Oily fish are nutritional superstars and if you want to buy local, you won’t do better than mackerel, which is abundant in our waters in early summer. Here’s why it’s a good catch.
1/ One 100g serving contains more than 1,000mg of omega-3 fatty acids, which reduce inflammation and lower the risk of cardiovascular disease.
2/ It’s a fantastic source of vitamin B12 (100g contains three times the daily requirement), integral to the production of oxygen-carrying red blood cells. It’s also rich in the antioxidant mineral selenium. A 100g fillet provides three quarters of your daily needs.
3/ A small mackerel fillet (100g) contains 24g of protein. In a study involving mice, the protein derived from mackerel was found to delay fatigue during endurance exercise.
4/ Research has shown that the two most potent forms, of omega-3s, EPA and DHA, are better absorbed from fish than from fish oil supplements.
