Calcium is an essential mineral for maintaining healthy bones and teeth, supporting muscle function, and regulating heart and nerve activity. However, not all foods contain calcium. Below is a list of foods that are considered to be calcium-free, meaning they contain little to no calcium that can be absorbed by the body.
Fats and Oils
Fats and oils are generally devoid of calcium. Some common examples of calcium-free fats and oils include:
- Beef and chicken fat
- Vegetable shortening
- Saffola margarine
- Canola oil
- Corn oil
- Olive oil
- Peanut oil
- Safflower oil
- Soybean oil
- Sunflower oil
- Regular ranch dressing
- Imitation low-calorie mayonnaise
Fruits and Vegetables
While most fruits and vegetables are good sources of calcium, there are a few that are specifically identified as having no calcium. These include dried cranberries and artichoke hearts, which are usually preserved in water or marinated.
Meats, Nuts, and Seeds
All types of meats, nuts, and seeds containé’™, with the notable exception ofoctopus, salmon, swordfish, and mackerel. Those with the lowest amounts of calcium include:
- Octopus (4 oz, 7 mg)
- Salmon (4 oz, 8 mg)
- Raw swordfish (4 oz, 5 mg)
- Bluefin tuna (4 oz, 9 mg)
- Dried and cured beef (1 oz, 1 mg)
- Bottom round lean beef roast (4 oz, 6 mg)

Grain Products
Grain products are generally not high in calcium, with the notable exception of cornbread, which contains about 7 mg of calcium per cup.
Low-Calcium Vegetables
Some low-calcium vegetables have less than 100 milligrams of calcium per cup. These include:
- Bok choy: 40 milligrams
- Chicory: 40 milligrams
- Collard greens: 50 milligrams
- Corn: 10 milligrams of calcium in a cup
- Dandelion greens: 80 milligrams

Risks Associated with Calcium
While calcium is crucial for health, an excessive amount can lead to certain issues. The National Institutes of Health has linked excess calcium to constipation, iron and zinc deficiencies, and an increased risk of heart disease and prostate cancer. It's important to maintain a balanced intake of calcium to avoid these problems.
Hypercalcemia and Calcium-Rich Foods
Hypercalcemia is a condition where there's too much calcium in the blood. It can weaken bones and cause kidney stones, heart problems, and affect brain function. High-calcium foods include dairy products like cheese, milk, cream, and yogurt. Seafood, nuts, and seeds also contain high amounts of calcium. People with hypercalcemia should avoid these foods to prevent worsening their condition.
##, while calcium is vital for overall health, not all foods contain this mineral. By incorporating calcium-free foods into your diet, you can manage your calcium intake and avoid potential health risks associated with an excess of calcium.
