Is Canned Tuna Bad For You?

You may have heard that all processed food is bad, but that’s just not true. For instance, people in Henderson, Nevada can get a healthy protein option by using canned tuna. However, there are some reasons that this healthy food could also be bad for you. If that sounds confusing, let’s take it one step at a time. Tuna is a healthy source of protein. It has a long shelf life and has few additives. The ingredients can be as simple as tuna, oil or water and a bit of salt, to canned tuna with a lot of additives. Read the label and opt for the ones that have the least ingredients.

Water packed vs oil packed tuna.

If you’ve looked on the grocery shelf for tuna, you’ll find all types from chunk light tuna, albacore, yellowfin—also called ahi, skipjack, packed in water, packed in oil, packed in water with salt added. It can all be very confusing. Which is better for dietary needs, particularly if you’re trying to lose weight? It’s the water packed tuna, which has 42 grams of protein, but only 191 calories for a can. The oil packed for the same amount has 339 calories with approximately the same amount of protein.

Tuna provides a healthy option and many nutrients.

Tuna is high in omega-3 fatty acids that are important for good health. They’re heart healthy and aid in preventing macular degeneration. Eating tuna can help you lower your blood pressure because it’s rich in potassium. The zinc, manganese, vitamin C and selenium make it rich in antioxidants to boost your immune system. Eating it regularly helps prevent stroke, improve skin health and strengthen bones.

Watch out for mercury.

One of the biggest problems with eating tuna regularly is the potential for consuming high amounts of mercury. Water contamination often makes this heavy metal more prevalent in fish. It can cause health problems in humans, which include impairing the central nervous system. Tuna eats smaller fish, which may be contaminated with mercury, then it collects in the tissues of the tuna. The amount varies by species. Tuna, more than other kinds of fish, such as salmon or tilapia, may have a high concentration. As a rule of thumb, larger species of tuna have a higher amount of mercury than smaller species, like light tuna or skipjack. Canned tuna tends to have less mercury content than fresh or frozen tuna.

  • You can still consume tuna, just limit the amount eaten to one four-ounce serving a week or opt for the tuna that has a lower mercury content. Consider eating light or skipjack. Pregnant women should avoid tuna.
  • Tuna contains a protein called elastin that helps keep the skin youthful and smooth. It’s necessary for repairing skin tissue.
  • Tuna contains potassium, which is necessary for the functioning of kidneys. Keeping the kidneys functioning properly can also aid in preventing kidney cancer. Tuna also contains nutrients to fight other types of cancer.
  • Tuna helps you lose weight. It also has nutrients, like B vitamins, high protein content and omega-3, that boost your metabolism and energy. It’s high protein content helps you build muscle tissue, too.
