A new study... a strange effect of caffeine on "vitamin D"

New research sheds light on a strange association between caffeine, which is present in many products, especially coffee, and the most popular and very common and necessary nutritional supplement for the human body, "vitamin D".

Beverages that contain large amounts of caffeine are very common in the world, which citizens are accustomed to drinking almost daily, such as coffee, tea, hot chocolate, soft drinks of all kinds, energy drinks and some milk products.

Caffeine's Strange Effect on Vitamin D

Medical researchers in China and Brazil recently carried out a study that will soon be published in the International Journal for Vitamin and Nutrition Research.

The study was based on previous research that identified a negative effect of caffeine on vitamin D.

Previous research indicated that caffeine consumption is associated with a decrease in the formation of "vitamin D" receptors in humans, which has effects related to low levels of this important element.

Scientists tried to confirm the existence of this relationship through new research

Scientists have tried to confirm the results of the old study with new research in which doctors examined nutrition data collected from more than 13,000 participants in the National Health and Nutrition Examination Survey between 2005 and 2006.

After collecting the data, the researchers neutralized all health-related side factors that might affect their findings and focused on the results of clinical tests that provided information about vitamin D and regular caffeine intake.

Results confirm a negative effect of caffeine on vitamin D levels.

The results of a new study, which was published by the American magazine “Eat This, Not That”, warned that if a person includes in his diet foods that contain a lot of caffeine on a daily basis, “caffeine can interfere with the body’s ability to absorb vitamin D.”

The researchers noted that the more individuals drank caffeine, the greater the risk of vitamin D deficiency.

In their study summary, the authors clearly stated: "Higher caffeine intake was associated with vitamin D deficiency in a representative sample of the American population."

The researchers noted that more research is needed to confirm these results, especially since at the present time, "it is not clear what are the criteria that distinguish healthy caffeine levels from those associated with low levels of vitamin D."

But the article noted that the more serious question is;

How caffeine affects vitamin D levels in older individuals The data used in this study were collected from individuals aged 30 to 47 years.
