Does salt cause inflammation?

Salt, sodium, and inflammation are tightly linked. High salt intake can lead to high blood pressure, increasing the risk of heart disease, stroke, and cardiovascular events. There is also evidence that excess dietary salt may be associated with chronic inflammatory diseases such as rheumatoid arthritis.

However, there does appear to be some confusion about how much salt is "too much." The World Health Organization (WHO) recommends limiting salt to 5 grams per day for adults, but critics say current evidence shows no need to go below 3 grams per day.


The debate's still out on whether you should cut back on table salt or not, but one thing scientists do agree on is that eating too much-processed food high in both fat and sodium -- which means many processed foods made by companies has been linked to obesity, high blood pressure, high cholesterol, and cardiovascular disease.

According to the Centers for Disease Control (CDC), more than 1 in 3 American adults are obese, which can lead to serious health problems like diabetes, heart disease, and stroke. Obesity-related conditions are estimated to cause nearly 112,000 deaths each year.

 And that's just in America. A 2015 study found that worldwide obesity kills around 6 percent of people while underweight bodies kill about 2 percent. It's a good argument for making fresh food from scratch rather than relying on convenience foods laden with salt and fat.

Can you get inflammation from eating too much salt?

Too much salt, which is measured in milligrams of sodium, does appear to cause inflammation. A 2011 study published in the journal Nutrition found that diets high in salt (5 grams per day) were linked to greater levels of inflammation than lower-sodium diets (less than 3 grams per day). The researchers suggested that reducing dietary salt would be one way to decrease systemic inflammation and its related complications.

Another small study of young, healthy subjects published in 2013 showed that a high-sodium diet (5 grams per day) increased levels of C-reactive protein, a biomarker for inflammation.

 Researchers concluded that dietary salt intake plays a "significant role in inflammatory processes."

It's not only the amount of salt you eat, but also its source. Many prepared and processed foods contain high levels of sodium in the form of sodium nitrite, disodium phosphate, and monosodium glutamate (MSG). These food additives help to enhance flavor and preserve shelf life.

Salt is necessary for healthy brain function and helps to control blood pressure and water balance throughout your body. The American Heart Association recommends limiting your daily sodium intake to 1,500 mg or less per day; it's wise to keep this number under 2,300 milligrams if you have heart disease or are at risk for developing it. But since it can be tough to track the sodium you eat, focus on avoiding processed foods that are high in salt.

Does salt cause inflammation in joints?

Some studies have linked high-salt diets to rheumatoid arthritis. In a 2005 study, researchers measured the "netload" of salt -- the difference between how much sodium and potassium people consumed in their diet. Over 10 years, study participants who ate a higher net load of salt were more likely to develop rheumatoid arthritis than those who ate a lower netload.

No research has been done on whether a low-sodium diet would prevent inflammation in joints. However, avoiding processed foods that are high in both fat and sodium is smart regardless of your health status or disease risk.

If you're concerned about inflammation in your joints, talk with your doctor about your specific risks for heart disease or other conditions that may be worsened by a high-sodium diet.

Is it okay to eat table salt while on a low carb/keto diet?

There is no research we can link to which specifically looks at the use of eating table salt on a low-carbohydrate or ketogenic diet (we don't know of any such studies). However, if you read the article above, the current evidence suggests that salt may increase inflammation in some people - and it isn't always easy to predict who this would affect. 

Since many people with diabetes and metabolic syndrome often have elevated markers of inflammation, we'd certainly be concerned about an increased intake of salt (although there's also not much direct research we could point you to for confirmation either).

Can salt make your face swell?

Yes, salt can make your face swell and remain puffy. When you eat large amounts of salt, the kidneys cannot keep up with removing all of it from your body. The excess sodium is then flushed into your bloodstream and travels to cells throughout your body including facial tissue such as skin and muscles.

Salt makes the osmotic pressure in these tissues increase which causes fluid to leave the capillaries and enter that area's cells where water accumulates causing puffiness.

Is it bad for your health if you eat sugar and salt?

Salt is not sugar, but they go well together in sweetened drinks like colas which are very unhealthy. Salt gives the same taste to food but considers what it does; It makes you thirsty so you drink more of the sugary stuff (the carbonated drinks basically make your blood thicker due to higher concentrations of glucose). 

Then when your body tries to rid itself of this high volume of liquid through urination, you may actually get dehydrated. Finally, the cancer-causing preservative that is added to these drinks (even though it is supposed to be filtered out and safe for consumption) does not help your health either. There are so many problems eating sugars and salts together that we cannot cover all of them here, but just know that it's not good for you - ever!

How much salt can you have with water?

Salt is sodium chloride and is essential to our diet in moderation with foods. Besides being a common seasoning, it also has uses as a preservative and is used in certain medical procedures that require the interruption of bodily fluids. In the average person's diet, sodium intake varies depending on age, gender, weight, and physical activity level. 

But generally speaking one should not consume more than 1/2 teaspoon per day to avoid too much iodine intake or fluid retention issues for some people which can lead to hypertension. It all depends on your specific health status so speak with your doctor if you want a more personalized recommendation based on your overall health goals when it comes to restricting sodium for overall better long-term results.
