Food We Eat
Food is essential for our body to develop, replace and
repair itself. Food provides us energy to work and play. It protects us from
diseases and help to recover fast from illness. We eat different food item and
each food item contains different substances. These substances that provide
nourishment essential for the maintenance of life and for growth are called
nutrients are carbohydrates, proteins, vitamins, fats, minerals. No single food
contains all the nutrients in the desired quantities so; we need to eat balance
diet for proper functioning of body.
Carbohydrates provide energy for the body. We need
energy for all activities we do. Carbohydrates include sugars found naturally
in foods such as fruits (apples, banana and grapes), vegetables (potato and
pumpkin), milk, milk products, whole grain breads and cereals (wheat, maize and
rice), starchy vegetables, legumes and refined sugar.
Fats also provide energy for the body. They act as
reserve of energy when carbohydrates are not available. It
helps to keep body warm. Food rich in fats include oil, butter, nuts, coconut,
ghee, cheese, cream etc.
It is important for the maintenance and repair of the
body. Children require more protein for their growth. Protein rich foods
include meat, fish, cheese, beans, lentils, yogurt, nuts, and seeds.
Vitamin helps to form and maintain healthy teeth, bones
and skin. It helps to fight against infection and diseases. Food rich in
vitamins are broccoli, papaya, almonds, sunflower oil, spinach, carrot,
pumpkin, orange, beans etc. All citrus fruits contain a lot of vitamin ‘c’ that
help to fight against infections.
The body needs many minerals such as calcium, iron,
sodium, potassium and many others. We need all minerals in to stay healthy in
desired quantity. Our body needs calcium to maintain healthy bones and teeth.
Calcium we get from milk, milk products etc. Iron is also a mineral which helps
in the formation of blood. Iron rich food includes red meats, dried fruits,
green leafy vegetables.
Water helps to regulate the body temperature. It is an
important constituent of blood, skin, digestive juices etc.in our body.
Roughage is the indigestible portion of food derived
from plants. It clears our stomach. It is obtained from fruits, vegetables and
the outer covering of cereals and pulses.
a diet that has proper proportions of carbohydrates, fats, proteins, vitamins,
minerals, and water necessary to keep good health is called balanced diet.
cook food to improve its taste and to make it soft. It also kills germs present
in raw food. Cooked foods are soft, so it is easily digested by the body.

or cook vegetable in enough water. If vegetables are cooked in excess water,
its water soluble nutrients get dissolved in water and in case we drain out
that excess water, nutrients also goes away with water. So, better idea to use
excess water to make curry or some soup.
generally eat fruit raw. There are some that we eat raw such as carrot, radish,
cucumber, tomato etc. If we cook them, their nutrition value may be lost. But
we should wash them thoroughly before eating them raw.
Sprouting and Fermentation
and Fermentation are process of preparing food that enhances its nutrition
value. Sprouted moong and gram are rich
in vitamins and proteins. Mixture used for idli is fermented overnight and then
cooked in steam. Food cooked in steam does not lose its nutrition value.
Fermented food is easy to digest.
can make sprouts easily at home. Soak some grams in water overnight and then
keep the grams in wet cloth for few hours. Sprouts will appear. We can make
sprouts healthy snacks by adding chopped onion, tomato, green chilli, coriander
item kept uncovered are exposed to dust and flies. Flies carry germs on their
body and cause diseases like diarrhea, typhoid etc. when food are exposed. We
should avoid eating uncovered and cut food sold in streets. Foods also get
spoiled when they are left for long time as germs grow quickly when there is
moisture (water) and warmth. We can see black, green or grey patches on chapatti
or bread kept outside the fridge for many days. These patches are germs.
We can preserve food for long time by using
- Salting:It is one of the oldest
methods of preserving food. Fish and pickles preserved in this manner. Salting
preserves food by drawing water out of the food, preventing bacteria growing
and spoiling the food.
- Boiling:Boiling controls the growth of germs in
food. That is why we boil milk to
prevent it from getting spoilt. Boiling prevent the food from spoilage
for short period of time.
is an easy method of preserving food for few days. It preserves taste, texture,
and the nutritional value of foods. We can keep fruit, vegetables and cooked
food in a refrigerator.
- Dehydration:Drying food items under sun draws away
water and prevents germs growth. We can use this method to preserve food items
such as raw mango, cauliflower, fish, and potato chips.
- Sweetening:Adding excess sugar to food items also
stop germs growth. We prepare jams, jellies, murabbas by adding sugar and can
preserve them for long time.

- Always wash hands before

- Always wash fruit and
vegetables before using them.
- Always eat fresh cut fruit
