A landmark long-term study of more than 54,000 adults published online June 8, 2026 in a major clinical journal has delivered one of the most compelling pieces of dietary evidence for heart health in recent years — and its implications are particularly significant for New York City, where cardiovascular disease remains the leading cause of death and where millions of residents live in neighborhoods with limited access to fresh produce. The study found that adults who consumed approximately 60 milligrams of nitrate from vegetables each day — the amount found in about one cup of baby spinach, half a cup of cooked beets, or two cups of lettuce — had a 15% lower risk of developing cardiovascular disease compared to those who consumed the least vegetable nitrate.
More specifically, moderate vegetable nitrate intake was associated with 12% lower risk of ischemic heart disease, 15% lower risk of heart failure, 17% lower risk of ischemic stroke, and a remarkable 26% lower risk of peripheral artery disease hospitalization — the condition that causes blocked leg arteries, pain, and in severe cases, amputation. The findings, which followed participants for up to 23 years with 14,088 documented cardiovascular events, represent some of the strongest long-term observational evidence linking a specific dietary pattern to reduced cardiovascular outcomes. Critically, the benefit came from vegetables — not from nitrate supplements or processed meats, which are associated with increased cancer risk.
