What are nitrates and nitrites, and how do they differ?
Nitrates and nitrites are naturally occurring compounds found in various foods, particularly in vegetables. Nitrates are converted into nitrites in the body, which then combine with other compounds to form nitric oxide. Nitric oxide plays a crucial role in maintaining healthy blood flow, blood pressure, and overall cardiovascular health.
While nitrates and nitrites are often associated with processed meats, they can also be found in high amounts in leafy green vegetables, such as spinach, kale, and arugula. In fact, these vegetables are some of the richest sources of dietary nitrates. By incorporating more nitrate-rich foods into your diet, you can reap the benefits of improved cardiovascular health and reduced inflammation.
What are the health benefits of consuming nitrate-rich foods?
Consuming nitrate-rich foods has been linked to several health benefits, including improved cardiovascular health, reduced blood pressure, and enhanced exercise performance.
