Nutritional value and environmental aspects of high-protein ultra-processed foods on the German market.

Objective: To compare nutritional value and aspects with environmental impact of high-protein (HP) and 'normal-protein' (NP) ultra-processed foods (UPF).

Design: 299 HP and 286 NP products were evaluated regarding aspects of nutritional value, energy density, Nutri-Score, number of additives as well as hyper-palatability and price. Environmental impact of HP UPF was addressed by analysing protein sources and the use of environmentally persistent non-nutritive artificial sweeteners.
