Document Summary
Nutrition is a science that studies all the interactions that occur between living organisms and food. Food provides nutrients and energy, which are needed to keep us alive and healthy, to support growth, and to allow reproduction. Sometimes, however, fast-paced lifestyles and food choices made available through modern technology contribute to a diet that contains too much or too little of some of the nutrients we need. Over the past century the major nutrition concerns in the united states have shifted from providing enough nutrients to meet people"s needs to limiting overconsumption and the chronic diseases related to excess of energy and certain nutrients. Although the modern american lifestyle tempts us with convenience, we need to consider the costs to our wallets and our waistlines. Recommendations suggest a diet based on whole grains, vegetables, and fruits, with smaller amounts of low-fat dairy products and lean meats with limited amounts of sweets and certain types of fats.
