2015968864Number one nutrition problem in North America...Poor diet, excessive food intake, and too little physical activity.0
2015968865NutritionThe science that links food to health and disease. It includes the processes by which the human organism ingests, digests, absorbs, transports, and excretes food.1
2015968866NutrientsChemical substances in food that contribute to health, many of which are essential parts of a diet. Nutrients nourish us by providing calories to fulfill our bodies energy needs, nutrients for building body parts, and factors to regulate necessary chemical processes in the body.2
2015968867Essential NutrientA substance that, when left out of the diet, leads to signs of poor health. The body either can't produce this nutrient or simply can't produce enough to meet the body's requirements. Then, if added back to the diet before permanent damage occurs, the affected aspects of health are restored. Essential Nutrient.3
2015968868GlucoseA six-carbon sugar that exists in a ring form; found as such in blood, and in table sugar bound to fructose. Also known as dextrose, it is one of the simple sugars.4

2015968871CancerA condition characterized by uncontrollable growth of abnormal cells.7
2015968872Cardiovascular DiseaseA general term that refers to any disease of the heart and circulatory system. This disease is generally characterized by the deposition of fatty material in the blood vessels. This leads to the hardening of the arteries, which can lead to organ damage and death. Also called CHD, or Coronary Heart Disease, since the vessels of the heart are the primary sites of disease.8
