Explanation:

Old age starts around 65 years old, but many factors influence the speed and intensity of the aging process. Among these we can mention the food. We all need to have a balanced diet, but this factor is even more important in the elderly, as their bodies have a harder time retaining vitamins and nutrients, and the elderly are more likely to experience the effects of a nutrient deficiency.

For this reason, it is important for the elderly to have a balanced diet, which provides all the nutrients in adequate amounts to the body. If the elderly do not have a balanced diet, they should take vitamin supplements to reduce the harmful effects of nutrient deficiencies. Salvatore is a senior who follows a well-balanced diet, so we can say that he will not need to take vitamin supplements.
