Association Between Adherence to the Mediterranean Diet and Metabolic Syndrome and Its Components Among Polish Postmenopausal Women: A Cross-Sectional Study
Background/Objectives: The decrease in estrogen levels during menopause is associated with an increase in visceral fat accumulation, which can contribute to the development of metabolic syndrome (MetS). While some studies have suggested a link between the Mediterranean diet (MedDiet) and the reduced incidence of MetS and its components in the general population, these findings have not been confirmed among postmenopausal women. Therefore, this study investigated the association between the adherence to the MedDiet and the odds of having MetS, and established the food groups responsible for this effect in postmenopausal women. Methods: This cross-sectional study involved 312 postmenopausal women who underwent anthropometric measurements and blood parameter assessment. Adherence to the MedDiet was assessed using the Alternate Mediterranean Diet score (the aMED score), and MetS was defined based on the updated 2022 criteria. Results: After adjusting for potential confounders, adherence to the MedDiet was inversely associated with central obesity and hypertension. For each one-point increase in the aMED score (indicating a better adherence to the MedDet), the odds of central obesity and hypertension were significantly reduced by 33% (OR = 0.669, 95% CI: 0.518; 0.866, p = 0.002) and by 18% (OR = 0.817, 95% CI: 0.689; 0.969, p = 0.020), respectively. A greater consumption of nuts and fish was associated with lower odds of central obesity (OR = 0.972, 95% CI: 0.950; 0.995; p = 0.016) and (OR = 0.989, 95%CI: 0.979; 1.000; p = 0.043), respectively, whereas high processed red meat consumption was associated with hypertension (OR = 1.004, 95% CI: 1.000; 1.008, p = 0.048). Conclusions: A greater adherence to the MedDiet was associated with lower odds of central obesity and hypertension among postmenopausal women; however, it did not translate to a reduced likelihood of having MetS. A higher consumption of nuts and fish was associated with lower odds of central obesity, whereas a higher consumption of red, processed meats was associated with higher odds of hypertension. Longitudinal studies are needed to determine the causality of these relationships.

The Role of a High-Fat, High-Fructose Diet on Letrozole-Induced Polycystic Ovarian Syndrome in Prepubertal Mice
This study aims to investigate the effects of a high-fat, high-fructose (HF/HFr) diet on metabolic/endocrine dysregulations associated with letrozole (LET)-induced Polycystic Ovarian Syndrome (PCOS) in prepubertal female mice. Thirty-two prepubertal C57BL/6 mice were randomly divided into four groups of eight and implanted with LET or a placebo, with simultaneous administration of an HF/HFr/standard diet for five weeks. After sacrifice, the liver and blood were collected for selected biochemical analyses. The ovaries were taken for histopathological examination. The LET+HF/HFr group gained significantly more weight than the LET-treated mice. Both the LET+HF/HFr and the placebo-treated mice on the HF/HFr diet developed polycystic ovaries. Moreover the LET+HF/HFr group had significantly elevated testosterone levels, worsened lipid profile and indices of insulin sensitivity. In turn, the HF/HFr diet alone led to similar changes in the LET-treated group, except for the indices of insulin sensitivity. Hepatic steatosis also occurred in both HF/HFr groups. The LET-treated group did not develop endocrine or metabolic abnormalities, but polycystic ovaries were seen. Since the HF/HFr diet can cause substantial metabolic and reproductive dysregulation in both LET-treated and placebo mice, food items rich in simple sugar—particularly fructose—and saturated fat, which have the potential to lead to PCOS progression, should be eliminated from the diet of young females.
