Nutrition composition

Fat

Recommend low in saturated fats diet. COR/LOE: R/1 +  + Daily saturated fat: men ≤ 30 g, women ≤ 20 g COR/LOE: ✔/4

 

Limit total fat lower than 30% of energy intake, saturated fat to 7%, and omega-6 PUFA to 10%. Restrict trans-fat less than 1%. COR/LOE: GPP/2 + 

Nutrition composition

Trans fatty acid

Minimize trans unsaturated fatty acids, especially from processed foods. Reduce red meat to 350-500 g weekly, and limit processed meat. COR/LOE: I/A

Keep trans fatty acid (TFA) below 1% and minimize high-fat processed meat and bakery products. Reduce partially hydrogenated fats.
