The front sells the food. The nutrition panel and ingredient list tell you what you are buying.
Start with the denominator
Check serving size and whether the panel is per serving or per 100 g. Comparisons only work when the denominator matches. A small listed serving can make every number look artificially modest.
Read for your decision
For a protein food, check protein. For bread or cereal, fibre may matter more. For a sauce, sodium can dominate. There is no need to judge every product by every nutrient.
Use ingredients for context
Ingredients appear by weight. The list helps identify added sugars, oils and allergens, but a long list does not automatically make a food unhealthy.
Compare products on the same basis
First check whether the serving shown resembles the amount you actually eat. Then compare products per 100 grams or per 100 millilitres when serving sizes differ. Calories alone cannot describe quality: protein, fibre, saturated fat, sodium and the ingredient list answer different questions.
Front-of-pack language such as “natural”, “high protein” or “no added sugar” should trigger a closer look, not an automatic verdict. A claim may be technically valid while the product remains high in calories or sodium. Allergens, fortification and preparation instructions can also matter more than the headline number.
Practical summary
- Compare like with like using per-100-g values.
- Check how many listed servings you actually eat.
- Ignore unsupported front-of-pack words such as “fit” or “natural”.
- Convert your real portion before logging.
- Compare like-for-like weights, not marketing servings.
Frequently asked questions
Is fewer ingredients always better?
No. Fortified foods and mixed recipes can have long lists; context matters.
What does “no added sugar” mean?
No sugar was added, but naturally occurring sugar may still be present.
Should I avoid all high-sodium foods?
Overall pattern and portion matter. People with specific medical advice should follow it.
