Nearly one-half of all children below age 5 or 6 are

Millions of children and women suffer from one or
more forms of malnutrition
One generation to the next as malnourished
mothers give birth to infants who struggle to

5. DefinitionDefinition
Nutrition is the science of how the body
uses food., that studies the interactions
between living organisms and food.
Nutrition is defined as the food, we eat,
air we breathe, water we drink,
supplements we ingest, and all that we do
that literally “feeds” or nourishes the
body for its own health benefit.
6. NutrientsNutrients
An important aspect of nutrition is the daily
intake of nutrients.
Nutrients consist of various chemical
substances in the food that makes up each
person’s diet.
Many nutrients are essential for life, and an
adequate amount of nutrients in the diet is
necessary for providing energy, building and
maintaining body organs, and for various
metabolic processes.
7. Essential NutrientsEssential Nutrients
Nutrients are essential to the human diet if
they meet two characteristics.
First, omitting the nutrient from the diet leads
to a nutritional deficiency and a decline in
some aspect of health.
Second, if the omitted nutrient is put back into
the diet, the symptoms of nutritional deficiency
will decline and the individual will return to
normal, barring any permanent damage caused
by its absence.
8. Nutrient ClassificationNutrient Classification
There are six major classes of nutrients found in
food:
carbohydrates,
proteins,
lipids (fats and oils),
vitamins (both fat-soluble and water-soluble),
minerals, and
Water.

10. Nutrient ClassificationNutrient Classification
Nutrients are grouped into :
Macronutrients are those which the body requires in
large amounts e.g. proteins, fats, carbohydrates, water .
These requirements are measured in grams.
Micronutrients are those which the body requires in
small amounts .These requirements are measured in
milligrams. (1/1000gm) and micrograms (1/10,00,000
gms) e.g. vitamins, minerals and antioxidants
11. Functional Classification of NutrientsFunctional Classification of Nutrients
Energy yielding Foods : foods rich in Carbohydrates
and fats such as cereals, sugar, and roots
Body building foods: Foods rich in protein such as
meat, liver, fish, milk and pulses
Protective foods: These are foods rich in proteins,
vitamins and minerals.They are fruits, green leafy
vegetables, liver, eggs, milk and fish
35. Exercise: Food Ratio
Hello Friends:
When someone asks me
what exercises they
should do for weight loss,
I instead immediately
ask, “How is your diet?”
Nutrition and diet is by far
the #1 cause for weight
gain and loss. Once
proper diet and nutrition
is in place, THEN add
exercise and activity into
your routine.

Editor's Notes
This lecture will cover the basics about nutrition.
7. Communities Should Restrict Availability of Less Healthy Foods and Beverages in Public Service Venues
Less healthy foods and beverages include foods and beverages with a high calorie, fat, sugar, and sodium content, and a low nutrient content.
Public venues can restrict the availability of less healthy foods by setting standards for the types of foods sold, restricting access to vending machines, banning snack foods and food as rewards in classrooms, prohibiting food sales at certain times of the school day, or changing the locations where unhealthy competitive foods are sold.
Other public service venues that could also restrict the availability of less healthy foods include after-school programs, regulated child care centers, community recreational facilities (e.g., parks, recreation centers, playgrounds, and swimming pools), city and county buildings, and prisons and juvenile detention centers.
9. Communities Should Limit Advertisements of Less Healthy Foods and Beverages
Research has demonstrated that more than half of television advertisements viewed by children and adolescents are food-related; the majority of them promote fast foods, snack foods, sweets, sugar-sweetened beverage products, and other less healthy foods that are easily purchased by youths (11).
In 2006, major food and beverage marketers spent $1.6 billion to promote food and beverage products among children and adolescents in the United States (64). Television advertising has been determined to influence children to prefer and request high-calorie and low-nutrient foods and beverages and influences short-term consumption among children aged 2--11 years (65).
Therefore, limiting advertisements of less healthy foods might decrease the purchase and consumption of such products. Legislation to limit advertising of less healthy foods and beverages usually is introduced at the federal or state level. However, local governing bodies, such as district level school boards, might have the authority to limit advertisements of less healthy foods and beverages in areas within their jurisdiction (9).
