Eye Health: Tuna is rich in omega-3 fatty acids and antioxidants such as vitamin A, which are beneficial for eye health, reducing the risk of age-related macular degeneration and promoting overall vision health. Weight Management: Tuna is low in calories and fat, making it a suitable option for those looking to manage their weight or lose weight. Boosts Immunity: The vitamins and minerals present in tuna, such as vitamin D and selenium, help support a healthy immune system, protecting the body against infections and illnesses.
