Omega-3 fatty acids are essential fatty acids: it is necessary to maintain good health, have a vital role in the growth and development of the human body and brain functioning; but it can not be synthesized by human beings or storage, only a day by dietary intake, supplement the body's needs. It maintains a balance of omega-3 and omega-6 fatty acids in the diet. Omega-6 and the growing imbalance of omega-3 fatty acid ratio, and further resulted in recent years, the incidence of heart disease, cancer, depression, chronic diseases, the rapid growth. There is evidence that the main reason leading to coronary heart disease is the intake of omega-6 fatty acids, too much omega-6 and omega-3 the ratio is too large. Food and agriculture organization and world health organization issued a statement. They recommended that people will consume linoleic acid and ± linolenic acid ratio from 10:1 to 5:1.

The researchers found that sub-linolenic acid containing in chia seed (an important omega-3 fatty acid) is very important to maintain a healthy heart and reduce cholesterol levels. It maintains artery patency and reduces the risk of cardiovascular disease and hypertension risk benefit. To this end, the heart association recommends a daily intake of linolenic acid.

It is extracted from fish, fish oil and has high omega-3 content, but its cholesterol content can not be ignored. Over-fishing and sea pollution, the world's fish storage capacity is declining, so the fish is no longer the best source of omega-3. Although the algae is cholesterol-free plant products, but mankind can not directly consume it; farmed seaweed or algae oil refinery will have a negative effect on the environment, but also unable to effectively provide mankind with omega-3 fatty acids.

Chia seed contains richest omega-3 fatty acid. As a pure natural material, it is used in functional foods, nutritional supplements, dietary supplements and cosmetics products by pharmaceutical raw materials suppliers.
