Vitamin D supplements protect against acute respiratory infections including colds and flu, according to a study led by Queen Mary University of London (QMUL). The study provides the most robust evidence yet that vitamin D has benefits beyond bone and muscle health, and could have major implications for public health policy, including the fortification of […]
Chemical compound found in essential oils improves wound healing
Indiana University researchers have discovered that a chemical compound found in essential oils improves the healing process in mice when it is topically applied to a skin wound — a finding that could lead to improved treatments for skin injuries in humans. IU scientists also reported that skin tissue treated with the chemical compound, beta-carophyllene […]
BPA levels in humans dramatically underestimated, study finds
Researchers have developed a more accurate method of measuring bisphenol A (BPA) levels in humans and found that exposure to the endocrine-disrupting chemical is far higher than previously assumed. The study, published in the journal The Lancet Diabetes & Endocrinology on Dec. 5, provides the first evidence that the measurements relied upon by regulatory agencies, including the […]
Light pollution can suppress melatonin production in humans and animals
Melatonin sets the internal clock. Researchers from Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in an international team have analyzed data on the impact of light pollution on melatonin formation in humans and vertebrates. They found that even the low light intensities of urban skyglow can suppress melatonin production. Melatonin synchronizes the day-night-rhythm in […]
Consumption of licorice can lead to dangerously high blood pressure and dangerously low potassium levels
As it turns out, you really can overdose on candy—or, more precisely, black licorice. Days before the biggest candy eating holiday of the year, the Food and Drug Administration (FDA) encourages moderation if you enjoy snacking on the old fashioned favorite. So, if you’re getting your stash ready for Halloween, here’s some advice from FDA: […]
Endocrine disruptors in soy products
On the basis of a laboratory test on soy products, revealing particularly worrying levels of phytoestrogens, compounds strongly suspected to be endocrine disruptors, the UFC-Que Choisir seizes the ANSES and the DGCCRF to enhance safety and information on food products containing them. In the meantime, the Association is making recommendations to consumers to limit their exposure […]
Photoinitiators detected in human breast milk
Photoinitators (PIs) are compounds used in the ink of many types of food packaging. The substances have been shown to migrate into food and, when consumed, show up in human blood serum. Now, for the first time, researchers report they have detected PIs in human breast milk, although they say the levels consumed by breastfeeding […]
Ketogenic diet helps tame flu virus
A high-fat, low-carbohydrate diet like the Keto regimen has its fans, but influenza apparently isn’t one of them. Mice fed a ketogenic diet were better able to combat the flu virus than mice fed food high in carbohydrates, according to a new Yale University study published Nov. 15 in the journal Science Immunology. The ketogenic diet […]
Microplastics found in oysters, clams on Oregon coast
Tiny threads of plastics are showing up in Pacific oysters and razor clams along the Oregon coast — and the yoga pants, fleece jackets, and sweat-wicking clothing that Pacific Northwesterners love to wear are a source of that pollution, according to a new Portland State University study. Britta Baechler, a Ph.D. student in PSU’s Earth, […]
Too much ultra-processed food linked to lower heart health
Researchers at the U.S. Centers for Disease Control and Prevention (CDC) found that for every 5% increase in calories from ultra-processed foods a person ate, there was a corresponding decrease in overall cardiovascular health. Adults who ate approximately 70% of their calories from ultra-processed foods were half as likely to have “ideal” cardiovascular health, as […]
