Ginger Tuna Ceviche

Ginger Tuna Ceviche

The health benefits of omega-3 fatty acids, particularly the DHA and EPA varieties, are well documented and becoming well known.1 An estimated 17 percent of US adults consume fish oil supplements and since 2007, US fish oil sales have surged from $425 million to over $1 billion.2,3 While these figures are encouraging, more attention should be placed on omega-3 quality.

Because of their unique molecular structures, polyunsaturated fatty acids, including omega-3, are prone to oxidation.4 Heat, light, and oxygen can quickly degrade them, giving rise to harmful free radicals. Fish oil products vary considerably, but excessive oxidation is not uncommon.5

In general, whole fish provides better quality (less oxidized) omega-3 than extracted fish oils. Taking it one step further, raw fish provides better quality omega-3 than cooked fish. This doesn’t mean cooked fish is bad, but when raw fish opportunities present themselves, you shouldn’t hesitate. When your local supermarket has ultra-fresh tuna, mackerel, or wild salmon, for example, buy some and prepare a simple, delicious ceviche.

Ceviche hails from the coastal regions of Central and South America. Recipes vary, but most feature fresh fish, shrimp, squid, or other seafood marinated in citrus juices. Our recipe works for fatty fish and whitefish alike, but the kick of ginger pairs especially well with tuna. If you’re making ceviche with a stronger tasting fish like mackerel, you’ll want to add some diced onions and possibly forgo the ginger.
