According to a new study by researchers at the University of Eastern Finland, increased intake of fatty fish (three to four times in a week) can boost good cholesterol levels and provide protection against heart diseases. Study participants who increased their intake of fatty fish (without added butter or cream) showed positive changes in lipid metabolism. They had raised levels of large high density lipoprotein (HDL) or good cholesterol particles in their blood compared to those who ate fish less frequently. Fatty fish like salmon, mackerel and sardines are high in omega-3 fatty acids and low in saturated fats. And omega-3 fats are beneficial for heart in several ways. They are known to prevent arrhythmia , reduce the risk of blood clotting, decrease the levels of triglycerides and reduce blood pressure. These positive effects are seen only with the consumption of fatty fish. Study researchers doubt whether other low-fat fish like zander and perch would have shown a similar kind of effect on the levels of cholesterol . Not just protection against heart diseases , eating fatty fish has been associated with an array of health benefits
