In 2025, the journal Nutrients released the findings of a pilot study regarding the impact of consistent consumption of Greek yogurt on the wellness of individuals over 55. Main focus was placed on its effect on biochemical markers of bone resorption and inflammation, taking into account participants’ fitness levels.
Forty-eight people took part in the trial, split into two cohorts: one group performed moderate physical exercises, while the other maintained a sedentary lifestyle. Over eight weeks, all subjects ate two servings of Greek yogurt daily (175 grams each). Blood tests were also conducted, and body composition parameters were assessed.
The outcomes revealed variances in the effects from yogurt intake. In the active participants, the serum level of the bone resorption marker CTX-I increased, suggesting an activation of bone tissue renewal processes. In the inactive participants, conversely, a significant drop in interleukin-6—a key biomarker of chronic inflammation—was observed. Meanwhile, alterations in the percentage of fat and muscle mass in both groups were slight.
The study authors acknowledge the preliminary nature of the findings due to the small sample size and brief monitoring duration. Nevertheless, the data suggests the capacity of combining specific food items with physical exertion to enhance physiological processes in older adults. This could form the basis for creating tailored dietary advice to bolster health in advanced age.
