If your healthcare provider has put you on a low sodium diet, you likely have many questions and thoughts going through your mind. Low sodium diets, also known as low-salt diets or sodium restricted diets, are among the most common diets prescribed to people by their doctors. Reducing sodium can help address several health issues and may be integral to managing and recovering from certain illnesses.
A low sodium diet is defined as a diet that seeks to limit daily sodium intake in foods, drinks, and medications. If you’ve been put on a low sodium diet or are thinking about reducing your sodium intake as a prevention measure, read on.
This article will look at the most common reasons for low sodium diets, the details on foods to choose and foods to avoid, how to handle eating out at restaurants, and more. A low sodium diet may seem daunting at first, but it is a manageable lifestyle change if you have the tools to understand it and make it work for you.
How does a Low Sodium diet work?
To understand how a low sodium diet works, you first have to know the role sodium plays in your body.
Sodium is a mineral that the human body needs to function correctly. Sodium helps the body perform some essential tasks. Its primary function is to regulate the body’s water and mineral levels. When the water-mineral balance is correct, the body’s systems can work in harmony without glitches. You need sodium to help your brain send messages to your body so that your muscles can function the way they should.
When you have too much sodium, the balance becomes disturbed, and you can have excessive fluid buildup in your body’s tissues. It causes an increase in the amount of blood your body has to pump. High blood pressure, swelling of extremities, and fluid buildup around the heart are all symptoms of excessive sodium.
What are the health benefits of a Low Sodium diet?
A low sodium diet can help reduce blood pressure and limit fluid buildup in the body. Many patients who are placed on a low sodium diet by their doctors see improvement in their condition in about one to two weeks.
The standard American diet is typically quite high in sodium, and people often consume much more sodium than is healthy on a daily basis. Some individuals choose to lower their dietary sodium as a preventive measure to avoid having problems with their health later in life. Making a conscious decision to reduce your dietary sodium and adopt a healthier lifestyle can help keep you healthy.
What are the health risks of a Low Sodium diet?
As mentioned earlier, bodies need sodium to function properly. If your body is deprived of the sodium it needs, you can face inevitable consequences. While high sodium diets can lead to health problems, diets too low in sodium can also have significant risks.
- Studies have shown that low sodium diets can worsen insulin resistance for some people. Insulin resistance means that your body doesn’t respond the way it should to the hormone insulin, which regulates blood sugar.
- Some studies suggest that a low sodium diet can increase LDL cholesterol levels. LDL is what is known as the “bad” cholesterol. It’s unclear why low sodium could cause LDL to go up, and more studies are needed.
- If your sodium levels are extremely low, you can be in danger of serious effects, including seizures and other uncontrollable body movements, headaches, and even coma and death.
It’s good to consult with your doctor before making any significant dietary changes. It would be best if you started a very low sodium diet only under the guidance of a healthcare provider who can weigh the risks against the benefits.
You can choose to reduce your dietary sodium yourself as part of a healthier diet as long as you keep your daily intake within normal healthy levels, around 2300 milligrams per day.
What are the guidelines for a Low Sodium Diet?
If you’re thinking about switching to a Low Sodium Diet, it can be difficult to remember all the things it entails. For that reason, we’ve created a simple guideline based on science to make the process easier for you.
- Eliminate salty foods from your diet and reduce the amount of salt
- Choose low sodium foods
- Read the label first before using salt substitute
- Be creative and season your foods
- Read ingredient labels to identify foods high in sodium
- Eat more home-cooked meals
- Don’t use softened water for cooking and drinking
- Avoid medications which contain sodium
1. Eliminate Sources of Excessive Salt
Sounds like a no-brainer, right? You’ll just stop using table salt! Reducing your use of table salt is definitely an excellent place to start, but it’s nowhere near the whole story. The majority of foods in grocery stores contain some amount of sodium, and when you’re counting grams each day, they can add up quickly!
In addition to eliminating extra table salt from your food, you’ll need to weed out foods that are already high in sodium. The first culprits are what you’d expect – ham, bacon, and other preserved meats, many prepackaged foods, chips, crackers, pickles, and olives. Try to find lower-sodium alternatives and use them sparingly.
You’ll also want to limit dairy products and baked goods, which can contain surprisingly high amounts of sodium. That’s not to say you can’t ever eat these foods; you’ll just want to eat them in moderation. The same is true of soups, dips, and other condiments.
2. Choose low sodium foods
There are foods that are naturally low in sodium. These should be the first choices for those trying to reduce their dietary sodium intake. Some low sodium foods are.
- Fresh vegetables and fruits.
- Plain oatmeal (not the ones in packets).
- Fresh meats and fish.
