Celery contains valuable minerals and is soothing to the nervous system. Celery roots are rich in fat and a healing food for people with kidney, liver, and intestinal trouble. The green stalks of celery root should never be thrown away. They can be tied into a bunch and cooked with soups of meat or legumes. Celery is a very valuable food for people with a bilious temperament. ASPARAGUS. This is an easily digested vegetable and resembles celery. As a food for medicinal purposes it may be eaten raw or cooked. CARROTS AND PARSNIPS. They resemble each other, carrots being richer in sugar; the parsnip contains a little gluten. They may be eaten in the raw state with good effect. TURNIPS. Turnips contain some valuable minerals, but being rich in sugar and water, they are liable to ferment in weak stomachs, especially if eaten with lean meats, white breads or other foods, which are poor in fat. They should not be eaten in the middle of the day by people who do active work. If they disagree at night, they may be eaten for breakfast in combination with fat meats or stale bread and butter. Yellow turnips are richer in nutriment than white turnips. Raw turnips are wholesome if they agree. Never combine turnips with other starchy foods at the same meal, such as potatoes, rice, white flour preparations, apples or cucumbers. CORN. Green corn is rich in fat and protein, and can form a perfect meal during the summer if combined with tomatoes. Do not cook the corn if it is agreeable raw. Canned corn should be used with care for people with intestinal weaknesses. If used for soups it should be strained and diluted with an equal amount of hot water before thickening. TOMATO. The tomato stimulates peristalsis and is a wonderful tonic for the liver. It is one of the most perfect fruits, rich in oxalic acid and iron, and unsurpassed as a medicinal food. It contains a vegetable calomel and serves as a purifier for the liver in bilious conditions. It can be prepared and combined in many different ways. It may be one of the first articles given to a patient after an operation, serving as a food and tonic; it counteracts the sweetish taste of the chloroform and prevents fatty degeneration of the liver. Whether a food is eaten raw or cooked it is important that it be ripe. (Not ripened on the market.) For people with weak digestive organs, the best way to serve tomatoes is in the form of sterilized strained juice over toast in combination with milk or in the form of soup from canned strained tomatoes. The theory that tomatoes are liable to produce cancer is entirely unfounded. Any kind of food if eaten in excess and wrongly combined will aid in the progress of disease, but all natural foods rightly combined are wholesome if eaten according to needs of the individual. Tomatoes combine well with fatty foods,--eggs, cheese, meats and fish. LETTUCE.
