SEVENTH TALK 119 matter of food values. I know there is a disposition to think that people who pay too much attention to food are worrying themselves unnecessarily about purely physical things. Certainly I would say, do not overdo the thing; take the middle path and be wise. But you owe it to your body to find out what it can take and what amount of that suits it best. It is quite easy to find out by taking a little trouble and making experiments. There are many books on that subject. Dr. Kingsford's Perfect Way in Diet I knew many years ago, but any of the much later books on the subject would tell you what amount and what proportion of different kinds of food are needed, how much of the flesh-forming, bone-forming, and blood-forming foods are necessary, carbohydrates, proteids, etc. Any of those books will tell you, and they will give you long lists of foods which will show you what to eat. Very likely there may be only one or two^ that may suit your particular body. Find out what those are and live principally on them. You, I take it, have all been following the' perfect diet—the vegetable food. You may or may not have had some trouble in coming to it from earlier habits. I know very well in England, when people begin to be vegetarians, they usually misunderstand the whole business. They have been living principally on meat with cabbage and potatoes. Their idea of being vegetarians is to give up meat and live on cabbage and potatoes.
