3 phytosterols
Beta-sitosterol is the most common plant sterol, and your gut keeps under 1% of it, against 50% to 60% of the cholesterol you eat. Here is what 27 studies show for LDL cholesterol and prostate symptoms, which foods have it, and who should avoid it.
Campesterol is the plant sterol that researchers measure in blood to estimate how much cholesterol the gut absorbs. Here is what 23 studies show about heart disease, which foods have the most, and how safe sterol products are.
Stigmasterol is a plant sterol that looks like cholesterol, and in the 1940s chemists turned the soybean version into the hormone progesterone. Here is what 15 studies show about how little the body absorbs, heart and cancer risk, which foods have it, and safety.
