The Serving Size Illusion
Food packaging can often be misleading. A common tactic involves using unrealistically small serving sizes to make a product appear healthier than it is. For example, a packet of chips might list the calories and fat for a serving of just 10 chips, but
most people consume a much larger portion in one sitting. This discrepancy between the labelled 'serving size' and the actual 'portion size' (the amount you eat) can lead to unintentional overconsumption of sugar, salt, and fat. A sugary cereal might boast only 8 grams of sugar per serving, but if your bowl holds three times that amount, you're starting your day with a 24-gram sugar hit without even realising it. Manufacturers are aware of this and can frame nutritional information to their advantage, making a product seem more appealing to health-conscious consumers.
Your Secret Weapon: The 100-Gram Rule
To cut through the confusion, there is a simple and powerful tool at your disposal: the per-100-gram (or per-100ml) column on the nutritional information panel. In India, the Food Safety and Standards Authority of India (FSSAI) mandates that nutritional information for energy, protein, carbohydrates, fats, and sodium be declared per 100g or 100ml. This creates a standardised baseline, allowing for a direct, apples-to-apples comparison between different products, regardless of their packet size or suggested serving size. By using this metric, you can accurately assess which product is genuinely lower in sugar, salt, or saturated fat, empowering you to make a truly informed choice.
How to Compare Foods Like a Pro
Putting this into practice is straightforward. When you're comparing two products, ignore the 'per serving' information at first. Instead, find the 'per 100g' column on both labels. Then, focus on the nutrients that matter most to you. For a quick health check, pay attention to sugar, saturated fat, and sodium (salt). For example, Biscuit Brand A might list 5g of sugar per serving of 20g, while Biscuit Brand B lists 8g of sugar per serving of 30g. On the surface, Brand A looks better. But when you check the per-100g values, you might find Brand A contains 25g of sugar per 100g (5g x 5), while Brand B contains roughly 26.7g of sugar per 100g (8g x 3.33). The difference suddenly becomes much clearer, and you might find other products are significantly lower. A general rule of thumb is to be cautious of savoury foods with over 10g of sugar per 100g, or any food with over 15g of sugar per 100g.
Where This Trick Matters Most
This comparison method is especially useful in certain supermarket aisles where serving sizes can be particularly deceptive. Breakfast cereals are a classic example, with wildly varying serving suggestions. Juices and sweetened beverages are another category where comparing sugar content per 100ml reveals the true story behind 'no added sugar' claims that might still be high in natural sugars from fruit concentrates. When it comes to snacks like biscuits, chips, and instant noodles, the per-100g values for sodium and fat can be eye-opening. What seems like a small snack can contribute a significant portion of your recommended daily intake for salt and unhealthy fats once you standardise the measurement. Even ready-to-eat meals and sauces benefit from this check, uncovering hidden sugars and salt.
Beyond the Numbers
While the 100-gram comparison is an invaluable tool for navigating the world of packaged foods, it's also important to remember the bigger picture of nutrition. The quality of ingredients matters just as much as the numbers. A label might show low sugar, but the product could be filled with artificial sweeteners or refined flours. Always take a moment to read the ingredients list, which is presented in descending order of weight. Choosing products with whole, recognisable ingredients is always a good strategy. The 100-gram rule helps you make better choices among processed options, but the foundation of a healthy diet remains a variety of whole foods like fresh fruits, vegetables, and lean proteins.
