Summary: dietary strategies to reduce total serum cholesterol: Milk, cream, cheese, beef, pork, chicken, shrimp, lobster, eggs (yolk) Decrease total fat intake (especially saturated and trans) Increase soluble fibre intake (citrus fruit, oatmeal, legumes- inside) Fish oils: epa (20:5n-3) and dha (22:6n-3: originate from phytoplankton, then is eaten by small fish then bigger fish and so on, 1970s- greenland inuit, increased intake of fish and marine animals (whale. Where did interest in fish oils originate? blubber, seal meat) Blood clotting ability/response somewhat decreased; much less likely to develop thrombosis. Epa has more beneficial effects on the heart. Alpha linolenic acid can be converted to epa by the body- but it isn"t very efficient. Epa can then be converted to dha- also not very efficient (1-3% conversion) Reduces the degree of platelet reactivity (clotting potential) What about dha? with a lack of dha) Essential fatty acids: main benefits are for brain and retinal development (only works for infants.
