What Does Calcium Do in the Body - Nutrition Tutorial Series

Calcium Overview


Calcium is found in plant and animal foods. It is the most abundant mineral found in the body. Almost all of the calcium in the body is found in the bones and teeth.


Health Benefits of Calcium


Calcium is essential for strong bones and teeth. It is also necessary for muscle contraction, including a regular heartbeat. Calcium helps control blood pressure and helps prevent colorectal cancer. Calcium is also needed for proper blood clotting, nerve function and lowering cholesterol.


Calcium Deficiency Symptoms


Inadequate intake of calcium can result in osteoporosis. The body requires calcium and when it is deficient, the body will look wherever it can to find the calcium it needs, which is mainly the bones and teeth. The bones and teeth will then lose calcium, leading to osteoporosis. Calcium deficiency can also lead to muscle cramps, arm and leg numbness or tingling, joint pain, slow pulse, heart palpitations, cavities, insomnia or irritability. In children, a calcium deficiency can cause deformed bones, a disease called rickets.


Foods Rich In Calcium


Calcium is found only in both plant and animal foods. PLant sources of calcium include chia seeds, flaxseed, almonds, soybeans, filberts, brazil nuts,collard greens, kale, mustard greens, Great Northern beans, navy beans, tofu and broccoli. Fruits containing calcium include oranges, tangerines, dried apricots, rhubarb, kiwi, strawberries, limes, blackberries, lemons, raspberries, red grapefruit, papaya and guava. Animal sources of calcium include milk, yogurt, cheese and cottage cheese. Blackstrap molasses is also a very good source of calcium.
