The ABCD’s of Vitamins

The ABCD’s of Vitamins


In this presentation we will explain
what vitamins are and their functions in the body. We will be taking a closer look
at four of these vitamins, their function, and the consequences when we’re
deficient in any of them. We all remember taking vitamins as kids but what exactly
are these vitamins and what do they do? Vitamins are essential nutrients needed
by the body in small amounts to allow it to grow, develop, and function normally. In
total, there are thirteen vitamins needed by the body. Vitamins come in two types
that are transported and stored differently in the body. These are:
water-soluble and lipid soluble vitamins. Water soluble vitamins dissolve in water
and are able to move around freely in the body through the blood. These
vitamins are found in the watery portions of fruits, vegetables, and grains.
Water soluble vitamins are not stored in the body. The body takes the vitamins
needed from our food and the remainder is disposed of through the kidneys. This
means that water soluble vitamins need to be regularly replenished as part of
our daily diet. Fat soluble vitamins, on the other hand, need fat in order to
dissolve. These vitamins require special carrier proteins to be transported in
the blood. Unlike water soluble vitamins, fat soluble vitamins are stored in fat
cells when excess vitamin is present in the diet,
to be used at a later time. Now let’s take a look at two water soluble
vitamins: vitamins B and C. We’ll now be talking about one common water soluble
vitamin, vitamin B. There are 8 types of vitamin B and most of them come from
our diet. Due to the various types of vitamin B, they can be found in a variety
of sources. In terms of the roles vitamin B perform two main functions in the
human body: one to make energy from the ingested food and two to make red blood
cells. It’s important to note that some vitamin B types only perform one of
these functions but there are also other types that are involved in both
functions. Deficiency in vitamin B can lead to one or more diseases depending
on the number of types of vitamin B deficiency.
For example, deficiency in vitamin B12 and vitamin B6 can cause anemia, which is
insufficient red blood cells. On the other hand deficiency in vitamin B1 and
B3 can lead to mental confusion. Now we will take a look at another
water-soluble vitamin, vitamin C. Vitamin C has various functions in the body one
of its most important functions is to protect the body from infections. It also
contributes to the growth and repair of tissues. Umm, not those kind of tissues. The tissues in your body like your bones your teeth and your skin!
Now, you may be wondering where you can find vitamin C. Well the best sources of
vitamin C are fruits and vegetables. Peppers and broccoli have the highest
vitamin C content among the many kinds of vegetables. Now, it’s commonly believed
the oranges are the best source of vitamin C among fruits, however, this is
not actually the case. The fruit that is the best source of vitamin C is actually
guava, in second place it’s papaya, and kiwis are the third best source of
vitamin C among fruits. Oranges are actually the fourth highest. So what
happens when you don’t consume enough vitamin C? Well vitamin C deficiency can
lead to a disease called scurvy. Scurvy was a disease that many pirates and
sailors used to have when they were out at sea for long periods of time without
access to fresh fruits and vegetables. You see, vitamin C is necessary to
produce collagen. Collagen is the main protein component of the tissues in your
body and collagen alone makes up 35% of the whole body’s protein content. Scurvy
has many symptoms such as brown spots in the skin, bleeding from different mucous
membranes, spongy gums, loss of teeth, and even death. Now look at two fat soluble
vitamins: vitamins A and D. We will first take a look at vitamin A. Vitamin A’s
main role in the body is maintaining and protecting vision. Vitamin A is critical
for vision because it’s a component of rhodopsin—a protein that detects and
absorbs light in the eyes. There are two main sources of vitamin A. The first, is
in foods from animal sources, which includes fish, meat, liver, and eggs. The
second, is in leafy green vegetables, orange and yellow vegetables, and fruit.
The top three choices are squash, carrot, and spinach. A deficiency in vitamin A is
usually rare since most foods contain at least a small amount of it. Vitamin A
deficiency is usually much more prevalent in developing countries like
Nigeria and India where access to food is much more restricted. Deficiency is
more common during periods of high nutritional demand such as during
infancy and childhood. One of the most common symptoms of vitamin A deficiency
is xerophthalmia, or the inability to see in low light or in darkness. The second
fat soluble vitamin we will be talking about is vitamin D. Vitamin D is also
known as the sunshine vitamin because it’s produced in your skin in response
to sunlight. You can also get vitamin D from supplements and a very small amount
comes from some foods like salmon. Vitamin D works to promote bone growth
and bone strength. This is important since vitamin D regulates the absorption
of calcium and phosphorus, which are two essential components for developing the
structure and strength of your bones. So, even if you eat lots of foods that
contain calcium and phosphorus, without enough vitamin D you can’t absorb them
into your body. Vitamin D is also an important factor in making sure your
muscles, heart, lungs, and brain work well and that your body is able to fight
infection. Too little vitamin D results in the softening of the bone
this disease is known as rickets in children and osteomalacia in adults.
Vitamins are essential nutrients needed by the body to grow, develop, and function
normally. The two types of vitamins are fat soluble and water soluble vitamins.
We discussed two water soluble vitamins vitamin B involved in the production of
energy and red blood cells and vitamin C which is associated with tissue growth
and repair. We also discussed two fat soluble vitamins: vitamin A which plays a
role in vision and vitamin D which is involved in bone growth and strength.

  1. Dont know about nigeria but who told u that Access to food in India is restricted!!!Get proper knowledge before giving opinion..

  2. The word "Fruit" is already plural. Please, stop saying Fruits.
    There is no such word in the American diction, and this word "Fruits" exists in foreign countries not here!

  3. Don't waste your time. I spent 8/9 months on vitamins. What a waste of time and money. They are made by the pharmaceutical companies. They don't work. Get your vitamins in your food.
