Salt is an essential nutrient that plays a crucial role in preserving food and maintaining the body's fluid balance. While the body needs a small amount of salt to function properly, excessive salt intake can lead to adverse health effects. The majority of the salt in our diets comes from packaged and processed foods, rather than the salt added during cooking or at the table. To maintain a healthy balance, it is recommended to limit salt intake, especially for babies and young children, and opt for alternative seasonings like herbs, spices, and black pepper. Understanding food labels and reducing packaged food items can help lower daily salt intake. Additionally, ensuring adequate potassium and water intake can counterbalance the effects of excess salt consumption.

What You'll Learn
Salt is necessary for the body in small amounts
Salt, or sodium chloride, is essential for the human body to function properly. It is composed of about 40% sodium and 60% chloride. While it is often advised to minimise salt intake, it is important to recognise that a small amount of salt is necessary for the body.
The human body requires a small amount of sodium to conduct nerve impulses, contract and relax muscles, and maintain the proper balance of water and minerals. Sodium plays a crucial role in managing fluid balance, and a severe lack of it could lead to dehydration. Dehydration can have serious health consequences, especially for older adults and people with malnutrition. Additionally, a low salt diet can cause hyponatremia, a condition characterised by abnormally low sodium levels in the blood, which can lead to neurological problems, seizures, and even death.
The body actively regulates sodium levels. If sodium levels are too high, we become thirsty, prompting us to drink more water, and our kidneys increase the rate at which they excrete sodium. Conversely, if sodium levels fall too low, we may experience symptoms such as sluggishness, lethargy, muscle twitches, seizures, and in severe cases, loss of consciousness, coma, or death.
It is worth noting that most people consume more salt than is necessary. The AHA and the World Health Organization recommend not exceeding a daily sodium intake of 1,500 mg, or just over half a teaspoon of table salt. However, the average American consumes about 3,400 mg of sodium daily, which is far more than our bodies need. This excess salt intake has been linked to various health concerns, including high blood pressure, heart disease, stroke, and osteoporosis.
In conclusion, while it is generally advisable to limit salt intake, it is important to recognise that a small amount of salt is necessary for the body to function optimally. The key lies in finding the right balance, as too much or too little salt can lead to medical problems.

Processed foods contain high levels of sodium
Processed foods are "any food that has been changed from its original, raw form". This includes packaged, frozen, and convenience foods, as well as processed meats. More than 70% of the average person's sodium intake comes from these processed and restaurant foods.
Many processed foods are high in sodium, which is used for curing meat, baking, thickening, retaining moisture, enhancing flavour, and as a preservative. Some common food additives, like monosodium glutamate (MSG), sodium bicarbonate (baking soda), sodium nitrite, and sodium benzoate, also contain sodium. In a review of brand-name foods sold in U.S. stores, salad dressing averaged 304 mg of sodium per 2-tablespoon serving, while a slice of frozen pizza averaged 765 mg. Processed meats are particularly high in sodium, with a single hot dog containing up to 578 mg of sodium.
High sodium intake is linked to several health issues, including high blood pressure, which is a major cause of stroke and heart disease. As such, it's important to monitor and adjust one's consumption of processed foods that are high in sodium. Reading the Nutrition Facts panel and ingredients label on food products can help individuals make informed choices about their sodium intake.
To reduce sodium intake, individuals can opt for reduced-sodium versions of sauces, such as soy sauce, or make their own. Canned tomato products without added salt are also widely available. When purchasing meat, it's advisable to choose fresh meat, poultry, and seafood instead of processed varieties, and to check if salt water or saline has been added. For snacks, low-sodium or no-salt-added options are recommended. Additionally, herbs and spices can be used instead of salt to add flavour to meals.

