What does DHA, egg yolks, baby foods, research, and a patent application have
in common? Nope-no patridge in a pear tree. HM...let's think about it. Yep
you got it! Eileen Birch and Dennis R. Hoffman. Birch and Hoffman have done
the research that has been somewhat instrumental in the current drive for DHA
in infant formula. Now we can have it in our baby foods through the use of
egg yolks (particularly eggs from chickens who are fed a DHA-supplemented diet
of marine algae brought to you by Martek). We have to salute these researchers
for their creative vision and business acuity. Valerie W. McClain, IBCLC

"[0006] DHA in an infant's diet promotes visual development and leads to
enhanced visual acuity. DHA can be provided to breast-fed infants through their
mother's milk, which contains a full-complement of both .omega.-6 and .omega.-3
polyunsaturated fatty acids (Hoffman et al, 1993, supra; Makrides et al.,
1995, supra; Innis et al, Am. J Clin. Nutr 60:347-352, 1994). The concentration of
DHA in breast milk can, however, vary depending upon the mother's diet and in
addition, many infants are not breast-fed or are breast-fed only for a few
weeks and must rely on infant formula and solid baby food for their nutritional
requirements. In the past, infant formulas sold in the United States have not
contained DHA (Jensen et al., J. Pediatr. 131:200-209, 1997). Nevertheless,
feeding an infant a formula supplemented with DHA and arachidonic acid after
weaning from breast feeding, has been shown to improve visual acuity (see Birch
et al, Am. J. Clin. Nutr 75:570-580, 2002; Hoffman et al., J. Pediatr.
142:669-677, 2003). Semi-solid foods fed to babies have little or no DHA. Intake of
fat from such solid foods does not increase plasma DHA levels as does breast
feeding (Luukkainen et al., J. Pediatr. Gastroenterol. Nutr. 23: 229-234, 1996)."
