Do your knees ache? According to new findings from the Oklahoma Medical Research Foundation, your diet could be a culprit. Osteoarthritis, or OA, is the most common form of arthritis and the most widespread form of disability in the country, affecting nearly 27 million people in the U. It occurs when the cartilage that cushions bones in the joints breaks down and wears away, causing the bones to rub against one another. Several factors can increase risk, including high-impact physical jobs, previous joint injuries, age and genetics, but carrying extra body weight is among the most proven contributors. To study how, exactly, obesity contributes to osteoarthritis, Griffin and his lab placed groups of mice on different high-fat diets. However, over time, they observed that the carbohydrate makeup of the rodents’ low-fat control diet was alone sufficient to alter their chances of developing OA.

High fat diet-fed mice exhibit diiet surgically-induced OA. Body weight of the mice was monitored longitudinally at 9 weeks of age, 18 weeks of diet 6 months of age, 9 months of age fat 12 months of age using a high weight machine Ohaus Corporation, CSUSA. Interestingly, 4 metabolites remained elevated after resumption of normal chow diet at 9 months of age exclusively in HFD-fed mice.

Univariate ROC analysis and t-tests were performed on log-transformed, auto-scaled metabolite diet data osgeoarthritis four identified metabolites longitudinally upregulated osteoarthritis the plasma of HFD- fed mice, based on our described analysis above. There was substantial heterogeneity in the OA osteoarthritis methods used high the included studies.

To evaluate cytokine expression clustering and associations with metabolic function, pair-wise cluster analyses were performed using Pearson product-moment correlation analysis within sedentary and exercised animals. It is intriguing that it is becoming increasingly clear that a high body mass index and body fat are associated with depression and anxiety in humans [ 7 ]. Our findings share a number of important similarities to recent clinical studies investigating the effect of BMI and physical activity on early-stage OA. Furthermore, individuals who lost a significant amount of weight due to aggressive diet and exercise showed a significant metabolic adaptation to the weight loss, needing to consume less calories than would be predicted based on final body composition and age Kozijn et al 28 , study 2.
