Nutrition is a term with many definitions. Most people understand it to mean a good diet, a healthy lifestyle, and supplementation with vitamins and minerals. It can also mean the science of how the body utilizes foods and nutrients, or the actual food itself. Healthy food in its natural state, plenty of fresh air and water, regular exercise to build muscle and fitness, and supplements if needed will keep or restore health.
To be healthy requires more than calories. This measurement of heat or energy produced by digestion dates from the 18th century, when the value of a calorie was established. 'Empty calories' are foods that can cause weight gain but offer no true nutritional value to the body. It is now known that we need vitamins, minerals, fiber, and other nutrients to thrive.
Whole foods contain dense nutrition in their natural, fresh form. When people lived mainly on food they produced themselves, this was not as much of a problem as it is today. Fresh vegetables from the garden, fruits from bushes and trees, and meat from the barnyard or from wildlife were staples for many generations.
When people moved to the cities and became dependent on store-bought food, this began to change. Foods were modified for commercial reasons, with either a disregard for health or an ignorance of what promotes it. Milk is one example. It was first pasteurized to kill tuberculosis germs and later homogenized, to make all milk look the same regardless of butterfat content. White bread became popular, even though much of the nutrition of wheat was lost when the bran was removed.
To extend shelf-life, essential fatty acids are removed, which has caused a general lack of these vital nutrients. Fiber is not popular with those who like soft or crisp baked goods, and vegetable oils used as common ingredients have been rendered unhealthy by processing. Sugar addiction is a problem for many and causes obesity, bone degeneration, and tooth decay, as well as vitamin and mineral deficiencies.
To maintain or to restore health, foods must be gotten as fresh as possible, cooked carefully to preserve their wholesomeness or eaten raw, and consumed in the whole state, rather than after processing. Artificial ingredients should be avoided by both adults and children. Essential fatty acids should be supplemented, unless good quality fish can be obtained, and chemical-free produce used whenever possible.
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.
