Aggressive and violent behaviors are restrained by self-control. Self-control consumes a lot of glucose in the brain, suggesting that low glucose and poor glucose metabolism are linked to aggression and violence. Four studies tested this hypothesis. Study 1 found that participants who consumed a glucose beverage behaved less aggressively than did participants who consumed a placebo beverage. Study 2 found an indirect relationship between diabetes (a disorder marked by low glucose levels and poor glucose metabolism) and aggressiveness through low self-control. Study 3 found that states with high diabetes rates also had high violent crime rates. Study 4 found that countries with high rates of glucose-6-phosphate dehydrogenase deficiency (a metabolic disorder related to low glucose levels) also had higher killings rates, both war related and non-war related. All four studies suggest that a spoonful of sugar helps aggressive and violent behaviors go down.
攻击性和暴力行为受到自我控制的约束。自我控制会消耗大脑中的大量葡萄糖，这表明低血糖和不良的葡萄糖代谢与攻击性和暴力行为有关。四项研究检验了这一假设。研究 1 发现，饮用葡萄糖饮料的参与者比饮用安慰剂饮料的参与者表现出的攻击性要弱。研究 2 通过低自我控制发现，糖尿病（一种以低血糖和不良葡萄糖代谢为特征的疾病）与攻击性之间存在间接关系。研究 3 发现，糖尿病发病率高的州暴力犯罪率也高。研究 4 发现，葡萄糖-6-磷酸脱氢酶缺乏症（一种与低血糖有关的代谢紊乱）发病率高的国家，无论是战争相关还是非战争相关的杀人率都更高。这四项研究都表明，一勺糖有助于抑制攻击性和暴力行为。
