About 2 months ago, a study came out in the British Medical Journal claiming that breast milk had no effect on infant brain development and intelligence.

Just read an article on WebMD that discusses new research out of the University of Florida.

The study, published in The Journal of Pediatrics, reveals that children who are obese by age 4 are more likely to have lower IQ scores.

Specifically, children that weigh 150% more than their ideal weight had IQ scores that were 25-30 points lower.
