Cheese slices, particularly processed cheese slices, have been criticized for their negative health impacts. While cheese is a rich source of calcium, vitamins, and minerals, it has also been associated with an increased risk of obesity, high blood pressure, and heart disease. This is due to the high levels of sodium, saturated fat, cholesterol, and lactose present in cheese slices, as well as the preservatives, additives, and artificial ingredients used to extend their shelf life. However, some argue that cheese slices are not inherently unhealthy, but rather, it is the overconsumption of these slices that may lead to adverse health effects.

What You'll Learn
High saturated fat content
Cheese slices have been associated with an increased risk of heart disease due to their high saturated fat content. Saturated fats make up about 60% of the fat in most cheeses. While not all saturated fats lead to a heightened risk of heart disease, a high intake may raise LDL (bad) cholesterol levels, which can, in turn, increase the risk of atherosclerosis. Atherosclerosis is a condition characterised by narrowed arteries due to plaque buildup, which can cause heart attacks and strokes.
However, it is important to note that the link between saturated fat and heart disease risk is complex. Some studies have found that consuming full-fat cheese may even reduce total cholesterol and LDL cholesterol levels, bringing them into a healthy range.
In addition to the type of saturated fat, individual factors such as overall diet, lifestyle, and genetic predispositions can also influence the impact of saturated fat intake on heart health. For this reason, it is always advisable to consult with a healthcare professional or registered nutritionist for personalised dietary recommendations.
The high saturated fat content in cheese slices may be of particular concern for individuals with high cholesterol or a family history of heart disease. While cheese can be enjoyed as part of a balanced diet, it is important to practise moderation and be mindful of the overall dietary intake of saturated fats.
While cheese slices can contribute to a healthy diet when consumed in moderation, it is important to be mindful of their high saturated fat content and its potential impact on heart health. For those concerned about their saturated fat intake, there are alternative options available, such as choosing low-fat or fat-free dairy products or opting for plant-based cheese alternatives.

High sodium content
Cheese slices, particularly processed cheese slices, are often criticized for their high sodium content. While sodium is an essential nutrient, helping the body maintain fluid balance and supporting nerve and muscle function, excessive sodium intake can have negative health consequences.
The recommended daily sodium intake is 2,300 mg or less, with an ideal limit of 1,500 mg. However, a single slice of processed cheese can contain up to 400 mg of sodium, contributing a significant 20% of the recommended daily amount. This high sodium content becomes problematic when considering the potential impact on cardiovascular health.
High sodium intake is linked to an increased risk of hypertension or high blood pressure. This is because sodium affects the body's fluid balance, leading to water retention and increased blood volume. As a result, the heart has to work harder to pump blood throughout the body, raising blood pressure. Over time, this can contribute to cardiovascular disease, including atherosclerosis, which is characterized by a narrowing of the arteries due to plaque buildup.
The high sodium content in cheese slices is primarily due to the addition of salt during the cheese-making process. Processed cheese, in particular, often contains added salt to enhance flavor, improve texture, and increase shelf life. This makes it important for consumers to be mindful of their cheese intake and opt for lower-sodium varieties when possible.
In summary, while cheese slices can be enjoyed as part of a balanced diet, their high sodium content is a concern. Excessive sodium intake contributes to cardiovascular health risks, and the presence of salt as an additive in processed cheese highlights the importance of moderation and informed food choices.

High calorie content
Cheese slices are considered unhealthy due to their high calorie content. Cheese is a calorie-dense food, with each ounce containing around 100 calories. For example, a 1-ounce slice of cheddar cheese has about 115 calories. The high-calorie content of cheese slices is attributed to their high-fat composition, particularly saturated fat.
Saturated fat has been associated with an increased risk of heart disease. Cheese slices, such as American cheese, typically contain high levels of saturated fat, which can contribute to elevated cholesterol levels and an increased risk of heart attacks and strokes. However, it is important to note that not all saturated fats are equal, and the type of saturated fat found in cheese may not lead to a heightened risk of heart disease.
In addition to saturated fat, cheese slices can also be high in cholesterol and sodium, further contributing to their high-calorie content. A single slice of American cheese provides 20% of the recommended daily amount of sodium, which has been linked to an increased risk of hypertension and heart disease.
While cheese slices are high in calories, they also provide essential nutrients such as protein, vitamins, and minerals. These include vitamins A and D, phosphorus, calcium, and zinc. Calcium, for example, is important for bone health and may help protect against obesity, high blood pressure, and type 2 diabetes. Therefore, while cheese slices are high in calories, they can offer some nutritional benefits when consumed in moderation.

Low nutritional value
Cheese slices, particularly processed cheese slices, have been criticized for their low nutritional value. While cheese is a rich source of calcium, protein, vitamins, and minerals, processed cheese slices often contain additional ingredients that may reduce their nutritional benefits.
Processed cheese slices are typically made with only about 50% real cheese, with the remaining ingredients being non-cheese additives. These additives can include salt, food dyes, preservatives, extra dairy, emulsifiers, and other artificial ingredients. The purpose of these additives is to enhance the texture, flavour, and shelf life of the product. However, this also means that processed cheese slices may have a less diverse flavour profile compared to natural, artisanal cheeses.
The high content of additives and low proportion of real cheese in processed cheese slices can result in a less nutritious product. For example, while natural cheeses like Swiss, Cheddar, cottage cheese, Gouda, Edam, and Gruyère may contain probiotics that support gut health, processed cheese slices may not offer the same benefits due to the presence of preservatives and other additives.
In addition, the processing of cheese can alter its nutritional profile. For instance, the heating and melting of cheese during processing can affect the structure and functionality of potential probiotics. As a result, the nutritional value of processed cheese slices may be lower than that of natural, unprocessed cheeses.
Furthermore, the high content of additives in processed cheese slices can have negative health impacts. The preservatives, emulsifiers, and artificial colours in processed cheese have been linked to an increased risk of cardiovascular disease, weight gain, and digestive issues. Therefore, the consumption of processed cheese slices with their high additive content may have adverse effects on overall health and nutrition.

Highly processed
Cheese slices, such as American cheese, are highly processed and often loaded with preservatives, additives, emulsifiers, artificial colours, and unhealthy fats. While the exact amount of cheese counted as a slice varies, a single slice can contain as much as 400 mg of sodium, which is 20% of the recommended daily intake. High sodium intake is linked to an increased risk of hypertension and high blood pressure. Cheese slices are also calorie-dense, with around 100 calories per ounce, and high in saturated fat, which can lead to elevated LDL ("bad") cholesterol levels and an increased risk of heart disease and stroke.
Processed cheese is not 100% cheese and typically hovers around 50% cheese, with the remaining ingredients being non-cheese additives. These additives are used to make the cheese creamier, more consistent in flavour, and more craveable. While natural cheese has health benefits, such as being a good source of calcium, protein, vitamins, and minerals, the processing and additives in cheese slices can make them unhealthy.
The long shelf life of processed cheese is due to the high amounts of preservatives and additives, and this processing can also strip away the nutritional value of cheese, leaving only preservatives, additives, and unhealthy fats. This highly processed nature can make cheese slices a filler product with little nutritional benefit.
However, it is important to note that the health effects of cheese slices may depend on individual factors, such as lactose intolerance or sodium sensitivity, and the specific brand and variety of cheese slice. Overall, while cheese slices can be enjoyed in moderation, they may not be the healthiest option due to their high levels of processing and associated health risks.
