1. Match the portion Check the serving size and servings per container. Compare calories and nutrients to the amount you expect to eat, not only one serving. When comparing products, use a similar portion or serving size.
2. Read the Nutrition Facts panel Note calories, protein, carbohydrates, and fat in context of your meal or day. Check nutrients you personally monitor, such as saturated fat, sodium, added sugars, or fiber. Compare like with like: similar product type, serving size, and preparation method.
3. Read the ingredients and allergen statement Read the ingredient list from the package currently in your hand. Check the manufacturer allergen statement and any preparation or storage instructions. For an allergy, medical condition, medication, pregnancy, or individual diet need, use manufacturer information and qualified guidance rather than an app score alone.
4. Save a useful comparison Save the product name, package photo, or scan if you want to compare it later. Use an ingredient scanner as a reading aid, then verify the current package details yourself. Choose based on your priorities rather than treating one label number as a complete health verdict.
