The most beneficial aspect of consuming a diet high in plant foods that contain arginine is that it significantly contributes to the production of nitric oxide in the body. Nitric oxide plays a vital role in improving blood circulation and promoting cardiovascular health. While protein is essential for muscle growth, arginine itself is particularly noted for its function in enhancing endothelial function and the vasodilation process, leading to better circulation.

Therefore, focusing on the benefits of arginine leads to the conclusion that it directly supports the production of nitric oxide, which is crucial for optimizing blood flow and overall cardiovascular function. This connection is what makes the option regarding nitric oxide the most relevant in the context of arginine-rich plant foods.