- Plain unflavored pasta from a box (dried spaghetti, ziti, etc.).
- Dried, unflavored beans and grains.
There’s a long list of low sodium foods. You can also look into healthier versions of your favorite foods, like low sodium cheese. While most hard cheeses are high in salt, many brands of Swiss cheese are low in sodium. There are also low sodium versions of many canned vegetables. Add these items to your shopping list and familiarize yourself with the stores that sell them.
3. Read the label first before using a salt substitute
Many people who go on a low sodium diet miss the taste of salt in their food, at least in the early days of following the diet. Salt brings out the flavor of food, and if you’re used to eating more significant amounts of salt, you may feel like your food is bland without it.
Salt substitutes are popular for those on a low sodium diet because they can enhance the flavor of your food in a similar way to salt. These substitutes can be helpful, but you should be cautious about using them in excess, especially if you have certain conditions.
Some salt substitutes contain high amounts of potassium. Potassium can lower blood pressure, which can be beneficial for those who are on a low sodium diet due to high blood pressure. However, for some individuals, high potassium can cause problems if you have kidney problems, heart disease, diabetes, and other conditions.
You should read the labels when shopping for a salt substitute and make sure it is safe for you to use. Saly substitutes that contain herbs and spices to give food flavor are a good choice if you don’t want to add potassium to your diet.
4. Be creative and season your foods
Going on a low sodium diet can help you get more creative with your cooking. Salt is a simple flavoring that can give some flavor to otherwise plain foods. When you have to lower your salt intake, you may want to experiment with other more complicated flavors.
It’s a good time to try new recipes and figure out what combinations go well together! Try cooking with more herbs and spices, maybe trying some you haven’t experienced before. You can also give your food more pizazz by adding tart flavors like citrus or vinegar.
5. Read ingredient labels to identify foods high in sodium
Food nutrition labels become an essential part of your life when you’re on any special diet. For a low sodium diet, you have to identify how much sodium each food has and “budget” your intake on a daily basis. You may be surprised to find out just how much sodium is in some common foods.
On most standard U.S. nutrition labels, the sodium content is found right in the middle, on the fifth row from the bottom. Sodium is measured in milligrams (mg).
On that same line, you’ll also find the percentage of the RDA (recommended daily allowance) of sodium in one serving of the product. Some food labels show you percentages for one serving AND the entire package, so you can compare.
The RDA for sodium is 2300 mg, so most nutrition label percentages are built on that number. If your doctor-prescribed sodium restricting diet calls for less than 2300mg, you will have to do some math to figure out how the numbers apply to you.
For example, if food has 600 mg of sodium per serving, around 26% of the RDA but 33 percent of your daily prescribed intake. That’s a significant difference.
You will also have to understand portioning. Most people don’t bother to read the serving size section of food nutrition labels, but you must understand this part of the label. It’s easy to eat a lot more than a serving size of food, especially when it’s something like cereal, chips, or crackers that are light and not very filling. Overdoing it can raise your sodium intake by a surprising amount.
The words “Low sodium” and “lower sodium” appear on some food packaging. These designations are useful for helping you make better choices, but keep in mind that “lower sodium” isn’t the same as “low sodium”; it just means that the product has less sodium than the original version. In some cases, for example, with bacon, this means that while the food isn’t as salty as the original product, it still has quite a bit of salt and should be used sparingly.
After a while, you’ll get used to reading labels, and you’ll commit to memory how much sodium is in certain foods. So you’ll know which ones to avoid and which to choose.
6. Eat more home-cooked meals
Fast food – and restaurant food in general – tends to be high in sodium. The same is true for many prepackaged meals you can purchase from the grocery store’s frozen section.
Doing more cooking at home is one of the best ways to adhere to a low sodium diet. You can choose to create your own meals out of low sodium foods, and by doing so, you’ll probably find that you’re eating a diet that is healthier overall.
There are many resources online for low-sodium recipes. You can also consider meal-prepping. Meal prepping is when you cook many meals at once, ahead of time, and freeze them so you can use them in the coming weeks. Meal prepping can make it easy for you to have a low-sodium meal at home or on the go, even when you’re busy.
7. Don’t use softened water for cooking and drinking
Water is often an overlooked source of extra dietary sodium. If you drink tap water and use a water softener, it can add to your daily salt intake. You may want to stop using a water softener or only soften your hot water and not the cold water. You could also switch to spring water or purified water with no extra sodium.
8. Avoid medications that contain sodium
Some medications contain sodium. If you have any concerns about your prescribed medications or about over-the-counter medications you’re considering using, speak with your healthcare provider. Your doctor will weigh the risks and benefits of the medicines prescribed to you and will switch any drugs that could be unsafe for you.
