All who leave the land of their birth should make themselves acquainted with the art of living and the peculiarities of the new country in which they intend to live.

To depart entirely from their old customs and habits is as dangerous as to neglect the study of the new environment or the failure to adopt necessary changes.

In some States the climatic conditions of the United States are very changeable; we have extreme heat and cold, and excess of rain with wind storms and dryness changing within a short time. West of the Rocky Mountains we have a mild sea air. In the Southern States and near the Pacific Coast we have low districts where malaria and catarrhal conditions are easily acquired.

Tropical fruits and vegetables which are looked upon as luxuries in Northern Europe are necessary articles of food in the country where they grow, therefore the stranger should make himself acquainted with such foods and by degrees learn to eat them.

In countries where the days are extremely hot and the nights are cold, the selection of foods should be made accordingly. Fats produce more than twice the amount of energy than carbo-hydrates, therefore they are more suitable during the early part of the day. During the middle of the day select foods of the protein class, in proper proportion with fruits and raw greens. For the evening meal use the stimulating sub-acid and sweet fruits in combination with light protein and cereal foods.
