Dietary Fibers-Unveiling The Hidden Phenomenon

Dietary Fibers-Unveiling The Hidden Phenomenon


In this article, we will discuss the importance of cholesterol, the effects of Dietary fibres, and diseases caused by low and high cholesterol levels. Cholesterol is a fat molecule produced by the body but isn’t part of the blood. The liver produces it, and several carriers, such as lipoproteins, carry it to the blood to be used by cells. Let’s get into details of how the whole mechanism works:

Production Of Bile

Bile is produced in the liver with the help of cholesterol, and a small amount of bitterness is always present in the gall bladder. The function of bile is the emulsification of fats. Bile surrounds the fat molecules to create small globules, Increasing the surface area for enzymes to act effectively.

Pivotal Role Of Dietary Fibers In Regulating Cholesterol Levels In The Body

Two primary dietary fibres can be found in different food sources, i.e. Soluble and Insoluble Dietary Fiber. Insoluble fibres do not dissolve in water and add fullness to the stool before it passes out. This helps in bowel movements and helps to prevent constipation and diverticular disease. Soluble fibres, on the other hand, are readily soluble in water and can be fermented easily by gut bacteria.

Dietary fibers

Soluble dietary fibres are not digested by the body but are fermented by bacteria in the large intestine. When soluble fibres enter the body, they trap some cholesterol molecules during excretion. So intake of dietary fibres reduces the cholesterol level in the body. Similarly, these fibres also trap glucose molecules which help lower blood glucose levels and help in preventing diabetes.

Sources Of Fibers:

Soluble fibres are found in oats, apples, citrus fruits, barely, carrots, beans, and peas. In contrast, insoluble fibres are found in wheat bran, nuts, potatoes, vegetables such as cauliflower, whole wheat flour etc.


High intake of fats containing food rich in cholesterol and insufficient intake of dietary fibres lead to this disorder; hypercholesterolemia: increased cholesterol level in the body. The primary cause of this disorder is the high intake of saturated fibres, especially from meat and poultry sources.


This disorder is the primary cause of myocardial infarction and stroke. This is because a high level of cholesterol causes excessive deposits in the coronary arteries. It restricts blood flow to the heart and increases the risk of a heart attack.


Hypocholesterolemia is a disorder in which the body faces deficient cholesterol levels, i.e. 160mg/dL. It is a genetic disorder, or poor dietary cholesterol intake provokes hypocholesterolemia in the body. Risk factors of hypocholesterolemia are Stroke, adrenal failure, susceptibility to viruses, anaemia, depression, and chronic inflammation.


Cholesterol plays a critical role in the body. Both low and high levels of cholesterol give rise to life-threatening diseases. Recommended dietary cholesterol intake for adults is 200 to 239 mg/dL. An intake beyond the recommended levels is more likely to cause diseases such as hypercholesterolemia. Give a read to our other blogs as well for more exciting information!
