber help digestion?

Dietary fiber is considered an essential part of a healthy and balanced diet. Nutrimuscle explains what fiber is, where to find it, its benefits, and the risks associated with excessive consumption.

What is fiber?

Dietary fiber consists of complex carbohydrates that are not digested by our body. Fiber is classified into two main categories: soluble and insoluble fiber.

Soluble fiber, such as pectin, beta-glucans, and gums, dissolves in water and forms a gel in the digestive tract. It slows down the digestion and absorption of nutrients in the digestive system, which can help maintain stable blood sugar levels and reduce blood cholesterol.

Insoluble fiber, such as cellulose, hemicelluloses, and lignin, does not dissolve in water and increases stool bulk, promoting regular bowel movements.

Where can fiber be found?

Fiber is present in a wide variety of foods, especially plant-based foods. Here are some examples of fiber-rich foods.

Fruits and vegetables, especially those eaten with their skin or seeds, are a good source of fiber, as are nuts and whole grains.

Legumes, such as lentils, beans, and chickpeas, are also rich in fiber. It can also be found in whole grains, such as brown rice, oats, and quinoa.

Processed foods, such as refined foods, may have a reduced fiber content due to industrial processing. Moreover, industrial products can also contain food additives, such as artificial sweeteners and preservatives, which are harmful to health in the long term. It is therefore important to prioritize whole and natural foods to increase fiber intake.

Gentle cooking of food can reduce the risk of stomach irritation while preserving the benefits of fiber. Prefer steaming vegetables.

It is also important to follow dosage instructions and drink enough water when taking fiber supplements, as they absorb water in the intestine. Not drinking enough water can lead to side effects such as bloating and abdominal pain.

At Nutrimuscle, we have designed a product that meets legislative recommendations while preserving your health. Nutrimuscle Nutri-fibers, also known as Nutriose®, are carbohydrates produced from wheat starch through partial enzymatic hydrolysis. These dietary fibers are highly soluble and have a neutral taste.

They provide a prolonged release of energy, which helps reduce hunger. Nutrimuscle Nutri-fibers have a low sugar content, less than 0.5%, as well as a low caloric value of only 2 kcal/g. In addition, they have a low glycemic index, which is an advantage for people looking to control their blood sugar levels.

They are often used as a dietary supplement to help increase fiber intake in the diet, especially for people who do not consume enough fiber through their normal diet.

What are the benefits of fiber?

Fiber has many health benefits. It is beneficial for digestive, cardiovascular, and metabolic health.

Maintaining good digestive health

Insoluble fiber increases stool bulk and promotes regular bowel movements. Soluble fiber can also contribute to good digestive health by nourishing beneficial gut bacteria, which can aid digestion.

Weight and appetite control

Fiber intake regulates appetite by increasing feelings of fullness and reducing hunger. This helps control overeating and prevent excessive weight gain.

Reduced risk of cardiovascular disease

By preventing cholesterol absorption in the intestine, soluble fiber reduces blood cholesterol levels. This therefore prevents the risk of cardiovascular disease and strokes.

Reduced risk of type 2 diabetes

One of the actions of fiber is to regulate blood sugar by slowing down the absorption of carbohydrates into the blood. This reduces the risk of developing type 2 diabetes.

Reduced risk of cancer

Fiber also helps reduce the risk of certain types of cancer, such as colorectal cancer, by promoting regular bowel movements and reducing the contact time of toxins with intestinal cells.

Prebiotic effect

Dietary fiber also has a prebiotic effect, meaning it nourishes beneficial bacteria in the gut. By increasing the amount of good bacteria in the gut, dietary fiber helps maintain a healthy balance of intestinal flora. Fiber supplements can also contribute to this effect.

Is there a risk of excess?

Although fiber is beneficial for health, it is important to note that excessive fiber intake can have negative health effects.

Excessive fiber intake can lead to digestive problems such as bloating, gas, and intestinal discomfort.

Consuming too much fiber can also reduce the absorption of certain nutrients, such as iron, calcium, and zinc, which can lead to nutritional deficiencies.

It is recommended to consume between 25 and 30 grams of fiber per day, depending on age, sex, and physical activity level. French people are far from reaching this rate: an average of 15g of fiber is consumed per day per French person. Eating more fiber would better regulate intestinal transit, with a few exceptions.

Indeed, people with certain conditions (such as irritable bowel syndrome) may need to limit their fiber intake, at the risk of worsening their digestive health.

Fiber is therefore an important component of a healthy and balanced diet. It can help maintain good digestive, cardiovascular, and metabolic health. Fiber is found in plant-based foods, and it is recommended to consume between 25 and 30 grams of fiber per day. However, it is important not to consume it in excess to avoid negative health effects.
