The elderly, weak, and young can also benefit greatly from tonic foods, especially during the winter. Some foods, such as goat meat and spinach, are seen as "hot", while others, such as Chinese cabbage and radish, are seen as "cold." One should be careful not to eat too much of either "hot" or "cold" food. However, how much "hot" or "cold" food one should eat depends on the time of the year, how the food is prepared and what it is prepared with, and the individual's health.
