Tuna contains a variety of vitamins and minerals as well as other types of nutrients, including fiber. Those who want to get a lot of fiber in their daily diet will want to know that tuna does not contain a lot of it, though there is still some in this type of fish. Most of the nutritional benefits in tuna come from its protein as well as the “healthy” omega fats which can help to prevent against cardiovascular disorders and heart disease.

Diced onion is oftentimes used with tuna and this increases the amount of protein consumed by quite a bit, so you will definitely want to think about adding it in if you want more fiber in your diet. Those who have problems with constipation will certainly want to think about getting more fiber in their diet as it can help with this particular issue. There are a number of digestive benefits to consuming fiber on a regular basis, including the fact that doing so helps to prevent health problems like diarrhea as well as constipation. While these problems may not be dangerous or life-threatening, they can be quite frustrating and inconvenient at times.
