Document Summary
Food analysis = development, application and study of analytical methods for characterizing foods and their constituents. Government regulations eliminate economic fraud and maintain fair competition. Quality control monitor and maintain quality of food supply. Inform consumers, can make educated choices about the food they consume. **any naturally grown, non-processed food does not need a nutritional guide, unless it is gmo. *more interested in the gram amounts than the daily% *top of label is must, bottom half is optional. Nutrient-dense foods (broccoli = high in vit c & vit k) *nutrient dense does not always mean calorie dense. *calorie dense does not always mean nutrient dense. Sufficient for animal diets, but starting point for human consumption: moisture = water. Animal feeds are highly variable in moisture content. Storage conditions high moisture = shorter shelf life, microbes thrive. Price contributes to the weight but is empty calories, transport. ** feed often done on dry matter basis for these reasons.
