Looking for an American mustard with no added sugar that delivers the classic ballpark flavour without compromising on the ingredients?

It works well on hot dogs and burgers, in sandwiches and wraps, or as a base for quick dressings.
Why we added fu:di to the PraveBio range
Fu:di is a British food brand from London that aims to support metabolic health through everyday food. Its recipes are “crafted by chefs, backed by science” – developed from founder Tom’s cooking experience and built around the ingredients used: no added sugar, no seed oils and an emphasis on lower carbohydrate content in familiar condiments.
Fu:di reworks familiar recipes – from ketchup and mustard to mayonnaise and dressings – to keep the flavours recognisable and distinctive, with straightforward ingredients and no hidden sugar. These are not bland “diet” sauces, but products with a clear flavour profile for people who pay attention to sugar and carbohydrate intake and to the ingredients in the condiments they use every day.
fu:di American Mustard with no added sugar
American Mustard is a classic American mustard inspired by the bottles found at New York hot dog stands and street delis. It has a bright yellow colour, smooth texture and a tangy flavour with a mild heat. Use it wherever you want that classic ballpark mustard style – on hot dogs, burgers, sandwiches or with chips.
The recipe has no added sugar, no seed oils and is low carb – with just 0.3 g of carbohydrate per serving. Its flavour comes from mustard seed, vinegar, sea salt and turmeric, with no sweeteners or unnecessary additives.
In the kitchen, it works as a quick condiment for grilled meat, sausages, sandwiches, wraps or cold platters. It also works well in simple homemade dressings: just mix it with oil, a little vinegar or lemon juice and, if you like, a spoonful of mayonnaise.
Standard hot dog mustards and other condiments are often sweetened and made with refined seed oils. For some people, this is a reason to limit them – with frequently used sauces, sugar and fat can easily add up in an everyday diet. Here you have a straightforward mustard with no added sugar, very little carbohydrate and an ingredient list you can read in seconds.

Did you know?
- American mustard typically has a bright yellow colour from turmeric and is usually milder than Dijon mustard.
- Mustard seed is the main ingredient in mustard – its flavour develops when it comes into contact with low-pH media (vinegar, water) and salt.
- Simple ingredients (water, mustard, vinegar, salt, spices) are typical of mustard – there is no need for starch or thickeners.
Tip: for a homemade ballpark-style hot dog, all you need is a grilled sausage, a bun, this mustard and a few pieces of pickled gherkin.

Why choose fu:di
Fu:di is a brand of condiments and other foods that reworks familiar recipes towards a lower sugar and carbohydrate content, while also emphasising the absence of seed oils. The phrase “crafted by chefs, backed by science” reflects its combination of cooking experience and scientific research into dietary composition.
The brand works on the principle of choosing flavour rather than going without it: offering ketchup, mustard, mayonnaise, dressings and other products that are as easy to use as conventional condiments, but with adjusted recipes – no added sugar, no seed oils and a focus on straightforward ingredient lists.
Founder Tom draws on years of experience in professional kitchens and focuses on making products that work in everyday cooking – in sandwiches, salads, marinades and quick sauces. The second part of the approach is explaining the “why” – why a particular combination of ingredients is used and how it fits into overall carbohydrate and fat intake.
The result is a range aimed at customers who pay attention to sugar, carbohydrates and the ingredients in everyday condiments, without giving up distinctive flavours and familiar classics such as ketchup, mayonnaise or mustard.

FAQ
What sweetens fu:di American Mustard if it contains no sugar?
Fu:di mustard contains no added sugar, corn syrup or artificial sweeteners. Its gently sweet flavour comes from the ingredients and spices used. It contains just 1.3 g of naturally occurring sugars per 100 g, a fraction of the amount found in standard commercial mustards.

What does “no seed oils” mean?
Many conventional dressings and sauces contain inexpensive refined oils such as rapeseed and sunflower oil, which are rich in omega-6 fatty acids. Fu:di does not use these oils. This American mustard is made from water, vinegar and mustard seeds, with no added fat or seed oils.

