This topic reminds me of an interesting Chinese saying that goes if you eating the same animal organs can be better for your own organs. So,amny people like to eat pig or cow livers to help their own liver to be better. Doesn't it sounds weired? In fact, Chinese people are really good at cooking a variety of dishes with animal organs. When we try to cook some dish with amimal brains, the pigs' is the easiest one to get. But many people don't like eating pig brains, because they think that pigs are not that clever. So, what can be used to replace the pigs' brains? A special thing usually comes into our minds , guess what? It's definitely the wallnuts. The inside part of a wallnut pretty looks like a man's brain and it's very nutritious, so we like eating wallnuts to hope that we will get more clever. As a consequence, few people become more clever after even eating too much wallnuts. Maybe DHA can be good for tots' brains, but in my opinion, only using our brain as much as possible can keep us clever.
