Overly Clean Homes Can Increase Child’s Risk of Asthma, Allergies
Living in an overly clean home can actually increase an infant’s risk of developing allergies or asthma as they grow older, as their bodies are not given the chance to develop appropriate responses, according to a new study in the Journal of Allergy and Clinical Immunology. The researchers behind the study were surprised by the results, as they had been looking deeper into data that found that exposure to roach, mouse and pet droppings and other allergens increased asthma risk. "What we found was somewhat surprising and somewhat contradictory to our original predictions," said study co-author Robert Wood, MD, chief of the Division of Allergy and Immunology at the Johns Hopkins Children's Center in Baltimore, according to HealthDay. "It turned out to be completely opposite—the more of those three allergens you were exposed to, the less likely you were to go on to have wheezing or allergy." Approximately 40 percent of the allergy- and wheeze-free children in the study were raised in homes with high amounts of allergens and bacteria, while only 8 percent who suffered from both conditions had been exposed to allergens and bacteria while infants.

Study: Prenatal Medicaid Policy Reduces Smoking, But Doesn’t Improve Preterm Birthweights
While a Medicaid policy that fast-tracks applications of pregnant women helps reduce smoking during pregnancy, it has no significant effect on improving preterm birth rates or low birth weights, according to a new study in the journal Health Affairs. The study specifically looked at Medicaid’s presumptive eligibility and unborn-child option, which provides coverage for prenatal care. “Although the prevalence of prenatal smoking in the United States has declined in recent decades, it is nearly twice as high among low-income women enrolled in Medicaid than it is in the U.S. population as a whole,” said Marian Jarlenski, PhD, lead author of the paper. “Our research shows that Medicaid’s presumptive eligibility policy led to a nearly 8 percentage-point decrease in smoking during pregnancy, but neither policy significantly improved rates of preterm birth or babies born small for their gestational age.” Read more on maternal and infant health.
CDC: Watercress Tops ‘Powerhouse’ Fruits and Vegetables List
With a “nutrient density score” or 100.00, watercress tops the U.S. Centers for Disease Control and Prevention’s (CDC) new list of “powerhouse” fruits and vegetables. The list of 41 foods was created as a tool for nutrition education and dietary guidance. The study defined “powerhouse” as foods most strongly associated with reduced chronic disease risk, which are often green leafy, yellow/orange, citrus and cruciferous items. Chinese cabbage, chard, beet green and spinach rounded out the top five. The full list is available here. Read more on nutrition.
