How to Read a Food Label: The 60-Second Method
A product can claim to be "organic," "natural," "no added sugar," and yet contain six additives, twenty-two grams of sugar, and trans fats. These claims are not lies—they are legally permitted half-truths. This guide gives you the tools to decode any label in under a minute, without an app, without prior training.
What you will learn in this article
The food industry invests considerable sums in superficial communication. Front-of-pack claims—"source of fiber," "rich in protein," "light"—have very precise legal definitions that often bear little relation to the product's actual nutritional quality. Everything that matters is on the back of the package, in the ingredient list and the nutrition facts table.
In this article, you will learn to identify the 12 hidden names of sugar, to use the NOVA classification to distinguish real foods from industrial products, to understand why the "organic" label is not a blank check—and to apply a three-question reading method that takes less than twenty seconds in the supermarket aisle.
Anatomy of a label: the 4-step method
Before looking at the Nutri-Score or front-of-pack claims, turn the package over. Everything that matters is on the back, in two distinct areas: the ingredient list and the nutrition facts table. These two areas are regulated and contain information that front-of-pack marketing cannot hide—provided you know how to read them.
The 12 hidden names of sugar
The ingredient list goes from most present to least present. If sugar is among the first three ingredients, the product is primarily sugary—regardless of the "no added sugar" claim on the front. The "no added sugar" claim only means that no classic white sugar has been added in addition to sugars naturally present in the ingredients. It says nothing about the actual sugar content.
Glucose-fructose syrup deserves particular attention: its glycemic index is very high and it is metabolized differently from classic sucrose, with a more marked impact on the liver and insulin resistance. Maltodextrin, often presented as a "starch," has a higher glycemic index than white sugar—it is a sugar in all functional respects, without the appellation that would allow it to be easily identified.

Count the ingredients
More than five ingredients is a first signal. More than ten, a reason to read carefully. The length of the list is not an absolute rule, but it correlates with the degree of industrial processing.
Look for sugar among the first three ingredients
If it appears there—under one of its twelve names—the product is primarily sugary, regardless of the front-of-pack claim. The list is ordered by decreasing weight: what comes first is what is most present.
Spot the "E" codes
Not all of them are problematic—E300 is vitamin C, E306 is natural tocopherol. But E621 (monosodium glutamate), E951 (aspartame), E407 (carrageenans) or E471–E472 (mono and diglycerides of fatty acids) are documented warning signs, particularly in contexts of hormonal or intestinal fragility.
Read the nutrition facts table "per 100g," never "per serving"
Portions indicated by manufacturers are often undersized compared to actual consumption. Only the "per 100g" basis allows objective and unbiased comparison of products.
In the nutrition facts table, the "of which saturated fatty acids" line should represent less than one-third of total fats. A "of which trans" line greater than zero is an absolute red flag: trans fats, even in very small quantities, increase cardiovascular risk, disrupt estrogen signaling, and promote systemic inflammation—a particularly concerning mechanism during menopause.
Identifying ultra-processed foods — the NOVA classification
The NOVA classification, developed by researchers at the University of São Paulo, does not judge the nutritional quality of a food—it measures its degree of industrial processing. This distinction is fundamental, because a product can be low in calories, rich in protein, and still contain additives that disrupt the intestinal microbiota, the hormonal axis, and satiety signaling.
A simple and effective heuristic: if you read an ingredient that you wouldn't be able to buy as such in a market or grocery store—starch acetate, polydextrose, modified sunflower lecithin, microcrystalline cellulose—it's an industrial ingredient characteristic of NOVA 4 products. This is not an absolute rule, but it's a quick filter to direct your attention to more careful reading.
The "organic" label trap: what certification doesn't guarantee
The organic label certifies the absence of synthetic pesticides in agricultural production. This is relevant and verifiable information. What it doesn't say—and what many ignore—is just as important.
Agriculture without synthetic pesticides. No GMOs in agricultural ingredients. Free-range farming. Reduced list of authorized additives (around 50 vs. 350 in conventional). No artificial synthetic flavors.
Low sugar content. Absence of industrial processing. A high Nutri-Score. Absence of packaging with chemical migration risk. Local origin or uniform control standards across countries.
An organic biscuit can contain 30g of sugar per 100g in the form of "whole cane sugar" or "apple juice concentrate". The glycemic impact is identical to that of white sugar. An organic brick soup with twelve ingredients is a NOVA 3 or 4 product – organic, certainly, but no less processed for all that. The Nutri-Score of many organic products shows a C or D: the organic label says nothing about nutritional density.
1. Fewer than five recognizable and pronounceable ingredients. 2. Sugar does not appear in the first three ingredients in any of its forms. 3. No three-digit E-numbers in the first ten ingredients, with the exception of E300 (vitamin C) and E306 (tocopherols). 4. Saturated fats represent less than one-third of total fats – zero trans fats. 5. At least 2g of fiber per 100g, which excludes almost all ultra-processed foods. These five criteria do not replace a full reading, but allow for a thirty-second sort in the supermarket aisle.
Why ultra-processed foods worsen menopause symptoms
The question is not trivial. During menopause, several already weakened biological mechanisms are directly disturbed by regular consumption of ultra-processed foods – and understanding these mechanisms changes the way one approaches daily dietary choices.
Emulsifiers (E471, E472, carrageenans) disrupt the composition and permeability of the gut microbiota. It is in the gut that dietary phytoestrogens – soy isoflavones, flax lignans – are converted into active molecules by specialized bacteria. An altered microbiota directly reduces the bioavailability of phytoestrogens, which decreases their effect on hot flashes and climacteric discomfort.
High glycemic index sugars amplify insulin resistance already heightened by the drop in estrogen – promoting abdominal fat storage, unstable blood sugar, and characteristic afternoon cravings that many women describe during menopause.
Trans fats and refined oils increase low-grade systemic inflammation. And inflammation is one of the factors that amplify the frequency and intensity of vasomotor symptoms – hot flashes, night sweats – according to several epidemiological studies published in Menopause and the Journal of the North American Menopause Society.
Finally, certain additives classified as potential endocrine disruptors – BHA (E320), BHT (E321), certain azo dyes – can interfere with estrogen receptors, worsening an already present hormonal instability. This data remains partially preliminary for some additives, but the precautionary principle applies even more so as menopause is already a period of endocrine vulnerability.
Reducing ultra-processed foods is one of the most accessible and least costly levers to improve climacteric comfort. Not because they are a direct cause of menopause symptoms, but because they amplify several biological mechanisms that modulate their intensity. This is a fundamental nutritional intervention, not a shortcut.
