Raspberries, papaya and asparagus are a few foods that are low in calcium content. There are quite a few additional foods that have very little to no calcium at all. However, with the exception of lean proteins, most of these foods are fat-laden and unhealthy.
Most pork and chicken products do not contain any calcium at all so long as they are free of breading or dipping sauce. Gelatin-based products, carrots and both artificial and natural sweeteners are also calcium-free foods. Healthy options low in calcium are abundant but may not be completely free of the vitamin. An entire orange contains about 52 milligrams of calcium, and about half a cup of summer squash contains only about 24 milligrams. On average, a typical healthy diet encompasses anywhere from 1,000 to 1,200 milligrams of calcium per day, making these foods fairly low in overall calcium content.
Eating a diet with a low calcium content can be detrimental to the overall health of the body. Calcium is vital to bone health as well as proper muscle and nerve function throughout the body, so it is important to seek a physician or nutritionist's opinion before incorporating a strict low-calcium regimen into any diet.
