Our body: The human body is just like a machine. Like an engine burning up fuel, in order to generate the required energy, the human body uses the consumed food in order to generate the driving forces to keep the heart beating, the lungs breathing and the limbs functioning.

Hunger: Hunger is a state during which the human body lacks the basic food intake to produce the necessary energy and nutrition to be fully active. Hunger is of two types:

  • Acute Hunger
  • Chronic Hunger

Acute hunger is sudden and life threatening. It needs immediate and intense treatment. The cause can vary, depending on the situations such as conflict or natural disaster. Acute hunger accounts 8% of the world’s hunger.

Chronic hunger is gradual and occurs seasonally. When occurred, it can last for generations. It is less visible but affects many people.

Both Acute hunger as well as chronic hunger can lead to malnutrition.

Nutrition: The terms ‘food’ and ‘nutrition’ are sometimes used synonymously. Literally, it is not right. Food is a composite mixture of various ingredients that is consumed for nutrition.

Myth 2: Natural disasters and famines which cannot be controlled by people causes hunger.
Reality: This is a generalized term. Approximately 8% of the hunger problem in the world is caused by natural disasters and famine.

Myth 3: Population explosion causes hunger
Reality: Contrary to the myth believed by people, overpopulation is never the root cause of hunger. But it can be the other way around – hunger can be a primary cause of population explosion.

Food is essential

Food is essential to drive away hunger and malnutrition. Our body needs sufficient food to survive through. It gives us the required energy and sufficient nutrients to grow and develop to be healthy and energetic, to move around, work, exercise, play, think and learn. Our body needs a variety of the following 5 nutrients

  • Protein
  • Carbohydrate
  • Fat
  • Vitamins
  • Minerals

These nutrients are usually got from the food we eat every day to stay healthy, active and productive.

Protein – builds, maintains and repairs the body’s muscle, blood, skin, bones and other tissues and organs in the body. Meat, eggs, dairy and fish are the common foods that are rich in protein.

Carbohydrate – is main source of energy that is being provided to the body. Carbohydrates can be classified into two kinds; starches and sugars. The common starch rich food include rice, maize, wheat and potatoes while food rich in sugars include fruit, honey, sweets and chocolate bars.

Fat – This is also known as the body’s secondary source of energy. Fat helps people survive through during cold weather and actually is responsible for more energy or calories per gram than any other nutrient. Compared to the other nutrient, fat is more difficult to burn. Food rich in fats are oils, butter, lard, milk, cheese and some meat.

Vitamins and Minerals – Vitamins and minerals are needed in very small amounts by the human body and are sometimes called micronutrients, but are essential for good health, especially for the organs in the body. They basically control many functions and processes in the body, and in the case of minerals also help build body tissue such as bones (calcium) and blood (iron). Ever since the discovery of vitamins, the world has redefined the science of nutrition.

Thus, food is a very basic necessity for every human body to survive and to be healthy.
