What phytochemical is known to lower elevated cholesterol levels?

Isoflavones are phytochemicals primarily found in soy products and certain other legumes. They have a structure similar to estrogen, which allows them to potentially interact with estrogen receptors in the body. Research suggests that isoflavones can help lower levels of LDL cholesterol, often referred to as "bad cholesterol." This reduction can be beneficial for cardiovascular health, particularly in individuals with elevated cholesterol levels. The mechanism through which isoflavones exert this effect includes modulation of cholesterol synthesis and metabolism, as well as influencing the absorption of dietary cholesterol in the intestines.

While other phytochemicals, such as flavonoids and specific compounds like quercetin, have health benefits and may contribute to heart health, the specific action of lowering cholesterol levels has been more firmly attributed to isoflavones. Carotenoids, primarily known for their antioxidant properties, focus more on supporting overall health rather than specifically targeting cholesterol reduction.
