Low sodium diet

Source: Wikipedia, the free encyclopedia.

A low sodium diet is a diet that includes no more than 1,500 to 2,400 mg of sodium per day.[1]

The human minimum requirement for sodium in the diet is about 500 mg per day,[2] which is typically less than one-sixth as much as many diets "seasoned to taste". For certain people with salt-sensitive blood pressure or diseases such as Ménière's disease, this extra intake may cause a negative effect on health.

Health effects

A low sodium diet has a useful effect to reduce blood pressure, both in people with

diastolic blood pressure by 2.1 mmHg.[3]

Advising people to eat a low salt diet, however, is of unclear effect in either hypertensive or normal tensive people.

congestive heart failure, but the article was retracted in 2013.[5] The article was retracted by the journal when it was found that two of the studies cited contained duplicate data that could not be verified.[6]

A doctor might prescribe a low sodium diet for patients with diabetes insipidus.

A 2021

controlled trials in people with chronic kidney disease at any stage, including those on dialysis, found high-certainty evidence that reduced salt intake may help to lower both systolic and diastolic blood pressure, as well as albuminuria.[7] However there was also moderate certainty evidence that some people may experience hypotensive symptoms, such as dizziness, following sudden sodium restriction. It is unclear whether this affects the dosage required for anti-hypertensive medications. The effect of salt restriction on extracellular fluid, oedema, and total body weight reduction was also uncertain.[7]

Food and drink contents

Sodium occurs naturally in most foods. The most common form of sodium is

baking soda (sodium bicarbonate), and sodium benzoate
.

Because large amounts of salts are given out by regenerative

water softeners, over 60 cities in Southern California have banned them because of elevated salt levels in ground water reclamation projects. Water labeled as "drinking water" in supermarkets contains natural sodium since it is usually only filtered with a carbon filter and will contain any sodium present in the source water.[8]

High sodium content

Condiments and seasonings such as

cured meats
have high sodium content.

Low sodium content

Unprocessed, fresh foods, such as fresh fruits, most vegetables, beef, poultry, fish and unprocessed grains are low in sodium. Low– or no–sodium products, and corresponding versions of products otherwise high in sodium, can be found in stores as well as online. Salt substitutes such as potassium chloride may be used to provide a similar taste to salt while reducing sodium intake, and flavor additives such as monosodium glutamate can help reduce sodium intake by enhancing other flavors.[10]

Other foods that are low in sodium include:

  • Seasonings: Black, cayenne, or lemon pepper, mustard, some chili or hot sauces
  • Herbs: Dried or fresh garlic, garlic/onion powder (no salt), dill, parsley, rosemary, basil, cinnamon, cloves, paprika, oregano, ginger, vinegar, cumin, nutmeg
  • Most fresh fruits and vegetables, exceptions include celery, carrots, beets, and spinach[citation needed]
  • Dried beans, peas, rice, lentils
  • Macaroni, pasta, noodles, rice, barley (cooked in unsalted water)
  • Honey, sugar
  • Unsalted butter
  • Unsalted dry curd cottage cheese
  • Fresh beef, pork, lamb, fish, shrimp, egg
  • Milk, yogurt
  • Hot cereals/Porridge
  • Club soda, coffee, seltzer water, soy milk, tea[11]
