Extract

Consumption of milk and milk products contributes 14-15% of total dietary fat intake by adults in Great Britain, and provides 23-25% of total saturated fat intake. The relationship between dietary fat intake and incidence of coronary heart disease is well established and current recommendations are that total fat consumption should not exceed 35% of daily food energy intake and that saturated fat intake should not exceed 11% of daily food energy. Studies have shown that different saturated (SFA) fatty acids can have different effects on plasma lipoprotein cholesterol levels and that replacing SFA and trans (TFA) fatty acids with cis-unsaturated (USFA) fatty acids has a favourable effect on total and LDL-cholesterol levels (Zock, 2006). The present study aimed to apply dietary modification of the dairy cow diet to produce milk fat with a healthier fatty acid profile to meet human dietary recommendations.
