芬兰奥卢大学的研究发现，经常饮用咖啡的人尽管体重指数（BMI）相近，但脂肪含量更少、骨骼肌质量更高，同时代谢标志物也更加健康1。这项研究分析了北芬兰出生队列1966年组的2264名46岁参与者，揭示了咖啡摄入与身体代谢的密切关联1。
研究结果显示，高咖啡摄入与总体脂肪和内脏脂肪水平的降低相关联1。在激素水平方面，咖啡摄入对男性和女性产生了不同影响：男性高咖啡消费者的睾酮和性激素结合球蛋白（SHBG）水平均升高1，而女性则表现为SHBG升高但游离雄激素降低1。此外，高咖啡摄入还与支链氨基酸水平降低和葡萄糖-胰岛素代谢谱系改善相关1。
研究作者卢卡·维罗斯特表示："咖啡与我们的代谢和激素如何相关，我们仍然知之甚少"1。这项研究已发表在《欧洲营养学杂志》2026年第65卷第5期1。
A study from the University of Oulu in Finland has revealed that regular coffee consumers have less body fat, greater muscle mass, and healthier metabolic markers compared to those with low coffee intake, despite having similar BMI levels.1 Researchers analyzed 2,264 participants aged 46 from the Northern Finland Birth Cohort of 1966, examining associations between coffee consumption and various physiological measures.1
The findings showed that higher coffee intake was linked to lower total fat and visceral fat, as well as increased skeletal muscle mass.1 Additionally, increased coffee consumption correlated with lower levels of branched-chain amino acids and improved glucose-insulin profiles.1 Sex hormone differences also emerged between high and low coffee consumers: men with higher coffee intake showed elevated testosterone and sex hormone-binding globulin (SHBG) levels, while women demonstrated increased SHBG alongside decreased free androgens.1
The research, published in the European Journal of Nutrition Volume 65, Issue 5 in 2026, provides new insights into coffee's metabolic effects.1 Study author Luca Verroest noted that "we still know very little about how coffee relates to our metabolism and hormones."1 The findings are particularly relevant given that residents of Finland consume approximately 11.8 kilograms (26 pounds) of coffee per capita annually.1
