摘要：Because the world’s population is deficient in dietary calcium, it is important to search for new sources of this essential mineral for the bones and the entire body. One of the innovative foods that could act as such a source is pumpkin enriched with calcium lactate by means of osmotic dehydration. Providing the body with easily absorbable calcium may have beneficial effects on the reconstruction of bone tissue. Postmenopausal osteoporosis is associated with body weight and fat mass gain, and the aim of the present study was to evaluate the effect of consuming enriched pumpkin on the levels of adipokines and cytokines produced by the adipose tissue. This study was conducted on 12-month-old female Wistar rats that received nutritional intervention for 12 weeks. After termination of the rats, the levels of leptin, adiponectin, interleukin 31 and interleukin 33 in serum and adipose tissue were determined, and the femurs were examined histopathologically. It was demonstrated that calcium-enriched pumpkin reduced bone marrow femoral adipocytes and also markedly decreased serum leptin levels in groups of rats after ovariectomy, which was associated with a decrease of fat content. Additionally, it seems that calcium-enriched pumpkin may reduce body weight gain often observed after menopause.
