Contrary to
popular belief, fats are an important part of eating a healthy diet. The play
many vital roles in our bodies including providing energy. In fact, fat is your
muscle’s primary source of fuel when they are at rest and during light
activity. It also insulates your body and protects your organs, such as the
kidney, from injury. This nutrient is also necessary to help absorb vitamins A,
D, E and K. in addition, fat in a meal helps the food to digest more slowly,
maintaining satiation longer. It also adds flavor and texture to foods.
Now that you
know how important fat is to a balanced eating plan, you may be wondering why
it is left out of some weight loss programs. That is because fat is more
calorically, dense than carbohydrate and protein: one gram provides nine
calories, whereas carbohydrate and protein supply four calories per gram. A
tablespoon of fat (solid or oil) contains 120 calories.
Since fats
and oil are also sources of essential fatty acids, an important dietary
requirement, they provide energy and act as stores for energy.
In animals,
adipose tissue or fatty tissue is the body’s means of storing metabolic energy
over extended periods of time, the adipocytes (fat cell) store fate derived
from diet and from liver metabolism (glycogenolysis). Under energy stress these
cells may degrade their stored fat to supply fatty acids and also glycerol to
the circulation (gluconeoenesis). These metabolic activities are regulated by
several hormones such as insulin, glucagon and epinephrine.
Fats and oil
is responsible in digestion, absorption and transportation of some vitamins
which are vital in living organisms, such vitamins are soluble in fats
therefore the include; vitamin A(retinol), vitamin D(calciferol), vitamin E(tocopherol)
and vitamin K(phylloquinol)
Fats serve
as a useful buffer towards a host of diseases. When a particular substance
whether chemical of biotic reaches unsafe levels in the bloodstream, the body
can effectively dilute or at least maintain equilibrium of the offending
substance by storing it in new fat tissue. By this it helps to protect vital
organs until such time as the offending substance can be metabolize or removed
from the body by means of excretion, urination, accidental or intentional
bloodletting, sebum excretion and hair growth.
Fats play a
vital role in maintaining healthy skin and hair, insulating body organs against
shock, maintaining body temperature and promoting healthy cell functions.
Maintaining of healthy skin and hair is made possible because of one of the fat
soluble vitamin, (tocopherol). Talking of healthy skin, tocopherol which is a
wonderful antioxidant helps in trapping free radicals from the cell which is as
a result of metabolism and by so doing makes the skin supple and prevents
aging. No wonder most of our body creams and lotions today is made up of
vitamin E which is a fat soluble vitamin. Some pigment in our body such as the
melanin and keratin are as a result of vitamin E and these pigments are
responsible for healthy hair texture, hair colour, and for nail growth and palm
texture.
