The Best Freezer Containers for Heart-Healthy Ingredients

I think of my freezer as a kitchen tool. It’s there to make life easier, whether I’m stockpiling batches of sauce, storing preserves for the winter or stowing leftovers to save some money. On top of that, I always keep a few key ingredients in my freezer, so that I have them on hand when I need them. In fact, I plan on adding four heart-healthy foods to my freezer as soon as I make my next grocery run.

A cardiologist confirmed to us that frozen berries, spinach, salmon and edamame are some of the best items you can eat for heart health. Why? Berries contain an abundance of antioxidants to help reduce inflammation; spinach is high in nitrates, which can help reduce blood pressure,; salmon is packed with healthy omega-3 fatty acids and minimal saturated fat; and edamame contains fiber, protein, potassium and antioxidants. All four of these foods keep incredibly well in the freezer, too

With these staples in your meal rotation, you’re improving your cardiovascular health in the long term. But, to be quite frank, the packaging the ingredients come in leaves a lot to be desired. Luckily, alternative storage options abound. With the right containersgone are the days of ice-damaged berries and edamame that tastes like my freezer. Luckily, we did the work for you—and after rigorous testing, these OXO containers proved to be the absolute best glass freezer containers on the market.
