Excessive coffee intake can increase the risk of osteoporosis
Excessive coffee intake can increase the risk of osteoporosis. Excessive intake can cause calcium loss in the body and increase the risk of osteoporosis
Coffee is the most popular beverage worldwide. 80% of adults drink at least one caffeinated beverage every day. It is estimated that 3 billion cups of coffee are consumed every day in the world.
Because it contains a large amount of caffeine, it is often consumed by people to refresh their minds and improve work efficiency. A number of past studies have shown that drinking coffee on a regular basis can bring many health benefits. However, it is not clear what effect an excessive amount of coffee will have on the body.
Osteoporosis is a chronic disease that causes bone density to decrease, making it easier to fracture. More commonly in women, this happens when bones lose calcium and other minerals faster than the body can replace them.
Recently, researchers from the University of South Australia published a research paper titled: The effect of high-dose, short-term caffeine intake on the renal clearance of calcium, sodium and creatinine in healthy adults in the British Journal of Clinical Pharmacology.
The study found that high-dose caffeine (800mg) intake within six hours doubles the amount of calcium lost in the urine, which may be related to an increased risk of osteoporosis.
Caffeine intake is associated with osteoporosis, which is believed to be due to increased excretion of calcium in the urine leading to increased bone absorption. However, the calcium content in urine may not necessarily reflect the true effect of caffeine on calcium removal. Therefore, this study examined the effect of high-dose, short-term caffeine intake on calcium, sodium, and creatinine clearance in the kidneys of healthy adults.
In a double-blind clinical study, participants chewed caffeine or placebo gum for five minutes (800mg total caffeine) every 2 hours within 6 hours.
When studying the effect of coffee on how the kidneys regulate calcium in the body, researchers found that people who consume a high dose of caffeine (800mg) within six hours will increase the calcium content in urine by 77%, which may affect bones. Potential defects
Caffeine and placebo comparison, A urine output, B calcium renal clearance, C creatinine renal clearance, D sodium renal clearance
In addition, this effect is positively correlated with sodium clearance and urine output, indicating that caffeine may act by inhibiting sodium reabsorption in the proximal tubules.
This study confirms that caffeine does increase renal calcium clearance. Researchers say that the right amount of caffeine certainly has its advantages, but it is important to understand how excessive intake increases the risk of highly preventable diseases such as osteoporosis.
