Saturated and unsaturated fats are different kinds of fat, found in different amounts in different foods. While full fat dairy products and meats (as well as many processed foods like cakes and biscuits) are high in “bad” saturated fat, great sources of “good” unsaturated fat include nuts, seeds, and vegetable oils.
One of the most relevant aspects of the difference between these types of fat is in the impact they have on the body. So which kind of fat is better for you?
Saturated vs. unsaturated fatWhile it’s not practical to eliminate saturated fat in your diet entirely, as it is present (in small amounts) in many foods, replacing saturated fats with unsaturated fats in the diet has been shown to lower blood cholesterol – one of the risk factors in the development of heart disease.
So paying attention to the amount of saturated fat vs. unsaturated fat in your diet, and opting for unsaturated options where possible, is a positive step for heart health.
Thus its concluded that vegitable oils are good than diary products and meat.
Now consider the case of oil. The mostly used oil is coconut oil and it says that.
Many in the coconut oil business promote it as the "good" saturated fat. But "this is a case where facts have been twisted into fiction," states Dr. Jay Kenney, Educator and Nutrition Research Specialist at Pritikin.
All oils are a mixture of saturated, monounsaturated, and polyunsaturated fatty acids, though each oil is usually called by the name of the fatty acid that is most abundant. The artery-clogging – and therefore most damaging – fatty acid is saturated fat. The fat in coconut oil is 92% saturated fat.
What gets tricky is that there are different kinds of saturated fats. Some are long-chain (they have 12 or more carbon atoms), and some are medium-chain (fewer than 12 carbon atoms). These various saturated fats do not have the same impact on LDL (bad) cholesterol levels in the blood. One long-chain saturated fat, stearic acid, has little impact on LDL cholesterol. Stearic acid is the most common saturated fat in chocolate, which is why chocolate or cocoa butter raises LDL only about one-quarter as much as butter, even though both are about 60% saturated fat.
But other long-chain saturated fatty acids, like the ones that make up most of the saturated fat in coconut, palm kernel, and palm oils (known as tropical oils), do in fact raise LDL cholesterol considerably. These saturated fats are called palmitic, myristic, and lauric acids. They also make up most of the saturated fatty acids in meat, poultry, and dairy fats like milk, butter, and cheese.
This is the reason why the dietician prefereed to consume less oil. For Children in growing age (teenagers) needs more calories and fats are those food items contains more calories. Fats are good for healsth in case you burn them up properly by doing proper exercise any how it is not good for adults as they have lower metabolism than teenagers.
Hope you got it
