Phytosterols Against Cancer

Among the most studied natural compounds affecting reproductive hormones in the body are the phytosterols.

They are most concentrated in nuts and seeds of plants and are present in the oils expressed from these.

Pumpkin, sesame, flax, and sunflower seeds and oils are high in phytosterols, and cereal grains and legumes such as rice, wheat germ, soy, peas, and other beans also contain phytosterols.

Processing and hydrogenating the oils expressed from these foods destroy the phytosterols, and ingesting margarine produced from these otherwise healthy oils does not possess the same hormonal benefits as does eating whole nuts and seeds or consuming high-quality cold-expressed natural oils.

In fact, phytosterols are common in plants and everyday foods.

Taraxacum (Dandelion), Calendula (Marigold), and many other herbs contain phytosterols, as do most vegetables such as carrots and broccoli in at least trace amounts.

Phytosterols in whole grains, nuts, legumes, and vegetables may contribute to the anticancer effects of these foods when consumed over a lifetime.

Chocolate (Theobroma cacao) contains phytosterols, and researchers reported anticancer effects from eating dark chocolate (70% or greater levels of Cacao), including antimetastatic influences on prostate cancer. 

Two of the most researched and most popular herbs for the treatment of prostatic disease are nettle root and saw palmetto, both of which contain significant amounts of phytosterols.
