Flax seeds are an excellent source of fiber, omega-3 fatty acids and lignans - phytoestrogens that are broken down into useful antioxidants.
Flaxseed is an excellent breakfast supplement that supports the healthy functions of the brain, eyes, heart and nervous system. Seeds are an excellent plant source of fats, including omega-3 saturated fatty acids. They play a role in suppressing inflammatory processes and lowering blood cholesterol levels. There is also an optimal amount of dietary fiber, which slows down digestion, quickly satisfies hunger, and facilitates peristalsis.
Two tablespoons of flaxseed contribute 15-25% of the recommended daily intake of fiber. Between 20% and 40% of them are in the form of soluble fiber, and most (60-80%) are insoluble, mainly composed of cellulose and lignin. Soluble, mainly composed of exopolysaccharides are involved in the regulation of blood sugar and cholesterol, and also - serves to feed the beneficial bacteria in the gastrointestinal tract, improving their function and digestion in general.
Flax seeds are the richest known source of lignans - plant chemicals, from the group of phytoestrogens. They mimic the structure of the human sex hormone estrogen and act as powerful antioxidants. This should not be a concern - lignans are also found in cereals, peaches, strawberries, and green leafy plants.
Lignans do not lead to disturbances in the hormonal balance of the human body, intestinal bacteria metabolize them to enterodiol and enterolactone - useful, antioxidant compounds that protect the cardiovascular system from free radical damage and increase protection against cancer.
About 40% of flaxseed is a fat known as " linseed oil ". Among all types of vegetable oils, it is the richest in alpha-linolenic acid. It also contains proteins, lecithin, pantothenic and folic acid, vitamins B 1, B 2, B 6, and E.
14 grams (two tablespoons) of raw flaxseed contain 75 calories, and compared to the required daily amount (in percent), it contains: 133% omega-3 saturated acids; 19% vitamin B1; 19% honey; 18% manganese; 15% fiber; 14% magnesium; 13% phosphorus and 6% selenium.
