With the development of society, the idea of the healthy diet is rooted in the hearts of the people constantly, fat and oil food may be said to a lot of persons who value the size that hang back, the standard of the healthy diet seems to be defined as the low lipoprotein of few oil by most TV programmes and books, newspapers and magazines too. True, it has already with obesity become problems deeply concerned of public Ministry of Health in a lot of countries that the ones that increase rapidly are overweight, but if fat or take in fat, will cause question while being too much, fat fine their indispensable to rarely known by the people to human body even then. The latest magazine of " science in future " of France writes articles to point out, three major life key elements that it is essential that fat and protein, candy form organism, in a sense, without fat, there is no lives.

As to numerous animals, it is for spending severe winter and long deficient stage of food that its memory of body stores the fat, in a quite long historical period, the mankind is like other animals too, it is abundant and most suitable for storing the internal fooding to look for heat actively. And the most abundant food of heat certainly should be the fat, the human ancestor in prehistoric period lives, the fat absorbed on average every day is too quantitative to exceed 25%, but the fat consumption exceeded 45% on human average day at present.

The first leading use of the fat lies in making up in the cell solute area " Bubble " ,This characteristic is exactly the condition that intravital cells exist, this so-called " bubble " It is not other things, it is exactly cholesterol of different types. This kind of plasma membrane isolating internal and external cells is organized, it is a kind of greasy, soft, impermeable, plastic membrane, this layer of membrane can hold countless albumens, these albumens make the molecule enter or discharge, thus make cells demonstrate one's own characteristic.

Another function of the fat is that the energy store the storehouse, oil heat value is extremely abundant, and can store in the body endlessly. The scientist estimates a person's quantitative demand of oil of every day should be 1.5 grams for per kilogram of weight, convert like this, as to a person 70 kilograms in weight, the oil needed every day should be 105 grams.

The most common oil is three sour glycerine lipoprotein, 95% of the fat belongs to three sour glycerine lipoprotein in the food, this oil is made up of three kinds of oil acid, some of them's essential sour human body of oil can not be formated. Obviously, the most famous kind of fat calls cholesterol, it has been criticized as is the arch-criminal who causes cardiovascular vessel disease for a long time, but say from the scientific angle, this criticism is actually wrong partly, because over 3/4 cholesterol is formated in the liver, only less than 1/4 cholesterol comes from the food. The cholesterol content in ox's brain, egg yolk is very high, but cholesterol content in chicken, beef, fish is few, cholesterol is playing prominent early warning function in the bone calcification, steroids, acid bile including sex hormone, play an important protection role in the cell membrane too.

Scientific experimentation indicates, cholesterol is too high or may bring the serious consequence to pass low in proportion, some people will also divide cholesterol into " Good cholesterol " Or " bad cholesterol " ,In fact, cholesterol essence is the same, that only changed is only that because the necessary carriers while moving are different and form so-called " good cholesterol " With " bad cholesterol " . Cholesterol can't be melted in the blood, so need appropriate means of transportation, this means of transportation is usually said lipoprotein.

There are four kinds of lipoprotein altogether, can be distinguished through the weight: The first kind transports lipoprotein of cholesterol to call lipoprotein of high density, its function is just like " garbage truck " ,Responsible for tidying up useless cholesterol " The dustbin " ,That is to say to deal with the liver, form the so-called " good cholesterol " after dealing with ,Can dissolve blood atherosclerosis.

The second kind of tools which transport cholesterol are lipoprotein of low density, its function is to responsible for delivering cholesterol just made out to every place of the body, but it is getting more perfect in course at task since it finish,it can pairs of " the goods " that be carried Omit into the artery, such a result is to result in forming the blood and circulating and stopping up more or less finally, this kind of omission is named to cholesterol into the artery " Bad cholesterol " . As everyone knows, " bad cholesterol " Proportion can't getting higher too,otherwise cause by cardiovascular vessel disease.

The transport tools of other two kinds of cholesterol, one will retrieve the fat from food in the stomach, then send them to the other tissues of the body; The last kind is more mysterious, it is " lipoprotein of ultralow density " ,About such mysterious lipoprotein, a lot of study and wait for a scientist to finish.

Can find out, cholesterol and even the fat are not harmful to having no profit to the human body, so long as keep on a diet according to the scientific method, it is not doomsday to take in the fat in right amount to those persons who like to be beautiful.
