lignani

Lignans are a diverse group of polyphenolic compounds found in plants. They are biosynthesized from the amino acid phenylalanine and are present in various plant tissues, including seeds, fruits, and grains. Lignans play a role in plant defense mechanisms and structural integrity.

In human nutrition, lignans are notable for their potential health benefits. They are often found in foods such as flaxseeds, sesame seeds, whole grains, fruits, and vegetables. Once consumed, gut bacteria can metabolize certain lignans into enterolignans, which are thought to be responsible for many of their biological activities.

Research has explored the association between lignan intake and various health outcomes. Some studies suggest that lignans may possess antioxidant and anti-inflammatory properties. There is also ongoing investigation into their potential role in hormone balance and their impact on certain types of cancer, though more research is needed to establish definitive conclusions. The bioavailability and effectiveness of lignans can vary depending on the source and individual metabolism.
