Eggs, milk, and cheese are commonly consumed food products, but are they bad for you? They are rich in protein and provide essential nutrients. However, some studies suggest that diets high in animal protein may increase the risk of certain health issues. For example, a controversial study found that high levels of dietary animal protein were linked to an increased risk of death from cancer or diabetes in people under 65 years of age. Additionally, eggs, milk, and cheese can contribute to high cholesterol levels due to their saturated fat content. On the other hand, grass-fed cheese may provide a healthier balance of fatty acids, and cheese consumption has been linked to improved dental health in children. While eggs, milk, and cheese can be part of a healthy diet, moderation is key, and simple substitutions, such as choosing low-fat dairy products, can help reduce potential negative impacts on health.

What You'll Learn
Eggs, milk, and cheese can increase cholesterol levels
Eggs, milk, and cheese are nutrient-dense foods that can be part of a healthy diet. However, they contain saturated fats, which can increase cholesterol levels in the body. High cholesterol is a risk factor for cardiovascular disease and other health issues. Thus, while not necessarily bad, the consumption of eggs, milk, and cheese should be moderated, especially for those with high cholesterol.
Eggs, milk, and cheese are significant sources of saturated fat, which is known to contribute to high cholesterol levels. While the body needs some cholesterol for essential functions, excessive amounts can lead to health problems. High cholesterol can increase the risk of cardiovascular disease, heart attacks, and strokes. Therefore, it is essential to manage cholesterol levels through a balanced diet and, if necessary, medication.
Eggs, in particular, are high in cholesterol, with one large egg containing around 186 mg of cholesterol. However, the effect of egg consumption on blood cholesterol levels is complex and varies between individuals. Some studies suggest that eating up to one egg per day may not significantly impact cholesterol levels for most people. Nevertheless, those with high cholesterol or cardiovascular disease may need to limit their egg intake.
Milk and cheese are also sources of saturated fat and cholesterol. Whole milk and full-fat cheeses tend to have higher saturated fat content, so switching to low-fat or reduced-fat options can help lower cholesterol intake. Additionally, grass-fed dairy products may provide a healthier balance of omega-6 and omega-3 fatty acids, which can benefit heart and metabolic health.
While eggs, milk, and cheese can increase cholesterol levels, it is important to note that they can still be part of a balanced diet. Simple substitutions, such as choosing lean meats and low-fat dairy products, can help manage cholesterol intake. Additionally, other nutrients in these foods may offer health benefits. For example, cheese is a good source of calcium and phosphorus, essential for bone health, and eggs provide high-quality protein and various vitamins and minerals.
In conclusion, while eggs, milk, and cheese can increase cholesterol levels, they do not need to be completely eliminated from the diet. Moderation and simple substitutions can help maintain a healthy cholesterol balance while still enjoying these nutrient-rich foods. For personalized advice, it is always recommended to consult with a healthcare professional or registered dietitian.

High consumption of these foods may be as harmful as smoking
While eggs, milk, and cheese are nutritious foods, their high consumption may have adverse health effects. These foods are rich in saturated fats, contributing to high cholesterol levels. While cholesterol is essential for the body, excessive amounts can lead to health issues. High cholesterol is associated with an increased risk of cardiovascular disease and other complications.
Eggs, in particular, have been the subject of controversy regarding their impact on health. Some studies suggest that egg yolks can contribute to carotid plaque build-up, similar to the effects of smoking. However, it is important to note that eggs also contain beneficial nutrients such as unsaturated fats and omega-3 fatty acids, which may help prevent cardiovascular disease. The American Heart Association recommends limiting daily cholesterol intake to 300 milligrams, while a single egg yolk contains about 185 milligrams of cholesterol. Thus, it is advisable to limit egg consumption to one egg per day.
Similarly, high consumption of milk and cheese, which are significant sources of animal protein, has been linked to increased mortality rates, particularly during middle age. A study published in Cell Metabolism found that middle-aged people who consumed large amounts of animal protein, including milk and cheese, were 74% more likely to die within the study period than those with lower protein intake. The increased mortality risk was attributed to a rise in cancer cases, with a strong correlation found between high-protein diets and cancer.
The findings suggest that excessive protein consumption, especially from animal sources, can be as detrimental to health as smoking. The recommended daily protein intake for middle-aged adults is about 0.8 grams of protein per kilogram of body weight. However, it is important to note that moderate protein intake is beneficial for individuals over the age of 65. While it is not necessary to eliminate these foods entirely, making simple substitutions, such as choosing low-fat dairy products, can help maintain a healthier diet.

