1. Sardines are rich in omega-3 fatty acids. Eating foods high in omega-3 fatty acids is linked to numerous health benefits. According to the book, The 150 Healthiest Foods on Earth: The Surprising, Unbiased Truth about What You Should Eat and Why, "Epidemiologic studies in the United States report that a mere 1/2 gram a day of these fats can significantly decrease cardiovascular risk. Omega-3s help with mood, thinking, circulation, and glucose and insulin metabolism; they lower blood pressure; and they protect against heart disease."
2. Sardines are rich in calcium. Not only is calcium essential for strong bones and teeth, it's also important for your muscles, blood clotting, and nervous system. It also plays an important role in the release of hormones. Not getting enough calcium can lead to weakened bones and an increased risk of osteoporosis.
3. Sardines are a good source of selenium. Selenium is an important cancer-fighting mineral.
