Learn to Read Food Labels: Hidden Sugars Are Everywhere

Chapter 47 · Vihang Rahul Vasa

One of the most important life skills for a person with diabetes is learning to read food labels. Many packaged foods marketed as “healthy,” “diet,” or “no added sugar” are not what they appear to be. A product labelled “no added sugar” may still be loaded with carbohydrates that convert to glucose in your body. Such a label is a marketing claim, not a medical promise: it tells you only that table sugar was not added. A fruit juice marketed as “100% natural” can contain as much sugar as a soft drink.

• Always check the “Total Carbohydrates” on the nutrition label, not just “Sugar.” It is the total carbohydrate content that affects your plasma glucose (blood sugar).

• Look for hidden sugars listed under different names: sucrose, fructose, maltose, dextrose, corn syrup, honey, agave, and fruit concentrate are all forms of sugar.

• Be especially cautious with fast food and restaurant meals. They often contain far more sugar, salt, and unhealthy fats than you would expect. A single fast-food meal can cause a dramatic plasma glucose (blood sugar) spike that lasts for hours.

• Prefer whole, unprocessed foods over packaged ones. A short ingredient list can be a helpful first clue, but it is not a reliable measure of nutritional quality on its own: read what the ingredients actually are, and check the sugar, salt, and fat content.

• When in doubt, check the glycaemic index (GI) of a food item: low GI foods release sugar slowly into the bloodstream, while high GI foods cause rapid spikes.

Shopping for Groceries: My Experience with the Grocery, Vegetable and Fruit Market

This is my own habit, built over years of buying groceries, fruits and vegetables myself. It is not a rule for anyone else. It is what has worked for me.

• Fresh first. I fill the basket with fresh vegetables, fruits, pulses and grains before I look at anything in a packet.

• Ready-to-eat and ready-to-cook: I avoid. Instant mixes, heat-and-eat meals, packaged snacks. In my experience they carry more salt, oil and hidden sugar than anything cooked at home.

• I read the label every time, and not only the front. The ingredient list and the nutrition table on the back tell me what is actually inside.

• If the label confuses me, or is written in a language I do not read, I take a photo of it with my phone and ask the Artificial Intelligence (AI) on the phone to explain what each ingredient is and what it may do to plasma glucose (blood sugar). Many phones can do this now. A food label is public information printed by the maker: it is not my medical report, and Chapter 15 still stands: my reports go to my doctor, not to AI. Even with a label, AI can make mistakes, so I still read it myself.

• Fruits: I pick the ones with a low Glycaemic Index (GI), and I keep the very sweet ones small and occasional (see Chapter 45).

• If I cannot understand what is in a packet, it does not come home.

The simple test I use: the fewer the ingredients, and the closer the food is to how it grew, the better it has been for me.

Chapter 47 Read beyond the food label: total carbohydrates matter, not sugar alone. Check sugars, salt, fat and ingredients including sucrose, fructose, syrup and honey. No added sugar does not mean no carbohydrates. Check AI explanations with the treating doctor; fresh foods come first.
