Tuna

A health website claims that eating tuna can avoid vitamin B12 deficiency. The fish contains this essential vitamin in “high concentrations”, said Healthline, “and 100 grams of fresh tuna contains almost 160% of your daily vitamin B12 requirement”.

Tuna is a popular fish that provides a variety of nutrients, including protein, vitamins, and minerals. It has large levels of vitamin B12, particularly in the dark muscles, which are located just beneath the skin. Cooked tuna contains 453% of the daily value (DV) for the vitamin in a 3.5-ounce (100-gram) serving. In addition to lean protein, phosphorus, selenium, and vitamins A and B3, this same serving size is high in lean protein, phosphorous, selenium, and vitamins A and B3. Tuna in a can also has a good level of vitamin B12. In fact, a can of light tuna canned in water (142 grams) contains 152% of the daily requirement.
