What You'll Learn
Processed cheese is not 100% cheese
The addition of these ingredients significantly changes the flavour and texture of the cheese. They are added to make the cheese creamier, more consistent in flavour, and more craveable. While processed cheese is fine to consume in moderation, it is not the healthiest option. The production process means that real cheese has flavour possibilities that processed cheese cannot replicate.
Processed cheese is often laden with additives, which can make it so that the product does not even need to be refrigerated. In fact, some people argue that it is not cheese at all. The first hint of this is the extremely long list of ingredients on the packaging. Many of these ingredients come with potential health risks. For example, vegetable oils in processed cheese are highly refined and oxidized, making them toxic and inflammatory.
Processed cheese products often contain alarmingly high levels of sodium, which can lead to high blood pressure and kidney strain. They may also contain added sugars and trans fats, which can be harmful. Additionally, the emulsifiers in processed cheese may disrupt gut bacteria, leading to inflammation and an increased susceptibility to diseases like inflammatory bowel disease (IBD).

High sodium content
Processed cheese is not 100% cheese. It usually hovers around 50% cheese, with the remaining ingredients being non-cheese additives like salt, food dyes, preservatives, extra dairy, emulsifiers, and other artificial ingredients. These additives are added to melted, pasteurized cheese, which is then converted into slices, sauces, or spreads.
One of the key reasons processed cheese products are unhealthy is their high sodium content. Salt is added to enhance flavor and act as a preservative. A single slice of processed cheese can contain up to 300 mg of sodium, which is nearly 15% of the daily recommended intake. Excessive sodium intake can lead to several health issues:
High Blood Pressure: Excessive salt increases water retention, which raises blood pressure and puts strain on the heart. This can lead to hypertension and increase the risk of heart disease.
Kidney Problems: High sodium levels force the kidneys to work harder to filter blood, which can lead to kidney strain and, over time, kidney disease or damage. Certain additives in processed cheese, such as potassium phosphate, may also contribute to kidney issues.
Increased Risk of Disease: High sodium intake can promote inflammation in the body, which has been linked to chronic conditions like heart disease, diabetes, and certain cancers.
Nutritional Concerns: Processed cheese may be marketed as a good source of calcium and a way to get your daily dairy servings. However, the high sodium content and other additives may outweigh any nutritional benefits. The presence of artificial vitamins, for example, may even be toxic as they cannot be properly absorbed by the body.
While processed cheese is convenient and tasty, it's important to consume it in moderation due to its high sodium content and potential health risks. It's always a good idea to check nutrition labels and vary your cheese choices to maintain a balanced diet.

Vegetable oils are inflammatory
Processed cheese slices are a convenient and tasty addition to many meals, but they are not without their drawbacks. While it is fine to consume processed cheese in moderation, it is not the healthiest option. One of the key reasons is the high sodium content. Salt is added as a flavour enhancer and preservative, but it can lead to high blood pressure and put a strain on the heart. For example, a single slice of processed cheese can contain up to 300 mg of sodium, which is a significant proportion of the daily recommended intake. Certain processed cheese products, such as Cheez Whiz and Velveeta, have alarmingly high sodium levels, with Cheez Whiz containing over 1.6 grams per 100 grams.
In addition to high sodium levels, processed cheese slices often contain vegetable oils, which are highly inflammatory. Vegetable oils are highly refined and oxidized, rendering them toxic and promoting inflammation in the body. These oils are full of fats that can clog arteries and contribute to obesity. Hydrogenated vegetable oils, in particular, are best avoided due to their high trans-fat content. Regular consumption of trans fats has been deemed harmful, and many countries have banned them.
The production process of processed cheese involves adding various non-cheese ingredients to melted, pasteurized cheese, which significantly alters the flavour and texture. These extra ingredients can include preservatives, emulsifiers, artificial colouring agents, and other artificial additives. While some of these additives are not inherently harmful, such as MSG, which is safe in moderation, others may have negative effects. For example, artificial colourings like Yellow 6 and tartrazine are banned in the European Union due to their potential to promote tumour growth.
Overall, while processed cheese slices are convenient and can be enjoyed in moderation, they are not the healthiest option due to their high sodium content, inflammatory vegetable oils, and various additives. These additives can have negative effects on health, including promoting inflammation, disrupting gut bacteria, and increasing the risk of chronic conditions such as heart disease, diabetes, and certain cancers.

