Nitric oxide is a crucial part of our body's natural processes, but its production is dependent on factors like nitrate from our diet, specific oral bacteria, and stomach acid. When we consume nitrate-containing foods, like spinach, our salivary glands start producing nitric oxide for several hours, benefiting our health in various ways. It kills harmful bacteria, boosts blood flow, enhances nutrient absorption, and prevents ulcers. However, the use of stomach acid-reducing medications disrupts nitric oxide production and increases the risk of heart attack and stroke. It's vital to maintain a balanced diet and healthy gut bacteria to support this vital process.
