Why does Japanese Katsu Curry receive a Nutri‑Score of E, and which nutrients are responsible for this low rating?

The Nutri‑Score algorithm penalises high salt, low protein and modest fiber; this sauce contains about 0.65 g of salt per 100 g (rated high), only 1.7 g of protein and 0.5 g of fiber, which together drive the score down to E despite its low saturated fat.

How might the sugar and salt content of this curry sauce affect a diabetic or hypertensive diet?

At 6.1 g of sugar per 100 g, the sauce contributes a moderate amount of carbohydrates that can raise blood glucose if portions are large, while the high salt level (over 0.6 g per 100 g) exceeds recommended daily limits for hypertension, making it less suitable for people managing diabetes or high blood pressure.

Is this Japanese Katsu Curry suitable for vegan, gluten‑free, or keto diets?

The sauce contains only plant‑based ingredients, so it is technically vegan, but it includes wheat‑based soy sauce and black vinegar, which introduce gluten, making it unsuitable for a gluten‑free diet; its carbohydrate content (13.1 g per 100 g) is also too high for a strict keto regimen.
