The Salt Story: How Much is Too Much for Your Heart?

Updated: Aug 20, 2023

Salt, or sodium chloride, helps maintain fluid balance and is essential for nerve and muscle function. However, an excessive intake can lead to high blood pressure, a significant risk factor for heart disease and stroke. The American Heart Association recommends limiting sodium intake to 1,500 mg per day, yet the average American consumes over 3,400 mg daily!

So, where does all this salt come from? Most of it sneaks into our diets through processed foods and restaurant meals, not just from the salt shaker on our table. Understanding this is the first step towards reducing your salt intake.

 

Reading food labels is an essential habit to cultivate. Look for the sodium content listed under ‘Nutrition Facts’. Keep in mind that ‘sodium-free’ or ‘salt-free’ means less than 5 mg per serving, while ‘very low sodium’ labels imply less than 35 mg per serving. Terms like ‘reduced’ or ‘less sodium’ mean the product has at least 25% less sodium than the regular version. Opt for fresh fruits and vegetables, which are naturally low in sodium. If buying canned or frozen versions, look for ‘no salt added’ or ‘low sodium’ labels. Choose fresh meats over processed ones, as the latter often contain high levels of salt. Experiment with other seasonings to enhance your food’s flavor. Spices, herbs, vinegar, and citrus can make dishes delicious without the need for extra salt. Remember, cutting down on salt doesn’t mean bland food or a complicated diet—it’s about making smart, informed choices. Over time, your taste buds will adjust, and you might find yourself enjoying the natural flavors of food more.

 

While salt is a necessary part of our diet, excessive amounts can impact our heart health. By being mindful of our intake, we can pave the way for a healthier heart and a healthier life. And as always, feel free to discuss any dietary concerns during your next visit. Balancing your salt intake might seem like a daunting task at first, but with these simple strategies, it’s easier than you think! Your heart will thank you for it.
