Ground flax seed provides greater benefit than whole seed, as it releases the oils and nutrients within. Our Grainworks Organic Milled Flax is a convenient way to enjoy flax. Ground flax seeds can be added to smoothies and most recipes, delivering a range of nutrients and essential fatty acids. Flax seed and plant lignans Flax seeds are the richest source of plant lignans, a type of phytoestrogen. They occupy oestrogen receptors and reduce oestrogen's potentially harmful effects. Plant lignans appear to lower the risk of hormone-related cancers, particularly breast cancer. Flaxseeds are also rich in beneficial essential fatty acids, including alpha-linolenic acid, or ALA. ALA is used in hundreds of important functions in the body. Overall nutrition is equal between brown and golden flax seeds. Some studies show brown flax seeds to be slightly higher in alpha-linolenic fatty acid, but some chefs prefer golden flax seeds as their lighter colour does not darken baked good recipes. Flax seeds contain ample dietary fiber, are low in carbohydrates, and can be enjoyed in gluten-free diets. Tasty Tips and Storage Delicious in baked goods, smoothies, sprinkled on salads, yogurt and more. We recommend storing ground flax seed in the refrigerator after opening to keep essential oils at the peak of freshness.
