Macronutrient breakdown: 40% carbs, 48% fat, 12% protein
A Tesco cheese and onion roll contains 173 calories, with a macronutrient breakdown of 40% carbohydrates, 48% fat, and 12% protein. This equates to 288 calories per 100g, which is considered a relatively high-calorie density.
To understand this macronutrient composition, it is important to know that carbohydrates and proteins each contribute 4 calories per gram, while fat contributes 9 calories per gram. Therefore, in a cheese and onion roll, 40% of the 173 calories come from carbohydrates, 48% from fat, and 12% from protein. This roughly translates to 69.2 calories from carbohydrates, 83.04 calories from fat, and 20.76 calories from protein.
The 40-30-30 diet, which recommends consuming 40% of your calories from carbohydrates, 30% from protein, and 30% from fat, is a popular approach. This diet is geared towards muscle gain and may not be suitable for those with liver or kidney issues or those training for endurance exercises. However, it's important to note that there is no one-size-fits-all diet, and individual needs and preferences vary.
For athletes and those engaging in endurance exercises, a different macronutrient breakdown may be more suitable, such as 51% carbohydrates, 18% protein, and 33% fat. Similarly, a vegetarian diet may have different macronutrient ranges, typically with a higher percentage of carbohydrates and a lower percentage of protein and fat.
It is always recommended to consult a registered dietitian if you need help determining the right macronutrient breakdown and dietary plan for your specific needs and goals.

Calorie density: 288 calories per 100g
A cheese and onion roll from Tesco contains 173 calories, with a calorie density of 288 calories per 100g. This means that approximately 67% of the roll's weight constitutes calories. To put this in context, an Aldi onion roll contains 190 calories, suggesting that the addition of cheese adds a significant caloric density to the product.
Calorie density is an important consideration when evaluating food products, as it provides insight into the energy density of a particular food item. In the case of the Tesco cheese and onion roll, the calorie density indicates that a considerable portion of the roll's weight is attributed to calories. This can be useful for individuals monitoring their calorie intake, as it allows for a more precise understanding of the caloric impact of consuming a given weight of the product.
The calorie density of 288 calories per 100g suggests that the Tesco cheese and onion roll is a relatively energy-dense food item. This is further supported by comparing it to other similar products, such as the Aldi onion roll, which has a higher total calorie count but a lower calorie density. The addition of cheese increases the calorie density, likely due to the fat and protein content contributed by the cheese.
It is worth noting that the calorie density and total calorie count of a food product are separate but related concepts. Calorie density refers to the number of calories per gram of the product, while the total calorie count simply represents the aggregate amount of calories in the entire product. In the case of the Tesco cheese and onion roll, both the calorie density and the total calorie count are relatively high, indicating a substantial caloric contribution per gram of the product consumed.
Understanding the calorie density of foods can be particularly useful for individuals aiming to manage their weight or monitor their calorie intake. For those seeking to increase their calorie consumption, choosing foods with higher calorie densities can be advantageous, as it allows for a more efficient caloric intake relative to the volume of food consumed. Conversely, for individuals aiming to reduce their calorie intake, opting for lower-calorie-density foods can help promote satiety while minimizing caloric impact.
In summary, the Tesco cheese and onion roll's calorie density of 288 calories per 100g indicates a relatively high caloric contribution per gram of the product. This information can be valuable for informed dietary choices, particularly for those mindful of their calorie intake or seeking to understand the caloric composition of specific food items.
