flaxseeds

Flaxseeds are small, flat seeds from the flax plant, Linum usitatissimum. They are used as a nutrient-rich food and can be consumed whole, ground, or as oil. Ground flaxseed is easier to digest and nutrient absorption is higher, while whole seeds may pass through the digestive system intact.

Nutritional profile and components: Flaxseeds provide omega-3 fatty acids, mainly alpha-linolenic acid (ALA), and contain both soluble and insoluble dietary fiber. They also include lignans, a class of phytoestrogens with antioxidant activity, as well as plant-based protein and minerals such as magnesium and manganese. In addition to fat and fiber, flaxseed contributes small amounts of vitamins and minerals.

Health considerations: Regular intake of flaxseed may support heart health by modestly improving lipid profiles and providing dietary fiber that supports digestion. Lignans and other phytochemicals may offer antioxidant benefits. Flaxseed should not be considered a medicine or sole treatment for health conditions. Because it contains phytoestrogens and can affect clotting, individuals taking anticoagulant or antiplatelet medications, or those with hormone-sensitive conditions, should consult a healthcare provider before substantial or long-term use. Start with small amounts and increase gradually with adequate fluids to avoid digestive discomfort.

Culinary uses and preparation: Flaxseed can be added to cereal, yogurt, smoothies, and baked goods. A common vegan baking substitute uses ground flaxseed mixed with water to form a gel that can replace eggs. Flaxseed oil provides fats but little fiber and should be kept refrigerated and used without high-heat cooking to preserve quality.

Storage and safety: Whole flaxseeds have a relatively long shelf life in a cool, dark place. Ground flaxseed is prone to rancidity and is best stored in a sealed container in a refrigerator, where it should be used within one to two months.
