Energy drinks are rapidly gaining prominence in the global beverage industry, with projected sales reaching $60 billion within the next five years. These beverages often contain high levels of caffeine and the amino acid taurine, among other ingredients. The increasing consumption of energy drinks by children has sparked concerns regarding potential caffeine toxicity. In the present study, an energy drink was administrated at doses of 5 ml/Kg or 10 ml/Kg body weight. The comet assay demonstrated a significant elevation in DNA damage, evidenced by increased % DNA in tail and olive tail moment in the energy drink groups. Additionally, there were notable elevation in malondialdehyde levels as an oxidative stress marker, while reduction in superoxide dismutase activity and glutathione levels as antioxidant markers in energy drink groups. Furthermore, acetylcholinesterase activity and dopamine levels were significantly decrease in the energy drink groups compared to the control group. The high-dose groups exhibited a more pronounced effect than the low-dose groups, indicating a dose-dependent adverse effect.
能量饮料在全球饮料行业中迅速崭露头角,预计未来五年内销售额将达到600亿美元。这些饮料通常含有高浓度的咖啡因和氨基酸牛磺酸等成分。儿童对能量饮料的消费量不断增加,引发了人们对潜在咖啡因毒性的担忧。在本研究中,以5毫升/千克或10毫升/千克体重的剂量给实验对象施用能量饮料。彗星试验表明DNA损伤显著增加,能量饮料组中尾部DNA百分比和橄榄尾矩增加证明了这一点。此外,作为氧化应激标志物的丙二醛水平显著升高,而作为抗氧化标志物的超氧化物歧化酶活性和谷胱甘肽水平在能量饮料组中降低。此外,与对照组相比,能量饮料组的乙酰胆碱酯酶活性和多巴胺水平显著降低。高剂量组比低剂量组表现出更明显的效果,表明存在剂量依赖性不良反应。
