It is manufactured by the Italian company Ferrero that was first introduced in 1964, although its first iteration dates to 1946. It was originally sold as a solid block, but Ferrero started to sell a creamy version during 1951. Its composition was again modified and it was renamed Nutella in 1964.
Ads highlight the fact that Nutella has no artificial colors or preservatives and it contains, sugar, modified palm oil, and hazelnut, followed by cocoa solids, skimmed milk powder, whey powder, lecithin, and vanillin flavor. In the US, it also contains soy products.
According to its nutritional label, Nutella contains 58% of processed sugar by weight and 10.4 percent of saturated fat. A two-tablespoon (37 gram) serving of Nutella contains 200 calories including 99 calories from 11 grams of fat (3.5g of which are saturated) and 80 calories from 21 grams of sugar. The spread also contains 15 mg of sodium and 2g of protein per serving.
Incidentally, Nutella is marketed as "hazelnut cream" in many countries.
