They're talking about us: Lactose.help in the media
Articles, radio interviews and features: here is everything the press and media have said about Lactose.help, all built around one constant message, lactose intolerance does not mean deprivation.
Why Paying for Lactose.help Is Smart
A user recently complained: "3 lousy scans and then you have to pay." Fair reaction. But the real value of Lactose.help is not the scans, it is the certainty that what you put in your basket will not make you sick. Here is what sits behind the price tag.
The Story of Lactose.help: How a Belgian Engineer and an AI Studio Built an Ecosystem for the 70% Who Live with Lactose Intolerance
Lactose.help was born from the meeting of two complementary expertises: Gauthier de Valensart's decade of personal research into lactose intolerance, and Olivier Dubois's AI-driven methodology for turning ideas into working products in weeks. This is the story of how a single day of prototyping turned two long-held projects into a complete ecosystem: an app, a book, and educational content for the millions of people who live with lactose intolerance.
Why LLMs Get Lactose Wrong, and Why the Maximum Dose Is the Only Actionable Answer
You may have asked ChatGPT or another AI assistant which app to use to find the exact lactose content of a product. The answer is usually long, well structured, and wrong in its premises. This article explains why, with real data, and why the maximum dose approach taken by Lactose.help is in fact the best possible answer.
Lactose-Free Chocolate: What You Really Need to Know Before You Bite
For anyone with lactose intolerance, chocolate is a minefield. Most people assume dark chocolate is automatically dairy-free, but that is wrong in a surprising number of cases. This article walks through the regulation, the ingredients, the quality criteria, and offers concrete recommendations for Belgium.
What you may not know about the products you buy every week: lactose-free yesterday, containing lactose today… for the same product?
Manufacturers reformulate their products constantly, and they don't always tell you. Here is why your carefully built list of "safe products" may already be out of date, and why managing lactose intolerance is an ongoing exercise in vigilance, not a one-time setup.
Where to Find Lactose-Free Cream
Lactose-free cream is easier to find than you might think across France, Belgium, and Switzerland: here are the references available at Naturalia, Carrefour, Leclerc, Auchan, Migros, Coop, and others, along with a simple method to make your own at home using lactase.
Lactose
Lactose intolerance affects around 70% of the global population, caused by a natural decline in lactase enzyme production after weaning. When lactose isn't broken down, gut bacteria ferment it in the colon, triggering bloating, cramps, diarrhoea, and nausea. The good news is that most intolerant individuals can tolerate 6 to 12 g of lactose daily when spread across meals, meaning many foods, including aged cheeses, remain accessible. Tools like the lactose.help app, lactase supplements, and a comprehensive practical guide make managing the condition significantly easier and more precise.
Lactose Intolerance: Symptoms, Variability, and Practical Solutions
Lactose intolerance occurs when the body fails to properly digest lactose, the natural sugar in milk, leading to uncomfortable digestive symptoms. The condition varies greatly between individuals : some tolerate small amounts while others react severely. Common symptoms include abdominal cramps, bloating, flatulence, and diarrhea, typically appearing 30 minutes to 2 hours after consumption. However, diagnosis can be tricky as symptoms often overlap with other conditions, and not everyone who malabsorbs lactose experiences symptoms. Medical consultation is essential for proper diagnosis and management.
Lactose Intolerance Test
Online questionnaires claiming to diagnose lactose intolerance are unreliable and scientifically insufficient. Research shows that self-reported symptoms often don't match objective medical test results, with studies demonstrating only 47% sensitivity for homemade questionnaires. Accurate diagnosis requires validated medical tests like hydrogen breath testing or genetic testing, performed under clinical supervision. While at-home medical kits exist, they are regulated laboratory devices, not simple web quizzes. For proper diagnosis, consult a healthcare professional for evidence-based testing rather than relying on unreliable online tools.
Relieving Lactose Intolerance Symptoms After a Slip-Up or Mistake ;)
After giving in to ice cream or tiramisu, your stomach painfully reminds you. This article explains how to minimize the damage caused by lactose with immediate measures: fractional hydration, minimalist diet, local heat, and symptomatic medications. It also presents long-term solutions for better living with lactose intolerance, including a practical guide validated by certified dietitians and a barcode scanning app to detect hidden lactose.
