What should I check first on a label?
Check the serving basis and ingredient list first. Then compare the nutrients that matter to your situation using the same basis for both products. Do not compare one product’s tiny serving with another product’s larger serving and assume the lower number means a better choice.
Step 1: compare like with like
Use values per 100 grams, per 100 millilitres or matching portions where available. Compare two yoghurts or two breads, rather than unrelated foods. Think about how much you actually use and whether it forms a meal, a snack or an occasional extra.
Compare two lunch yoghurts
Check that the panels use the same basis, then compare ingredients, added sugars where listed, protein and any features important to your needs. Consider the portion you actually plan to eat and the rest of lunch. A single lower number cannot tell you whether the yoghurt is a better overall choice. Allergy suitability, affordability and enjoyment can settle the decision once the information is clear.
Step 2: ignore the halo
Words such as natural, fitness or premium do not explain the overall nutritional profile. A product can highlight one appealing ingredient while containing other things you want to consider. Look at ingredients, fibre, sugars, salt and fats in context, rather than relying on the front label.
Step 3: choose something you will eat
A technically impressive product that you dislike or cannot afford is a poor everyday choice. Decide what matters most for this purchase: convenience, fibre, allergy suitability or taste, for example. Check allergy warnings carefully, and use professional advice for medical diets.

Questions readers ask
Is the shortest ingredient list always best?
No. A short list is not a complete quality measure. Nutritional suitability, food safety and your actual needs matter.
Do I have to compare every nutrient?
No. Choose a few relevant features for similar products and use the same serving basis. Keep shopping manageable.
