Carefully observe those articles of food which you find injurious, and avoid them. Observe, also, as nearly as you can, the _quantity_ which agrees with your stomach, and see that you never exceed it. Take no food between your regular meals. The stomach is employed from three to five hours in digesting a meal; if more food is taken during that time, it disturbs and impedes digestion, and makes it more laborious. And, after one meal is digested, the stomach needs rest before another is taken. In connection with these general hints, attention to the two following rules will generally be sufficient: (1.) Avoid highly seasoned food, fresh bread, heating condiments, and stimulating drinks. (2.) Select the simplest dishes, and make your meal of a single course. Mixed dishes are more likely to be injurious; and a second course will almost certainly lead to excess. But, do not give your attention so much to this subject as to become _splenetic_. The imagination has a great influence upon animal feeling; and if you are always watching the digestion of your food, you will be sure to find dyspeptic symptoms; and if you humor your stomach too much, you will weaken its capacity of accommodating itself to the kind of nutriment it receives. Having fixed your principles of regimen, adhere to them as rigidly as you can without inconvenience to others; but having done this, let your mind dwell as little as possible on the subject, and do not make it a matter of frequent conversation. Especially, do not make trouble to the friends who entertain you, when away from home, by excessive particularity. You may find some wholesome dish on the most luxurious table; and if the table is _lean_, you need not fear.
