Health Benefits of Tuna

Hear the word “tuna” and you probably instantly think healthy. And rightfully so! Not only is it considered one of the best sources of vitamin D, it’s also packed with iron, vitamin B6, potassium, and iodine. You can get 50% of the daily recommended level of vitamin D in just 1 can of tuna. This is super important when it comes to bone health, boosting your immune system, and helping kids reach optimal growth. 

Fortunately, with a mercury limit that’s ten times stricter than the FDA standards, it’s easier than ever to get your hands on tuna that even pregnant mothers and kids can eat with gusto.

Benefits of Sauerkraut

Fermented cabbage. As an old Chinese practice, fermenting foods was mainly done to keep foods from spoiling. However, it would later become known that there are many benefits to fermentation. One of them being packed with probiotics. 

Similar to tuna, sauerkraut provides lots of nutritional value in the form of fiber, carbs, vitamins A, C, and K, as well as iron, folate, and magnesium. It’s no wonder why combining tuna with sauerkraut is such a healthy choice!

Make a full meal of your tuna melt and enjoy it with a warm bowl of  Garden Tomato Soup. Tuna melts can be made quickly and served often. Although they’re best served immediately after cooking, you can also fix it for lunch the next day and simply reheat it slowly on medium to low heat! Enjoy!
