Abstract
Abstract The apoptosis of CD4 cells in a person infected with the human immunodeficiency virus may be impeded by enterally feeding to the infected person a nutritional product which contains soy protein hydrolysate having a degree of hydrolysis in the range of about 14 to 17 and a molecular weight partition, as determined by size exclusion chromatography, wherein 30%-60% of the particles have a molecular weight in the range of 1500-5000 Daltons. The nutritional product also contains a source of intact protein. The nutritional product has a ratio, by weight, of n-6 to n-3 fatty acids of about 1.3:1 to 2.5:1. The nutritional product also contains a source of dietary fiber.
