On this examine, scientists have investigated the affiliation between protein consumption and wholesome getting old in middle-aged nurses residing in the USA.
Research design
The examine was performed on a complete of 48,762 feminine nurses whose age was under 60 years in 1984. The members have been chosen from the Nurses’ Well being Research (NHS), established in 1976, with 121,700 registered feminine nurses aged 30–55 years at enrollment. Life-style practices and medical historical past of the members have been recorded at baseline and each two years thereafter.
