What beets, bacteria and chewing gum have to do with your blood pressure

Beets have earned their reputation as one of the best foods for healthy blood pressure and circulation.

But here’s something most people don’t realize…

The real magic doesn’t begin in your stomach.

It begins in your mouth.

Beets are naturally rich in dietary nitrates — plant compounds your body can use to produce nitric oxide (NO), one of the most important molecules for healthy circulation.

NO signals blood vessels to relax and expand, allowing blood to flow more freely. That’s why it’s closely tied to healthy blood pressure, oxygen delivery, stamina and artery flexibility.

But nitrates from beets don’t become NO automatically.

First, bacteria in your mouth help convert those nitrates into nitrites. Then those nitrites continue down the pathway that helps your body generate NO.

In other words, your mouth isn’t just where you taste your food. It’s where valuable circulation support gets switched on.

And research has found yet another way the things we put in our mouths impact that switch…

A surprising finding about beets, gum and blood pressure

Researchers at King’s College London recently explored whether saliva acidity could influence how well the body converts dietary nitrates into nitrites.

Healthy volunteers drank a shot of beetroot juice, then chewed either sugar-containing gum or sugar-free gum for several hours. Researchers measured saliva, blood and blood pressure throughout.

The results were surprising.

Compared with sugar-free gum, the sugar-containing gum lowered mouth pH, making saliva more acidic. That shift was linked to higher nitrite production — both in the mouth and throughout the body.

Participants chewing sugary gum had 45% more nitrite in the mouth and 25% more circulating in the body. Their blood pressure also dropped slightly more — by nearly 3/2 mmHg.

But this is not a recommendation to chew sugary gum.

The real takeaway is more useful…

Your mouth environment may influence how much nitric oxide support you get from nitrate-rich foods like beets. So where do you go from here?

Supporting your pH balance

We’ve known the oral microbiome — the community of bacteria living in your mouth — helps convert dietary nitrates into nitrites.

This new study adds another layer: saliva pH appears to play role in nitrate-to-nitrite conversion after consuming beetroot.

That matters because pH is all about balance.

Your mouth is not a static environment. Food, drink, saliva and bacteria all shift its pH throughout the day. And those shifts influence which bacteria thrive — including the beneficial bacteria that help activate the nitric oxide pathway.

It’s a two-way relationship: mouth bacteria influence acidity, and acidity influences the bacteria that live there.

So what can you do to support mouth pH without resorting to sugary gum?

Start with the same foods that support nitric oxide: beets and dark leafy greens.

These nitrate-rich foods help feed the NO pathway while supporting the pH balance the body depends on for healthy function. The trick is pairing that with oral hygiene habits that don’t sabotage the mouth’s microbiome.

For instance, overusing antiseptic mouthwash can be a problem…

While mouthwash can reduce bacteria linked to bad breath and tooth decay, it can also wipe out beneficial nitrate-converting bacteria. That can interfere with the NO pathway, which is meant to support blood pressure, blood flow and arterial health.

Beets are still the star of the show

Even with this new insight, beets remain one of the most practical ways to support nitric oxide production.

Beetroot is rich in dietary nitrates — the raw materials your body uses to produce nitric oxide through the nitrate-nitrite pathway.

When nitric oxide levels are supported, blood vessels can relax and widen more easily. That helps improve circulation, oxygen delivery and overall vascular function.

Unfortunately, nitric oxide production tends to decline with age. As levels drop, blood vessels may become less flexible, circulation less efficient and blood pressure harder to manage.

That’s why nitrate-rich foods are crucial in a circulation-supporting diet — and so is protecting your mouth’s pH.

Get the most from the nitric oxide pathway

This study doesn’t mean you need to change everything about how you consume beets. But it does highlight a few practical ways to support the pathway that turns beet nitrates into nitric oxide.

First, protect your oral bacteria — so you don’t sabotage your efforts to support the NO pathway. Overusing strong antiseptic mouthwash may interfere with the beneficial bacteria that help convert nitrates into nitrites.

Second, be consistent. Occasional beet intake won’t provide the same support as regularly supplying your body with nitrate-rich foods. If you find preparing fresh beets cumbersome, consider using beet powder.

Third, focus on whole-food strategies. Eat more greens and nitrate-rich vegetables that support pH balance and feed the NO pathway. If you want something naturally sweet after a nitrate-rich meal, fruit is a smarter choice than sugary gum because it works with the body’s need for balance instead of against it.

The bottom line?

Supporting that pathway — from your mouth to your blood vessels — may be one of the simplest ways to support circulation, blood pressure and overall health.
