A medical practitioner, Dr Arikawe Adeolu, has warned against the excessive consumption of catfish, saying it could increase the chances of developing cardiovascular diseases.
Adeolu, a practitioner at the Federal Medical Centre, Jabi, Abuja, gave the warning in an interview with the News Agency of Nigeria (NAN).
He said that catfish contains omega-6 fatty acids, which could increase the level of inflammation in the body.
He added that inflammation was the underlying cause of cardiovascular diseases, certain cancers and diabetes.
He said that although catfish also contained omega-3 fatty acids, which has a lot of health benefits, the ratio of omega-6 was far greater than omega-3 fatty acids.
Adeolu said that this made it necessary for the fish to be consumed in moderation to prevent health complications.
“Catfish is rich in two fatty acids – omega-3 fatty acids and the omega-6 fatty acids.
“The omega-3 fatty acids help reduce the concentration of bad cholesterol in the blood stream and increase the concentration of good cholesterol in the blood stream.
“It also helps protect the heart and the cardiovascular system from any form of disease, prevents inflammation within the body and helps reduce the quantity or concentration of inflammatory substances in the body.
“The underlining basis for most cardiovascular diseases, diabetes, cancer, Alzheimer disease and many other diseases that we know today, is chronic inflammation, which signifies a long standing inflammation in the body.
“This is where the catfish controversy comes in. A lot of reports have advised against eating it and this is because although it contains omega-3 fatty acids, which have many health benefits, it contains more omega-6 fatty acids.
“Omega-6 fatty acids are pro-inflammatory in the sense that they increase the level of inflammation within the body and make one more predisposed to any kind of disease.
“When catfish features a lot in your diet, you consume more omega-6 fatty acids in your diet than the protective omega-3 fatty acids.
“Therefore, you are more predisposed to diseases if you consume a lot of catfish.
“The optimal ratio of omega-6 fatty acids to omega-3 fatty acids is supposed to be four to one, but because the catfish is reared artificially and is fed with synthesised food, the ratio can be up to ten to one,’’ he said.
Adeolu also said even though there were a lot of controversies surrounding the consumption of catfish, it still held some advantages over most fishes consumed today.
He said catfish is a good source of protein, rich in essential amino acids needed to build muscles, bones and different tissues in the body.
He explained that catfish contains a moderate amount of calories per serving or per gram, hence, was an ideal choice for those watching their body weight.
According to him, catfish is rich in phosphorus and magnesium, which are essential micro-nutrients that play a significant role in a lot of biochemical processes in the body.
“Catfish has a very low amount of mercury, which is very toxic to the human body and can when consumed in large quantities, damage the nervous system,“ Adeolu said.
