While supplements can support bone health, lifestyle choices play a major role in the development of osteoporosis.
A study published in the American Journal of Clinical Nutrition (2006;84[4]:936–942) found that daily cola consumption was associated with lower bone mineral density. Women who drank cola daily had 3.7–5% lower bone density compared with women who consumed cola less than once per month.
Lifestyle patterns were also examined in a study of 632 Japanese women over age 60, published in the Journal of Orthopedic Science (2007;12[4]:317–320). Regular physical activity and green tea consumption were associated with a lower risk of osteoporosis. Smoking was linked to lower bone density.
Dietary protein patterns appear to matter as well. In the EPIC-Potsdam cohort (8,178 women), reported in the Annals of Nutrition and Metabolism (2005;49[5]:312–318), higher animal protein intake was associated with lower bone density, while higher vegetable protein intake was associated with better bone density. Calcium intake supported bone density, but its benefit was less pronounced in women consuming high amounts of animal protein.
Bottom line: Bone health is influenced not just by calcium or supplements, but by diet quality, beverage choices, physical activity, and smoking status—reinforcing the importance of lifestyle-based prevention.
