Research Finds One Cup Of This Nitrate-Rich Veggie May Reduce Heart Disease Risk

A team of researchers from Edith Cowan University, the Danish Cancer Society, and the University of Western Australia wanted to look at how leafy greens affected blood pressure and heart disease risk. Their focus was specifically on nitrate-rich vegetables, so think kale, collards, spinach, along with beets and garlic.

As cardiologist Alejandro Junger, M.D., previously explained to mbg, "Nitrate-containing nutrients are essential precursors of nitric oxide, which helps to relax the arterial walls and regulate the blood-clotting cascade2."

The team discovered that those who ate the most nitrate-rich vegetables, like leafy greens, not only had lower blood pressure but also a 12 to 26% lower risk of heart disease. But as it turns out, just 1 cup a day seemed to do the trick.

As lead researcher Catherine Bondonno, Ph.D., explains in a news release: "Our results have shown that by simply eating one cup of raw (or half a cup of cooked) nitrate-rich vegetables each day, people may be able to significantly reduce their risk of cardiovascular disease."

She adds that the greatest reduction in risk was found for peripheral artery disease, which narrows the blood vessels in the legs. "However," she says, "we also found people had a lower risk of heart attacks, strokes and heart failure."

Leafy greens and other nitrate-rich vegetables are important for heart health, as well as muscle function. And according to this recent research, you may only need a cup a day to reap the benefits.
