Nutrition is variously described as a bodily process of utilizing food, as the actual supply of nutrients from foods eaten, and as the science of metabolism as it pertains to nutrients taken in, digested, and delivered for use by the body. For those of us who are not scientists, it means healthy food, supplements, and other necessary things that build health and improve the quality of life.
Most of us know that there are high and low calorie foods. Calories are used to measure how much heat is produced in metabolism. Calories are not all bad; the ones that are combined with valuable nutrients provide energy. However, 'empty calories' in foods devoid of nutrients are detrimental to health. They can even be negatives, if their digestion drains stored vitamins and minerals from the body.
Whole, fresh foods hold out the best hope of a diet sufficient in vitamins, minerals, and other beneficial substances. For many generations, people lived on food that they produced or gathered themselves, and this food provided what they needed to maintain health and stave off illness. Vegetables from the garden, fruit off the trees, grain from the fields, and meat from the barnyard were staples of everyday diets.
Foods are modified for commercial reasons. Fresh fruits are both expensive and perishable. It's easier to stock up on canned fruits and vegetables, frozen fruit juices, or frozen vegetables. Milk, once drunk raw (unpasteurized) and fresh from the cow or goat, is now pasteurized and homogenized. Unfortunately, much of the goodness of the natural food was lost along the way.
Today essential fatty acids are removed to prolong shelf life, fiber is lost when baked goods are valued for their soft texture, and sugar addiction cause people to seek satisfaction in empty calorie foods. Vegetables and fruits may be sold as fresh but transported from far away. Vitamins are fragile things, and their presence begins to decline as soon as the food is harvested.
An effort must be made to obtain foods in a natural state, as fresh as possible, and in quantity suited to daily activity. Food allergies or sensitivities should be taken into account. Sugary foods, refined foods, and packaged foods full of artificial colors, flavors, and preservatives should be eliminated altogether or strictly limited. Children should be taught early on the value of a diet rich in good fats, plentiful fiber, adequate protein, and fruits and vegetables for vitamins and minerals.
Not all of a nutritional program concerns food. Exercise to tone muscle and promote fitness is very important. Walking, weight training, and body building tone muscles and strengthens the digestive tract and other internal organs. An adequate supply of pure water every day is vital. Deep sleep, which escapes many, is also necessary. Breathing from the diaphragm, as happens during exercise, is another health booster.
Nutrition should be the basis of everyone's lifestyle. This would result in a tremendous reduction of pain, illness, expense, and loss of productivity. Feeling good, building muscle and fitness, and enjoying life are within reach of us all, if we are wise enough to implement them.
