How to Choose the Best Tuna?

While tunas are chock-full of important nutrients, it is still best to make sure that you are getting only the best quality ones to reap its maximum benefits to your health. Here are some tips on choosing the best tuna:

Fresh Tuna

If you're sushi or grilled steak lover, fresh tuna may be your best bet. Take note, though, that the most important consideration in your purchase is the size of the fish and its mercury content.

Keep in mind this general guideline: The bigger the fish, the higher its mercury content. Among the bigger types that contain high amounts of mercury are albacore, bigeye, and yellowfin.

Experts say a person weighing 150 pounds can avoid exposing himself or herself to excessive and potentially dangerous amounts of mercury, by limiting the intake of bigeye tuna to 2 ½ to 3 ounces per week.

Canned Tuna

Canned tuna may either be packed with oil or water. While both taste delicious, especially the fancier imported ones, it is ideal to choose canned tuna in water. Why?

Canned tuna in oil is three times fatter and fewer in calories compared with its water-packed counterpart. They make a great addition for smaller servings, though, such as in salads to be shared with guests.

But if your taste preference dictates canned tuna in oil, it will help to drain some of the oil off.

What are the Potential Risks of Eating Tuna?

Due to the high amounts of mercury contained in some fish like tuna, pregnant or breastfeeding women, and young children are strongly advised to limit consumption to 12 ounces of seafood per week.

Canned tuna (skipjack) is considered safer for consumption, but at-risk people may need to take lower amounts of certain tuna species.

Takeaway

Canned or fresh, tuna surely has something valuable to offer for your health! Just make sure that you are taking it in appropriate amounts to avoid mercury toxicity.

Also, if you have certain health concerns or are taking certain medications, it is best to seek advice from your doctor first if tuna can be a part of your diet. Otherwise, enjoy it and its health perks!
