Why is Chocolate Negro classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The bar is labeled NOVA 4 because its formulation includes refined grains, added sugars, cocoa paste, multiple emulsifiers, flavorings and stabilizers, all of which involve extensive industrial processing. The declared additives are E476 (polyglycerol polyricinoleate), E320 (tocopherols as antioxidant), E322 (soy lecithin), E420 (sorbitol), E422 (glycerol) and calcium carbonate (E170) used as a stabiliser.

How does the sugar content in this product affect a diabetic diet?

With 28 g of sugar per 100 g, the bar provides a rapid source of glucose that can cause a significant spike in blood‑sugar levels, making it unsuitable for people managing diabetes unless consumed in very small portions and accounted for within their total carbohydrate allowance.

Based on the ingredients, is this product suitable for a gluten‑free or vegan diet?

No. The bar contains whole‑wheat, barley‑derived malt flours and wheat‑based cereals, which introduce gluten, and it also includes milk and soy‑derived ingredients, so it does not meet gluten‑free or vegan criteria.
