Why is Protein Bar Peanut classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The bar contains several industrially derived components such as maltitol (E965) as a sweetener, glycerol (E422) as a humectant, lecithin (E322) as an emulsifier, polydextrose as a bulking agent, and refined cocoa butter and rapeseed oil, all of which are typical of ultra‑processed foods, leading to its NOVA 4 rating.

How does the sugar and saturated fat content in this protein bar affect a diabetic or heart‑health diet?

With only 3.7 g of sugars per 100 g, the bar poses a low glycaemic load and is generally acceptable for people managing diabetes, but its 7 g of saturated fat per 100 g exceeds recommended limits for heart‑healthy diets, so individuals with cardiovascular concerns should consume it only occasionally.

Is Protein Bar Peanut suitable for vegan, keto, or gluten‑free diets?

It is gluten‑free, but it is not vegan because it contains dairy‑based milk protein, whey powder and whole‑milk powder. The high carbohydrate content (35 g per 100 g) makes it unsuitable for a strict keto regimen, though the low sugar level may fit some low‑sugar plans.