Artificial ingredients
Processed cheese is not 100% cheese. It usually hovers around 50% cheese, with the remaining ingredients being non-cheese additives. These additives are added to melted, pasteurized cheese, altering the texture and flavour of the original cheese.
Some of the artificial ingredients commonly found in processed cheese include:
- Emulsifiers: These are added to blend fats and water in processed cheese. Research suggests that emulsifiers may negatively impact gut bacteria, leading to inflammation and an increased risk of inflammatory bowel disease (IBD). An example of an emulsifier used in processed cheese is trisodium phosphate, which is also used in cleaners and stain removers.
- Preservatives: These are added to enhance the shelf life of the product. Sodium phosphate, for instance, helps maintain the cheese's smooth texture, but excessive intake has been linked to kidney damage and imbalanced calcium levels.
- Artificial colouring agents: Agents like Yellow 6 and Yellow tartrazine are added for visual appeal. These colourings are banned in the European Union as they have been shown to promote tumour growth in animal studies. They can also trigger allergic reactions or hyperactivity in sensitive individuals, especially children.
- Vegetable oils: Vegetable oils used in processed cheese are often highly refined and oxidized, making them toxic and inflammatory. These oils are associated with increased risk of obesity and clogged arteries.
- Isolated vitamins: While it may seem beneficial to have vitamins in cheese products, these isolated forms cannot be properly absorbed by the body and may even be toxic.
- Monosodium glutamate (MSG): MSG is sometimes added to enhance flavour. While it is not harmful in moderation, sensitive individuals may experience headaches, nausea, or chest tightness.
The addition of these artificial ingredients significantly alters the nutritional profile of the cheese, often resulting in high sodium and fat levels. As such, while processed cheese may be convenient and tasty, it is important to consume it in moderation as part of a balanced diet.

High cholesterol levels
Processed cheese slices are typically high in cholesterol and saturated fat. While cheese can be a part of a healthy, well-balanced diet, the specific cheeses chosen and the amount consumed are important considerations.
Cheese is a significant source of cholesterol-raising fat in the American diet, according to the National Cancer Institute. However, research on the link between dietary cholesterol and blood cholesterol levels has produced mixed results. While cheese contains cholesterol, recent studies indicate that the cholesterol we eat may not significantly impact blood cholesterol levels. Instead, other factors, such as genetics, lifestyle, and the intake of other nutrients like saturated fat, play a more significant role in raising blood cholesterol levels.
Saturated fat, found in cheese and other dairy products, can increase low-density lipoprotein (LDL) cholesterol, also known as the "bad" cholesterol. When there is too much LDL cholesterol in the bloodstream, it can adhere to artery walls, forming plaques. This build-up of cholesterol can lead to clogged arteries, high blood pressure, and an increased risk of heart attack and other cardiovascular issues. Therefore, it is crucial to monitor saturated fat intake when managing high cholesterol levels.
To maintain healthy cholesterol levels while including cheese in your diet, consider the following suggestions:
- Opt for low-fat or reduced-fat cheeses: These varieties have significantly lower saturated fat and cholesterol content than their whole-milk counterparts. Examples include low-fat or nonfat versions of cheddar, Swiss, cottage cheese, ricotta, and mozzarella.
- Monitor portion sizes: Keep portions small and weigh them to ensure you stay within a healthy range. A single 1-ounce (28-gram) slice of cheddar cheese, for instance, contains about 6 grams of saturated fat, which is roughly half of the recommended daily limit.
- Choose vegan cheese alternatives: Vegan cheeses, made from plant products like soy or nuts, lack the saturated fat found in full-fat dairy products.
- Consult a healthcare professional: Before making significant dietary changes, speak with your doctor or a registered dietitian nutritionist. They can provide personalized recommendations based on your health history and nutrient needs.
