Dora Roper's book, Food for the Traveler, was published in 1916 and it was a bit ahead of her time.
This book is full of how vegetables are better for you than meat, taking good physical care is important, and you also need meditation time to feed your soul. Physical, mental and emotional are all tied together (uhm, yes, that is true). But everything should be done in moderation. And some people have special dietary needs (ie: allergies or intolerances) that have to be taken into account, even back then, which I am sure happened.
I did not care for this book. Mostly due to the content. Interestingly as it was, she sounded like a quack. The writing style was fine, easy to follow. No formatting problems that stood out. Good for those who want to live a more 'pure' life with a early 1900's twist. I wonder how well received this was when it was first released back when.
