This verse has caused some to ask if meat should be eaten in the summer. Meat has more calories than fruits and vegetables, which some individuals may need fewer of in summer than winter. Also, before fruits and vegetables could be preserved, people often did not have enough other food to eat in winter. Spoiled meat can be fatal if eaten, and in former times meat spoiled more readily in summer than winter. Modern methods of refrigeration now make it possible to preserve meat in any season. The key word with respect to the use of meat is "sparingly".
