Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.


WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

Children eating healthy diets have higher IQs.

Children's Healthy Diets Lead to Healthier IQ

Children fed healthy diets in early age may have a slightly higher IQ, while those on heavier junk food diets may have a slightly reduced IQ

According to new research from the University of Adelaide, led by Public Health researcher Dr Lisa Smithers, the link between the eating habits of children at six months, 15 months and two years, and measured IQ at eight years of age was found to reflect a higher IQ when nutritious foods were being eaten as compared to a 'discretionary' or junk food diet.

The study of more than 7000 children compared a range of dietary patterns, including traditional and contemporary home-prepared food, ready-prepared baby foods, breastfeeding, and 'discretionary' or junk foods.

"Diet supplies the nutrients needed for the development of brain tissues in the first two years of life, and the aim of this study was to look at what impact diet would have on children's IQs," Dr Smithers says.

"We found that children who were breastfed at six months and had a healthy diet regularly including foods such as legumes, cheese, fruit and vegetables at 15 and 24 months, had an IQ up to two points higher by age eight.


"Those children who had a diet regularly
involving biscuits
[cookies], chocolate, sweets,
soft drinks and chips in the first two years of life
had IQs up to two points lower by age eight.


"We also found some negative impact on IQ from ready-prepared baby foods given at six months, but some positive associations when given at 24 months," Dr Smithers says.

Dr Smithers says this study reinforces the need to provide children with healthy foods at a crucial, formative time in their lives.

"While the differences in IQ are not huge, this study provides some of the strongest evidence to date that dietary patterns from six to 24 months have a small but significant effect on IQ at eight years of age," Dr Smithers says.

"It is important that we consider the longer-term impact of the foods we feed our children," she says.

The results of this study have been published online in the European Journal of Epidemiology.
