=== Fats ===

Fats supply concentrated energy, carry the fat-soluble vitamins A, D, E, and K, and provide essential fatty acids.

* '''Saturated fat''' (animal fat, butter, coconut and palm oil) raises LDL cholesterol. Limit to less than 10 percent of calories, and less than 6 percent for patients with cardiovascular disease.
* '''Trans fat''' (partially hydrogenated oils) raises LDL and lowers HDL. Intake should be as close to zero as possible.
* '''Unsaturated fats''' are preferred. Monounsaturated fat comes from olive oil, canola oil, avocado, and nuts. Polyunsaturated fat includes the omega-3 fatty acids found in salmon, mackerel, sardines, walnuts, and flaxseed, which lower triglycerides.
* Dietary cholesterol comes only from animal sources. Plant foods contain no cholesterol.
