Interferes with vitamin D metabolism, which is essential for calcium absorption
Reduces activity of bone-building cells (osteoblasts)
Heavy drinking increases risk of fractures due to poor balance and falls
Important point:
Moderate intake may have less impact, but chronic or heavy drinking is strongly linked to bone loss (osteoporosis risk).
3. Excessive caffeine drinks (coffee, strong tea, energy drinks)
Caffeine isn’t “bad” in moderation, but high intake matters.
Why they’re harmful:
Increases calcium excretion through urine
May slightly reduce calcium absorption
Energy drinks often combine caffeine + sugar + acids, increasing the risk
Key detail:
The effect becomes more noticeable when calcium intake is already low.
