Fish oil capsules are highly processed food. People lived for millions of years on natural food. Processed food has only existed in the industrial age. Advertising (propaganda) has created the demand for the product, not need. Heart disease is a by-product of the industrial age.

I commend your attempts to make yourself healthy, you are the only one who can make you healthy. Food grows, it does not come from a factory. Eat everything as close to the way it grew as possible. Never put anything in your mouth from a fast-food joint or a convenience store. Avoid hydrogenated fat, high fructose corn syrup and refined grains, they are poison, really. Healthy people do not take pharmaceuticals and pharmaceuticals do not make people healthy.
