Nutrition is the science that interprets the interaction of nutrients and other substances in food (e.g. phytonutrients, anthocyanins, tannins, etc.) in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion. A poor diet may have an injurious impact on health, causing deficiency diseases such as blindness, anemia, scurvy, preterm birth, stillbirth and cretinism; health-threatening conditions like obesity and metabolic syndrome; and such common chronic systemic diseases as cardiovascular disease, diabetes and osteoporosis.
Some 795 million people in the world do not have enough food to lead a healthy active life. That's about one in nine people on earth.One out of six children -- roughly 100 million -- in developing countries is underweight. Reduce food waste by improving product development, storage, shopping/ordering, marketing, labeling, and cooking methods. Recover food waste by connecting potential food donors to hunger relief organizations like food banks and pantries.
