Lignans

Lignans are a type of polyphenol found in a variety of plant foods. They are known for their antioxidant properties and potential health benefits, particularly in relation to heart disease, cancer, and hormonal balance.

Overview

Lignans are one of the major classes of phytoestrogens, which are estrogen-like chemicals and also act as antioxidants. The other classes of phytoestrogens are isoflavones and coumestans. Lignans are often categorized as a type of fiber because they bind to fiber in the diet and are then converted into enterolignans by gut bacteria.

Sources

Lignans are found in a wide variety of plant foods. The richest sources are flaxseeds and sesame seeds, which contain up to 800 times more lignans than other foods. Other good sources include grains, legumes, fruits, and vegetables.

Health Benefits

Research has suggested that lignans may have several health benefits. They have been linked to a reduced risk of heart disease and certain types of cancer, particularly breast cancer and prostate cancer. Lignans may also help to balance hormones, particularly in post-menopausal women.
