Human beings have a natural craving for sweets. The intensity of this craving varies with genetic and environmental factors; however, excessive use of table sugar has been associated with adverse health outcomes, including increased risk of obesity, diabetes mellitus, and cardiovascular disease. As such, the World Health Organization has called for restricting sugar consumption to less than 5% of total energy intake. For those who have a "sweet tooth," implementing these guidelines is not easy. Hence, the interest in alternative sweeteners. There are eight high-intensity sweeteners that are either approved by the Food and Drug Administration or designated as generally regarded to be safe. The safety of the currently available sweeteners has been questioned. Large cohort studies have reported a positive correlation between sweetener use with weight gain and metabolic risk. A recent meta-analysis, however, concluded that using low- or no-calorie sweetener was associated with small improvements in body weight and cardiometabolic risk factors without evidence of harm. Nevertheless, the World Health Organization advises against the use of nonsugar sweeteners. The biological effects of natural sweeteners such as steviol, monk fruit extract, tagatose, allulose, and sweet proteins (eg, brazzien, miraculin, thaumatin) are not well studied. Eating less sugar is a prudent thing to do, but for people with diabetes mellitus and those at risk of diabetes mellitus, diversifying the type of the sweetener and limiting the quantity may be reasonable.
人类天生喜欢甜食。这种渴望的强烈程度受遗传和环境因素的影响;然而,过量食用食糖与不良健康后果有关,包括肥胖、糖尿病和心血管疾病风险增加。因此,世界卫生组织呼吁将糖的摄入量限制在总能量摄入的 5%以下。对于那些有“嗜甜”习惯的人来说,实施这些指导方针并不容易。因此,人们对替代甜味剂产生了兴趣。有 8 种高强度甜味剂已获得食品和药物管理局的批准或被指定为“一般认为安全”。目前可用的甜味剂的安全性受到质疑。大型队列研究报告称,甜味剂的使用与体重增加和代谢风险之间存在正相关。然而,最近的一项荟萃分析得出的结论是,使用低热量或无热量甜味剂与体重和心血管代谢风险因素略有改善相关,且没有证据表明存在危害。尽管如此,世界卫生组织仍不建议使用非糖甜味剂。甜菊糖、罗汉果提取物、塔格糖、阿洛酮糖和甜蛋白(如 brazzien、 miraculin、thaumatin)等天然甜味剂的生物学效应尚未得到充分研究。少吃糖是明智的做法,但对于糖尿病患者和有患糖尿病风险的人来说,多样化甜味剂的类型并限制其摄入量可能是合理的。
