Explanation:

The barber is a human being and like every other human being, he needs a balanced diet that includes fruits and vegetables.

Why the Barber Needs More Fruits:

1. Nutrients: Fruits are rich in essential vitamins and minerals. They contain important nutrients like Vitamin C, Vitamin A, potassium, and fiber that are necessary to maintain good health.

2. Energy: Fruits are an excellent source of natural energy. They are low in calories and high in fiber, which makes them a perfect snack for people who want to maintain a healthy lifestyle.

3. Digestion: Fruits are easy to digest and help in regulating digestion. They contain powerful enzymes that help in breaking down food.

4. Immune system: Fruits are known to boost the immune system. They help in fighting off infections and diseases.

Why Not Vegetables or Gold Coins:

1. Vegetables: While vegetables are also important for a balanced diet, the question specifically asks for what the barber wants more. Therefore, we can assume that the barber already has enough vegetables in his diet and wants to add more fruits.

2. Gold coins: Gold coins cannot provide the barber with the essential nutrients that fruits can. While they may be valuable, they cannot be consumed and do not contribute to a healthy lifestyle.

In conclusion, the barber wants more fruits because they are a rich source of essential nutrients, provide natural energy, aid in digestion, and boost the immune system.
