The Anatomy of a Nutrition Label
In India, the Food Safety and Standards Authority of India (FSSAI) mandates that most pre-packaged foods display a nutrition information panel. This table is your guide to what's inside, legally required to list values for energy (calories), protein,
total carbohydrates (including sugars), total fat, saturated fat, trans fat, and sodium. The purpose is to help you make informed choices by providing a snapshot of the food's nutritional properties. Before you even look at the numbers, checking for a valid FSSAI license number confirms the product is registered with the national food regulator, a baseline for safety and accountability.
What is a 'Serving Size'?
The single most important, and often most misleading, number on a label is the serving size. FSSAI defines a 'serving' as the amount of food customarily consumed in one sitting. However, the critical detail is that manufacturers often determine this serving size themselves. It is not necessarily a recommendation of how much you should eat, but rather the reference amount for all the other nutrient values listed. A packet of biscuits might list a serving size as two or three biscuits, even if most people would eat the entire row. This discrepancy is where the confusion begins.
The Per-Serving vs. Per-100g Trap
FSSAI regulations require nutritional information to be provided per 100g or 100ml, which serves as a standard for comparison. Many labels will also provide a 'per serving' column, which is where perception can be skewed. A product might seem low in sugar or high in protein per serving, but that serving may be unrealistically small. For example, a claim of "10g of protein per serving" is meaningless without context. If the serving size is large, the protein concentration could be quite low. Conversely, a tiny serving size can make a product seem healthier than it is when consumed in realistic quantities. The only way to fairly compare two different products is to use the 'per 100g' values.
Doing the Protein Math
Let's put this into practice. Imagine a snack bar that boasts "8g of protein" on the front. You flip it over and see the serving size is just 30g, and the protein listed is indeed 8g per serving. Now, consider a seemingly less 'healthy' option, like a packet of roasted chana, which might not have a splashy protein claim. Its label says it has 20g of protein per 100g. To compare, you need to normalise the snack bar's protein content. You can do this with a simple formula: (Protein per serving / Serving size in grams) x 100. For the snack bar, that's (8g / 30g) x 100, which equals approximately 26.7g of protein per 100g. In this case, the snack bar is more protein-dense. This simple calculation allows you to see past the marketing claims and understand the true nutritional value, helping you compare products on a level playing field.
Beyond the Grams: Other Label Tricks
Serving size manipulation is just one tool in the food marketing playbook. Some products, like breakfast cereals or pancake mixes, may display a protein value that is only achieved 'as prepared'—meaning it includes the milk you are expected to add at home. Another tactic involves 'protein quality'. The total grams of protein on a label don't tell the whole story about how much your body can actually use. Some protein sources, like collagen, lack certain essential amino acids but are still counted in the total protein gram count on the label. While these details are more complex, the first and most powerful step is always to check the serving size and do the math.
Your 3-Step Guide to Smarter Choices
Navigating the supermarket aisle doesn't have to be complicated. To become a more discerning consumer, follow these three steps. First, ignore the claims on the front of the package initially and turn straight to the nutrition information panel on the back. Second, find the 'per 100g' column; this is your baseline for comparing any product. Finally, look at the serving size and ask yourself if it reflects how much you would actually eat. If you're likely to eat more than one serving, multiply the calories, sugar, and protein accordingly to understand your true intake.
