Salt leads to high blood pressure:

When there’s extra sodium in your bloodstream, it pulls water into your blood vessels, increasing the total amount (volume) of blood inside them. With more blood flowing through your blood vessels, blood pressure increases. It’s like turning up the water supply to a garden hose — the pressure in the hose increases as more water is blasted through it.
Over time, high blood pressure may overstretch or injure the blood vessel walls and speed the build-up of gunky plaque that can block blood flow. The added pressure tires out the heart by forcing it to work harder to pump blood through the body. And the extra water in your body can lead to bloating and weight gain.
High blood pressure is known as the “silent killer” because its symptoms are not always obvious. It’s one of the major risk factors for heart disease, the No. 1 killer worldwide. Almost no one gets a free pass. Ninety percent of American adults are expected to develop high blood pressure over their lifetimes.
Did you know that sodium can affect your blood pressure even more dramatically if you’re sensitive to salt? Recent science explains that certain factors may influence how your blood pressure changes when you eat salt, such as:
Age
Weight
Race/ethnicity
Gender
Some medical conditions (like diabetes or chronic kidney disease)
Even if you don’t already have high blood pressure, eating less sodium can help blunt the rise in blood pressure that occurs with age. It can also reduce your risk of heart attack, heart failure, stroke, kidney disease, osteoporosis, stomach cancer and even headaches.
