Question

plant sterols select one: a. reduce cholesterol absorption from the small intestine. b. increase the absorption of dietary fiber from the small intestine. c. decrease the ability of cholesterol to bind to artery walls. d. decrease trans fat formation in fried foods.

Answer 1

Plant sterols, like sitosterol, reduce cholesterol absorption from the small intestine, helping to lower blood cholesterol levels and reduce the risk of atherosclerosis.

Step-by-step explanation:

Plant sterols, such as sitosterol, are known to help manage cholesterol levels in the body. The statement that plant sterols reduce cholesterol absorption from the small intestine is correct. They work by blocking the absorption of cholesterol in the gastrointestinal tract (GIT), leading to increased fecal excretion of both cholesterol and bile acids. This mechanism helps to lower serum total cholesterol levels and prevents elevated cholesterol from depositing in the tissues, which mitigates the risk of atherosclerosis. Additionally, dietary lipids, including plant sterols, are important for the absorption of fat-soluble vitamins such as A, D, E, and K, needed for various bodily functions.

Plant sterols, such as sitosterol, reduce cholesterol absorption from the small intestine. They block the absorption of cholesterol in the gastrointestinal tract (GIT), preventing its entry into the bloodstream. This reduces the overall cholesterol levels in the body.
