Right to “Adequate food”: Quantity and Quality - macronutrient quantity and quality AND - micronutrient density per unit energy consumed Nutrient poor high energy foods displace nutrient rich foods Effect most marked at low levels of physical activity Leading to: - poor/abnormal fetal growth - low birth weight - stunting -increased risk of obesity

Editor's Notes
Non communicable diseases include premature heart disease, stroke, diabetes, and cancers. Overweight and Obesity are serious underlying problems that increase risk of NCDs. If one looks ate the mortality from diseases it is already evident in the year 2000 that NCDs have overtaken infectious diseases in most regions of the world apart from Africa. High cholesterol accounts for 4 million premature deaths while high blood pressure is responsible for 7 million premature deaths. It has been projected that in 2020: 71% of deaths due to heart disease, 75% due to stroke and 70% due to diabetes, will be in developing countries. Premature death and disability from NCDs are the result of unhealthy diets and lack of physical activity. They are largely preventable by healthy diets and lifestyles.
