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

The bar receives a NOVA 4 rating because its ingredients are industrially refined and include isolated proteins, soluble corn fiber, and sweeteners; the formula contains additives such as lecithin (E322), erythritol (E968), and stevia glycosides (E960) that are typical of highly processed foods.

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

With only about 3 g of sugars per 100 g, the bar is relatively low-sugar compared with most snack bars, which can help regulate blood glucose, but it still provides 0.6 g of salt per 100 g, a level that may contribute to sodium intake and should be limited for people managing hypertension.

Based on its ingredient list, is this protein bar suitable for gluten-free, vegan, keto, or kosher diets?

The product is certified gluten-free and bears the Orthodox Union kosher seal, but it contains milk-protein isolate and whey-protein isolate, so it is not vegan; its carbohydrate content (≈38 g per 100 g) is too high for a strict ketogenic diet, making it appropriate only for gluten-free and kosher consumers.
