Aspartame (APM) is a dipeptide sweetener (L-aspartyl-L-phenylalanine methyl ester). It has been suggested that excessive use of the product might elevate plasma aspartate and phenylalanine concentrations. Eight normal adults (four male, four female) ingested three successive 12-oz servings of APM-sweetened beverage at two-hour intervals. The study was(More)
Total mercury concentration was measured by atomic absorption spectrophotometry in 100 maternal-umbilical cord blood pairs, 39 placentae, and 32 breast milk samples, all from patients at the University of Iowa Hospitals. The mean maternal and cord blood levels were 1.01 and 1.24 parts per billion (ppb), respectively. Though the difference between maternal(More)
This review evaluates scientific data associated with the possibility that trans fatty acids compromise fetal and infant early development. Concerns have been triggered by research that has heightened our awareness of the importance of n-3 and n-6 fatty acids; shown that trans fatty acids inhibit delta6 desaturation of linoleic acid; identified trans fatty(More)
Blood methanol concentrations were measured in 24 1-year-old infants administered aspartame, a dipeptide methyl ester sweetener. The doses studied included a dose projected to be the 99th percentile of daily ingestion for adults (34 mg/kg body weight), a very high use dose (50 mg/kg body weight) and a dose considered to be in the abuse range (100 mg/kg body(More)
Vitamin E (alpha-tocopherol) has been credited with a variety of beneficial effects in the premature newborn infant. It has been thought that deficiency of vitamin E is at least partly responsible for the anemia which often occurs 4 to 6 wk after premature birth, and routine dietary supplementation with vitamin E is frequently recommended. However, critical(More)
