Phenolic acids, a class of polyphenolic compounds found abundantly in plant foods such as fruits, vegetables, coffee, and whole grains, have been studied for their potential cholesterol-lowering effects. Scientific evidence, primarily from in vitro, animal, and some human studies, suggests that certain phenolic acids—such as ferulic acid, caffeic acid, and chlorogenic acid—may help reduce high cholesterol levels. The mechanisms proposed include inhibition of cholesterol absorption in the intestines, upregulation of LDL receptor activity, and antioxidant effects that protect LDL from oxidative modification.

Several clinical studies, although limited in size and duration, have observed modest reductions in total cholesterol and LDL cholesterol following consumption of phenolic acid-rich foods, such as coffee and whole grains. For example, chlorogenic acid from coffee has been associated with decreased absorption of dietary cholesterol and improved lipid profiles in some trials. However, results are not entirely consistent, and the magnitude of effect is generally modest compared to pharmaceutical interventions.

Overall, the evidence supporting the use of phenolic acids for high cholesterol is promising but not conclusive. More large-scale, well-controlled clinical trials are needed to clarify the efficacy and optimal dosing. Nevertheless, inclusion of phenolic acid-rich foods as part of a balanced diet is supported by current evidence for cardiovascular health.
