Is FOOD healthy ?

the food is an amazing thing :) but did you know that :

In developing countries, lack of food and poor usage of the available food can result in protein–energy malnutrition ; 50 million pre school African children have PEM. In developed countries, excess food is available and the most common nutritional problem is obesity. Diet and disease are interrelated in many ways. Excess energy intake, particularly when high in animal (saturated) fat content, is thought to contribute to a number of diseases, including ischaemic heart disease and diabetes. A relationship between food intake and cancer has been found in many epidemiological studies; an excess of energy-rich foods (i.e.fat and sugar containing), often with physical inactivity, plays
a role in the development of certain cancers, while diets high in vegetables and fruits reduce the risk of most epithelial cancers. Numerous carcinogens, either intentionally added to food (e.g. nitrates for preserving foods) or accidental contaminants, may also be involved in the development of cancer.The proportion of processed foods eaten may affect the development of disease. A number of processed convenience foods have a high sugar and fat content and therefore may predispose to dental caries and obesity, respectively. They also have a low fire content, and dietary fire is possibly necessary in the prevention of a number of diseases Some epidemiological data suggest that there are long-term effects of undernutrition, low growth rates inutero being associated with high death rates from cardiovascular disease in adult life.
