Fructans are fructose-based oligo-and polysaccharides of natural origin. Fructan and fructose species are sometimes confused by the great public, although they clearly have different biochemical and physiological properties. This review discusses aspects of the use of fructose and fructans in foods in the context of human health, with possible differential effects on cellular autophagy in cells of the human body. Although there are uncertainties on the daily levels of ingested fructose to be considered harmful to human health, there is an emerging consensus on the benefits of the use of fructans in functional foods, sustaining health via direct immunomodulatory and antioxidant effects or through indirect, prebiotic mechanisms.
果聚糖是天然存在的基于果糖的低聚糖和多糖。果聚糖和果糖种类有时会被广大公众混淆，尽管它们显然具有不同的生化和生理特性。本综述讨论了果糖和果聚糖在食品中的使用对人类健康的影响，以及它们对人体细胞自噬可能产生的不同作用。虽然对于每日摄入多少果糖会对人类健康有害尚无定论，但对于在功能性食品中使用果聚糖的益处已逐渐形成共识，即通过直接的免疫调节和抗氧化作用或间接的益生元机制来维持健康。
