Feds eye update to key food guidelines

Staff Report

FRISCO — Conservation activists say that a recent round of comments and petitioning by the public show growing support for a more sustainable federal dietary guidelines, with a shift toward more plant-based food

At issue is a proposal by the U.S. Department of Health and Human Services to update those guidelines based on the recommendations of a science committee that recommended the changes. Continue reading

Long-term research tracks structural brain changes in young children exposed to PAHs

Staff Report

FRISCO — Prenatal exposure to common pollutants from auto emissions, power plants and other sources may be a big factor in the rising tide of behavioral disorders in children, researchers say.

After tracking 40 children from before birth until 7 to 9 years of age, the researchers say they found a powerful link between exposure to PAHs and disturbances in parts of the brain that support information processing and behavioral control.  Continue reading

Can federal guidelines help Americans choose a healthier diet?

Staff Report

FRISCO — Guided by an advisory panel, federal health experts last week set the stage to nudge American consumers toward a more sustainable diet that’s higher in plant-based foods and lighter on animal-based foods.

In the long-term, the changes would improve individual health and result in a smaller environmental footprint, according to panel, which submitted its recommendations to the U.S. Department of Health and Human Services and the U.S. Department of Agriculture.

The new scientific report spelled out the fundamental realities of diet and health. About half of all American adults — 117 million individuals — have one or more preventable, chronic diseases, and about two-thirds of U.S. adults — nearly 155 million individuals — are overweight or obese, patterns that have persisted for more than 20 years.

Climate change will shift the world’s disease zones.

Staff Report

FRISCO — Global warming is likely to hasten the spread of infectious diseases to new geographic areas and new host species, scientists warned in a recent study, urging health experts to think ahead as they consider the effects of various pathogens on plants, animals and humans.

“We have to admit we’re not winning the war against emerging diseases,” said Daniel Brooks, a zoologist with the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln. “We’re not anticipating them. We’re not paying attention to their basic biology, where they might come from and the potential for new pathogens to be introduced.” Continue reading

New study links decline of bees with malnutrition, especially in developing countries

Staff Report

FRISCO — Declines of crucial crop pollinators like bees is likely to put huge numbers of people in developing countries at risk for malnutrition, according to a new study that bolsters links between ecosystem stability and human health.

The research by scientists at the University of Vermont and Harvard University tested the claim that pollinators are crucial for human nutritional health by connecting what people actually eat in four developing countries to the pollination requirements of the crops that provide their food and nutrients.

Exposure to fine particulate air pollution during late pregnancy increases risk of autism.

Findings could open the door for preventive measures

Staff Report

FRISCO — Harvard public health researchers say evidence is growing that exposure to high levels of air pollution during pregnancy may double the risk of having a child with autism. The study was the first to explore the link between airborne particulate matter and autism. Continue reading
