Sunlight – a vital nutritive factor in life

“Sunlight is vitally important in the nutritive processes of both plant and animal life. Perhaps we cannot call it a food, but we can, at least, call it an accessory nutritive factor. Its office would seem to be somewhat like, if not identical with that of the vitamins. Take away sunlight and all life upon earth would perish. In the tropics, where the sunlight is most abundant, life exists in greatest profusion. In those portions of the earth where nights are longest and days are shortest, and where long winters prevail, life is either absent altogether or it consists of poorly developed forms.” [1]

“The evidence is clear from animal experiment and human experience that if a child receives an abundance of sunlight it will thrive on almost any kind of diet, whereas, if you deprive it of sunlight, it will not thrive well on the best of diets. Sunlight is one of the most important elements of the natural diet. Every child should have sunlight before birth and after birth. No “just-as-good” substitutes should be used.” [2]

“After due consideration of the influence of light in promoting the development of animals, Trall declared that the exposure of the whole surface of the body to light is favorable to symmetrical development and offered insolation in the open air as a means of preventing and remedying rickets and scrofulous conditions.” [2]

” If sunlight is so necessary to the perpetuation of life, and the production of normal development, it is equally necessary to the preservation of health and the prevention of “disease.” if it is as necessary to life and health as are food and air, the body must inevitably be weakened and “diseased” in its absence. It fills an important need in the organism and its place cannot be filled by anything else. The highest degree of health cannot be attained and maintained without it.” [2]

Fruit bears the closest relation to light

“The best source of sugar for the body is sweet fruits–grapes, dates, bananas, figs, raisins, etc. These sugars come to us almost pre-digested and well-balanced with minerals and vitamins. These fruits are wholesome, natural, delicious and are full of life-sustaining qualities. No cook, confectioner or manufacturer can even remotely imitate these delicious products of nature’s solar-vital laboratory.

Sweet fruits are superior to starches as a source of carbohydrates. Man is a sub-tropical animal and his craving for sweets is, undoubtedly, a survival of his habit of subsisting largely on the sweet fruits which grow so abundantly in the sub-tropics and tropics. Sweet fruits serve the same heat and energy purposes that starch does and need almost no digestion. The digestion of starch foods consumes much more energy than does the digestion of sweet fruits. Dr. Densmore, indeed, strenuously advocated a non-starch dietary and insisted upon the substitution of sweet fruits for starch foods. For he claimed, and rightly, that sweet fruits give the greatest amount of nourishment for the least amount of digestive strain.”

“Fruit bears the closest relation to light. The sun pours a continuous flood of light into the fruits, and they furnish the best portion of food a human being requires for the sustenance of mind and body”.
