Too much salt makes your heart and blood vessels work harder as you age
Sodium and blood pressure

Your body is built for very little salt, but most people eat way more. Eating lots of salt over time makes your blood pressure go up as you get older, your heart gets bigger, your arteries get stiffer, and you're more likely to have a stroke. Cutting back a little helps lower your blood pressure and keeps your heart healthier.
Surprising Findings
High salt intake increases left ventricular mass independently of blood pressure rise.
Most assume heart thickening is just a side effect of high BP — but this suggests salt directly harms the heart muscle, even if BP stays normal.
Practical Takeaways
Reduce daily salt intake from 10g to 6g by avoiding processed foods, skipping added salt at the table, and choosing low-sodium versions of sauces and snacks.

Eating more salt won't make your blood pressure stay high if you're otherwise healthy.
Cutting back a little on salt — even if you eat a lot now — can help lower blood pressure and reduce the risk of heart attacks and dying early.
People who eat a lot of salt (6-12 grams a day) tend to develop higher blood pressure as they get older, while those who eat very little salt (less than 3 grams) don’t see the same increase.
Eating too much salt is linked to a thicker heart muscle, more strokes, stiffer blood vessels, and tighter small arteries — all of which can hurt heart health.
