How to read food labels to reduce added sugars and unhealthy fats
Reading food labels can quickly help you cut added sugars and unhealthy fats without guessing. With a few habits you can spot sneaky ingredients, compare products in 30–60 seconds, and make healthier swaps that still taste good. This guide gives practical steps you can use at the grocery store or when ordering packaged foods.
Step 1: Start with the serving size
Check the serving size and number of servings first — most packages list values per serving, not the whole container. If the package contains two servings but you eat the whole thing, double the grams of sugar, saturated fat, and calories to know what you’re actually consuming.

Step 2: Look at total sugars and added sugars
Find both Total Sugars and Added Sugars (grams) on the label; prioritize products with 5 g or less added sugar per serving and avoid those over 12 g per serving. If only Total Sugars is listed, compare ingredient lists for obvious sweeteners like sugar, corn syrup, honey, or maltose near the top.

Step 3: Compare saturated and trans fats
Check Saturated Fat and Trans Fat values: aim for less than 3 g saturated fat per serving and 0 g trans fat. If a product lists 'partially hydrogenated' oils in the ingredients, it likely contains trans fats even if the label reads 0 g per serving due to rounding.

Step 4: Read ingredient lists front-to-back
Scan the ingredient list from highest to lowest quantity; ingredients are listed by weight, so the first few items dominate the product. If sugar or a variant (sucrose, dextrose, molasses) appears within the first three ingredients, choose something with whole-foods listed earlier like fruit, whole grains, or nuts.

Step 5: Spot hidden sugar names
Learn common sugar synonyms — glucose, maltodextrin, cane juice, syrups, and words ending in -ose are all sugars. When you see multiple sugar types listed separately, add their numbers mentally: three ingredients of 2–3 g each per serving can quickly total 8–10 g added sugar.

Step 6: Watch for refined fat sources
Identify oils and fats in the ingredient list: avoid 'partially hydrogenated' and prefer products with olive oil, canola, or nut oils higher on the list. Trans and highly processed saturated fats often come from hydrogenated or palm oils listed near the top of baked goods and snacks.

Step 7: Use the % Daily Value smartly
Use % Daily Value (%DV) to compare: 5% DV or less per serving is low, 20% DV or more is high for nutrients like saturated fat and added sugars. Compare similar products and choose the one with lower %DV for saturated fat and added sugars while keeping protein and fiber higher.

- Bring a short reference card with thresholds: ≤5 g added sugar, ≤3 g saturated fat, 0 g trans fat per serving to shop in 30–60 seconds.
- Use whole foods like fresh fruit, plain yogurt, and nuts as swaps — a 150 g apple or 170 g plain yogurt typically has less added sugar than flavored alternatives.
- When comparing sizes, divide package totals by serving size to get grams per 100 g for fair comparison when labels differ.
- Favor products with at least 2–3 g fiber per serving to help blunt sugar surges and improve satiety.
- If ingredient lists are long (10+ items), prefer simpler short lists with recognizable whole-food ingredients.
- Check labels at different times — reformulations happen, so re-check favorite products every 6 months.
- 'No added sugar' does not mean low-calorie — some products contain fruit concentrates or natural sweeteners with similar calories, so still check grams per serving.
- '0 g trans fat' can be listed if the amount is under 0.5 g per serving — eat multiple servings and trans fat can add up, so avoid 'partially hydrogenated' oils on the ingredient list.
- Serving sizes can be misleading on shareable packages; always confirm how many servings you actually eat and multiply values accordingly.
- Products marketed as 'low-fat' often have more added sugars to compensate; compare both sugar and fat content rather than relying on front-pack claims.
