Tuna is a very nutritious substance for everyone, including children. Fish is a very nutritious element that is essential for human growth and is an excellent food to strengthen the immune system.
Fish canned foods contain many vitamins and minerals, including phosphorus, calcium, iron, fluoride and iodine, which are very important for human health, especially for children. The iodine in canned fish plays an important role in preventing mumps and also plays an important role in increasing children's intelligence. That's why eating tuna is highly recommended for students, especially on exam days, because tuna increases brain function.
