Children's nutritional intake shown to impact IQs

While this comes laregly from a bird study (so you can say it is for the birds if you so desire), the results are so important that I will join the others in making the jump to applying it to human development.

From Science Daily:

"Poor nutrition early in life can impair neural development, leading to lower IQ in humans and flawed song learning in birds. Recent evidence indicates that many organisms can offset some of the changes associated with early poor nutrition by modifying their physical development. For example, poorly nourished children can undergo a period of accelerated growth once their diet improves, ultimately appearing normal as an adult. But such compensatory measures may come at a price, with cognitive or other developmental disabilities emerging later in life"
