How is high salt intake bad for cardiovascular health?


I know high sodium diets contribute to heart disease, and people recovering from heart attacks are advised to go on low sodium diets; but how does NaCl actually contribute to the blocking of arteries?

Salt increases the amount of blood in your arteries making it harder for the heart to pump loos through the body.

While it doesn’t directly influence the “blocking” of arteries, with thicker blood comes higher blood pressure, which can lead to CHF.

In chemistry, there is something called the “osmotic force.” It says that, whenever there is something dissolved in water, water molecules will move to make the concentration of that dissolved substance equal throughout. The important idea is that the water molecules move, not the substance that dissolved. Water moves.

When you take in a lot of sodium, it goes from your mouth to your stomach to (eventually) your blood. When your blood is more salty than the tissue around it, the tissue pours its water into your blood. Because your veins and arteries are the same size as before your body threw all this water in them, the extra water increases the amount of liquid your body is pushing around. This increases the pressure… same pipes, more liquid, more pressure. With extra water, you need extra oomph to move it through the body, and it hits the pipes harder than it used to.

This is the pressure required to keep your blood flowing. This is blood pressure, and your heart must provide it or you die.

One can vitiate this process by drinking enough water with salty foods that cellular water needn’t be used for dilution. In other words, eat snacks + drink water.

Some great answers here but it seems that the most obvious answer is this… what foods does salt best taste great on??? I’ve cream, cereal, a peanut butter and jelly sandwich or on anything deep-fried?
The more salt you consume, the more likely it is going to be salt on top of deep-fried foods which raises your cholesterol levels along with water retention.
