Nutrients.

6. Nutrients

7. There are different types of Nutrients present in our
food. These are also called components of food.
Six types of components:
Carbohydrates
Proteins
Fats
Vitamins and Mineral
Water
Roughage

8. Carbohydrates are one of the main types of nutrients.
They are the most important source of energy for your
body. Your digestive system changes carbohydrates into
glucose (blood sugar).
Your body uses this sugar for energy for your cells, tissues
and organs. It stores any extra sugar in your liver and
muscles for when it is needed.

10. CARBOHYDRATES
Mainly provide energy to our body
Carbohydrates – manly they provide instant energy to
our body .Glucose is present in the form of starch and
sugar.

body. There are called Body building food.

16. Protein is an important component of every cell in the body. Hair
and nails are mostly made of protein. Your body uses protein to
build and repair tissues.
You also use protein to make enzymes, hormones, and other body
chemicals. Protein is an important building block of bones, muscles,
cartilage, skin, and blood.
PROTEINS

18. Milk: Milk is very nutritious and is a rich source of
protein. It also contains calcium for healthy bones.
Egg: Chicken eggs are a rich source of protein and
vitamins.

19. Meat: Meat of animals such as goat, chicken, fish and prawns are
eaten.
Pulses: Pulses are part of a healthy, balanced diet and have been
shown to have an important role in preventing illnesses such as
cancer, diabetes and heart disease. Pulses are a low fat source of
protein.
MEAT & PULSES

20. • Paneer : paneer is called as cottage cheese.

21. •The foods we eat contain nutrients that provide energy and other
substances the body needs. Most of the nutrients in food fall into
three major groups: proteins, fats, and carbohydrates.
•The body uses fat as a fuel source, and fat is the
major storage form of energy in the body.

22. Food Items Rich In Fats

23. •Obesity is generally caused by eating too much and moving too
little. If you consume high amounts of energy, particularly fat and
sugars, but do not burn off the energy through exercise and
physical activity, much of the surplus energy will be stored by the
body as fat.

24. VITAMINS
• Vitamins help in protecting our body against diseases.
• They also keep our eyes, bones teeth and gums healthy.
• Some of vitamins are soluble in water whereas others are
• soluble only in fats or oils, so, on the basis of their solubility, all the
vitamins can be divided into two classes or two groups; water soluble
vitamins and fat soluble vitamins.

25. Water soluble vitamins and fat soluble vitamins.
1. Water soluble vitamins are;- vitamin B-complex and Vitamins C
2. Fat soluble vitamins are;- Vitamin-A, Vitamin-D, Vitamin-K
Vitamin-E Called pernicious anemia. The various source of this
vitamin are : meat, liver milk & eggs etc.

26. Vitamin A is a fat-soluble vitamin that is good for healthy vision,
skin, bones and other tissues in the body. Vitamin A often works as
an antioxidant, fighting cell damage, but it also has many
other uses.

27. B vitamins play a vital role in maintaining good health and well-
being. As the building blocks of a healthy body, B vitamins have a
direct impact on your energy levels, brain function, and cell
metabolism. Vitamin B complex helps prevent infections and helps
support or promote: cell health.

28. The body uses vitamin C in many different ways. Vitamin C is
needed by the body to form collagen. According to the NIH, the
body also uses vitamin C to make skin, tendons, ligaments and
blood vessels. It also uses this vitamin to repair and maintain
cartilage, bones and teeth, to heal wounds and to form scar tissue.

29. Vitamin D is a group of fat-soluble secosteroids responsible for
increasing intestinal absorption of calcium, magnesium, and
phosphate, and multiple other biological effects.

30. Vitamin E oil is an ingredient in many skincare products; especially
those that claim to have anti-aging benefits. Vitamin
E supplements may prevent coronary heart disease , support
immune function, prevent inflammation , promote eye health, and
lower the risk of cancer.

31. Vitamin K is a group of structurally similar, fat-soluble vitamins
that the human body requires for complete synthesis of certain
proteins that are prerequisites for blood coagulation and which
the body also needs for controlling binding of calcium in bones and
other tissues.

32. MINERALS
• Minerals are required in small amounts in our body.
• They are essential for proper growth of body and for
maintaining good health.

35. Half of our weight is water.
Enables you to swallow and digest foods.
 Absorb other nutrients, and eliminate wastes.
 The typical suggestion is we must drink 6-8 glass of water every

36. Roughage does not provide any nutrients to our body but it is an
essential ingredient of our food as it helps our body to get rid of un
digested food.
So we need to have a little of all kinds of food every day to get all
the Nutrients and roughage etc. This type of diet is called A
balanced diet .A balanced diet should contains 50%
carbohydrate,35%fats,12%protiens. 3% vitamins & minerals and
sufficient amount of water.
