Explanation:

Cassandra refuses to eat vegetables and fruits, which are rich in vitamins. Vitamins play a crucial role in maintaining a healthy immune system. A deficiency in vitamins can lead to a weakened immune system, making a person more susceptible to getting sick. Fats, water, and carbohydrates do not have the same direct impact on immune system function as vitamins do in this context.

vitamins
