One Major Effect of Eating Canned Tuna

There's truly nothing like biting into a crispy, salty, cheesy tuna melt. The toasty bread, the savory fish, the melty cheese—it's like heaven on earth in one sandwich. 

And while eating fish from a can may not seem like the healthiest thing in the world, in fact, canned tuna is one of the best (and cheapest) sources of lean protein you can buy at the grocery store.

Along with having a long shelf life (meaning you can indulge in your tuna melt craving any time it hits)

there's another major effect of eating canned tuna that your body absolutely loves, and that's the boost of omega-3 fatty acids that the fish is full of.

According to the National Institutes of Health Office of Dietary Supplements, omega-3 fatty acids are a source of polyunsaturated fat that can give your body's health a much-needed boost.

The omega-3s can help with your eye health and brain health, and can even supply your body with all-day energy. Omega 3-s contain eicosanoids, which are molecules that help with the structure

and function of your body's cardiovascular, pulmonary, immune, and endocrine health.Harvard Health points out how omega-3 fatty acids cannot be produced by the body alone.

They are an essential fat that the body needs in order to function, which you can get from foods like fish (like canned tuna), vegetable oils, nuts, flax seeds, flaxseed oil, and leafy greens.

Omega-3 fatty acids also help with the cell membranes in your body which, according to Harvard Health, result in hormones that can help regulate "blood clotting, contraction

and inflammation." Omega-3 fatty acids are anti-inflammatory, meaning they can help with preventing cardiovascular diseases as well as lupus, eczema, rheumatoid arthritis, and even cancer.

 Dietary fats are an essential part of your diet because it helps with digestion and your body's fullness, while also providing your body with energy throughout the day.

Canned tuna is obviously a great source of omega-3 fatty acids that you can add to your diet for a relatively cheap price.

An article published by the USDA Agricultural Research Service says it's important to eat at least 250 milligrams of omega-3's per day, which equates to 2 grams of omega-3's a week.

A 3-ounce serving of albacore tuna contains 1.5 grams of omega-3 fatty acids. If you're eating at least one canned tuna a week, you'll be getting all the omega-3 fatty acids you need.
