Flaxseed is rich in more than 50% α -linolenic acid, which is many times higher than walnut. α -linolenic acid is very effective in reducing coronary artery disease, hypertension and body tissue inflammation. Helps to fight breast cancer and rheumatoid arthritis, increase intestinal peristalsis, lower cholesterol, prevent cardiovascular diseases, prevent constipation and immune system dysfunction.
α -linolenic acid is a kind of nutrient, which has a good effect on human brain and neurocardiovascular system. α -linolenic acid provides energy for the brain, which can relieve fatigue and stress, promote physical recovery and effectively reduce the "sub-health" situation.
DHA is a metabolite of α -linolenic acid, which is directly related to the growth and development of nerve cells in the brain and retina. Pregnant women should take enough α -linolenic acid every day to meet the needs of baby's intelligence and vision development. It can also make the baby's brain smarter and eyes brighter.
Tea seed oil
The fatty acids of tea seed oil extracted from tea seeds include oleic acid, linoleic acid, palmitic acid, stearic acid, linolenic acid and myristic acid. Linoleic acid and linolenic acid are indispensable for maintaining the growth of human skin and hair, and can prevent arteriosclerosis. Unsaturated fatty acids account for more than 85% in tea seed oil, which is rich in tea polyphenols, vitamin E and carotenoids.
Tea seed oil has antioxidant capacity, which can lower blood pressure, reduce blood lipid and inhibit arteriosclerosis. The nutritional value of tea seed oil is equivalent to that of olive oil, and it is a high-grade edible oil.
safflower oil
Safflower oil has the highest linoleic acid content in known vegetable oil and is a good source of linoleic acid, so it has the largest iodine value and high nutritional value in semi-drying oil. Mixing 30% safflower oil with 70% rice bran oil can obviously reduce cholesterol in human serum, so it is called "healthy (healthy food) nutritional oil". Experiments show that safflower oil can not only significantly reduce serum cholesterol and triglyceride in some animals, but also significantly reduce the occurrence of atherosclerosis. The content of natural linoleic acid in safflower seed oil is 84.2%, with an average of more than 75%.
sunflower seed oil
Sunflower seed oil is rich in vitamin E and unsaturated fat "linoleic acid" which is necessary for human body, and the content is as high as 58%-69%. The digestibility of sunflower seed oil is 96.5%, which is convenient for human body to absorb. Usually, the nutritional value of 500 grams of sunflower seed oil is equivalent to that of 2000 grams of common salad oil.
The smoke point of sunflower seed oil is high and stable, and the temperature can reach 232℃ when refining. At the high temperature of 1 10℃, the oil quality can remain unchanged for 25 hours, and it is an ideal frying edible oil with high temperature resistance.
Sunflower seed oil produced in cold areas contains about 15% oleic acid and about 70% linoleic acid. Sunflower seed oil produced in warm areas contains about 65% oleic acid and 20% linoleic acid. Linoleic acid can significantly lower cholesterol, prevent arteriosclerosis and coronary heart disease.
