All You Need To Know About Dietary Fibers

Farm market fruitsAlthough everyone has heard that we should have a diet containing an important amount of fibers because they are good for our health, not many of us know exactly what fibers are and what is their beneficial role in people’s health.

What are dietary fibers?

To start with a definition, dietary fibers are carbohydrates found in fruits, vegetables and cereals, which the body can’t process. There are different types of fibers, depending on their origin or on their ability to be diluted in water, but what is more important to know is the impact they have on the human body.

The benefits of dietary fibers

For the digestive system, fibers are bliss. First, they prevent or reduce constipation, as the intestines are quite sensitive to them. Remember, if your diet doesn’t include fibers, it’s a good idea to introduce them gradually.

Second, they change the nature of the bacteria found in the intestines. Researchers at the University of Illinois found out that dietary fiber can turn bad bacteria into good bacteria, which releases healthy substances for the organism.

Third, researchers in Assam, India, encourage people to eat fibers in order to avoid excessive gas and abnormal stool, problems encountered especially in developed countries with a tradition in the fast-food industry.

Fiber intake can do miracles for the heart: the Harvard School of Public Health explains that one of the most serious heart conditions is the one produced by high quantities of cholesterol blocking the arteries, causing heart attacks. Having a diet rich in fibers may prevent heart attacks, because the bad cholesterol (LDL) is partly eliminated.

Fibers lower the risk of developing type 2 diabetes, along with having an active lifestyle. This type of diabetes is the most popular one and is most likely to appear due to a diet lacking vegetables and fruit, to a sedentary way of life and to smoking.

In order to stay healthy, choose a fiber-rich diet: add more fruits and vegetables as meals or as healthy snacks and try to stick with whole grain products.
