Whether we should take fish oil supplements to enhance our memory is a concern for many people. On September 18, Professor Su Huanxing – the invited speaker from the Institute of Chinese Medical Sciences – gave an in-depth presentation about the structure, origin and functions of OMEGA-3, a major ingredient of fish oil. He also discussed the causes of cognitive dysfunctions and ways of preventing them. The talk was attended by 36 students.

The Alzheimer’s and vein-related diseases in the brain are the two major causes of memory loss and cognitive dysfunctions. OMEGA-3 is one type of unsaturated fatty acid, and DHA, an ingredient often found in milk powder for babies, is one type of OMEGA-3. The mainstream view of scientists is that OMEGA-3 helps relieve symptoms among patients who are at an initial stage of the Alzheimer’s disease or not severely affected by the disease. In addition, OMEGA-3 helps prevent vein-related disease of the brain and the heart, cancer and diabetes. It can help reduce inflammation and stabilize mood. In sum, OMEGA-3 is beneficial to humans in many ways.

OMEGA-3 can be absorbed only by eating, in particular, by eating deep sea fish which accumulate OMEGA-3 by eating seaweed. This is why the Eskimos – who often eat deep sea fish – seldom suffer from the Alzheimer’s disease.  Besides, green vegetables and nuts are also good OMEGA-3 supplements.

Professor Su reminded that there is only 30% of OMEGA-3 in fish oil. It may not be wise to take 30% of OMEGA-3 together with 70% of other unidentified fatty acids. He advised that we had better eat more food which is rich in OMEGA-3. After the talk, many students did follow up with various questions.

This talk is the second of a two-part seminar-talk series on the theme of “Reversing Memory Loss”. The first talk was delivered by Prof Lu Jiahong, also from the Institute of Chinese Medical Sciences, on September 11.
