Vitamin A and D are fat-soluble vitamins that serve important functions. Vitamin A promotes good vision and skin health, and supports reproduction. Major food sources include animal products and carotenoids from plants. Vitamin D helps absorb calcium for bone health and is synthesized from sun exposure, with some foods like fatty fish and fortified milk providing it. Deficiencies can cause vision problems or rickets, while excesses pose health risks. Both vitamins are stable to cooking but may degrade during long storage.
Vitamins are substances that your body needs to grow and develop normally. There are 13 of these essential vitamins: A, C, D, E, K and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B-6, vitamin B-12 and folate).
You can usually get all your vitamins from the foods you eat. Your body can also make vitamins D and K. People who eat a vegetarian diet may need to take a vitamin B12 supplement to ensure that they are getting the vitamins usually found in meat.
Each vitamin has a specific job. If you have low levels of certain vitamins, you may develop a deficiency disease. Some vitamins may also help prevent medical problems. The best way to get enough vitamins is to eat a balanced diet with a variety of foods. In some cases, you may need to take a daily multivitamin for optimal health. However, high doses of some vitamins may make you sick.

Have you ever wondered how we stay healthy? The proper answer lies in
our balanced diet our balanced diet contains all the vital nutrients
including vitamins, proteins, carbohydrates.
The body needs vitamins to stay healthy and a varied diet usually gives you
all the vitamins you need. Vitamins do not provide energy (calories)
directly, but they do help regulate energy-producing processes. With the
exception of vitamin D and K, vitamins cannot be synthesized by the
human body and must be obtained from the diet. Vitamins have to come
from food because they are not manufactured or formed by the body. So
let’s find out the uses and the importance of vitamins in our daily life.
Hormones are compounds that are also known as signaling molecules. They
are produced by the glands in multi-cellular organisms. Hormones are
transported by the circulatory system to target distant organs in order to
regulate the physiology and behavior in living beings. A hormone is actually
a chemical messenger which is directly secreted into the blood stream. Blood
carries these hormones to various organs and tissues to exert their function.

and mostly this type of vitamins are absorbed in to body through fatty tissue
Vitamins are frequently classified as either fat-soluble or water-soluble organic substances.. minerals that dissolve in fat, such as vitamin A, vitamin D, vitamin E, and vitamin K, have a tendency to build up in the body. Water-soluble vitamins, such as vitamin C and the B-complex vitamins, such as vitamin B6, vitamin B12, and folate, must dissolve in water in order to be absorbed by the body. the body and cannot be stored. Any water-soluble minerals that the body does not use are mostly excreted in the urine. People require trace amounts of organic substances called vitamins. Every one plays a unique part in preserving health and body function. Some people may require supplements to improve their supply, depending on their lifestyle and overall health..

