How to identify hidden trans fats on food labels

Why Trans Fats Matter

Trans fats, created by hydrogenating vegetable oils, spike bad cholesterol and block arteries, doubling heart attack odds even in tiny amounts. For diabetics, they worsen blood sugar control via inflammation. Indian street snacks and biscuits often contain them despite bans.

Label Lies Exposed

Nutrition panels round down: <0.5g/serving shows as "0g," but multiple servings add up fast—like eating a whole pack of popcorn. Always flip to ingredients; serving sizes trick you into underestimating.

Red Flag Ingredients

Scan for these hidden sources:

• Partially hydrogenated oil (PHO) or vegetable oil shortening—direct trans fat makers.

• Hydrogenated oils (fully or semi)—even "fully" can form trans during processing.

• Margarine, vanaspati, or generic "vegetable fat."

• Mono- and diglycerides—may contain traces if hydrogenated.

Step-by-Step Checking

1. Read Nutrition Facts: Ignore "0g trans" if serving is tiny (e.g., 15g biscuit).

2. Hit Ingredients List: Avoid anything hydrogenated; choose "expeller-pressed" oils.

3. Calculate Total: Multiply per-serving trans by package servings.

4. Verify Claims: "No trans fat" means <0.5g/serving—still risky daily.

5. Indian Tip: FSSAI labels must list trans; skip if vague "edible vegetable fat."

Common Culprits in India

Bakery biscuits, namkeen, instant noodles, and frozen parathas hide trans via vanaspati. Even "health" bars use hydrogenated fillers. Swap for nuts, millets, or cold-pressed oils.

Healthier Swaps

Use ghee sparingly over vanaspati; pick olive/mustard oil brands without hydrogenation. Home-cook to eliminate risks entirely for stable blood sugar.
