Quick answer: Read the serving size and the per-100 g or per-100 ml values before comparing packaged foods. Check energy, saturated fat, sugar, sodium and other nutrients relevant to your needs. A ‘low fat’, ‘natural’ or ‘no added sugar’ claim does not tell the whole nutritional story.
Use this guide as a practical decision aid. Start with the essentials, verify important claims independently and avoid irreversible changes until you understand the consequences.
Quick checklist
- Start with the serving size: A nutrition panel may describe one serving rather than the entire package. If a bag contains three servings, eating the whole bag can triple the listed per-serving amount.
- Compare per 100 g or 100 ml: A common reference amount makes similar products easier to compare. Use it to assess sugar, saturated fat, sodium and energy when the products serve similar purposes.
- Understand energy units: Labels may show kilocalories (kcal), kilojoules (kJ) or both. Energy matters, but it is not the only measure of a food’s nutritional quality.
- Look closely at sugar: Check total sugars and ingredients. ‘No added sugar’ does not necessarily mean the food contains no naturally occurring sugars.
- Check sodium and salt: Sodium is relevant to many dietary recommendations and can be high in sauces, processed meats, snacks and ready meals. Sodium and salt are related but not identical label terms.
- Consider saturated fat and fibre: Saturated fat is one part of evaluating foods, while fibre can support a balanced diet. Look at the whole product and its role in your meals.
- Read the ingredients and allergens: Ingredients are commonly listed in descending order by weight, subject to local labelling rules. Check for allergens and substances relevant to your dietary needs.
- Use front-of-pack labels as a shortcut, not a substitute: Singapore’s Healthier Choice Symbol and Nutri-Grade labels can help consumers make comparisons within their intended categories. They do not replace the full nutrition panel or personal dietary requirements.
Tip 1: Start with the serving size
A nutrition panel may describe one serving rather than the entire package. If a bag contains three servings, eating the whole bag can triple the listed per-serving amount.
Do not compare two products using different serving sizes without converting them to a common basis.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Tip 2: Compare per 100 g or 100 ml
A common reference amount makes similar products easier to compare. Use it to assess sugar, saturated fat, sodium and energy when the products serve similar purposes.
A product with less sugar per 100 g may still be eaten in a larger portion. Consider both concentration and actual quantity.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Tip 3: Understand energy units
Labels may show kilocalories (kcal), kilojoules (kJ) or both. Energy matters, but it is not the only measure of a food’s nutritional quality.
A food with more energy may also provide important protein, fibre or other nutrients. Avoid judging it by one number alone.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Tip 4: Look closely at sugar
Check total sugars and ingredients. ‘No added sugar’ does not necessarily mean the food contains no naturally occurring sugars.
A sweet drink with a health-related marketing claim can still contain substantial sugar. Compare the full label.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Tip 5: Check sodium and salt
Sodium is relevant to many dietary recommendations and can be high in sauces, processed meats, snacks and ready meals. Sodium and salt are related but not identical label terms.
People with medical conditions may have personalised sodium targets. Follow clinical advice rather than relying on a generic threshold.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Tip 6: Consider saturated fat and fibre
Saturated fat is one part of evaluating foods, while fibre can support a balanced diet. Look at the whole product and its role in your meals.
A low-fat food may have high sugar or sodium. A high-fibre claim does not automatically make an otherwise unbalanced food ideal.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Tip 7: Read the ingredients and allergens
Ingredients are commonly listed in descending order by weight, subject to local labelling rules. Check for allergens and substances relevant to your dietary needs.
For food allergies, rely on the specific allergen information and suitable professional guidance; do not guess from a product name.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Tip 8: Use front-of-pack labels as a shortcut, not a substitute
Singapore’s Healthier Choice Symbol and Nutri-Grade labels can help consumers make comparisons within their intended categories. They do not replace the full nutrition panel or personal dietary requirements.
A healthier option within a product category is not a promise that unlimited consumption is beneficial.
Action to take: write down the relevant facts for your situation, choose one low-risk step, and verify the outcome before moving to the next step.
Worked example
Two fictional breakfast cereals list sugar as 9 g per 30 g serving and 6 g per 40 g serving. On a common 100 g basis, the first contains 30 g sugar per 100 g while the second contains 15 g per 100 g. The second has half the sugar concentration, although the appropriate portion and other nutrients still matter.
The example is illustrative and does not guarantee an identical outcome. Always check the specific terms, regulations or safety requirements that apply to you.
Mistakes to avoid
- Acting before verifying identity, terms or technical requirements.
- Relying on a single number or marketing claim instead of the full context.
- Making an irreversible change without a backup or recovery plan.
- Ignoring privacy, safety or accessibility needs.
- Paying for a solution before checking the actual problem.
- Failing to keep confirmation records or test the result.
Frequently asked questions
What should I do first? A nutrition panel may describe one serving rather than the entire package. If a bag contains three servings, eating the whole bag can triple the listed per-serving amount.
How do I know whether the approach is working? Compare the outcome with the original problem using observable information. Change one variable at a time where practical.
Do I need to pay for a product or service? Not necessarily. Begin with safe, available options, and purchase only when a specific need is established.
What if I am unsure? Check authoritative guidance or a suitably qualified professional before taking a step involving safety, money or sensitive information.