2. Vitamin
Any of a group of organic compounds which are essential for normal growth and nutrition and
are required in small quantities in the diet because they cannot be synthesized by the body.
There are two types of vitamins
Water soluble vitamin
Fat soluble vitamin
Fat soluble Vitamin
Fat soluble vitamins are those which soluble in fats and are supplied to the body through fat
containing foods.
Vitamin A
Vitamin D
Vitamin E
Vitamin K
The selected topic is Vitamin A & vitamin D
Vitamin “A”
It is also known as “RETINOL”
It is a pale yellow crystalline substance.
Retinol
3. Sources
Two different types of vitamin A are found in the diet. Preformed vitamin A is found in
animal products such as meat, fish, poultry and dairy foods. The other type, pro-vitamin A is
found in plant-based foods such as fruits and vegetables. The most common type of pro-vitamin
A is beta-carotene.
Vitamin A is also available in dietary supplements, usually in the form of retinyl acetate or
retinyl palmitate (preformed vitamin A), beta-carotene (pro-vitamin A) or a combination of
preformed and pro-vitamin A.
Beta-carotene
Functions
Vitamin A helps form and maintains healthy skin, teeth, skeletal and soft tissue, mucus
membranes, and skin. It is also known as retinol because it produces the pigments in the retina of
the eye.
Vitamin A promotes good vision, especially in low light. It may also be needed for reproduction
and breast-feeding.
Retinol is an active form of vitamin A. It is found in animal liver, whole milk, and some fortified
foods.
Carotenoids are dark-colored dyes (pigments) found in plant foods that can turn into a form of
vitamin A. There are more than 500 known carotenoids. One such carotenoid is beta-carotene.
Beta-carotene is an antioxidant. Antioxidants protect cells from damage caused by
substances called free radicals. Free radicals are believed to contribute to certain chronic
diseases and play a role in the aging processes.
Food sources of carotenoids such as beta-carotene may reduce the risk for cancer.
Beta-carotene supplements do not seem to reduce cancer risk.
4. Food Sources
Vitamin A comes from animal sources, such as eggs, meat, fortified milk, cheese,
cream, liver, kidney, cod, and halibut fish oil. However, all of these sources -- except for skim
milk that has been fortified with Vitamin A -- are high in saturated fat and cholesterol.
Sources of beta-carotene include:
Bright yellow and orange fruits such as cantaloupe, pink grapefruit, and apricots
Vegetables such as carrots, pumpkin, sweet potatoes, and winter squash
Other sources of beta-carotene include broccoli, spinach, and most dark green, leafy
vegetables.
Deficiency
If you don't get enough vitamin A, you are more likely to get infectious diseases and
vision problems.
The deficiency of Vitamin A can occur in persons with obstruction of the bile duct, since bile
salts are required for it absorption in the body
The deficiency of vitamin A in general, is associated with night blindness and skin kertinisation.
In child it deficiency causes retarded growth, however gorging in this vitamin in dosses of more
than 25,000 I.U. daily may lead to irregular thickening of some long bones, usually accompanied
by enlargement of liver, changes in skin, loss of hair, blurred vision and headache
Excess
If you get too much vitamin A, you can become sick. Large doses of vitamin A can
also cause birth defects.
The diseases of it is
Diarrhea
Vomiting
Nausea
Bone pain
Stability
Vitamin A and carotene are quite stable and are unaffected by normal cooking.
However, during frying and dehydration same of it may be lost oxidation of retinol during
storage will result in loss of this vitamin. This can, however, be minimized by the use of
antioxidants or by refrigeration.
5. VITAMIN “D”
It is also called “1-2-5-DIHYDROXY Vitamin D3”
It is also called “CALCITRYOL”
This active CALCITRYOL can be obtained from
Ergosterol
7-Dehydrocholestrol
Types of Vitamin D
Vitamin D2
Also called Ergocalciferol
Vitamin D3
Also called Cholecalciferol
Ergosterol converted Ergocalciferol in the present of Altera-violet radiation
Vitamin D2
Vitamin D3
6. Function
Vitamin D helps the body absorb calcium. Calcium and phosphate are two minerals
that are essential for normal bone formation.
Throughout childhood, your body uses these minerals to produce bones. If you do not get enough
calcium, or if your body does not absorb enough calcium from your diet, bone production and
bone tissues may suffer.
Vitamin D deficiency can lead to osteoporosis in adults or rickets in children.
Food Sources
The body makes vitamin D when the skin is directly exposed to the sun. That is why
it is often called the "sunshine" vitamin. Most people meet at least some of their vitamin D needs
this way.
Very few foods naturally contain vitamin D. As a result, many foods are fortified with vitamin
D. Fortified means that vitamins have been added to the food.
Fatty fish (such as tuna, salmon, and mackerel) are among the best sources of vitamin D.
Beef liver, cheese, and egg yolks provide small amounts.
Mushrooms provide some vitamin D. The vitamin D content is also being boosted by exposure to
some commercially available mushrooms to ultraviolent light.
Most milk in the United States is fortified with 400 IU vitamin D per quart. It should be noted
that foods made from milk, such as cheese and ice cream, are usually not fortified.
Vitamin D is added to many breakfast cereals and to some brands of soy beverages, orange
juice, yogurt, and margarine. Check the nutrition fact panel on the food label.
Supplements
It can be very hard to get enough vitamin D from food sources alone. As a result, some people
may need to take a vitamin D supplement. Vitamin D found in supplements and fortified foods
comes in two different forms:
D2 (ergocalciferol)
D3 (cholecalciferol)
7. Deficiency
Insufficient vitamin D have negative effect on insulin secretion
Remove the risk of high blood pressure
Excess
Too much vitamin D can make the intestines absorb too much calcium. This may cause
high levels of calcium in the blood. High blood calcium can lead to:
Calcium deposits in soft tissues such as the heart and lungs
Confusion and disorientation
Damage to the kidneys
Kidney stones
Nausea, vomiting, constipation, poor appetite, weakness, and weight loss
Stability
Vitamin D is quite stable to processing hence, cooking or other processing techniques do
not appreciably affect this vitamin in foods.
