Macro partitioning

Higher plasma concentrations of even-chain saturated fatty acids (specifically stearic and palmitic acid) are positively associated with an increased risk of incident coronary heart disease, whereas higher plasma concentrations of omega-6 polyunsaturated fatty acids (specifically linoleic acid) are inversely associated with CHD risk.

Focus on the quality of your fats rather than just total fat intake. High levels of saturated fats (like stearic and palmitic acid found in animal products) are linked to higher heart disease risk, while omega-6 polyunsaturated fats (like linoleic acid found in vegetable oils and nuts) are linked to lower risk. Replacing saturated fats with unsaturated fats appears to be a beneficial strategy for heart health.
