Alsi seed is another name for flaxseed, which is a small oilseed that contains omega-3 fats, fiber, and other plant compounds. Flaxseeds are a good source of dietary fiber and omega-3 fatty acids, including alpha-linolenic acid (ALA), which is an essential fatty acid that the body cannot produce. Eating flax seeds can help improve digestion and reduce the risk of heart disease, type 2 diabetes, and cancer. Flax seeds can be consumed in various ways, such as mixing them into smoothies, adding them to pancake batter, homemade veggie burgers, and even overnight oats.
