Which sulfur compounds present in onions are believed to help reduce high blood pressure, contributing to overall cardiovascular wellness?
Answer
Thiosulfinates
The cardiovascular benefits derived from onion consumption are partly attributed to the unique array of sulfur compounds they contain. Specifically, thiosulfinates are cited as sulfur compounds believed to exert a positive effect on blood pressure regulation, potentially helping to reduce elevated levels. This mechanism is one component of how onions contribute to heart health, alongside the effects of quercetin on blood vessel flexibility. Maintaining healthy blood pressure is a critical risk factor management goal in preventing heart disease, making the presence of thiosulfinates an important aspect of the onion's protective profile.
