What You'll Learn
Cheese pizza contributes to your daily iron intake
While pizza is often associated with junk food and negative health impacts, it can be a surprisingly nutritious food. Cheese pizza, in particular, contributes to your daily iron intake.
Iron is an essential mineral that plays a vital role in the body's function. It is a key component of haemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Iron also helps the body use energy from food and supports the immune system. There are two forms of iron in food: haem and non-haem iron. Foods derived from animals contain both forms, while plant-based foods contain only non-haem iron.
Cheese pizza can be a good source of iron, depending on its size and the specific ingredients used. For example, two slices (approximately 1/4) of a 13-inch cheese and meat pizza provide about 18-25% of the daily recommended allowance of iron. This contribution to your iron intake is significant, especially considering that most people do not actively modify their pizza to be more nutritious.
The iron content in cheese pizza primarily comes from the cheese itself. Cheese is a dairy product that contains both haem and non-haem iron. While the amount of iron in cheese varies depending on the type and brand, it is generally a good source of this essential mineral. Additionally, if your cheese pizza includes meat toppings, you will also be consuming the iron provided by those ingredients.
While cheese pizza can contribute to your daily iron intake, it is important to remember that pizza also contains other nutrients, some of which may be less beneficial if consumed in excess. For example, cheese is a contributor of both sodium and cholesterol. However, by making conscious choices, such as using reduced-sodium cheese or adding fresh vegetable toppings, you can enhance the nutritional profile of your pizza while still enjoying its delicious taste.

Cheese is a source of sodium and cholesterol
Cheese is a beloved food, enjoyed for its rich, creamy flavour and satiating qualities. However, it is also a source of sodium and cholesterol, which can have negative health effects.
Firstly, cheese is high in sodium, which can elevate blood pressure and lead to an increased risk of heart problems. This is particularly true of certain types of cheese, such as feta, which is packaged in brine and can be very high in sodium. Other types of cheese, such as goat's cheese, whole-milk mozzarella, and Swiss cheese, are lower in sodium with only 50-100 mg per serving.
Secondly, cheese is a source of cholesterol. While the body needs some cholesterol to function, too much can lead to clogged arteries, high blood pressure, and an increased risk of heart attack and other heart conditions. The extent of the increase in cholesterol depends on the type of cheese, with low-fat and reduced-fat cheeses having a much lower cholesterol content.
In addition to being a source of sodium and cholesterol, cheese also contains beneficial nutrients such as calcium and protein, and some fermented types contain probiotics. Eating cheese may even aid weight loss and help prevent heart disease and osteoporosis.
When considering the health effects of cheese, it is important to look at the overall diet and how the cheese is being eaten. For example, eating cheese with refined grains or processed meats may negate its health benefits. Overall, it is recommended to consume cheese in moderation as part of a balanced diet.

Pizza is a good source of polyunsaturated fat
While pizza is often perceived as unhealthy, it can be a nutritious food. Two slices (1/4) of a typical 13-inch cheese and meat pizza provide almost 1/3 of the daily recommended allowance of protein, vitamins, and minerals. Pizza is also a good source of polyunsaturated fat. Vegetable oil, olive oil, and oil-based shortenings are commonly used in the crust formulation, and these are good sources of polyunsaturated fat.
Polyunsaturated fats are considered "good fats" and are known to have health benefits. Eating polyunsaturated fats in place of saturated fats lowers "bad" LDL cholesterol and improves the ratio of total cholesterol to "good" HDL cholesterol, reducing the risk of heart disease. The American Heart Association suggests that 8-10% of daily calories should come from polyunsaturated fats. There is evidence that consuming more polyunsaturated fat—up to 15% of daily calories—instead of saturated fat can further lower the risk of heart disease.
Pizza and related products such as calzones, strombolis, and breadsticks are good sources of polyunsaturated fat, with only modest cholesterol contributions from meat and cheese toppings. Pizzas are also quite high in complex carbohydrates, primarily from starches, making them a good energy food. However, pizzas tend to be low in fiber content, especially when made with regular white pizza flour. Using whole wheat or multi-grain flour can significantly improve the fiber content of pizza.
While pizza can be a good source of polyunsaturated fat, it is important to consume it in moderation as part of a balanced diet. The sodium content of pizza can also be a concern, as meat and cheese toppings are the main contributors of sodium. However, this can be addressed by using reduced-sodium cheese and choosing healthier toppings such as poultry, seafood, and fresh vegetables.

Pizzas are high in complex carbohydrates
While a cheese pizza does contain some iron—about 18-25% of the daily recommended allowance—it is not a good source of iron compared to other foods. However, pizzas are quite high in complex carbohydrates, which are mostly starches. This makes pizza a good energy food. The carbohydrate content of pizza ranges from 34% to 55% of total macronutrients, depending on the size and type of pizza.
Pizza is a popular food choice, not only for its taste but also for its nutritional value and convenience. It is a good source of polyunsaturated fat, with vegetable oil, olive oil, and oil-based shortenings commonly used in the crust formulation. In addition, the cheese and various toppings contribute to the nutritional profile of pizza.
The type of flour used in the crust can significantly impact the nutritional value of pizza. For example, using whole wheat or multi-grain flour instead of regular white pizza flour can increase the fiber content of the pizza. Additionally, the sodium content of pizza, which often comes from the cheese and certain toppings, can be reduced by using engineered cheese products made with cholesterol-free vegetable oil and lower sodium content.
Overall, pizza can be a nutritious food when consumed in moderation. It provides a good balance of carbohydrates, protein, and fat. However, it is important to be mindful of the sodium and cholesterol content, especially when choosing toppings. By making conscious choices and opting for healthier alternatives, individuals can enhance the nutritional profile of their pizza while still enjoying this beloved dish.

Iron deficiency can lead to anaemia
Iron is an essential nutrient that the body uses to produce red blood cells, which help store and carry oxygen in the blood. A lack of iron in the diet or an inability to absorb iron can lead to iron deficiency. Over time, this can lead to iron deficiency anaemia, a condition where the body doesn't have enough iron to produce red blood cells, resulting in a reduced number of red blood cells and decreased oxygen delivery to the body's organs and tissues.
Iron deficiency anaemia is the most common type of anaemia and can be caused by several factors, including heavy menstrual bleeding, pregnancy, and blood loss from conditions such as stomach ulcers, polyps, or cancer. In addition, certain intestinal disorders, such as celiac disease, can interfere with the absorption of iron from food, leading to iron deficiency anaemia.
The signs and symptoms of iron deficiency anaemia can vary in intensity and may include fatigue, headache, pallor, and shortness of breath. Initially, the symptoms may be mild or go unnoticed, but as the body becomes more deficient in iron, the symptoms can intensify. Left untreated, iron deficiency anaemia can lead to serious health complications, including heart problems such as an irregular or rapid heartbeat, heart failure, and an enlarged heart. It can also increase the risk of infections and affect growth and development in infants and children.
While iron deficiency can lead to anaemia, it is important to note that consuming too much iron can also be harmful. Excess iron accumulation can damage the liver and cause other complications. Therefore, it is essential to maintain adequate iron levels through a balanced diet or, if necessary, with appropriate iron supplementation under medical supervision.
Regarding the iron content in cheese pizza, a 13-inch cheese and meat pizza can provide 18-25% of the daily recommended allowance of iron. However, it is worth noting that the overall nutritional profile of pizza can be improved by reducing the sodium content and adding healthier toppings.
