When it comes to understanding food quantities, the terms 'serving size' and 'portion size' are often used interchangeably, yet they signify distinct concepts. Serving size refers to the recommended quantity of food, typically outlined by nutritional guidelines or packaging. It serves as a standard measure, helping consumers understand how much of a food they should ideally consume, based on a balanced diet.

In contrast, portion size refers to the amount of food an individual actually chooses to eat during a meal. This can vary significantly from one person to another and is often influenced by personal preferences, hunger levels, and social contexts. For instance, while the serving size of pasta may be 75 grams, one might serve themselves a generous 150 grams, inadvertently doubling the recommended intake.

Understanding the difference between these two terms is crucial for making informed dietary choices. By recognising both the recommended serving sizes and the typical portion sizes, individuals can better manage their food intake, leading to healthier eating habits and a balanced lifestyle.

One tablespoon of peanut butter typically contains around 90 to 100 calories, making it a rich source of energy. The calorie breakdown is predominantly from fats, which account for approximately 70% of the total caloric content. This includes both saturated and unsaturated fats, the latter being the healthier option. Additionally, a tablespoon of peanut butter contains about 4 grams of protein, contributing to its appeal as a nutritious snack. Carbohydrates make up a smaller portion, generally around 3 grams, with dietary fibre playing a role in digestive health. While peanut butter is calorie-dense, its healthy fat profile and protein content can make it a beneficial addition to a balanced diet when consumed in moderation.
