Jakarta, An article that is quite viral on the internet says that catfish contains 3,000 cancer cells. Many argue, because in fact catfish actually contains many important nutrients. The nutritional content in catfish includes protein and omega three fatty acids, which are said to be equivalent to salmon. Given the large number of nutrients in catfish, the relationship between catfish and the risk of cancer is questionable. It's different if you use oil that is used many times, it can trigger cancer. But it's not from fish but from the oil, said Dr. Dradjat R Suardi, SpB(K)Onk, a cancer expert from the Indonesian Oncology Association when contacted by detikHealth, Friday (23/10/2015). The relationship between repeated use of oil and the risk of cancer itself is debatable. During this time, trans oils that are formed due to repeated heating are more often associated with the risk of heart and blood vessel disease. The allegation that catfish can trigger cancer is based on the nature of the fish that likes to consume waste. Also because it is able to survive in muddy and polluted waters, it is thought that many carcinogenic toxins are contained in this fish. Currently there is no research that states that eating catfish can trigger cancer, said Dr. Dradjat.
