Last Updated: 2026/07/13, The claim that coffee causes calcium loss was made before 1990, because research models ignored the fact that middle-aged women were already deficient in calcium and needed calcium supplements, so they came to the wrong conclusion that coffee causes calcium loss. After 1990, statistical models were designed to exclude the middle.

The argument about calcium loss caused by drinking coffee was before 1990, because the research model ignored the fact that middle-aged women were deficient in calcium and needed calcium supplements, so they came to the wrong conclusion that drinking coffee led to calcium loss.

After 1990, when designing statistical models, people excluded the factor of calcium deficiency in middle-aged women, replaced the direct intake of "caffeine" with coffee, and expanded the number of subjects (statistical population) from thousands to tens of thousands, or even tens of thousands.

The new conclusion negates the previous conclusion, but some people still think that eating too much coffee will lead to osteoporosis, but if you drink milk coffee, milk gives you far more calcium than your so-called calcium loss.
