Introduction: Nutrition can be defined as the supply of nutrients to our bodies through eating
food. Every living organism including plants in this world requires nutrition. Lack of nutrients in
diet can result in many diseases including various deficiency diseases. A nutritious diet contains
all the macro and micro nutrients in proper proportion which is required for growth and
developments. Macronutrients are proteins, fats and carbohydrate. Micronutrients such as
vitamins and minerals are also equally important for healthy body. Macronutrients provide
energy and strength to our body whereas micronutrients help to maintain normal cellular
functions.
Nutrition in American society: American view food as a royal road to health, sanity and
longevity. According to Charles Tart, “Americans have the delusion that we can eat our way to
enlighten. America has a variegated history of nutritional theories, diet, food and nutritional
disorders. Although, Americans are gradually becoming inclined to the eating healthy diets, still
obesity and malnutrition are increasing the risk of health problems related to diet in America.
The emergence of obesity in America epidemic can be seen in 1970 and after that it continued to
increase its rate. (Department of Health and Human Services, 2001; Flegal et al., 2002, p. 1723–
1728; Ogden, 2000, p. 1728-1732). The main contributor to the increasing rate of obesity in
America is the positive energy balance. There is a gradual increasing trend of eating away from
home in Americans which results in creased energy intake ultimately resulting in the increased
adiposity. Nowadays, the main focus of childhood nutrition is not restricted to prevention of
nutrition deficiency diseases but also to reduce over consumption of nutrients to reduce the risk
of obesity related health problems. Today, the number of overweight American children is
increasing at an alarming rate and this can be attributed to the changing life style and decreased
physical activity. In last decade the number of overweight children in America has doubled
increasing the risk of future health problems. In addition low intake of calcium in children is also
a new area of concern (Kleinman, 1998). Inadequate calcium supply affects skeletal development
and bone mineralization increasing risk of osteoporosis. Following are few nutrition statistics in
past few years:
1. In the year 1999, a survey of rural and urban children in North Carolina revealed that...
