Dietitians often recommend eating poached salmon, rather than "red meat," to lower cholesterol. Experimenters have measured the toxic oxidized cholesterol in different foods prepared in a variety of ways. Steaming salmon produced several times as much oxidized cholesterol as frying it, because of the longer cooking time that allowed the polyunsaturated fatty acids to break down, producing toxins such as acrolein and free radicals that oxidize the cholesterol and other components of the fish. The toxic cholesterol content of the steamed salmon was much higher than that of beef cooked at a high temperature.
