People with diabetes have a bigger risk of having high blood pressure, which can cause heart disease. Too much salt can make your blood pressure high, and most people get way more salt than they need. To cut down on salt, eat fewer canned and processed foods. Use herbs and spices to flavor your food. If you want a snack, choose a piece of fruit or some vegetables instead of salty chips or pretzels. Limit your salt intake to 2,300 mg a day at most. That's less than 1 teaspoon, but salt adds up quickly, even if you don't sprinkle it on your meal.
