Dairy products are associated with strengthening bones and reducing fracture risk. However, a new study published in the journal Frontiers in Nutrition has shown that no direct link has yet been found between yogurt consumption and bone strength.
Yogurt is produced by fermenting milk with two types of bacteria — Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. Thanks to them, the composition contains more ionized minerals than regular milk.
As a result, yogurt is rich in:
- vitamins B and K;
- calcium;
- phosphorus;
- magnesium;
- zinc;
- selenium;
- high-quality protein.
These micro- and macroelements strengthen bone tissue and promote the rapid recovery of muscle tissue, but their benefits are still insufficient to claim full protection against osteoporosis.
What Researchers Found
Scientists analyzed 12 observational studies involving adults — both healthy and those with osteoporosis. The indicators assessed included bone mineral density, fracture risk, and other parameters.
Ultimately, only 2 studies showed a slight positive effect of yogurt on bone density, but none confirmed a reduction in fracture risk. No reliable correlation was found between the amount of yogurt consumed and bone strength either.
Experts note that most studies did not take into account important factors such as the baseline levels of vitamin D and calcium in participants, the composition and quality of yogurt (fat content, presence of probiotics, vitamin fortification).
Despite the questionable effect on bones, yogurt remains a valuable product. According to the Journal of Food Science, it strengthens gut microbiota, supports immunity, and improves lactose absorption.