List of Dairy Products by Increasing Lactose Concentration
A new practical guide, 'Living Better with Lactose Intolerance,' reveals that 76% of the 133 AOC, AOP, and PGI-designated cheeses in the European Union contain 0.5g of lactose or less per 100g, making them compatible with lactose intolerance. In contrast, most other dairy products such as milk, cream, and yogurt remain too high in lactose for the majority of intolerant individuals. According to an EFSA study, lactose-intolerant people can typically tolerate between 6 and 12g per day spread across three meals, with 1g per meal being safe for all forms of intolerance. The companion app lactose.help goes even further by analyzing lactose content at the individual product level rather than by designation alone, offering greater precision for those managing their diet.
Raclette, Fondue, Tartiflette, Mont d'Or : The Lactose-Intolerant's Winter Guide
Winter comfort foods like raclette, fondue, tartiflette, and Mont d'Or are not off-limits for lactose-intolerant people : it's all about choosing the right cheeses. Aged cheeses such as Raclette du Valais AOP, Gruyère AOP, Vacherin Fribourgeois AOP, and Reblochon naturally contain very little lactose thanks to their extended aging process. According to EFSA, most lactose-intolerant individuals can tolerate between 6 and 12g of lactose per day, and the cheeses featured here contain at most 0.5g per 100g. The Lacto-Score, a five-level scale inspired by the Nutri-Score, helps consumers instantly identify whether a product is safe for them. With the right knowledge and tools, generous 200g portions of these beloved dishes are entirely achievable, no lactase supplement required.
Lactose free milk
Lactose-free milk is simply regular milk treated with lactase, an enzyme that breaks down lactose into glucose and galactose. This process explains why it tastes sweeter, not because of added sugar, but because these simpler sugars have a higher sweetening power. Importantly, the glycaemic index remains comparable to regular milk. Making lactose-free milk at home is surprisingly easy: just add a few drops of liquid lactase to any milk of your choice and refrigerate for 24 hours. For those seeking to better understand and manage lactose intolerance, a comprehensive practical guide is also available.
Lactose intolerant ? Scan Any Product, Know Instantly If It's Safe
Lactose.help is a mobile app designed to help lactose-intolerant people easily identify safe products while shopping. By simply scanning a barcode or photographing a label, the app analyses ingredient lists and nutritional data to estimate lactose content within seconds. It uses a clear five-level Lacto-Score system (A to E) inspired by the Nutri-Score, making results immediately understandable at a glance. The app combines barcode recognition, food databases, and AI-powered image analysis to cover even products not yet listed in its database. It is intended for lactose-intolerant individuals and is not a substitute for medical advice or suitable for those with a milk protein allergy.
Lactose free cheese
Many traditional and protected designation of origin (PDO) cheeses are naturally compatible with lactose intolerance, even without a 'lactose-free' label. Because lactose appears directly in the nutrition table under sugars, consumers can easily assess their exposure. Research shows that 76% of EU PDO cheeses contain 0.5g or less of lactose per 100g, well within the 1g per meal threshold tolerated by virtually all lactose-intolerant individuals. Tools like the Lacto-Score app and the book 'Living Better with Lactose Intolerance' help consumers make informed, confident dairy choices without paying a premium for specialty products.

lactose.help on BX1: when lactose intolerance takes the spotlight on "Il y a du Neuf"
lactose.help was featured on BX1's "Il y a du Neuf" to deliver a clear message: lactose intolerance doesn't mean giving up dairy. Through our book and app, we're making daily life easier for those who need to adapt how they consume dairy products.
European Dairy Tour - Stage 10: Brussels (Belgium) 🇧🇪
Brussels, Belgium: back home to conclude this European dairy tour! Belgium is well served with lactose-free products (Dilea, Ballade, store brands) for milk, cream and butter. However, Dilea lactose-free cheeses are unnecessary: traditional Belgian cheeses (Chimay, Passendale, Maredsous, Oud Brugge, Père Joseph...) are naturally rated A or B. Choose artisanal, it's better, cheaper and compatible with an intolerance!
