Consuming a diet high in plant foods containing the amino acid arginine is beneficial primarily because arginine serves as a precursor to nitric oxide in the body. Nitric oxide is a vital molecule that plays a key role in vascular health. It helps to relax and dilate blood vessels, which improves overall blood circulation. Enhanced blood flow can have various positive effects on cardiovascular health, including improved oxygen and nutrient delivery to tissues, better regulation of blood pressure, and increased exercise performance.

While protein, calcium, and carbohydrates are essential macronutrients and serve important functions in the body, the specific connection of arginine to nitric oxide production sets it apart in this context. Therefore, the emphasis on the role of arginine in supporting improved blood circulation through nitric oxide production underscores why this answer is particularly relevant when discussing the benefits of a diet rich in plant-based foods containing this amino acid.
