How to Read a Food Label: the 60-second method


A product can display “organic,” “natural,” and “no added sugar” and 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 or prior training.

What You’ll Learn in This Article

The food industry invests considerable sums in front-of-pack communication. Claims on the front of the package — “source of fiber,” “high in protein,” “light” — have very precise legal definitions that often have little to do with the product’s actual nutritional quality. Everything happens on the back of the package, in the ingredients list and the nutrition facts table.

In this article, you’ll learn to identify the 12 hidden names of sugar, use the NOVA classification to distinguish real foods from industrial products, understand why the “organic” label is not a blank check — and apply a three-question reading method that takes less than twenty seconds in the supermarket aisle.

The Anatomy of a Label: The 4-Step Method

Before looking at the Nutri-Score or the claims on the front, turn the package over. Everything that matters is on the back, in two distinct areas: the ingredients list and the nutrition facts table. These two sections 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 ingredients list runs from the most abundant to the least abundant. If sugar appears among the first three, the product is primarily sweetened — regardless of the “no added sugar” claim on the front. “No added sugar” only means that no conventional white sugar was added on top of the sugars naturally present in the ingredients. It says nothing about the product’s actual sugar content.

Glucose-fructose syrup Dextrose Maltose Corn syrup Agave syrup Rice syrup Fruit juice concentrate Date purée Coconut sugar Rapadura Maltodextrin Whole cane sugar

Glucose-fructose syrup deserves particular attention: its glycemic index is very high, and it is metabolized differently from conventional sucrose, with a more pronounced impact on the liver and insulin resistance. Maltodextrin, often presented as a “starch,” has a higher glycemic index than white sugar—it is sugar in every functional respect, without the name that would make it easy to identify.

The 4-step method—60 seconds flat

1

Count the ingredients

More than five ingredients is an initial warning sign. More than ten is a reason to read carefully. The length of the list is not an absolute rule, but it correlates with the degree of industrial processing.

2

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 what the front-of-pack label says. The list is ordered by weight in descending order: what comes first is present in the greatest amount.

3

Look for “E” numbers

Not all of them are problematic—E300 is vitamin C, and E306 is a 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 the context of hormonal or intestinal vulnerability.

4

Read the nutrition facts panel “per 100 g,” never “per serving”

Serving sizes indicated by manufacturers are often undersized compared with actual consumption. Only the “per 100 g” basis allows products to be compared objectively and without bias.

The trans fat trap

In the nutrition facts panel, the line “of which saturated fats” should account for less than one-third of total fat. A “of which trans fats” line above zero is an absolute red flag: even very small amounts of trans fats increase cardiovascular risk, disrupt estrogen signaling, and promote systemic inflammation—a mechanism of particular concern during menopause.


Identify ultra-processed foods — the NOVA classification

The NOVA classification, developed by researchers at the University of São Paulo, does not assess the nutritional quality of a food—it measures its degree of industrial processing. This distinction is fundamental because a product may be low in calories, high in protein, and still contain additives that disrupt the gut microbiome, the hormonal axis, and satiety signaling.

NOVA classification—4 levels of industrial processing
1
Unprocessed or minimally processed foods
Fruit, vegetables, fresh meat, eggs, dried legumes, fresh fish, plain milk
The foundation of any anti-inflammatory diet—to consume without restriction
2
Processed culinary ingredients
Oils, butter, flour, salt, sugar, vinegar—ingredients extracted from NOVA 1 foods
Used in cooking, not eaten alone—acceptable in this context
3
Processed foods
Canned foods, cheeses, simple cured meats, jarred vegetables, artisan bread, smoked fish
Acceptable in moderation—read the ingredients to confirm the absence of industrial additives
4
Ultra-processed foods—to minimize
Products containing ingredients absent from any home kitchen: emulsifiers, thickeners, flavor enhancers, colorings, artificial flavors, texturizing agents
Sodas, ready-made meals, sugary breakfast cereals, industrial biscuits, sliced bread, nuggets, most flavored yogurts—including some certified organic products

The rule of ingredients that are impossible to pronounce

A simple and effective rule of thumb: if you see an ingredient that you would not be able to buy as-is at a market or grocery store—starch acetate, polydextrose, modified sunflower lecithin, microcrystalline cellulose—it is an industrial ingredient characteristic of NOVA 4 products. This is not an absolute rule, but it is a quick filter to direct your attention toward a more careful reading.


The “organic” label trap: what certification does not guarantee

The organic label certifies the absence of synthetic pesticides in agricultural production. This is relevant and verifiable information. What it does not say—and what many people overlook—is just as important.

What “organic” really guarantees

Agriculture without synthetic pesticides. No GMOs in ingredients of agricultural origin. Livestock raised with outdoor access. A limited list of permitted additives (about 50 compared with 350 in conventional production). No artificial synthetic flavors.

What “organic” does not guarantee

A low sugar content. The absence of industrial processing. A high Nutri-Score. The absence of packaging at risk of chemical migration. Local sourcing or consistent control standards across countries.

