Chia Seeds

Chia seeds are extraordinarily fiber-rich — 34g per 100g, with most of it soluble. They absorb up to 10× their weight in water, which slows digestion and supports satiety. They also deliver plant-based ALA omega-3s, calcium, and magnesium. Soak before eating for the best digestive tolerance.

Flaxseed (ground)

Ground flaxseed is the richest plant source of ALA omega-3 fatty acids and lignans — phytoestrogens linked in studies to hormone balance and reduced LDL cholesterol. Whole flaxseed passes through largely undigested, so grinding (or buying pre-ground) is essential to unlock its nutrients.
