Howard G. Smith MD, AM on Instagram: "Snacks May Save Couch Potatoes And Desk Hermits Excessive sitting can be lethal. It reduces healthy blood vessel widening, so-called flow-mediated vascular dilatation. Even a 1% decrease in this vessel stretching is associated with a 13% increased risk for heart disease and stroke. University of Birmingham rehabilitation researchers now publish a study in The Journal of Physiology demonstrating that flavanol-rich foods can prevent the temporary decline in blood vessel widening that follows an extended periods of sitting. Forty healthy young men consumed either a high-flavanol, 695 mg., cocoa drink or a low-flavanol version prior to sitting for 2 hours. The results? Those consuming the high-flav drink show no sitting-induced arterial widening decline. Those receiving the low-flav drink experienced that decline as well as blood pressure spikes and reduced leg muscle oxygenation. Fitness offered no protection. Besides cocoa, other flavonol-rich foods are black and green tea, apples, plums, berries, and nuts. To keep your legs healthy, take a short stroll for 5-10 minutes each hour. https://www.sciencedaily.com/releases/2025/11/251124094325.htm https://physoc.onlinelibrary.wiley.com/doi/10.1113/JP289038 #sitting #flavanol #legs #bloodvessels #dilatation #heartdisease #stroke"

A study by University of Birmingham researchers found that flavonol-rich foods can prevent blood vessel decline caused by prolonged sitting. Participants who consumed high-flavonol cocoa drinks showed no decline in arterial widening, while those who consumed low-flavonol drinks experienced blood pressure spikes and reduced leg muscle oxygenation. Incorporating healthy snacks into your daily routine can make a significant difference in your overall health and well-being.
