Rediscovering Sweetness: The Evolution and Impact of Non-Nutritive and Natural Sweeteners

Yash Patel et al. Curr Nutr Rep. .

Abstract

Purpose of the review: The escalating incidence of obesity and metabolic syndromes has catalyzed a critical evaluation of dietary sugars, leading to an increased interest in non-nutritive and natural sweeteners as viable alternatives. This manuscript reviews the historical developments, safety profiles, and health-related consequences of these sweeteners, tracing the evolution from early discoveries such as saccharin and cyclamate to contemporary compounds like aspartame, sucralose, and plant-derived sweeteners.

Recent findings: We explore the physiological mechanisms underpinning sweet taste perception, including the roles of T1R and T2R receptors, and the neurochemical pathways involving dopamine in mediating the rewarding effects of sugar consumption. The review underscores the adverse health impacts associated with excessive intake of added sugars, which correlate positively with conditions such as obesity, type 2 diabetes, and cardiovascular diseases. Attention is given to the contrasting profiles of non-nutritive sweeteners and natural sweetener alternatives, with an emphasis on emerging concerns regarding the safety and long-term ramifications of synthetic sweeteners. The regulatory context surrounding the approval and utilization of sweeteners varies significantly across different jurisdictions, warranting careful consideration. As consumer inclination shifts towards healthier dietary choices, a nuanced understanding of the implications of sweetener selection on public health is imperative.

Keywords: Added sugar; Artificial sweeteners; Aspartame; Non-nutritive sweeteners; Saccharin.
