Health experts generally point to five categories of drinks that may be the most harmful to bone health when consumed frequently, especially if they replace calcium- and vitamin D-rich beverages in the diet.
1. Sugary Cola Soft Drinks
Cola beverages are the most consistently linked to lower bone mineral density. Researchers believe the combination of phosphoric acid, added sugar, and often caffeine may contribute to poorer bone health. Studies have found associations between higher cola intake and lower hip bone density, particularly in women. (Harvard Health)
2. Excessive Alcohol
Heavy alcohol consumption can interfere with calcium absorption, disrupt hormones involved in bone maintenance, and increase fracture risk over time. Experts recommend moderation rather than complete avoidance for most adults. (Cleveland Clinic)
3. Energy Drinks
Many energy drinks contain large amounts of caffeine and sugar. High caffeine intake may increase calcium loss in urine and can negatively affect bone density if calcium intake is inadequate. (Cleveland Clinic)
4. High-Sugar Drinks (Sweetened Teas, Fruit Drinks, Sodas)
Sugar-sweetened beverages have been associated with lower bone mineral density and higher fracture risk. Excess sugar may increase calcium loss and often displaces healthier beverage choices such as milk or fortified drinks. (GoodRx)
5. Excessive Coffee and Other Highly Caffeinated Drinks
Moderate coffee consumption is generally considered safe, but very high caffeine intake may slightly reduce calcium absorption and contribute to bone loss, especially in people who consume little calcium. Recent research suggests moderate coffee intake has little effect, while very high intake may be associated with lower bone density. (Cleveland Clinic)
What isn’t as harmful as many people think?
Plain sparkling water and other non-cola carbonated waters do not appear to harm bones. Research suggests that the problem is not the carbonation itself but ingredients such as phosphoric acid, sugar, and excessive caffeine found in some beverages. (Harvard Health)
Better Choices for Bone Health
- Milk and fortified plant milks
- Plain water
- Calcium-fortified beverages
- Moderate amounts of tea (some studies suggest it may even have modest bone benefits) (Verywell Health)
The biggest factors for strong bones remain adequate calcium and vitamin D intake, regular weight-bearing exercise, not smoking, and limiting heavy alcohol and excessive sugary soda consumption. (Cleveland Clinic)
