Nutrition, nourishment, or aliment, is the supply of materials - food - required by organisms and cells to stay alive. In science and human medicine, nutrition is the science or practice of consuming and utilizing foods. A nutrient is a chemical that an organism needs to live and grow or a substance used in an organism's metabolism which must be taken in from its environment.[ What is Nutrition?

Nutrition is:
* utilization of food to grow, repair and maintain our bodies; * getting the right amount of nutrients from healthy foods in the right combinations; * making smart choices about the foods you eat;

* proper nutrition helps you develop and maintain good health; * a choice — choose good nutrition and a healthy lifestyle! Sign up for the newsletter and get free weekly Healthy Lifestyle recipes and tips.

The essential nutrients for life include carbohydrates, proteins, and lipids (fats), as well as fiber, vitamins, minerals, and water—the solvent for all soluble ingredients in the blood and cells. The absorption of nutrients starts the moment we begin to digest our foods, as they are transported to assist all the metabolic processes in the human body. Good nutrition means getting the right amount of nutrients from healthy foods in the right combinations. Having nutrition knowledge and making smart choices about the foods you eat can and will help you achieve optimum health over your lifetime, and be a key to avoiding obesity, illness, and many of today’s most prevalent chronic diseases. Nutrition is just one key to developing and maintaining good health. Good health is defined as a state of complete physical, mental and social well-being — a healthy mind, body, and spirit. Nutrition is at work during our entire life-cycle — from infancy to adolescence, adulthood and in our senior years — and can be the antidote for many of today’s common problems, such as stress, pollution, sexual vitality, and disease prevention. For me personally, nutrition translates into health, and health is freedom. Being healthy not only makes us feel great, it enables us to enjoy life to our fullest potential, and to follow our dreams. Conversely, a poor diet can have a serious impact on health, and rob you of your freedom. Food therapy is emerging as the latest prevention against multiple lifestyle diseases. Experts now believe it’s better to pop an apple, rather than popping a pill.  Negative influences such as stress, shock, injury, emotional upsets and worries can have a direct impact on life-long health. The good news is that the body can heal itself, if given what it needs to do its job. The nutrition in certain foods can naturally increase your body’s oxygen levels, eliminate many sources of toxins, improve your digestion, and prevent, heal, or reduce the severity of various diseases. Nutrition is about choices. Healthy eating is the best recipe for an abundant life. Make every bite count.
