The Claim

In middle-aged and older adults with overweight or obesity, consumption of nitrate-free red beetroot juice has no effect on vascular endothelial function or postprandial cardiometabolic stress.

In plain English

For middle-aged and older adults with overweight or obesity, drinking red beetroot juice without nitrates does not improve blood vessel function or reduce metabolic stress after meals.

See the scientific wording

In middle-aged and older adults with overweight or obesity, nitrate-free red beetroot juice does not improve vascular endothelial function or reduce postprandial cardiometabolic stress, indicating that non-nitrate compounds in beetroot juice do not exert significant acute or chronic effects on these outcomes.

Why this might work

When nitrate is consumed, bacteria in the mouth convert it to nitrite, which then turns into nitric oxide in the blood. This nitric oxide relaxes blood vessels and improves blood flow. Without nitrate, this process does not happen, and the other compounds in beetroot juice do not trigger the same effects on blood vessels or metabolism after eating.

  1. Study: Impact of Red Beetroot Juice on Vascular Endothelial Function and Cardiometabolic Responses to a High-Fat Meal in Middle-Aged/Older Adults with Overweight and Obesity: A Randomized, Double-Blind, Placebo-Controlled, Crossover Trial

    Scientists tested beetroot juice without nitrate in older, overweight adults and found it didn't help their blood vessels or metabolism after a fatty meal. This means the other stuff in beetroot juice (not nitrate) doesn't seem to make a difference for these health outcomes.
