Decipher the Ancient Myth

While playing with my App, Nutrition Tracker, I gradually understand some old Chinese sayings, like "the more fish one has, the bigger one's brain is". Omega 3 is the required nutrition to have a healthy brain. The critical part in Omega 3 is DHA that is hard to be synthesized by human body. The natural food that contains high DHA is mostly fish. Although Salmon has been more popular than cod. According to the USAD food nutirion database and the calculation from Nutrition Tracker, for an adult, if one has 8 ounces of cooked salmon weekly, one doesn't need to take any supplement for Omega 3 at all. In another words, if one has two or three big meals with fish weekly, one will have enough Omega 3 to have a healthy brain. This amazingly explains the old Chinese myth I didn't understand before. This is a great book about how to cook fish: Fish: Fish: Complete Guide to Buying and Cooking.
