Healing Foods


In order to answer the question "What is a healthy diet?," it is important to first take a look at what our body is designed for. Is the human body designed to eat plant foods, animal foods, or both? Respectively, are we herbivores, carnivores, or omnivores?

Anatomy Specifications

While the human gastrointestinal tract is capable of digesting both plant and animal foods, there are indications that we evolved to digest primarily plant foods. Specifically, our teeth are composed of twenty molars, which are perfect for crushing and grinding plant foods, along with eight front incisors, which are well suited for biting into fruits and vegetables. Only our front four canine teeth are designed for meat eating, and our jaws swing both vertically to tear and laterally to crush, while carnivores' jaws swing only vertically. Additional evidence that supports the human body's preference for plant foods is the long length of the human intestinal tract. Carnivores typically have a short bowel, while herbivores have a bowel length proportionally comparable to humans.

Animal World Link

To answer the question of what humans should eat, many researchers look to other primates, such as chimpanzees, monkeys, and gorillas. These nonhuman wild primates are omnivores. They are also often described as herbivores and opportunistic carnivores in that although they cat mainly fruits and vegetables, they may also eat small animals, lizards, and eggs if given the opportunity. For example, the gorilla and the orangutan eat only 1 percent and 2 percent of animal foods as a percentage of total calories, respectively. The remainder of their diet is derived from plant foods. Since humans are between the weight of the gorilla and orangutan, it has been suggested that humans are designed to eat around 1.5 percent of their diet in the form of animal foods. However, most people derive well over 50 percent of their calories from animal foods.

Modern World Food Preferences

During the twenty century food consumption patterns changed dramatically. There were significant increases in the consumption of meat, fats and oils, and sug­ars and sweeteners in conjunction with a de­creased consumption of noncitrus fruits, vegetables, and whole-grain products. But the biggest change of human nutrition was the switch from a diet with a high level of complex carbohydrates, as found naturally occurring in grains and vegeta­bles, to a tremendous and dramatic increase in the number of calories consumed in the form of simple sugars. Currently, more than half of the carbohydrates being consumed are in the form of sugars such as sucrose (table sugar) and corn syrup, which are added to foods as sweetening agents. High consumption of refined sugars is linked to many chronic diseases, including obe­sity, diabetes, heart disease, and cancer.

Diet and Chronic Diseases

Weston A. Price, a dentist and author of Nutrition and Physical Degeneration, was observing the changes in teeth and palate (orthodontic) structure as vari­ous cultures discarded traditional dietary prac­tices in favor of a more civilized diet. Price was able to follow individuals as well as cultures over periods of twenty to forty years, and he carefully documented the onset of degenerative diseases as their diets changed.

Further research on the influence of diet preferences on human health was done by Denis Burkitt, M.D., and Hugh Trow­ell, M.D. Based on the extensive studies examining the rate of diseases in various populations (epi­demiological data), including the groundbreak­ing work of Dr. Price, and their own observations of primitive cultures, Burkitt and Trowell for­mulated the following sequence of events:

First stage: In cultures consuming a tradi­tional diet consisting of whole, unprocessed foods, the rate of chronic diseases, such as heart disease, diabetes, and cancer is quite low.

Second stage: Commencing with eating a more "Western" diet, there is a sharp rise in the number of individuals with obesity and dia­betes.

Third stage: As more and more people aban­don their traditional diet, conditions that were once quite rare become extremely common. Examples of these conditions include constipa­tion, hemorrhoids, varicose veins, and appen­dicitis.

Fourth stage: Finally, with full Westerniza­tion of the diet, other chronic degenerative or potentially lethal diseases, including heart dis­ease, cancer, osteoarthritis, rheumatoid arthri­tis, and gout, become extremely common.

It is obvious that there is a strong correlation between our diet and health condition and the choice is left for each of us to decide what to do with our own health.

Like any other therapies and treatments Dietary practices require that people take responsibility for their own health and healing. After all, a physician can prescribe a course of treatment, but no one can make us to take it!
