Garlic has around 17mg of sodium for every 100g, which is a fairly significant amount. Just one tablespoon of garlic powder contains 2mg of sodium. Those who are trying to cut down on the amount of sodium they put into their bodies will want to think about limiting the amount of garlic they have, as it is fairly high in sodium.
There are a lot of different healthier alternatives to garlic that do not contain nearly as much sodium and can still be enjoyed. Garlic does have a number of health/nutritional benefits though, such as the ability to lower blood pressure and cholesterol levels.
