Total fat content of traditional diets varies from 30 % to 80 % but only about 4 % of calories come from polyunsaturated oils naturally occurring in grains, pulses, nuts, fish, animal fats and vegetables. (westonaprice.org)
Darker fleshed fish such as herring, salmon, mackerel and bluefish generally have a higher total fat content than leaner fish species with lighter colored flesh such as cod, flounder, and pollock. (seafoodhealthfacts.org)
Although a high - MUFA diet that exceeds 30 % of calories from fat is not a Step 1 or Step 2 diet because it does not meet the criteria for total fat content, it nonetheless is another viable option for managing risk factors in the prevention and treatment of CHD. (circ.ahajournals.org)
