Salt: Types, Uses, Side Effects, Sources, and More


Salt your body needs to work right. But having too much or too little can cause health issues. To stay healthy, check food labels to make sure you’re not eating too much salt. Try to eat a balanced diet. Healthy groups having too much salt causes high blood pressure and heart disease. But after many years of research the results are mixed. In fact, some evidence suggests that not having enough salt can be bad for you. For more research you can also visit Wikipedia.

What is Salt?

Salt is a main way we get sodium in our diet. It’s also called sodium chloride made up of 40% sodium and 60% chloride. Nowadays, people often use “salt” and “sodium” to mean the same thing. Some types of salts have extra things added, like iodine, iron, or folic acid. For instance, table salt usually has iodine added to it. Sodium is really important for our bodies to work right. It helps with things like keeping fluids balanced, keeping our nerves healthy, absorbing nutrients, and making our muscles work. Lots of foods have sodium in them, even ones that taste sweet, such as bread, cereals, cured meats, sauces, condiments, chips, crackers and soups. People have been using salt to preserve food for a long time. When there’s a lot of salt in food, it stops bacteria from growing which can make food go bad. Salt is usually made by digging it up from salt mines or by evaporating seawater or other water with lots of minerals in it. There are different kinds of salt you can buy. Some common ones are regular table salt, Himalayan pin salt, and sea salt. They might taste, feel, and look different from each other.

What are the Types of Salt?

Here are some types of sodium, you often find in kitchen, and the best ways to use each one:

  • Table
  • Kosher
  • Sea
  • Flakey
  • Fleur de sel
  • Rock
  • Pickling
  • Himalayan pink
  • Black
  • Seasoned
  • Smoked

What are the Uses of Salt?

The word “salt” comes from the Latin word “sal” which means salt. In the past, sodium was very valuable and was even used as a form of money for trading. The English word “salary” actually comes from this same root. Sodium has been used for a long time to add flavor to food and to preserve it. It’s also been used in other industries like tanning, dyeing, and making pottery, soap, and chlorine. Nowadays, it’s used a lot in the chemical industry. You can find it in many forms in the kitchen like table salt, rock salt, or kosher salt. But watch-out lots of everyday foods, from fast food to frozen chicken have high levels of salt (or sodium) hidden in them.

What are the Side Effects of Salt?

The body needs sodium to keep fluid levels balanced. Having the right balance of fluid and sodium is important for keeping the heart, liver, and kidneys healthy. Sodium helps regulate the fluids in the blood and prevents low blood pressure.

Too Little Salt:

Low sodium levels occur when there’s too much fluid in the body, such as from fluid retention. In these cases, diuretics are often prescribed to reduce fluid buildup. Other reasons for low sodium levels include:

  • Addison’s disease
  • Intestinal blockage
  • Diarrhea and vomiting
  • Underactive thyroid
  • Heart failure
  • Excessive water intake
  • Burns

When sodium levels drop in the blood, it can impact brain function. The person might feel tired and lacking in energy. They could also have muscle twitches, which might lead to seizures, loss of consciousness, coma, and even death if the sodium levels drop rapidly. In older individuals, these symptoms can be particularly serious. A study with rats showed that when they were deprived of sodium, they avoided activities they usually enjoyed. This led researchers to suggest that sodium might have antidepressant effects.

Too Much Salt:

Eating too much sodium has been connected to health issues like osteoporosis, kidney disease, and high blood pressure (hypertension), which can lead to heart disease and strokes. According to the American Heart Association (AHA), when there’s too much sodium in the blood, it pulls more water in, increasing the volume of blood. This makes the heart work harder to pump it around the body, which can stretch the walls of blood vessels over time, making them more prone to damage. High blood pressure also contributes to the buildup of plaque in arteries, raising the risk of strokes and heart disease. The AHA advises people to consume more potassium while cutting down on sodium. Potassium is thought to reduce the negative effects of sodium. Sodium has also been found to overstimulate the immune system, suggesting a link to autoimmune disease like lupus, multiple sclerosis, allergies, and other conditions. Researchers discovered that kids who eat salty foods are more likely to pair them with sugary drinks, which could increase the risk of obesity.

Which Foods are High in Salt?

The majority of sodium we eat nowadays comes from restaurant meals and packaged, processed foods. Some of the main sources of sodium for adults and children in the United States include:

  • Bread: sandwich bread, baguettes, crispbread
  • Processed meats: salami, bacon, pastrami, ham, sausages
  • Salty snacks: chips, French fries, crackers, salted nuts
  • Cheese and cheese products: Brie, cheese in can, string cheese, cheddar, mozzarella
  • Grain-based desserts: Muffins, cakes, cookies
  • Soups: Canned, frozen, powdered

Always remember to check the labels and nutrition information on packaged foods. They give important details, including how much sodium is in each serving. To find low sodium quickly, look for terms like “low sodium” or “reduced sodium”. You can also compare the sodium amount per serving or per 100 grams with other products you’re thinking of buying.

How Much Salt Do You Eat?

