Vitamin D and Calcium: Risks and Benefits
A new study highlights the importance of getting enough vitamin D and calcium for preventing cancers
Dietician and cancer prevention expert reveals risks and benefits
According to a new study published in the Annals of Internal Medicine, getting adequate amounts of vitamin D and calcium may significantly reduce the risk of developing deadly diseases, including certain types of cancers. Cynthia Thomson, a registered dietician and cancer researcher at the University of Arizona, emphasizes the importance of a balanced diet and supplements for overall health.
Reduced cancer deaths, but potential risks
The study followed more than 36,280 postmenopausal women over a period of seven years. Those who took vitamin D and calcium supplements experienced a 7% reduction in cancer-related deaths. The most significant reductions were observed in invasive breast cancer (19%) and colorectal cancer (31%). However, there was a modest 6% increased risk of developing cardiovascular diseases among supplement-takers, with potential calcification of coronary arteries contributing to the risk.
These findings highlight the importance of personalized medicine and considering individual profiles when deciding whether to incorporate supplements into daily routines. Medical professionals, including cardiologists and oncologists, should carefully assess the benefits and risks for each patient.
Factors to consider when supplementing
Use blood test results to determine your supplement regimen
When considering supplements, individuals should evaluate blood test results. Vitamin D deficiency, for example, can be addressed by incorporating 400 IU per day to achieve normal levels. This monitoring ensures effectiveness and tailors the supplementation to each individual’s needs.
Factors such as diet and medical history
An individual’s diet, particularly regarding calcium sources, should be considered when deciding to supplement. Some individuals, such as vegans or those with low consumption of calcium-rich foods, may need calcium supplementation. Additionally, concerns related to medical history, such as a personal or family history of kidney stones, may influence the decision to supplement.
Supplements are not a substitute for a healthy diet
Cynthia Thomson and other leading researchers emphasize that supplements should be used to complement and address dietary inadequacies, not as a replacement for a healthy and diverse diet. Following a plant-rich diet, including fruits, vegetables, whole grains, and nuts, significantly impacts and reduces the risk of developing chronic diseases like cancer. Individuals should prioritize dietary improvements before considering supplementation.
While supplements can have marginal and slow effects on an individual’s health, they are not a magic solution. Each patient’s response to supplements may vary, and the overall health and individual circumstances need to be assessed for a holistic approach to medicine.
Remember, a balanced diet and knowledge of individual health profiles should guide decisions regarding supplementation. By considering these personalized factors, individuals can make informed choices.
