While prawns contain higher than average amounts of cholesterol, they do not lead to higher cholesterol levels in the body due to their healthy fat profile. This is because they contain almost three times more Omega 3 Fatty Acid than they do Omega 6 Fatty Acid. Studies have shown that foods with high amounts of Omega 3 are associated with a reduced risk of heart attacks and lower blood pressure. In fact, the cholesterol contained in prawns is vital for a healthy diet.