The average American currently eats more than 3400 MG or 3.4 grams of sodium every day. Since it is 40% sodium, that’s about 8500 MG or 8.5 G of sodium. The American Heart Association (AHA) and the World Health Organization (WHO) suggest not consuming more than 1500 mg or 1.5 g of sodium per day, which is just over half a teaspoon of table salt. People with conditions like high blood pressure, diabetes, or cardiovascular disease should be extra careful to stay under the 1500 mg limit. But what does 1500 mg of sodium look like?

  • 1 egg up to 140 mg
  • 230 g of fresh mill around 50 mg
  • 200 g of plain yogurt 40 mg
  • 50 g of raw celery 140 mg
  • 60 g cooked spinach 120 mg

Other vegetables typically have low sodium levels, but canned vegetables often contain added sodium, making them much higher in sodium. Dietitians recommend avoiding adding extra sodium to meals since many processed or packaged foods already contain enough sodium. It’s important not to give sodium to infants under one year because their kidneys are not fully developed.

Is Salt Healthy or Unhealthy?

It is necessary for your body to work properly and for good health. However, having too much or too little sodium can be harmful. Just like other nutrients and foods, having a balanced diet is important. Many healthy foods, like fruits, vegetables, grains, raw nuts, legumes, and seeds naturally contain very little sodium or none at all. Eating a diet rich in these whole foods can lower your risk of diseases linked to high sodium chloride intake. For instance, following diets like the Dietary Approaches to Stop Hypertension (DASH) diet or the Mediterranean diet can help lower high blood pressure. These diets are high in vegetables, whole grains, fruits, low-fat dairy, and lean protein, but low in sugar, unhealthy fats, and red meat. If your healthcare provider has advised you to cut back on sodium, it might be helpful to learn more about these two diet plans.

What is the Difference Between Sea Salt and Table Salt?

There are several differences between table salt and sea salt, including how they’re made. However, they both have the same amount of sodium. Both salts are useful in cooking. Table salt is mined from deposits and processed into fine crystals, while sea salt is made by evaporating seawater. Many people think sea salt is healthier because it’s a natural source of sodium. Table salt is stripped of some nutrients like magnesium, calcium, and potassium during processing, but it’s often fortified with iodine which is important for thyroid health. Sodium is essential for our bodies, but we mainly get it from salt and processed foods. Doctors advise limiting salt intake because too much sodium can lead to dehydration and heart disease, including high blood pressure.

Table Salt vs. Sea Salt:

Many people see sea salt as a healthier option compared to table salt. Sea salt is made by evaporating seawater making it a natural source of sodium. Table salt, on the other hand, is obtained by mining salt deposits and then processed into fine crystals for easy mixing into food. Chefs often use sea salt in recipes because of its coarse texture and stronger taste, preferred by some. Although many believe sea salt is healthier it actually has the same sodium content as table salt. Despite common misconceptions, both typically contain 40% sodium by weight. For instance, a teaspoon of table salt contains about 2300 mg of sodium. Because sea salt crystals are larger, fewer can fit in a teaspoon. This might lead people to think sea salt has less sodium. Sea salt also contains additional minerals like:

  • Magnesium
  • Calcium
  • Potassium

However, table salt is usually fortified with iodine. In summary, while sea salt may offer additional minerals, it’s not lower in sodium compared to table salt.

What are the Health Benefits of Table Salt and Sea Salt?

Sodium is crucial for good health, so it’s important not to completely eliminate it from your diet. Salt, which contains sodium, helps regulate blood pressure and is essential for nerve and muscle function. It’s needed for normal cell function and to keep the blood’s acid balance in check. Table salt includes iodine, another essential nutrient. Without enough iodine, people can develop goiter and experience various symptoms. Lack of iodine can also lead to poor growth and cognitive issues in children. In the United States, iodine deficiencies are rare because many products, including table salt, have added iodine. However, the risk of low iodine might be higher in Europe and other parts of the world, especially among those who don’t consume dairy, baked goods, or table salt. Unlike table salt, unprocessed sea salt doesn’t contain iodine. But, as mentioned earlier sea salt naturally contains small amounts of minerals like magnesium, calcium, and potassium. Although sea salt’s mineral content is minimal, people can get these nutrients in higher amounts from other healthy foods.

What are the Signs and Symptoms of Iodine Deficiency?

According to a 2017 study, around one-third of people may be deficient in iodine. Here are some symptoms that could indicate a person has an iodine deficiency:

  • Putting on weight
  • Feeling weak
  • Feeling tired
  • Losing hair
  • Drying skin
  • Feeling cold
  • Having a slow heart rate
  • Memory problems
  • Pregnancy complications
  • Heavy or irregular periods
  • Swollen neck

What are the Health Risks of Table salt and Sea Salt?

