Front of pack claims are designed to catch your eye, not to tell you the truth about a product. "High protein," "natural," and "low fat" all sound appealing, but they're marketing terms with pretty loose thresholds behind them. The nutrition panel on the back is where the actual useful information lives, and learning to read it properly takes about thirty seconds once you know what to look for.

The first thing worth checking is serving size, because this is where a lot of labels quietly mislead people. A product might look impressively low in sugar or calories until you notice the serving size listed is half of what a normal person would actually eat in one sitting. Always check the "per 100g" column rather than the "per serving" column when comparing products, since manufacturers can set serving sizes wherever makes their numbers look best.

Protein content is obviously the big one for anyone training regularly, but it's worth looking past the total grams to where that protein is coming from. A product padded with collagen or gelatin can list a decent protein number while missing key essential amino acids that muscle actually needs, since collagen is an incomplete protein. Something like a whey protein isolate or a well formulated pea protein isolate will list a fuller amino acid profile, and reputable brands are usually happy to share that information if it's not on the label itself.

Added sugar is another spot worth double checking, especially on anything marketed toward athletes like recovery drinks or bars. Total sugars on a label include naturally occurring sugars from fruit or dairy, which aren't the issue, but added sugars are listed separately and are worth watching if you're trying to manage overall intake. A product can be labelled "natural" and still carry a hefty dose of added sugar, so the two claims aren't related.

Sodium matters more than most people realise, and not always in the direction you'd expect. If you're training hard and sweating heavily, some sodium is genuinely useful for hydration and performance, which is exactly why electrolyte powders are formulated with it deliberately rather than as filler. Context matters here, sodium in a processed snack food is a different situation to sodium in a product designed to replace what you lose through sweat.

The ingredient list itself is worth a quick scan too, since ingredients are listed by weight from most to least. If sugar or a vague "flavouring" blend sits near the top of the list on something marketed as a health product, that tells you more than any front of pack claim will. Shorter ingredient lists with recognisable names are usually a decent sign, though this isn't a hard rule since some genuinely useful additions like electrolytes or amino acids just have technical sounding names.

None of this requires becoming obsessive about every label at the supermarket. Spending a bit of extra time comparing the products you buy regularly, like your protein powder or your pre and post training snacks, pays off far more than agonising over every packaged item in your pantry.