Is this mustard suitable for a strict keto or low-carb diet?
Yes, it is suitable for keto and low-carb diets. With just 0.3 g of carbohydrate per serving, it has minimal impact on the glycaemic response and helps maintain ketosis. It is therefore suitable for low-carb and keto diets.

Does the product contain any artificial preservatives or colours?
No. Fu:di achieves the bright yellow colour naturally using turmeric. Preservation comes from the natural pH of the vinegar and the sea salt. The product has straightforward ingredients, with no added colours or artificial preservatives.

How does NYC-style mustard compare with classic Czech full-fat mustard?
Fu:di American Mustard is milder, with a more pronounced vinegary note and less heat than classic Czech full-fat mustard. It gives food the tang and freshness associated with New York hot dogs.

Is the product suitable for vegans and people with coeliac disease?
Yes. The ingredients are entirely plant-based and naturally gluten-free. The main ingredients are water, mustard seed, vinegar and spices, so the product is suitable for vegans and people with coeliac disease.

Why is the mustard packaged in a black opaque bottle?
The opaque squeeze bottle protects the ingredients from light, which could affect the colour and flavour of the mustard. It also allows for clean, precise dispensing directly onto your food.

How long does the mustard keep, and how should it be stored?
Thanks to natural preservation from vinegar and salt, the product has a shelf life of several months. Store it in a dry place and keep refrigerated after opening to help preserve its aroma.

What does “fu:di hack” on the packaging mean?
The term “hack” refers to products that replace conventional food options with versions that have simpler ingredient lists. It is a reworked version of a classic product that lets you enjoy familiar foods without added sugar.

Who is the exclusive importer of fu:di in the Czech Republic?

Who is behind fu:di®
Founders Tom and Ben combine cooking experience with a scientific approach to nutrition. They create products that are flavourful, low in carbohydrate and focused on supporting metabolic health. Their philosophy is to offer “food first” products that bring together flavour and nutrition without compromise.
The vision and mission of fu:di®
Fu:di® aims to make flavourful, healthy, low-carbohydrate foods more accessible, supporting metabolic health, stable energy and enjoyment of food – without compromising on flavour.
The mission of fu:di® is to make nutritious food easier to enjoy. The range includes sugar-free ketchup, mayonnaise made with quality oils and dressings without industrial additives, supported by scientific insight and clear information.
For fu:di®, transparency means more than simply listing what a product contains. The brand also explains the reasons behind the choice of individual ingredients and the way each recipe is formulated. This helps customers better understand the ingredients in everyday foods and make decisions based on clear information.

Quality control and certification
Fu:di® products are free from palm oil, added sugar, preservatives and fillers. They use free-range eggs, extra virgin olive oil and avocado oil, as well as plant-based sweeteners (erythritol, inulin, stevia). Ingredients are carefully selected, packaging is recyclable and nutritional values are clearly stated.
The fu:di® story

The story of fu:di® began with founder Tom’s personal experience. Although food had been at the centre of his professional life and he usually cooked at home, he gradually struggled with excess weight and was diagnosed with prediabetes at the age of 39. He therefore decided to reduce sugar and carbohydrates, without giving up flavour or shared moments around food.
In his own kitchen, he began adapting favourite everyday recipes. He first created ketchup, followed by other sauces, mayonnaise, baked goods and breakfast mixes. His aim was to make foods with carefully considered ingredients that did not feel like a compromised diet alternative, but still delivered full flavour and enjoyment.
Tom was joined by his long-time friend Ben, a former academic who worked in mathematics and statistics at Imperial College London. He combined Tom’s culinary experience with analysis of scientific research and an interest in metabolic health. Their shared approach led to the creation of fu:di® – food crafted by chefs and backed by science.
Developing fu:di® products led Tom and Ben to take another step. While looking for oils suitable for their recipes, they found that commonly used fats often did not meet their requirements and that not all avocado oils offered the same quality.
They therefore founded the related brand GOOD PHATS, focused on carefully selected olive and avocado oils, ghee and other fats for different types of cooking. This gave them a high-quality foundation consistent with the fu:di® philosophy, while also making the same ingredients available to customers for everyday use.
