Lignans:

  • Secoisolariciresinol: This is one of the main lignans found in flaxseeds and sesame seeds. Lignans are known for their ability to modulate hormone levels, particularly oestrogen. They have been studied for their potential to reduce the risk of hormone-related cancers, such as breast and prostate cancer. Additionally, lignans have antioxidant properties that help protect cells from damage.

  • Sources: Flaxseeds, sesame seeds, whole grains, and cruciferous vegetables like broccoli and Brussels sprouts.

Health benefits:

  • Heart health: Both stilbenes and lignans support cardiovascular health by reducing inflammation, lowering blood pressure, and improving cholesterol levels.

  • Hormone balance: Lignans can help balance hormone levels, reducing the risk of hormone-related cancers.

  • Longevity: Resveratrol has been linked to longer lifespans due to its anti-ageing effects and ability to mimic calorie restriction.

  • Antioxidant protection: These compounds help protect cells from oxidative damage, supporting overall health.
