Virtually every country in the world has the
potential of growing sufficient food on a
sustainable basis. The Food and Agriculture
Organization of the United Nations has set
the minimum requirement for caloric intake
per person per day at 2,350. Worldwide,
there are 2,805 calories available per
person per day. Fifty-four countries fall
below that requirement; they do not
produce enough food to feed their
populations, nor can they afford to import
the necessary commodities to make up the
gap. Most of these countries are in subSaharan Africa.

The Importance of Food
• Food provides materials and nutrients for cell growth. It
provides us with the energy we need for growth, physical
activity and the basic body functions (breathing, thinking,
temperature control, blood circulation, digestion and helps
resistance to disease).
• Food gives the body energy – Kilojoules (KJ) or Calories
(Note: if all of the Calories that we eat are not burned up for
energy use the body stores these calories as Fat).
– An average person needs about 2200 kcal per day.
– A Canadian gets on average 2900 KJ per day.
Food: Nutrients
• The types of nutrients in food are carbohydrates, proteins,
fats, vitamins, minerals and water. All foods contain one or
more of these nutrients in varying amounts. Each type of
nutrient serves particular functions. This is why diversity in
our diets is important for good health.
• Although one may eat enough kilo-calories of food, one
can still suffer from malnutrition, if there is a lack of
essential nutrients.
• This can result in a variety of diseases.