Cheese is worse for the environment than eggs
While eggs, meat, and dairy can contribute to high cholesterol levels, they are not necessarily bad for health. According to some nutrition experts, a diet rich in meat, eggs, and dairy could be harmful to health, whereas others argue that they can be consumed in moderation as part of a healthy diet. However, this discussion focuses on the environmental impact of cheese and eggs.
Cheese is significantly worse for the environment than eggs. Firstly, cows produce methane, a greenhouse gas with a global warming potential 265-298 times greater than carbon dioxide. Additionally, dairy farming is a major source of nitrous oxide, another potent greenhouse gas. Cheese also requires a lot of milk, and dairy cows consume large amounts of feed and antibiotics, contributing to environmental harm.
Eggs, on the other hand, are considered environmentally friendly. Chickens require fewer resources and can be kept in small spaces, producing minimal negative outputs. They can also be easily sourced locally, reducing transportation costs and environmental impact.
The environmental impact of the dairy industry is further exacerbated by the intensive farming methods used to maximize profits. Cows are often kept in cramped conditions and fed high-yield feed instead of grass, requiring additional land and resources.
Overall, while eggs and cheese may be part of a healthy diet in moderation, cheese has a significantly higher environmental impact than eggs due to the intensive farming practices and greenhouse gas emissions associated with dairy production.

Cheese is high in calories, saturated fat, and salt
Cheese is a great source of protein and calcium. However, it is often high in calories, saturated fat, and salt. For instance, a 30g portion of cheddar cheese provides seven per cent of your daily calories, and there can be more salt in this portion than in a packet of crisps. Moreover, around 23% of the average American's daily intake of saturated fat comes from cheese.
Goat's cheese, for example, contains about 26g of fat per 100g, which is similar to the fat content of Brie and Edam. Roquefort, halloumi, feta, and cheese singles are even saltier than seawater. Feta, which is often packaged in brine, can be high in sodium. However, feta is typically lower in calories than other cheeses.
If you are concerned about your saturated fat and salt intake, you can opt for low-fat cheeses such as mozzarella, feta, cottage cheese, and ricotta. These cheeses are lower in fat than cheddar, American cheese, and goat's cheese. You can also try vegan cheese, which lacks the saturated fat that full-fat dairy products contain.
While cheese is high in calories, saturated fat, and salt, it can be consumed in moderation as part of a healthy diet.

Lactose intolerance and milk allergies can make these foods bad for some people
While eggs, milk, and cheese can be nutritious, they may be harmful to some due to lactose intolerance or milk allergies. Lactose intolerance occurs when the body cannot digest lactose, a sugar found in milk, due to a lack of the enzyme lactase. This can lead to digestive issues such as gas, bloating, and diarrhea. However, lactose-intolerant individuals may still tolerate certain firm, aged cheeses, such as Parmesan, Swiss, and cheddar, as these cheeses are low in lactose. Additionally, lactase supplements may help manage symptoms, but consulting a doctor is advisable.
On the other hand, a milk allergy is an immune reaction to proteins in milk, such as casein, which can be life-threatening. People with milk allergies must avoid all foods containing dairy, including cheese. Milk allergy symptoms can vary and may appear early in life, even before the age of one. It is important to distinguish between lactose intolerance and a milk allergy, as the former is a digestive issue, while the latter is an immune response.
Eggs, milk, and cheese can also impact cardiovascular health due to their saturated fat content. High consumption of saturated fats is linked to increased low-density lipoprotein (LDL) or "bad" cholesterol, which can elevate the risk of cardiovascular diseases. However, simple substitutions, such as choosing low-fat dairy products, can help maintain a healthy cholesterol level without completely eliminating these foods from the diet.
While some studies suggest that diets high in animal protein, including eggs, milk, and cheese, may negatively impact health and increase the risk of certain diseases, the overall consensus is that these foods can be part of a healthy diet when consumed in moderation. Additionally, grass-fed cheese and dairy may provide a healthier balance of omega-3 and omega-6 fatty acids, benefiting heart and metabolic health.
