Calcium is an essential nutrient that is well-known for its role in building and maintaining strong bones. But did you know that calcium may also play a role in reducing the risk of certain cancers?.
What is Calcium?
Calcium is a mineral that is essential for many bodily functions. In addition to building and maintaining strong bones, calcium is also important for muscle function, nerve function, and blood clotting.
The body is not able to produce calcium on its own, so it must be obtained through the diet.
The Benefits of Calcium
Calcium is best known for its benefits in building and maintaining strong bones. Adequate calcium intake is important throughout life, but it is especially important during childhood and adolescence when bones are growing rapidly.
Without enough calcium, bones may become weak and porous, which can lead to osteoporosis later in life.
In addition to its role in bone health, calcium may also have other health benefits. Some research suggests that adequate calcium intake may play a role in preventing certain types of cancer.
Calcium and Cancer Risk
Several studies have found that people with higher calcium intake may have a lower risk of developing certain types of cancer.
For example, studies have found that people who consume higher amounts of calcium have a lower risk of developing colorectal cancer, breast cancer, and ovarian cancer.
The exact reason for this association is not completely understood, but there are a few theories. One theory is that calcium may help to reduce the growth of cancer cells.
Calcium is known to regulate cell growth and differentiation, which may help to prevent cancerous cells from growing and spreading. Additionally, high levels of calcium in the body may trigger certain processes that help to kill off cancer cells.
Another theory is that calcium may help to reduce the risk of cancer by binding to harmful compounds in the gut. Certain compounds in the gut can promote cell growth and increase the risk of cancer.
Calcium may bind to these compounds and help to prevent their harmful effects.
How Much Calcium is Enough?
The amount of calcium you need each day depends on your age and sex. The recommended daily intake of calcium is as follows:.
- Children ages 1-3: 700 milligrams per day
- Children ages 4-8: 1000 milligrams per day
- Children ages 9-18: 1300 milligrams per day
- Adults ages 19-50: 1000 milligrams per day
- Adults over age 50: 1200 milligrams per day
Calcium can be obtained through the diet or through supplements. Dairy products such as milk, cheese, and yogurt are good sources of calcium.
Other sources of calcium include leafy green vegetables, canned fish (such as salmon and sardines), and fortified foods such as cereal and orange juice.
Calcium Supplements
If you are unable to get enough calcium through your diet alone, your healthcare provider may recommend a calcium supplement. Calcium supplements come in many forms, such as tablets, capsules, and chewable gummies.
It is important to choose a calcium supplement that is easily absorbed by the body. Calcium carbonate and calcium citrate are two common forms of calcium supplements, but calcium citrate is generally considered to be more easily absorbed.
Conclusion
Calcium is an essential nutrient that is important for many bodily functions. In addition to its benefits in building and maintaining strong bones, calcium may also play a role in reducing the risk of certain types of cancer.
While more research is needed to fully understand the connection between calcium and cancer risk, it is clear that adequate calcium intake is important for overall health.
