Abstract: The present invention relates to the field of nutrition; in particular to the prevention and/or treatment of malnutrition. One embodiment of the present invention relates to a nutritional composition enriched in cysteine for use in the treatment and/or prevention of malnutrition and disorders related thereto. Such a composition may in particular, but not exclusively, be useful for the elderly population.

Abstract: The present invention relates to a method for predicting the risk of acquiring an age-related low-grade inflammation for a subject, said method comprising a) providing a biological sample from a subject, b) determining in said sample the level of at least one biomarker selected from the group consisting of a compound of molecular weight between 859-863 g/mol and which is an alkylacylphosphatidylcholine, a compound of molecular weight between 861-865 g/mol and which is a diacylphosphatidylcholine, a compound of molecular weight between 791-794 g/mol and which is an alkylacylphosphatidylcholine, a compound of molecular weight between 522-525 g/mol and which is a monoacylphosphatidylcholine, octadecanoylcarnitine (C18), and tryptophan, c) comparing the level of the at least one biomarker to a reference level, and d) determining whether said subject is likely to be at risk of acquiring an age-related low-grade inflammation, when the level of biomarker(s) deviate significantly from the respective reference level.

Abstract: A method of improving nutrition and/or treating low grade inflammation in an elderly human subject comprises administering to said subject a cysteine source so as to provide metabolically available cysteine in the diet of said subject in a proportion relative to all available amino acids which is greater that the proportion of cysteine relative to all amino acids which corresponds to the requirements of a healthy young human subject.
