Key Areas to Check on a Food Label A. Ingredient List Look at the first few ingredients : they make up the bulk of the product. My Dynamics +1

Hidden sugars and sweeteners often appear under multiple names — like fructose, sucrose, glucose, corn syrup, maltodextrin, invert sugar, etc. Heart Foundation +1

Fats : Check for terms such as hydrogenated oils, margarine, shortening, or partially hydrogenated fats, which may indicate trans fats. My Dynamics

Sodium / salt : Look beyond “salt” — sodium can hide in sodium nitrite, monosodium glutamate (MSG), sodium bicarbonate, and other chemical names. My Dynamics

Additives : Food additives (preservatives, colours, antioxidants, emulsifiers) must be listed. Many are assigned “E‑numbers” or chemical names. EWLW +1

Best before = quality declines but not necessarily unsafe.

Use by = more serious; may imply food can spoil and become unsafe. Health

C. Claims & Marketing Terms Be wary of marketing terms like “natural,” “healthy,” or “super-food” — these aren’t always regulated and can be misleading. FoodFacts

Check whether a “low‑sugar” or “sugar-free” claim actually means what you think — there could be sweeteners, sugar alcohols, or fruit concentrates. Annelien Pienaar

Why This Matters for Health Hidden sugars and salt contribute significantly to chronic diseases like hypertension, diabetes, and obesity.

Preservatives and additives may not be harmful in small amounts, but consistent intake from ultra-processed foods could pose long-term risks.

By learning to decode the ingredient list, nutrition panel, and the marketing claims, you can make much more informed and healthier food choices. Hidden ingredients like sugars, additives, and trans fats can have a big impact on your well-being — but with label literacy, you can spot them and avoid the worst.
