Plant sterols and stanols are compounds structurally similar to cholesterol, found naturally in plants. When consumed, they compete with cholesterol for absorption in the gut, effectively reducing the amount of dietary and biliary cholesterol absorbed into the bloodstream. This leads to a measurable decrease in LDL (low-density lipoprotein) cholesterol, a primary modifiable risk factor for atherosclerosis and cardiovascular disease, thereby supporting long-term cardiovascular healthspan.
Verdict
Effective, safe LDL reduction for cardiovascular healthspan; monitor fat-soluble vitamins.
