膳食蛋白、机体抗氧化调节与健康的关系研究进展

膳食蛋白为机体提供必需氨基酸,还具有广泛的生理功能。膳食蛋白的消化代谢过程中,机体细胞会产生活性氧。活性氧积累可能引发氧化及衰老。细胞中的抗氧化蛋白——硫氧还蛋白、谷氧还蛋白及其他抗氧化酶等共同组成抗氧化系统,抵御活性氧,减少有害物生成。本文综合介绍不同来源的膳食蛋白与相应的抗氧化调节对机体健康的影响,以及活性氧代谢过程中两种抗氧化蛋白的调控作用,结合体内其他抗氧化指标,从而更好地认识不同膳食蛋白的代谢差异,指导个人膳食与健康。 

Research progress in the associations of dietary proteins with antioxidant regulation of the body and human health

Dietary proteins provide the essential amino acids for human body and have a wide range of physiological functions.The cells in vivo can produce reactive oxygen species during dietary protein digestion and metabolism process.The accumulation of reactive oxygen species may lead to oxidation and aging.The antioxidant system including the antioxidant proteins, thioredoxin and glutaredoxin, and other antioxidant enzymes can resist reactive oxygen species and reduce the generetion of harmful substances.The effects of different dietary proteins and the corresponding antioxidant regulation on human health, as well as the regulation of the two antioxidant proteins during reactive oxygen species metabolism combined with other antioxidant indicators were described in this review.The background information is better for us to understand the metabolic differences of different dietary protein and to have a healthy diet.
