FOREWORD

One of the slogans of the World War,--"Food will win the War,"--showed
that food was much more important than many persons had believed. It
confirmed the fact that food was not merely something that tastes good, or
relieves the sensation of hunger, but that it was a vital factor in
achieving one of the noblest ideals of all time.
