Decoding Food Packaging: How to Read Nutritional Labels, FSSAI Marks, and Expiry Dates
Isha Malhotra (Certified Dietitian) August 19, 2026 5 min read Fact-Checked Guide
Look past deceptive marketing buzzwords to decipher ingredient hierarchy, hidden sodium, trans fats, and the critical distinction between best before and expiry dates.

Supermarket aisles overflow with glossy packaging proclaiming bold slogans like "100% Natural", "Heart Healthy", and "Zero Cholesterol". However, turning the box around to inspect the fine print frequently reveals a strikingly different nutritional reality.

Essential Checkpoints on Every Package

1. The 14-Digit FSSAI License Number

Every legally marketed packaged food in the country must display a valid 14-digit license number alongside the official regulatory logo. Consumers can verify registration authenticity instantly via the official national food safety consumer portal.

2. Ingredient Order Reflects Proportional Weight

By statutory requirement, ingredients are listed in descending order by weight. If a box labeled "Whole Wheat Biscuits" lists refined wheat flour (maida) and sugar as its first two ingredients, it is predominantly a junk snack, not a whole grain staple.

3. "Best Before" vs. "Use By / Expiry"

"Best Before" denotes the window of optimum flavor, crispness, and aroma. In contrast, "Expiry Date" marks a firm biological safety cutoff, after which the item may harbor bacterial pathogens or degraded chemical preservatives.
