Pectin- Soluble Fiber in Fruits that may Reduce High Cholesterol

Table of Contents


High blood
cholesterol levels can be very dangerous to
our health as they are associated with a higher risk of cardiovascular
diseases such as atherosclerosis and coronary heart disease1.
A proper dietary plan and lifestyle changes are required to reduce blood
cholesterol levels, and it is a known fact that some particular food types may help in this regard.

cholesterol levels could be actually reduced
with specific dietary restrictions. However, modern nutritional approaches
favor a modification of dietary habits, rather than just restricting the
overall amount of daily food intake. Oil-rich foods that contain high levels of
saturated fats are often substituted with fruit and vegetables because of their high
content of soluble fibers such as pectin. Pectin is a fiber found in grapefruit,
lemon and apples as well as in other fruits and vegetables and it is known to
reduce cholesterol levels2.

The exact mechanism through which pectin may reduce plasma cholesterol levels is still unclear. However, several mechanisms have been proposed, including a decreased cholesterol absorption and modifications of the intestinal microflora environment. An inhibition of bile acids re-absorption has also been suggested, as pectin can partially interrupt their enterohepatic circulation3. Pectin gelification into an extremely viscous fluid within the gut could also help by sequestering micelles that contain cholesterol, which are then eliminated with the feces.
