Why does Unsalted Butter receive a Nutri‑Score of E and which nutrients drive this low rating?

The Nutri‑Score algorithm heavily penalises high energy and saturated‑fat levels while rewarding protein, fiber and fruit/vegetable content. Unsalted Butter provides 745 kcal and 49.5 g saturated fat per 100 g, has only 0.7 g protein, no fiber and no fruit or vegetable ingredients, resulting in 19 negative points and zero positive points, which yields a grade of E.

Is the milk allergen in Unsalted Butter a concern for people with dairy allergies?

Yes. The product consists entirely of unsalted butter derived from cow’s milk, and milk is listed as an allergen, so anyone with a cow‑milk allergy should avoid it.

Can Unsalted Butter be included in a ketogenic diet, and is it appropriate for vegan consumers?

The butter’s very high fat content (82 g) and negligible carbs make it compatible with ketogenic macros, but because it is a dairy product it is not suitable for vegans or anyone avoiding animal‑derived ingredients.
