Excerpt from A Laboratory Hand-Book for Dietetics Among the recent advances in the science Of nutrition, none is more notable than the recognition of three vitamines as essential to the continued well-being of mankind, both in childhood and in adult life. It is not yet possible to speak of these systematic ally ln quantitative terms, although much knowledge has already accumulated as to their occurrence in food materials, and it is possible to grade many foods asito the relative richness or poor ness Of their yield of the different vitamines. A table has been prepared which indicates roughly the vitamine content of a number of common food materials. This table is necessarily far from complete, but it represents fairly our present state Of knowledge. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