Sodium and salt are not the same thing
While the terms "sodium" and "salt" are often used interchangeably, they are not the same thing. Sodium is a mineral and a key component of salt, which is also known as sodium chloride because it is made up of 40% sodium and 60% chloride. Salt is a chemical compound added to food to enhance its flavour and preserve it.
Sodium is a nutrient crucial to numerous bodily functions, such as regulating blood pressure and maintaining proper fluid balance. It is naturally found in many foods, especially processed foods containing preservatives. However, excessive sodium consumption can increase the risk of health problems, including high blood pressure, cardiovascular issues, and heart disease.
On the other hand, salt is what we add to our food. While salt can improve the taste of food and prolong its shelf life, it is not a necessary addition to our diet. In fact, adding too much salt to our food can be detrimental to our health. The current health recommendation is to limit daily sodium intake to no more than 2,300 milligrams for individuals aged 14 and older.
To reduce sodium intake, it is important to read food labels and choose options with lower sodium content. Eating more home-cooked meals and using herbs, spices, and other flavour enhancers instead of salt can also help reduce sodium intake. Additionally, limiting highly processed foods and choosing fresh or frozen lean meats, chicken, seafood, eggs, or dried beans can help lower sodium consumption.
In summary, while sodium and salt are closely related, they are not interchangeable. Sodium is a mineral and a component of salt, while salt is a chemical compound added to food. Understanding this distinction is crucial for maintaining a healthy diet and managing health risks associated with excessive sodium intake.

Salt is addictive
Salt consumption activates the brain's reward system, inducing cravings and the search for salted food. This is due to the activation of opioid receptors in the brain's emotional area, the central amygdala, which is involved in a range of emotions, including fear and positive emotions like eating or socialising. When you are salt-depleted, such as when you are hungover, your craving for salt increases significantly.
The massive and lifelong use of sodium in food and the lack of success in dietary salt restriction despite public health campaigns and recommendations support its classification as a clinical addiction. The overconsumption of salt is responsible for five times more deaths than the Australian road toll. It is evident that a greater amount of salty food is progressively needed to achieve the same gratifying response, leading to a vicious cycle of increased salt intake.
High sodium intake is associated with negative health outcomes, including an independent correlation with high blood pressure, which increases the risk of cardiovascular disease, chronic kidney disease, and morbid obesity. The high quantity of salt in processed food is likely a major cause of the global pandemic of hypertension.
To reduce salt intake, it is recommended to limit the amount of salt added during cooking and to taste food before adding extra salt. Additionally, understanding food labels can help choose foods that are low in salt, and trying to use less of sauces that are high in salt, such as soy sauce, ketchup, and mayonnaise.

Salt is a natural preservative
Salt is also a natural mineral composed of two elements: sodium and chloride. Sodium is an essential nutrient and electrolyte that helps maintain a balance of body fluids, keeping muscles and nerves functioning smoothly. It also promotes healthy hydration levels and is necessary for the body to function properly.
However, it is important to be mindful of salt intake, as too much salt can lead to high blood pressure, which is a major cause of stroke and heart disease. The body only needs a small amount of sodium to work properly, and most people consume more than enough salt in their diets. This is because salt is often added to packaged and processed foods, so it can be difficult to reduce salt intake without cooking at home and avoiding these foods.
To ensure you are getting the right amount of salt, it is recommended to keep salt intake stable and ensure you are getting enough potassium and water, as these can help regulate sodium levels in the body.

Frequently asked questions
The recommended daily intake of salt varies depending on age and level of physical activity. Adults should have no more than 6g of salt a day, which is about 1 level teaspoon. The American Heart Association (AHA) recommends that people aged 14 and over consume no more than 2,300 mg of sodium per day, while serious athletes may benefit from adding a bit more salt to their home-cooked meals.
Salt is necessary for the body to function properly, but too much salt can lead to high blood pressure, which is a major cause of stroke and heart disease. There is also evidence that a high-salt diet increases the risk of stomach cancer. On the other hand, a diet too low in sodium may increase the risk of dehydration.
Packaged and processed foods are often high in salt, including bread, breakfast cereals, meat products, ready meals, and sauces like soy sauce, ketchup, and mayonnaise. Some foods that don't taste salty can still be high in sodium, such as pastries and cereals.
Cooking at home with fresh ingredients is the easiest way to cut down on salt. You can also try adding flavour to your food with herbs, spices, black pepper, garlic, chilli, or lemon juice instead of salt. Potassium-rich foods like bananas, potatoes, and coconut water can help regulate sodium levels in the body.
