Eight cups of coffee a day promotes calcium deficiency, according to the study

Australian researchers conducted a study for the first time to determine how large amounts of coffee affect bone health. There is obviously an increased excretion of essential calcium nutrients – this increases the risk of osteoporosis in the long run.

Caffeine is the most popular “recreation drug” in the world. Finally, most adults consume at least one caffeinated beverage a day. However, anyone who ingests more than 800 milligrams – that’s about eight cups of coffee – risks a massive calcium deficiency. According to a recent Australian study, this increases the risk of osteoporosis in the long run.

77% calcium loss in the high caffeine group

Many clinical studies on caffeine and its effects on health have focused on the question of how a stimulant substance affects the heart, brain or circulation. Researchers from the University of South Australia have now, for the first time as a partial study, examined the effects that high levels of caffeine can have on the kidneys and calcium balance. Therefore, in a double-blind clinical study, healthy adults chewed caffeine or a placebo chewing gum for five minutes at two-hour intervals (total caffeine 800 milligrams) over a six-hour treatment period.

In the group of caffeine, an increased loss of calcium of 77 percent in the urine was subsequently determined. It is said that this could negatively affect the bones in the long run. The study was published in the British Journal of Clinical Pharmacology.1 “The average daily intake of caffeine is about 200 milligrams – about two cups of coffee. Drinking eight cups of coffee can seem like a lot, but there are groups that fall into this category, “explains the author of the study, Dr. Stephanie Reuter about this in a university announcement. 2

Researcher: Excessive coffee consumption is a risk factor for osteoporosis

Calcium is an essential and quantitatively most important nutrient in the body, which ensures strong bones and healthy teeth. Children, pregnant women and non-menopausal women in particular need to take care of adequate supply. Calcium deficiency can lead to osteoporosis (bone loss). In those affected, the bone substance gradually breaks down. This makes them more unstable and fragile. In Germany, about 800,000 people develop a painful disease every year.3 For researcher Stephanie Reuter, moderate coffee consumption could avoid at least one risk factor for calcium deficiency: “Caffeine in moderation certainly has its benefits. But it’s important to understand how excessive consumption can increase the risk of preventable diseases, such as osteoporosis. “

Calcium loss also applies to energy drinks

Researchers also note with concern that many professional groups use high doses of caffeine to increase their performance. This includes shift workers, professional athletes or members of the military. The huge consumption of energy drinks among teenagers is considered especially problematic. “Adolescents are especially at risk because their bones continue to grow.

Whether through coffee or energy drinks – the fact that too much caffeine leads to calcium loss, according to the study, should become an urgent concern of the population. The next step is to investigate how different amounts of caffeine affect bone health in the short and long term.
