Dietary nitrate enhances exercise performance and preserves endothelial function in patients with peripheral arterial disease and healthy individuals, likely by improving blood flow to hypoxic tissues.

If you have peripheral arterial disease or are an athlete looking to improve performance, incorporating high-nitrate vegetables like beetroot, spinach, or rocket into your diet may help. The benefits come from nitric oxide improving blood flow to working muscles. This effect is seen with both acute doses (a single serving) and chronic daily intake.

Why this rating

Supported by pre-clinical and some human studies, but the paper notes a need for more evidence on hard endpoints and long-term effects.