Too much sodium can contribute to several health conditions, including:

  • High blood pressure
  • Heart disease
  • Stroke
  • Heart attacks

Despite this, people still need the right amount of salt in their diet to stay healthy. According to the Dietary Guidelines for Americans, the average American consumes about 3440 mg of sodium per day, which is too much. The American Heart Association (AHA), recommends eating less than half of this amount, aiming for 1500 mg per day. Reducing sodium intake can lower the risk of heart disease and high blood pressure. Countries around the world, through the World Health Organization (WHO), have committed to reducing global sodium intake by 30% by 2025. Interestingly, most of the sodium people consume doesn’t come from adding it to homemade meals. Instead, more than 75% of the sodium in people’s diets comes from processed foods. Besides processed and packaged foods, people should also be mindful of the high sodium content in poultry, cheese, and bread. Sometimes, manufacturers add anticaking agents to prevent clumping. These additives might include:

  • Potassium ferrocyanide
  • Calcium silicate
  • Silicon dioxide
  • Yellow prussiate of soda
  • Iron ammonium citrate

The Food and Drug Administration (FDA) have said these additives are safe to use in sodium to prevent clumping.

What are the Intake Recommendations of Table Salt and Sea Salt?

The American Heart Association (AHA) advises people to aim for a salt intake of less than 1500 mg per day. On the other hand, the Dietary Guidelines for Americans recommend limiting sodium intake to less than 2300 mg per day for adults and children over 14 years old. For children under 14 years old, the maximum recommended sodium intake depends on their age and gender.

Can Salt Make You Weight Gain?

Sodium is a vital nutrient for life. It’s essential for various bodily functions, including regulating fluid and blood pressure, transporting nutrients, and supporting nerve cell function. However, many people consume too much sodium, mainly in the form of sodium chloride or table salt. Eating excessive amounts of added salt can raise your risk of health problems, such as strokes, heart disease, or autoimmune disease. You might also be curious about whether sodium contributes to weight gain.

Excess Dietary Salt May Make You Retain Water:

Many people link excessive sodium in the diet with retaining fluids. This is because consuming a lot of sodium prompts your body to hold onto water. A recent study discovered that high sodium intake increases thirst. Your body uses the extra fluid you drink to dilute the excess sodium it can’t get rid of quickly enough. However, even though you’re drinking more fluid, your urine volume doesn’t change, meaning the extra fluid stays in your body. So, a sudden spike in sodium intake might result in gaining some weight due to fluid retention. This is why some individuals feel bloated after eating high sodium foods like take-out or salty restaurants meals. It’s essential to know that this fluid retention is usually temporary. Body fluid levels typically go back to normal after a few days. However, while some research indicates that higher sodium intake drives increased fluid intake, other studies haven’t shown this connection. For instance, a small study found that although a high sodium diet led to weight gain and water retention in 10 healthy men, consuming more sodium wasn’t linked to drinking more fluids. In fact, the study found that a daily intake of 12 grams led to reduced fluid intake. Understanding the relationship between dietary salt intake and fluid balance is complex. Further research is necessary to fully grasp how high sodium intake might affect the body’s fluid levels.

Many Foods that are High in Added Salt are High in Calories:

Foods high in salt are often high in calories too. For instance, fast foods, fried foods, boxed macaroni, and cheese, frozen meals, creamy pasta dishes, and pizza are typically loaded with both salt and calories. Consuming too many high-salt, high calorie foods can contribute to weight gain. Studies have also shown that a high sodium intake may increase the risk of obesity, regardless of calorie  intake. One study involving 1243 children and adults found that those with higher urinary sodium levels were more likely to be obese or overweight. High sodium chloride intakes were linked to higher levels of body fat in both children and adults. The study also revealed that each additional gram of sodium consumed per day was associated with a 28% and 26% higher risk of obesity in children and adults respectively. Another study with 9162 participants found that consuming more than 2300 mg sodium per day was significantly linked to a higher risk of obesity and abdominal fat compared to a moderate sodium intake of 1500-2300 mg per day. Both studies concluded that sodium intake was associated with weight gain and obesity, even after considering total calorie intake and other factors like physical activity levels. Although the exact mechanism isn’t fully understood, a high salt diet might directly contribute to fat accumulation in the body.

How to Cut Back on Added Salt:

For most people, the naturally occurring sodium in foods like eggs and shellfish isn’t usually a concern. However, it’s essential to keep an eye on your intake of added salt to avoid consuming too much. Typically, the majority of added salt in our diets comes from highly processed foods. Here are some high-sodium foods to cut down on to reduce your added salt intake:

  • Highly Processed and Salty take out Foods: pizza, street tacos, hamburgers, chicken nuggets French fries, etc.
  • Salty Packaged Snacks: Chips, pork rinds, pretzels, etc.
  • Processed Meats: Jerky, Bacon, cured meat, salami, sausages, etc.
  • Salty Condiments: Salad dressing, soy sauce, hot sauce, etc.
  • High Salted Boxed or Canned Meals: Pre-packaged pasta and rice dishes, canned soups, canned ham, boxed potato casseroles, etc.

Moreover, adding too much sodium to homemade meals can significantly increase your overall salt intake. Try reducing the amount of sodium you add to your dishes, and taste your food before adding extra sodium. You can also enhance the flavor of your meals using lemon juice, fresh herbs, garlic, and spices instead of sodium.
