>>212040886 (OP)If you are concerned, then I'll explain it's more than OK and the reasons why.
Fish lipids (especially ones in bluebacks ) are mainly composed of unsaturated fatty acids such as DHA and EPA, and these components have the effect of lowering triglycerides and cholesterol in the blood.
It is also expected to reduce the risk of arteriosclerosis, heart disease, and cerebrovascular disease.
Plus, DHA is good for your brain as it is a major component of the brain's nerve cells and is an important nutrient for maintaining and improving brain function.
It's fairly OK to have it compared to have whatever a mammals meat instead.
