Nutrition Quotes (15 quotes)

A library … is a great catalyser, accelerating the nutrition and rate of progress in a profession.
Address for the Dedication of the New Building of the Boston Medical Library (12 Jan 1901). Printed as 'Books and Men', The Boston Medical and Surgical Journal (17 Jan 1901), 144, No. 3, 60.

Food may be defined as material which, when taken into the body, serves to either form tissue or yield energy, or both. This definition includes all the ordinary food materials, since they both build tissue and yield energy. It includes sugar and starch, because they yield energy and form fatty tissue. It includes alcohol, because the latter is burned to yield energy, though it does not build tissue. It excludes creatin, creatininin, and other so-called nitrogeneous extractives of meat, and likewise thein or caffein of tea and coffee, because they neither build tissue nor yield energy, although they may, at times, be useful aids to nutrition.
Methods and Results of Investigations on the Chemistry and Economy of Food, Bulletin 21, US Department of Agriculture (1895). Quoted in Ira Wolinsky, Nutrition in Exercise and Sport (1998), 36.

Forests and trees make significant direct contributions to the nutrition of poor households ... [as] rural communities in Central Africa obtained a critical portion of protein and fat in their diets through hunting wildlife from in and around forests. The five to six million tonnes of bushmeat eaten yearly in the Congo Basin is roughly equal to the total amount of beef produced annually in Brazil – without the accompanying need to clear huge swathes of forest for cattle.

I've been very involved in science literacy because it's critically important in our world today. … As a public, we're asked to vote on issues, we’re asked to accept explanations, we're asked to figure out what to do with our own health care, and you can't do that unless you have some level of science literacy. Science literacy isn’t about figuring out how to solve equations like E=MC². Rather, it's about being able to read an article in the newspaper about the environment, about health care and figuring out how to vote on it. It's about being able to prepare nutritious meals. It's about being able to think your way through the day.
As quoted in 'Then & Now: Dr. Mae Jemison' (19 Jun 2005) on CNN web site.

It is a fair question whether the results of these things have induced among us in a large class of well-to-do people, with little muscular activity, a habit of excessive eating [particularly fats and sweets] and may be responsible for great damage to health, to say nothing of the purse.
L.A. Maynard citing Wilbur O. Atwater in a biographical sketch, Journal of Nutrition (1962) 78, 3. Quoted in Ira Wolinsky, Nutrition in Exercise and Sport (1998), 36.

On the 20th of May 1747, I took twelve patients in the scurvy, on board the Salisbury at sea. Their cases were as similar as I could have them. They all in general had putrid gums, the spots and lassitude, with weakness of their knees. They lay together in one place, being a proper apartment for the sick in the fore-hold; and had one diet common to all, viz, water-gruel sweetened with sugar in the morning; fresh mutton-broth often times for dinner; at other times puddings, boiled biscuit with sugar, &c.; and for supper, barley and raisins, rice and currents, sago and wine, or the like.
Two of these were ordered each a quart of cider a-day. Two others took twenty-five gutta of elixir vitriol three times a-day, upon an empty stomach; using a gargle strongly acidulated with it for their mouths. Two others took two spoonfuls of vinegar three times a-day, upon an empty stomach; having their gruels and their other food well acidulated with it, as also the gargle for their mouth. Two of the worst patients, with the tendons in the ham rigid, (a symptom none of the rest had), were put under a course of sea-water. Of this they drank half a pint every day, and sometimes more or less as it operated, by way of gentle physics. The others had each two oranges and one lemon given them every day. These they eat with greediness, at different times, upon an empty stomach. They continued but six days under this course, having consumed the quantity that could be spared. The two remaining patients, took the bigness of a nutmeg three times a-day, of an electuary recommended by an hospital-surgeon, made of garlic, mustard-seed, rad. raphan. balsam of Peru, and gum myrrh; using for common drink, barley-water well acidulated with tamarinds; by a decoction of which, with the addition of cremor tartar, they were gently purged three or four times during the course.
The consequence was, that the most sudden and visible good effects were perceived from the use of the oranges and lemons; one of those who had taken them, being at the end of six days fit for duty. …
Next to the oranges, I thought the cider had the best effects.
A Treatise of the Scurvy (1753), 191-193. Quoted in Carleton Ellis and Annie Louise Macleod, Vital Factors of Foods: Vitamins and Nutrition (1922), 229-230.

One of the commonest dietary superstitions of the day is a belief in instinct as a guide to dietary excellence ... with a corollary that the diets of primitive people are superior to diets approved by science ... [and even] that light might be thrown on the problems of human nutrition by study of what chimpanzees eat in their native forests. ... Such notions are derivative of the eighteenth-century fiction of the happy and noble savage.
Nutrition and Public Health', League of Nations Health Organization Quarterly Bulletin (1935) 4, 323–474. In Kenneth J. Carpenter, 'The Work of Wallace Aykroyd: International Nutritionist and Author', The Journal of Nutrition (2007), 137, 873-878.

Real knowledge goes into natural man in tidbits. A scrap here, a scrap there; always pertinent, linked to safety or nutrition or pleasure. Human curiosity survives and is catered for, by the twopenny weeklies, 24 lines on chromosomes, six lines on a three-headed calf.
From Culture (1938). Reprinted as Guide to Kulchur (1952, 1970), 99.

The cause of nutrition and growth resides not in the organism as a whole but in the separate elementary parts—the cells.

The energy liberated when substrates undergo air oxidation is not liberated in one large burst, as was once thought, but is released in stepwise fashion. At least six separate steps seem to be involved. The process is not unlike that of locks in a canal. As each lock is passed in the ascent from a lower to a higher level a certain amount of energy is expended. Similarly, the total energy resulting from the oxidation of foodstuffs is released in small units or parcels, step by step. The amount of free energy released at each step is proportional to the difference in potential of the systems comprising the several steps.
'Oxidative Mechanisms in Animal Tissues', A Symposium on Respiratory Enzymes (1942), 22.

The interactions of man with his environment are so complex that only an ecological approach to nutrition permits an understanding of the whole spectrum of factors determining the nutritional problems that exist in human societies.

The situation with regard to insulin is particularly clear. In many parts of the world diabetic children still die from lack of this hormone. ... [T]hose of us who search for new biological facts and for new and better therapeutic weapons should appreciate that one of the central problems of the world is the more equitable distribution and use of the medical and nutritional advances which have already been established. The observations which I have recently made in parts of Africa and South America have brought this fact very forcible to my attention.

There is no existing ‘standard of protein intake’ that is based on the sure ground of experimental evidence. ... Between the two extremes of a very high and a very low protein intake it is difficult to prove that one level of intake is preferable to another. ... Physiologists, in drawing up dietary standards, are largely influenced by the dietary habits of their time and country.

“True is it, my incorporate friends,” quoth he, “That I receive the general food at first, Which you do live upon; and fit it is, Because I am the storehouse and the shop Of the whole body. But, if you do remember, I send it through the rivers of your blood, Even to the court, the heart, to th’ seat o’ th’ brain; And, through the cranks and offices of man, The strongest nerves and small inferior veins From me receive that natural competency Whereby they live. And though that all at once”— You, good friends, this says the belly, mark me.
[Told as a fable, this is the belly’s answer to a complaint from the other members of the body that it received all the food but did no work.] In Coriolanus (1623), Act 1, Scene 1, line 130-141. Webmaster’s note: The Fable of the Belly has its roots in antiquity. William Harvey delivered a lecture in Apr 1616 on his discovery the circulation of blood in the body, but did not publish until 1628.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
