Answer
Saturated fats derive mainly from animal sources.
Some food sources are meat, egg yolk, dairy products. Some plant sources are palm oil and coconut oil-- used for cooking (frying) or consumed as components of non-dietary creamers. Hydrogenated oils and vegetable shortening also contain saturated fats.
The common sources of unsaturated fats are vegetable oils, nuts and seeds, fatty fish (salmon, mackerel, herring), avocado, avocado oil, olives, olive oil, peanut butter, peanut oil, and sunflower oil.
Essential fatty acids are linoleic acid, arachidonic acid and alpha-linolenic acid.
Sources of essential fatty acids include, vegetable oils in mayonnaise, salad dressings, margarine, whole grains, vegetables, nuts, safflower oil, flaxseed oil, and walnuts/oil
Dietary sources of Cholesterol:
The richest source of cholesterol is egg yolk. Other sources include , milk products, shellfish, and meats. The richest meat sources are organ meats-- kidneys, liver, brains --but other mammalian meats also supply cholesterol. Plant (vegetable) foods do not contain cholesterol. Some contain phytosterol, but this sterol is not absorbed by the intestines.
Work Step by Step
Palm oil and some other plant sources of saturated fats can promote the synthesis of cholesterol in the body.
Fats have essential physiological functions in the body. But the consumption of too much fats-- unsaturated and saturated --is not good for health. Excessive of fats in the body increases risks of developing diabetes mellitus (Type II), cardiovascular disease and breast cancer.
