Three claims about your heart for a Thursday check

Your dentist may have mentioned this in passing without connecting the dots for you. Gum health and heart health turn out to be more related than most conversations let on.

TODAY'S TOPIC: Heart and Cardiovascular Health

"A ratio of triglycerides to HDL cholesterol predicts cardiovascular risk better than total cholesterol alone."

Total cholesterol has dominated the conversation for decades as the headline number. A different ratio has quietly outperformed it in research.

The triglyceride to HDL ratio has been shown in multiple studies to correlate more strongly with insulin resistance and small, dense LDL particles, both significant drivers of cardiovascular risk, than total cholesterol does on its own. A high ratio can signal elevated risk even when total cholesterol looks unremarkable on a standard panel.

The headline number on your lab report is not always the most informative one on the page.

Where the evidence splits:

You can drink water the “wrong way”…

…and increase your risk of heart attack by 42%.

I know that sounds crazy.

But it’s true…and it’s happening to millions of Americans right now.

See why this affects you, even if you drink “filtered” water:

Here’s the scary part:

Even though water should be good for your heart…

Most tap water today is loaded with invisible toxins, like PFAS, arsenic, and chlorine.

These chemicals trigger free radical damage inside your body…

That’s how people with “great health” still drop dead from sudden heart attacks.

If you drink water, you need to see this

"Chronic gum disease is linked to an increased risk of heart disease."

Gum health and heart health get treated as entirely separate conversations, one for the dentist and one for the cardiologist. Research increasingly connects the two.

Chronic inflammation from periodontal disease appears to contribute to the same inflammatory processes involved in artery plaque buildup, and several large observational studies have found people with gum disease have a meaningfully higher risk of cardiovascular events. Researchers have not fully settled whether the relationship is directly causal or reflects shared risk factors, but the association itself is well established.

Your gums are not a separate system from the rest of your cardiovascular health.

The research:

"Getting an annual flu vaccine measurably reduces the risk of a heart attack in the following months."

The flu shot gets framed purely as respiratory protection, disconnected from anything cardiovascular. The research says otherwise.

Flu infection triggers a significant inflammatory response that can destabilize existing arterial plaque, and multiple studies, including randomized trials, have found flu vaccination associated with a meaningfully reduced risk of heart attack and cardiovascular death in the months following vaccination, particularly among people with existing heart disease.

A yearly flu shot is doing more for your heart than the marketing around it usually mentions.

What the research actually found:

Your heart is more connected to the rest of your body than the specialist system usually implies. Worth tracking the connections nobody draws for you.
