Carrageenan in formula and infant baboon development.

Male and female infant baboons were reared from birth to 112 days of age on infant formulas containing concentrations of carrageenan varying from none to 5 times the concentration in commercially available formulas for human infants. Carrageenan content of the formula did not affect weight, characteristics of urine and feces, findinds on physical examination, hematological variables, blood chemical analyses, organ system weights, or the macroscopic and microscopic appearance of the gastrointestinal tract.
