Processed cheese slices are a convenient and long-lasting food product, commonly used in fast food and in many households. However, they have been deemed unhealthy due to their high sodium content, unhealthy fats, artificial additives, and low-quality nutrients. For example, a single slice of processed cheese can contain up to 300 mg of sodium, which is nearly 15% of the daily recommended intake. Furthermore, the presence of artificial colours, preservatives, emulsifiers, and other additives means that some processed cheese slices cannot be legally labelled as cheese, and are instead referred to as cheese food, cheese spread, or cheese product.

What You'll Learn
High sodium content
Processed cheese slices are often criticised for their high sodium content. While natural cheese is made using milk, salt, cultures, and rennet, processed cheese often contains additional salt, as well as other additives, to enhance flavour and act as a preservative. This increases the product's sodium content, with a single slice of processed cheese providing up to 300 mg of sodium, or nearly 15% of the daily recommended intake.
High sodium intake is linked to various health risks. Excessive salt consumption leads to increased water retention, which raises blood pressure and puts strain on the heart, potentially causing hypertension. The high sodium levels also force the kidneys to work harder to filter blood, which can contribute to the development of kidney disease over time.
The presence of pure sodium, a purified form of salt, in processed cheese products is concerning. Additionally, some processed cheese slices contain trisodium phosphate, an emulsifier that contributes to a smooth texture. However, trisodium phosphate is also used in cleaners and stain removers, raising questions about its suitability for human consumption.
The high sodium content in processed cheese slices is a significant factor in the criticism of these products. While they may be convenient and have a long shelf life, the potential health risks associated with excessive sodium intake cannot be ignored. It is important for consumers to be aware of the sodium levels in the food they consume and to make informed choices to maintain a balanced and healthy diet.

Artificial additives
Processed cheese is often made more appealing to consumers by enhancing its colour, texture, and flavour through the use of artificial additives. While these additives contribute to the cheese's long shelf life and smooth consistency, they can also pose significant health risks.
One common additive is potassium phosphate, which acts as an emulsifier and preservative. However, it may trigger allergic reactions in some individuals. Tartrates, another type of additive, have been linked to diarrhoea.
Coloring agents such as Yellow 6 and yellow tartrazine are used to make the cheese more visually appealing, but these additives have been banned by the European Union due to their potential to promote tumour growth in animal studies.
Isolated and artificial vitamins are also added to processed cheese, but these forms cannot be properly absorbed by the body and may even be toxic. Additionally, the pure sodium added to processed cheese is a purified form of salt that can contribute to excessive salt intake, leading to health issues such as hypertension and kidney damage.
Processed cheese may also contain added sugars, which can negatively impact blood sugar levels. While some brands may offer higher protein content, the high sodium and fat levels can offset this benefit.

Low-quality nutrients
Processed cheese is often considered unhealthy due to its low-quality nutrients. While it is a convenient and long-lasting food item, it undergoes significant processing, which alters its nutritional value compared to natural cheese.
Firstly, processed cheese may contain lower-quality forms of essential nutrients like calcium. For example, Kraft Singles provide a significant amount of calcium, while Philadelphia, another processed cheese, offers only a minimal amount. This variation in nutrient content even within the category of processed cheese highlights the inconsistency in the quality of nutrients offered by these products.
Secondly, processed cheese often contains isolated and artificial vitamins that are added during fortification. However, these synthetic forms of vitamins may not be properly absorbed by the body and could even be toxic. Therefore, the vitamins added to processed cheese may not provide the same benefits as those naturally occurring in whole foods.
Additionally, processed cheese often contains dairy by-products, which are modified milk ingredients such as whey, protein concentrates, milk fat, and dehydrated dairy powder. These by-products are used to extend the shelf life and improve the functionality of the cheese but may not offer the same nutritional benefits as pure milk.
Furthermore, the long list of ingredients in processed cheese products indicates the presence of numerous additives and artificial substances. These additives may include emulsifiers, stabilizers, preservatives, and artificial flavourings, which are not naturally occurring in cheese and may detract from the overall nutritional quality of the product.

High trans fat content
Processed cheese slices are a convenient and popular food item, often used in sandwiches, burgers, and other melted cheese applications. However, one of the major concerns with processed cheese slices is their high trans fat content, which can have negative impacts on health.
Trans fats are created through an industrial process that adds hydrogen to vegetable oil, a process called hydrogenation. This is done to make the oil harder and more stable, and it is commonly used in margarine and snack foods, as well as in the production of processed cheese. The hydrogenation process creates a type of fat that is even less healthy than saturated fats, and it is now recognized that trans fats can have significant negative impacts on health.
The high trans fat content in processed cheese slices is a concern because consuming trans fats has been linked to an increased risk of heart disease, one of the leading causes of death worldwide. Trans fats can raise "bad" LDL cholesterol levels, which can lead to a build-up of plaque in the arteries, increasing the risk of heart attack and stroke. In addition, trans fats can lower "good" HDL cholesterol levels, further adding to the risk of cardiovascular problems.
Another issue with the trans fats found in processed cheese slices is their potential impact on inflammation in the body. Some research suggests that trans fats can promote inflammation, which is a key driver of many chronic diseases, including heart disease, type 2 diabetes, Alzheimer's disease, and certain cancers. By increasing inflammation, trans fats may contribute to the development and progression of these serious health conditions.
It is important to note that many countries and health organizations now recommend limiting trans fat intake as much as possible. For example, the World Health Organization has called for the elimination of industrially-produced trans fats from the global food supply, recognizing the significant health risks associated with these fats. This shift in guidance reflects the growing body of evidence linking trans fat consumption to adverse health outcomes.
In conclusion, the high trans fat content of processed cheese slices is a significant concern due to the well-established links between trans fat consumption and an increased risk of heart disease, among other health issues. To support better health outcomes, it is advisable to limit the consumption of processed cheese slices and other foods high in trans fats, opting for healthier alternatives whenever possible.

High sugar content
Processed cheese products are often high in sugar content. This added sugar enhances the flavour of the cheese and makes it more appealing to consumers. However, it can lead to blood sugar spikes, especially in products like Kraft Singles or Velveeta, which have higher sugar content than Philadelphia. The high sugar content in processed cheese can be concerning, especially for individuals with diabetes or those who are trying to manage their blood sugar levels.
The sugar in processed cheese is not naturally occurring, as in the lactose found in milk, but rather added as a form of sweetener or flavour enhancer. This means that it can contribute to an excessive intake of added sugars, which have been linked to various health issues. Excessive consumption of added sugars can lead to weight gain, tooth decay, and an increased risk of chronic conditions such as obesity, type 2 diabetes, and heart disease.
Additionally, the high sugar content in processed cheese can also affect the overall nutritional value of the product. While cheese is often associated with being a good source of calcium and protein, the high sugar content in some processed cheese products can detract from these nutritional benefits. For example, Kraft Singles, known for their high calcium content, also have a significant amount of sugar, creating an imbalance in their nutritional profile.
It is worth noting that not all processed cheese products have the same sugar content. Some brands or varieties may have lower sugar levels, making them a slightly better option in terms of sugar intake. However, it is important to read the ingredient lists and nutrition labels carefully, as the sugar content can vary significantly between different types of processed cheese.
Overall, the high sugar content in processed cheese slices is a cause for concern. While it enhances the flavour and makes the product more appealing to consumers, it can also lead to potential health risks associated with excessive sugar consumption. Therefore, it is important to be mindful of the sugar content when consuming processed cheese products and to choose lower-sugar options whenever possible.
