Another food that contains a ton of calcium and can help if you are suffering from hyperparathyroidism is cheese. The great thing about cheese is it is also high in protein and offers a great snack. There are so many varieties of cheese from which to choose, which makes it easy to add this to your diet. You can add some cheese to some of your favorite dishes to get a boost of calcium. In addition, cheese really does add some flavor to your meals. A snack of cheese and whole-grain crackers can keep you full for a long time. It is important to make sure that you do not overdo it on the cheese and you should be choosing healthier low-fat cheeses to snack on because too much fatty cheese can cause weight gain and also constipation, so just do not go overboard.
