Exercise protects the hypothalamus morphology from the deleterious effects of high sucrose diet consumption

A growing body of evidence suggests that elevated sucrose intake may contribute to the development of neurological disorders. Recognizing that regular exercise has the potential to reduce the occurrence of neuromuscular disorders, the present research investigated the impact of exercise on the redox status of the hypothalamus in mitigating the adverse effects associated with high sucrose intake. Forty Wistar albino rats were subjected to a high sucrose diet, with some groups engaging in exercise for a duration of 3 months. The exercise regimen was found to sustain the redox balance in the hypothalamus. In summary, the consumption of a high sucrose diet resulted in the disturbance of the histological morphology of the hypothalamus, accompanied by an increased percentage of caspase-3 positive cells. Additionally, the high sucrose diet disrupted the oxidant/antioxidant ratio in favor of oxidants, leading to elevated levels of AOPPs and AGEP. Conversely, exercise was effective in restoring most of these values to levels approximating the control group, indicating a potential protective effect of regular exercise against the detrimental impacts of high sucrose dietary consumption on the hypothalamus.