An organic biscuit can contain 30 g of sugar per 100 g in the form of “whole cane sugar” or “apple juice concentrate.” The glycemic impact is identical to that of white sugar. An organic boxed soup with twelve ingredients is a NOVA 3 or 4 product—organic, certainly, but no less processed for it. The Nutri-Score of many organic products is C or D: the organic label says nothing about nutritional density.

The 5 real criteria of a good processed product

1. Fewer than five recognizable and pronounceable ingredients. 2. Sugar does not appear among the first three ingredients in any of its forms. 3. No three-digit E codes among the first ten ingredients, except E300 (vitamin C) and E306 (tocopherols). 4. Saturated fats account for less than one-third of total fat—zero trans fat. 5. At least 2 g of fiber per 100 g, which excludes nearly all ultra-processed foods. These five criteria do not replace a complete label review, but they make it possible to sort products in thirty seconds in the supermarket aisle.


Why ultra-processed foods worsen menopausal symptoms

The question is not insignificant. During menopause, several biological mechanisms that are already weakened are directly disrupted by regular consumption of ultra-processed foods—and understanding these mechanisms changes how we approach our daily food choices.

Emulsifiers (E471, E472, carrageenans) disrupt the composition and permeability of the gut microbiome. This is significant because it is in the gut that dietary phytoestrogens—isoflavones from soy and lignans from flax—are converted into active molecules by specialized bacteria. An altered microbiome directly reduces the bioavailability of phytoestrogens, diminishing their effect on hot flashes and menopausal discomfort.

High-glycemic-index sugars amplify the insulin resistance already intensified by the drop in estrogen—promoting abdominal fat storage, unstable blood sugar, and the characteristic afternoon cravings that many women describe during menopause.

Trans fats and refined oils increase low-grade systemic inflammation. Inflammation is one of the factors that amplify the frequency and intensity of vasomotor symptoms—hot flashes and night sweats—according to several epidemiological studies published in Menopause and the Journal of the North American Menopause Society.

Finally, some additives classified as potential endocrine disruptors—BHA (E320), BHT (E321), and certain azo dyes—may interfere with estrogen receptors, worsening an already existing hormonal instability. These findings remain partly preliminary for some additives, but the precautionary principle applies all the more because menopause is already a period of endocrine vulnerability.

Clinical perspective

Reducing ultra-processed foods is one of the most accessible and least costly ways to improve menopausal comfort. Not because they are a direct cause of menopause symptoms, but because they amplify several of the biological mechanisms that influence their intensity. This is a fundamental nutritional intervention, not a shortcut.


Frequently asked questions

Question 1Is the Nutri-Score reliable for choosing a good product?
The Nutri-Score is a useful but limited tool. It assesses nutritional composition—calories, sugars, fats, fiber, and protein—but completely ignores the degree of industrial processing. A zero-sugar soda can receive a B or C because it contains no calories, even though it contains sweeteners that alter the microbiome. Extra-virgin olive oil—one of the best foods for cardiovascular and hormonal health—often receives a D because of its high fat content. Use the Nutri-Score as a first filter, never as the sole criterion.
Question 2Does "no added sugar" really mean sugar-free?
No. "No added sugar" means that the manufacturer has not added any sugar beyond the sugars naturally present in the ingredients. A 100% pure orange juice with no added sugar contains around 10 g of free sugar per 100 ml—a quantity comparable to that of a soft drink. To find out the actual sugar content, read only the "of which sugars" line in the nutrition facts table.
Question 3Are sweeteners a good alternative to sugar during menopause?
The question is more nuanced than it may seem. High-intensity sweeteners — aspartame, sucralose, acesulfame K — provide no calories but are not neutral. Recent studies suggest that they alter the composition of the gut microbiome, disrupt insulin signaling, and reinforce a preference for sweet flavors. During menopause, when the microbiome and insulin sensitivity are already compromised, regular consumption deserves to be limited. If you want to sweeten things, small amounts of raw honey or maple syrup remain preferable — without idealizing them, since they are still sugars.
Question 4Can you eat processed foods and stay healthy?
Absolutely. The goal is not all-or-nothing, but proportion. Epidemiological studies show that the health problems associated with ultra-processed foods appear when they account for more than 20 to 30% of daily calorie intake. Build each meal around NOVA 1 foods — vegetables, unprocessed animal or plant proteins, unprocessed whole grains — and treat ultra-processed products as occasional indulgences, not dietary staples. It is a rule of proportion, not exclusion.
Question 5How can you spot food greenwashing on packaging?
The most common warning signs: green or brown colors without official certification; terms such as "natural," "authentic," or "traditional" that have no binding legal definition; a "preservative-free" claim on a product containing salt or sugar (which are preservatives); "made with real strawberries" when the strawberry is the eighth ingredient; farm images on a product manufactured entirely in an industrial facility. The rule is simple: official certifications (AB, Label Rouge, AOC, AOP) have verifiable legal value. Marketing claims do not.
