What is the best way to absorb sodium?

Sodium is absorbed mainly through salt

Unlike many micronutrients, of which we tend to take in too little, the reverse is true for sodium: most people consume excessive amounts of sodium.6 On average, men consume 3,216 mg/day and women 2,379 mg/day.7 This is mainly due to the fact that in industrialized countries salting is excessive and our body, due to evolution and the low sodium intake in the past, uses the mineral very sparingly.8

Sodium is a water-soluble bulk element. This means that it is excreted via the kidney. In order to protect the organ and avoid other risks from an over-supply of sodium, the question therefore arises as to what the appropriate intake is and how you can reduce it if necessary.

How much sodium is healthy?

Unlike many other nutrients, the German Nutrition Society (DGE) has not set a minimum intake for sodium, but a recommended estimate. This is 1,500 mg per day from the age of 15 and also applies to Pregnant and breastfeeding women.2

Somewhat higher is the amount of European Food Safety Authority (EFSA) fixed estimated value of 2,000 mg.3 In the following table you will find the reference values of the DGE for the daily sodium intake of Children and teenagers.

Children and teenagersRecommended intake in mg
1 to under 4 years400
4 to under 7 years500
7 to under 10 years750
10 to under 13 years1.100
13 to under 15 years1.400
Reference values in mg for the daily sodium intake of for children and adolescents2

What are the functions of sodium?

Sodium is associated with the minerals Calcium, Potassium and Chloride for the regulation of the Water balance responsible. The mineral also regulates the Acid-base balance and Blood pressure. Furthermore, it serves to maintain the cell membrane potential and to transport molecules across the cell membrane.1,5

The Sodium functions brief and concise overview:

  • Regulation of the water balance
  • Regulation of the acid-base balance
  • Blood pressure regulation
  • Preservation of the membrane potential
  • Cellular transport of molecules

Is it possible to take in too much sodium?

Excessive sodium intake increases the risk of developing Hypertension and consequently cardiovascular diseases. So far, only the US Department of Agriculture has set a maximum intake limit of 2,300 mg per day.4 To reduce the risk of high blood pressure, it is also recommended to increase the consumption of foods containing potassium and low in sodium.9

When it comes to Acute overuse with sodium, the water balance gets out of balance and confusion, overexcitability, convulsions or even coma occur.1

Is a sodium deficiency possible?

As already mentioned, we tend to consume too much sodium rather than too little - which is why a sodium deficiency is also a correspondingly rare phenomenon. In exceptional cases, extreme sweating, diarrhea or vomiting can lead to deficiency symptoms. Then occur Symptoms such as low blood pressure, heart palpitations, convulsions, dry skin or a disturbance of the neuronal transmission of stimuli.

Which foods contain a lot of sodium?

To make sure you don't take in too much sodium, it's a good idea to know foods that are high in sodium. About 75 percent of sodium intake is due to the consumption of processed foods.5 In Germany, these are mainly Bread, meat, sausage and dairy products, in particular Cheese.7 The largest proportion is consumed as sodium chloride (i.e. table salt). In Europe, the average consumption of table salt is 8 to 11 grams per day, which corresponds to about 3 to 5 grams of sodium.5

In order to maintain a high sodium intake and the correspondingly increasing Reduce risk of cardiovascular disease, you should Avoid foods high in sodium, processed foods and foods containing meat, as well as many foods rich in potassium, such as Fruit and vegetables eat

Tip: You can find more details about this in the separate article on Potassium.

How to reduce your sodium intake

Here are some more practical tipsto reduce your sodium intake.

It's best to cook fresh at home a lot, using herbs or Celery salt for seasoning and minimize the amount of salt. Also pay attention to the salt content when buying ready-made products, reduce your meat consumption and increase the amount of fruits and vegetables in your diet.9,10

Notice: Even more important than a reduction in sodium consumption is that the intake of potassium is higher than that of sodium. This greatly reduces the risk of cardiovascular disease.

What do vegans need to consider when it comes to sodium?

According to the German Nutrition Society (DGE), sodium is considered to be not considered a potentially critical nutrient with a plant-based diet.11 This means that vegans and vegetarians do not have to pay special attention to sodium supply.

A vegan diet offers with regard to the sodium balance even advantagesbecause, on average, vegans eat less processed food and, logically, no meat.

Should sodium be supplemented?

Supplementation with sodium is usually not necessary. Therefore, I will not make a recommendation of a particular supplement here.

Hi, my name is Julian and I am a trained vegan nutritionist. In 2016 I started to get involved with veganism and quickly learned how big an impact our diet has on the environment and how diverse plant-based diets can be. That's why I want to inspire you to get involved with veganism too.
