diet. Technically, the meaning of nutrition is that it is an
investment. If you put the right things in your body this can help
promote physical fitness and prevent illness.
Good nutrition can help prevent disease and promote health. There are
six types of nutrients that the body needs to accomplish this. This
includes carbohydrates, protein, carbohydrates, fibers fat, vitamins
and minerals, and water.
Proteins contain amino acids, which are the building blocks of body
tissue. All together there are twenty amino acids that are considered
to be the building blocks of protein. All twenty of these amino acids
must be working together for the body to function properly. Twelve of
these amino acids are made in the body but the others have to be
gotten through food sources. Foods from animal sources such as milk or
eggs are good sources of these amino acids.
Contrary to what you might think about the meaning of nutrition, fat
is needed to supply energy transport nutrients. There are many
classifications of fat but the two kinds that are healthiest for you
are omega-3 and omega-6 acids. These are called essential fatty acids.
The omega-3 type can be obtained from canola oil, flaxseed oil or fish
oil. You can get the omega-6 type from evening primrose and black
currant seed oil. Usually people are deficient in the omega 3 fats.
Carbohydrates are also a necessary component of a total daily intake.
There are two types of carbohydrates – simple ones such as sugar and
honey and complex carbs, which consist of grains, beans, potatoes or
peas. Complex carbohydrates are preferred because they have fewer
calories per gram compared to fat.
Fiber is the material that makes up the tissues and support structures
of plants. The body needs it for elimination and digestion. There are
two types of fiber – soluble and insoluble. Insoluble does not
dissolve in water. Dietary fiber is found in plant foods such as
fruits, vegetables, legumes, nuts, and whole grains. It can be found
in a variety of fruits and vegetables such as apples, oatmeal and oat
bran, rye flour, and dried beans. Both types are important to keep the
intestines clean.
Vitamins and minerals are the nutrients found in food that are also
essential for health. The most commonly known vitamins are A, B1, B2,
B3, B5, B6, B7, B9, B12, C, D, E, and K. The B and C vitamins are
water-soluble, excess amounts of which are excreted in the urine. The
A, D, E, and K vitamins are fat-soluble and will be stored in the body
fat.
Minerals are the building blocks that make up muscles, tissues, and
bones. They are also important components of many life-supporting
systems, such as hormones, oxygen transport, and enzyme systems.
