Lethbridge Herald, The (Newspaper) - October 15, 1974, Lethbridge, Alberta Vitamin C: More warnings that high consumption may be dangerous NEW YORK (AP) New warnings against the use of high doses of Vitamin C for the common cold have emerged from an international meeting here on research into the vitamin. "To recommend now for the general public to take high doses of Vitamin C over and above those recommended by the (U.S) National Academy of Sciences would be said Dr. Myron Winick of the Institute of Human Nutrition at Colum- bia University, New York. Vitamin C may indeed have an effect on the common cold, Winick said in an interview, but the effect is too small to justify high doses in view of the lack of knowledge of possible ill effects, such as in pregnancy or on a fetus. Dr. Linus Pauling, two-time winner of the Nobel Prize in medicine, has stimulated wide interest in Vitamin C with his highly-publicized recommenda- tions for high doses to combat the common cold. A key study that has been cited in support of Pauling's ideas was conducted at the University of Toronto and indicated that the intake of one gram (one DR. LINUS PAULING 28th of an ounce) a day and four grams a day when ill produced a 30-per-cent reduction in days-off work due to cold symptoms. But Dr. Terence Anderson of the University of Toronto, who conducted the study, told the meeting that subsequent studies showed that such high doses are not necessary to produce a useful reduction Perhaps; 100 or 200 milligrams a day would be suf- ficient, Anderson said. Pauling has recommended a routine daily intake of to milligrams or one to 10 grams of Vitamin C. The recommended daily allowance, of the Food and Nutrition Board of the U.S. National Academy of Sciences-National Research Council, is 50 to 60 milligrams for an adult. "In Anderson reported, "I would suggest that unless and until firm evidence is forthcoming that higher doses of Vitamin C are more effective, we should adhere to the principle of 'primum non and advise the public to limit their daily intake to 100 or 200 milligrams, except possibly for brief periods during acute infection when gram doses may be beneficial." The Latin "primum non first not to injure, is used in medicine to mean that the first rule for a doctor is not to do anything in treating a patient that would injure the patient. 'LOUSY FOR SOCIETY' Winick, a session chairman at the meeting Wednes- day through Saturday, sponsored by the New York Academy of Sciences and the nutrition institute at Columbia, said another factor in Vitamin C usage is that it may be affecting only the symptoms of the cold, not the infection itself. This would be fine for the individual, Winick said, but if the person who is still infectious returns to work or school and spreads the infection, this is "lousy for society." Anderson and others agreed with this point. The scientists also agreed that the Pauling com- ments on Vitamin C had led to a great deal of new research. "If his objective was to provoke research in this Winick said, "he really accomplished it One of many new this by researchers at the Roche Research Centre in Nutley, is that Vitamin C, in the laboratory, prevents the formation of cancers produced by the reaction of sodium nitrite with substances in the stomach. "Sodium nitrite is used in meat processing to suppress the outgrowth of botulmim bacteria and to impart characteristic flavor and color to cured meat the researchers said. "Thus, it is of considerable importance to eliminate or significantly reduce the potential threat to human health imposed by man's ingestion of nitrite and amines. But the Roche scientists concluded: "The significance of .these findings with respect to protecting man from exposure to nitrosamines in his environment is yet to be established."
