If the just the mention of potato chips makes your mouth water, new research says you might be able to blame your salt addiction on your genes.

It's true--some of us actually carry a genetically driven salt tooth.

The craving for salt could affect how much you shake on your food, which can also have an effect on the health of your heart.

This gene was discovered by researchers at the University of Kentucky who looked at those who had two risk factors for heart disease. In the process, researchers discovered all of them had a common gene called TAS2R38, which caused them to crave salt.

Here's how to tell if you might have that salty gene:

If you don't like things that taste bitter, you most likely have the gene. For example, your dislike of bitterness may have you salting vegetables, like broccoli and asparagus, that have a bit of a bitter taste.

It's important to remember that increasing your salt intake also increases your chances of developing high blood pressure, which in turn can increase your risk of heart attack and stroke. The reason why is due to high levels of sodium in your blood reducing your kidneys ability to remove the water from your body.

Just as a reminder, the daily allowance for salt is a teaspoon a day and that's not just from the salt shaker but from all the food you eat.
