最近幾年，大量研究論文對益生菌的對人體健康，有正面的結論，。，科羅拉多大學博爾德分校首先進行的一項研究表明，多攝取作為腸內益生菌的食物益生元，也可以產生影響，改善睡眠和緩衝壓力的生理影響。 [論文來源] Dietary Prebiotics and Bioactive Milk Fractions Improve NREM Sleep, Enhance REM Sleep Rebound and Attenuate the Stress-Induced Decrease in Diurnal Temperature and Gut Microbial Alpha Diversity. 2017.2 發表於 Frontiers in Behavioral Neuroscience, 2017; 10 DOI:10.3389/fnbeh.2016.00240 益生元是在菊苣，西洋薊，大蒜，韭菜和洋蔥等食物中自然發現的膳食纖維。當益生菌消化益生元纖維時，它們不僅會增加整體的腸道健康，而且會釋放代謝副產物。部份研究認為，這些副產物可以影響大腦功能 綜合生理系博士後研究員羅伯特·湯普森（Robert Thompson）指出：「我們發現攝取益生元可以改善非快速動眼期睡眠，以及在歷經壓力的情況下的快速動眼期睡眠。」 研究人員為3週齡的雄性大鼠餵食了包括益生元在內的標準食物或食物的飲食。然後隨著時間的推移，使用EEG或大腦活動測試來監測大鼠的體溫，腸道細菌和睡眠 - 喚醒週期。 他們發現，益生元飲食中的老鼠花費更多的時間在給大腦休息的非快速動眼期（NREM）的睡眠中，較非食用益生元的對照組比起
