So much good advice is already given about what and how to eat, I need say nothing here, and even without that advice, which in itself is so truly valuable, most of us could have plain common sense about our own food if we would use our minds intelligently about it, and eat only what we know to be nourishing to us.

That can be done without fussing.

Fussing about food contracts the stomach, and prevents free digestion almost as much as eating indigestible food.
Then again, if we deny ourselves that which we want and know is bad for us, and eat only that which we know to be nourishing, it increases the delicacy of our relish.

We do not lose relish by refusing to eat too much candy.

We gain it.
