These properties made trehalose a common food additive in [54, 8, 55]: Most manufacturers label trehalose under added sugars or natural flavors.. lightning goddess of death. In healthy and obese mice, trehalose lowered blood insulin spikes and insulin resistance, prevented fat accumulation, and protected the heart from damage [37, 38, 39]. In the lack of clinical evidence, we cant draw any solid conclusions about the nerve-protecting effects of trehalose.