European Dairy Tour - Global Summary 🇪🇺
European Dairy Tour: summary of 5,500 km by train across 9 countries in 12 days! Great news for the lactose intolerant: the majority of European artisanal cheeses are naturally low in lactose (rated A or B). The exceptions to avoid: ricotta, sérac, mascarpone, burrata, processed cheeses and fresh cheeses. Lactose-free products available everywhere except France and England. Find the complete list of cheeses by country and classification to travel with peace of mind.
European Dairy Tour - Stage 9: London (United Kingdom) 🇬🇧
London, United Kingdom: good news for the lactose intolerant, most British cheeses are rated A or B! As for lactose-free products, the choice remains limited, just like in France.
European Dairy Tour - Stage 8: Paris (France) 🇫🇷
Paris, France: a stage dedicated to cheese shops, the preferred place for advice for lactose-intolerant people. The concept of a cheese shop is very French, and Paris is full of them. Cheesemongers know the subject but are sometimes too restrictive. Favour artisanal products (milk, rennet, ferments, salt) and check the nutritional composition. A lactose-intolerant person can digest at least 1 g of lactose per meal, meaning 200 g of a cheese rated B.
European Dairy Tour - Stage 7: Barcelona (Spain) 🇪🇸
Barcelona, Spain: an easy stop for lactose-intolerant travellers with a wide range of lactose-free products in supermarkets (milk, cream, butter, whipped cream, yoghurt). For cheeses, go for "viejo", "añejo" or "curado" (aged, rated A or B) and avoid "fresco" (fresh, rated D or E). Warning: goat's or sheep's milk doesn't guarantee a low-lactose cheese, it all depends on the ageing process!
European Dairy Tour - Stop 6: Avignon 🇫🇷
Avignon, France: a surprising stop due to the lack of lactose-free products in supermarkets, despite 15% of French people being lactose intolerant and symptomatic. Only Naturalia offers the essentials (milk, butter, cream), but good news: 76% of French PDO/PGI cheeses are rated A or B, meaning they're compatible with lactose intolerance. Roquefort, Camembert de Normandie, Cantal, Mont d'Or... France's cheese heritage remains accessible to those who know how to choose wisely.
European Dairy Tour - Stop 5: Collombey 🇨🇭
Discover Switzerland through the eyes of a lactose-intolerant traveller: an immersive visit to a Valais dairy farm producing award-winning Raclette AOP, plus a comprehensive guide to Swiss cheeses that are naturally low in lactose. From train adventures to ski touring and fondue dinners, learn why Switzerland is paradise for cheese lovers with lactose intolerance.
European Dairy Tour - Stop 4: Florence 🇮🇹
Florence, Italy: a rich discovery for lactose-intolerant travellers. Impressive "senza lattosio" sections at Lidl, Esselunga, and Conad, but beware: unlike alpine countries, Italy offers cheeses ranging from A to E, so vigilance is key. Parmigiano, Grana Padano, Pecorino Romano, and Provolone are safe (A), mozzarella di bufala is B, but avoid ricotta, stracchino, and fiocchi di latte (E).
European Dairy Tour - Stop 3: Graz 🇦🇹
Travelling to Austria with lactose intolerance? Discover local cheeses, lactose-free ranges at Spar and Billa, and practical tips for eating safely when lactose intolerant.
European Dairy Tour - Stop 2: Prague 🇨🇿
A lactose-intolerant traveler explores Prague's dairy scene, finding it more challenging than Munich due to fewer allergen menus and untrained restaurant staff. However, Czech supermarkets reveal a treasure trove of Central European dairy products. The key discovery: unlike Western Europe where products tend to be either very safe or completely off-limits, Central European dairy often falls into intermediate risk categories, requiring more careful scanning but offering more variety for the adventurous lactose-intolerant traveler.
European Dairy Tour - Stop 1: Munich 🇩🇪
During the European dairy tour, I first stop in Munich. The dairy product offerings for those with lactose intolerance reveal a favorable situation: many cheeses rated A (Gruyère, Emmentaler, Gouda), lactose-free ranges (MinusL, LAC), a wide vegan selection, and excellent allergen labeling in Rewe and Edeka supermarkets, making the trip comfortable for this community.
