The Difference Between Serving and Portion
First, let's clear up a common confusion: serving size is not the same as portion size. A 'serving size' is a standardised, measured amount of food determined by manufacturers, as guided by regulators like the Food Safety and Standards Authority of India
(FSSAI). You'll find it at the top of the nutrition facts panel. A 'portion size', however, is the amount you actually choose to eat. The serving size on a label is a reference, not necessarily a recommendation of how much you should eat. The problem is, the amount people typically eat in one sitting is often much larger than the manufacturer's stated serving size.
The 'Per Serving' Health Halo
Manufacturers often use small serving sizes to make a product appear healthier than it is. A packet of biscuits might list the nutrition for just two biscuits, or a large bottle of a sweet beverage might be listed as containing 2.5 servings. When you see a low number for calories, sugar, or fat, it creates a 'health halo', making you feel less guilty about consuming it. This tactic is not technically false, but it can be misleading because it rarely reflects real-world eating habits. Who opens a packet of snacks intending to eat only a handful and save the rest for later?
How to Calculate the Real Numbers
To get a true picture of what you're consuming, you have to do a little maths. It's the quickest way to see past the marketing. First, look for the 'servings per container' listed on the label. Then, multiply all the nutrient values—calories, fat, sugar, sodium—by the number of servings in the package if you plan to eat the whole thing. For example, if a snack has 150 calories per serving and the package contains 3 servings, finishing the bag means you've consumed 450 calories, not 150. This simple calculation applies to everything on the label, from fat to sodium, and is critical for managing your intake.
Look at the 'Per 100g' Column
An even better way to compare different products is to ignore the 'per serving' column altogether and focus on the 'per 100g' information. FSSAI regulations require that nutritional values be displayed per 100g or 100ml. This provides a standardised measure that allows for a fair, apples-to-apples comparison between two different brands or products, as the 'per serving' amount can be chosen by the manufacturer and vary wildly. A snack might seem lower in sugar than a competitor's simply because its declared serving size is smaller. The 'per 100g' column cuts through that confusion.
Beyond Calories: Check the Ingredients
The serving size also affects your perception of other ingredients. Ingredients on a food label are listed in descending order by weight. If sugar, refined flour (maida), or palm oil are in the first three ingredients, the product is primarily made of those things, no matter what health claims are on the front. Companies sometimes use multiple types of sugar (like sucrose, dextrose, or high-fructose corn syrup) so that no single one appears at the top of the list. Understanding this, along with the true serving size, gives you a much clearer idea of the snack's actual nutritional profile.
