💡 Smart Nutritional Guidance
Consumption advice
Udon is made from wheat flour, so don’t make it the only main ingredient in the bowl; fill it with dashi broth, a boiled egg, spinach and shiitake mushrooms for a balanced meal.
Best preparation methods
Cook udon al dente and don’t overcook it, so the gluten network doesn’t break down and turn it into fast-absorbed sugar.
Important Nutritional Note

Frequently asked questions
Do udon noodles make you gain weight?
A filling portion (200 g cooked) contains 260 kcal and 51.6 g available carbohydrate. With a clear broth and vegetables it is a moderate meal, but with fried toppings and thick sauces it will certainly add weight.
Is udon gluten-free?
No. Classic udon is made from high-gluten white wheat flour, which gives it its typical chewy texture, so it is not suitable for people with coeliac disease.
What is the nutritional value of a 200 g bowl?
It gives you 260 kcal, 8 g protein, 1 g fat and 51.6 g available (net) carbohydrate.
