Dietary fibre · Alpha-linolenic acid · Lignans · Protein and micronutrients
Flaxseed is a nutrient-dense seed that has been widely studied for its effects on cardiovascular health, metabolic function, and inflammation. It is one of the richest plant-based sources of both dietary fibre and alpha-linolenic acid (ALA), a type of omega-3 fatty acid.
Flaxseed has attracted significant scientific interest due to its combination of fibre, healthy fats, and unique lignans, which are bioactive compounds associated with antioxidant and hormonal effects. These properties make it particularly relevant in a longevity-focused dietary pattern.
Flaxseed contains a diverse range of bioactive components:
- Dietary fibre (both soluble and insoluble) — supporting gut health and metabolic regulation
- Alpha-linolenic acid (ALA) — a plant-based omega-3 fatty acid
- Lignans (e.g. secoisolariciresinol diglucoside, SDG) — associated with antioxidant and hormonal effects
- Protein and micronutrients — contributing to overall nutritional value
This combination makes flaxseed one of the most nutritionally dense plant ingredients available.
