After working as a Neonatal Intensive Care Unit dietitian, I moved to Houston and began to work with Dr. Abrams in July 2001. Currently, I manage the dietary components of our local and international studies. I have also had the opportunity to travel to Central and South American countries to give lectures and hands-on education to physicians, nurses, and nutritionists on the nutritional management of premature babies.

I am a past president of the Houston Area Dietetic Association (HADA). With almost 400 members, this is the largest district association in the state of Texas. I am also proud to have served as the Texas Dietetic Association (TDA) Legislative and Public Policy chair for Federal Issues.

Books

Abrams SA, Hawthorne KM. Bone Health in Children. CRC Press, Boca Raton, Florida, 2012.

Bone health is one of the most widely discussed topics in pediatric nutrition. Ensuring adequate calcium and vitamin D intake is essential, and other factors also play a significant role. Bone Health in Children explores the recent decades of research and public commentary on the subject, debunks popular myths, and clarifies the often confusing and contradictory scientific literature. Presenting practical and theoretical education and advice, the book provides rational and accessible information geared to a wide audience of individuals interested in this critical element of pediatric health.

Highlights include:

  • The Institute of Medicine process by which Dietary Reference Intakes (DRIs) are developed
  • Iron, calcium, and vitamin D requirements for infants, children, & pregnant and lactating women
  • Controversy over high-dose vitamin D supplementation and pregnancy
  • Detailed explanation of the scientific research process related to human nutrition
  • The non-bone health aspects of vitamin D & why literature claims about this topic can be misleading
  • Frequently Asked Questions regarding nutrition with answers in short format
