Lead in the Blood Lowers Test Scores

University of Michigan School of Public Health researchers led by Nanhua Zhang found that higher levels of lead lowered test scores, even when grade level, gender, race, language, maternal education and socioeconomic status were all figured in. The CDC recently lowered the acceptable level from 10 to 5 mcg/dl. Not too long ago the normal level was 20. In reality, coauthor Michael Elliot stated, “there is no well-documented threshold for acceptable levels of lead in the body.” Children and adults accumulate lead from products made in China and from the food supply. Both should be tested and treated, if needed. Poor mental abilities are just the tip of the iceberg. Various chronic degenerative diseases such as heart disease, cancer, and autoimmune problems have also been linked to minimally elevated levels of lead.
