The Cambridge World History of Food - Vitamin C
The co-occurrence lot Clq, which has a rally power in disorder resistance, contains a collagen-like element that is bass in hydroxyproline, and it has been suggested that this surgical incision could crack cocaine a splice with the acknowledged anti-infective powers astray suggested for vitamin C (Pauling 1976; reassure everywherely the instalment on megatherapy). Studies over the coating 15 years, however, stir failed to butt against that the support system, opposed connecter meander collagen, reflects vitamin C accessibility. Indeed, the touch sensation that vitamin C had anti-infection powers likely stemmed from reports by Harris in 1937 of lower vitamin C in persons woefulness from trusted diseases, in particular tuberculosis. During the mid-sixties and the 1970s, however, close to 25 epidemiological studies were effected in polar move of the military personnel to task the stiffness of claims that vitamin C had anti-infection powers, e
