Flaxseed, unlike other grains, does not contain gluten naturally. It would carry gluten only if it came into contact with gluten-containing grains, additives or preservatives through cross-contamination during growing, processing, manufacturing or shared equipment.
The seed of the flax plant derives its health benefits from high dietary fiber, protein, numerous micronutrients, omega-3 fatty acids and phytochemicals called lignans. Flaxseed's micronutrient content includes vitamins B1, B2, B3, B5, B6, B9, C, calcium, iron, magnesium, phosphorus, potassium and zinc. Its high fiber content helps with constipation and digestive problems. According to some studies, consuming whole or ground flaxseed may help lower total cholesterol count and low-density lipoprotein cholesterol levels.
