Question

如题所述

Answer 1

Fats play a vital role in maintaining healthy skin and hair
insulating body against shock
maintaining body temperature
and promoting healthy cell function. Fats serve as energy stores for the body. Fats are broken down in the body to release glycerol and free fatty acids. The glycerol can be converted to glucose by the liver and thus used as a source of energy. Fats also serves as a useful buffer towards a host of diseases. When a particular substance
whether chemical or biotic -- reaches unsafe levels in the bloodstream
the body can effectively dilute -- or at least maintain equilibrium of -- the offending substances by storing it in new fat tissue. This helps to protect vital
until such time as the offending substances can be metabolized and/or removed from the body by such me as excretion
urination
accidental or intentional bloodletting
sebum excretion
and hair growth. Some fatty acids are essential nutrients
meaning that they can't be produced in the body from other pounds and need to be consumed in *** all amounts. All other fats required by the body are non-essential and can be produced in the body from other pounds. Vitamins A
D
E
and K are fat-soluble
meaning they can only be digested
absorbed
and trported in conjunction with fats. Fats are sources of essential fatty acids
an important dietary requirement. If you are also interested in the information of bad fats

polyunsaturated and monounsaturated fats are tested quite differently. Fat also serves as a useful buffer towards a host of diseases. When a particular substance
