Document Summary
Too little and too much food are both problematic from a global perspective: malnutrition= unbalanced diet (shortage of required nutrients or excess, undernourishment= too few calories on a chronic basis, over nourishment= too many calories on an ongoing basis. In canada, 48% of adults exceed their healthy weight and 14% are obese: calorie gap between rich and poor. Diseases of malnutrition: marasmus: sever deficit of energy, protein and carbohydrates, kwashiorkor: protein and micronutrient deficiency, diabetes, heart disease, obesity: excess fats, carbohydrates, calories. Often have electricity and no safe drinking water. Health, education and sanitation services are poor. Many have no land of their own and work seasonally: urban poor. No means to produce food; have few resources to buy it: victims of catastrophes. Floods, droughts, earthquakes, etc force people to abandon land. Why can"t we feed everyone: farmers today produce more than enough calories to feed everyone.
