Introduction to Sardines
Sardines, commonly known as pilchards or brisling in various parts of the world, are small fish belonging to the family Clupeidae. They’re primarily found in temperate and tropical seas around the globe, particularly in the Mediterranean, Atlantic, and Pacific Oceans. Sardines have long been appreciated for their role in sustaining food supplies, especially during times when other seafood was scarce or not readily available. While they may not be everyone’s favorite, these small fish pack an incredible amount of nutritional benefits that make them an excellent choice for a healthy and balanced diet.
Nutritional Profiles
Sardines are a rich source of essential vitamins, minerals, and fatty acids that contribute to their impressive nutritional value. One 100-gram serving (about three sardines) provides approximately:
- Protein: 20 grams – Sardines offer a substantial amount of high-quality protein, which is essential for building and maintaining muscles and tissues.
- Omega-3 Fatty Acids: 1.5 grams – These healthy fats are well known for their beneficial effects on brain health, heart function, and improving overall inflammation in the body.
- Vitamin B12: 60% of the daily requirement – This essential vitamin is crucial for red blood cell formation, nervous system functioning, and maintaining a healthy metabolism.
Apart from these vital nutrients, sardines are also rich in phosphorus, potassium, selenium, and various B-complex vitamins such as thiamin (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), and pantothenic acid (vitamin B5).
