Why is the Sourdough bloomer classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

It is labelled NOVA 4 because it uses refined wheat flour, fermentation steps and added minerals such as calcium carbonate, iron, niacin and thiamin, which are considered processing aids even though no synthetic additives are listed.

How does the sugar and salt content in this product affect a diabetic or hypertensive diet?

The loaf’s sugar level is low (2.2 g per 100 g), making it acceptable for diabetic meal plans, but its salt (0.9 g per 100 g) is moderate and should be counted toward daily limits for people managing hypertension.

Based on its ingredients, is the Sourdough bloomer suitable for vegan, keto, or gluten‑free diets?

The bread is vegan as all listed ingredients are plant‑derived, but it contains wheat and rye flour, so it is not gluten‑free, and its high carbohydrate content (45.5 g per 100 g) makes it unsuitable for a strict keto diet.
