Selenium deficiency promoted by climate change
February 21, 2017 10:08 AM - ETH Zurich

As a result of climate change, concentrations of the trace element selenium in soils are likely to decrease. Because the selenium content of crops may also be reduced, the risk of selenium deficiency could be increased in many regions of the world. This was shown by a recent study which used data-mining to model the global distribution of selenium.

Selenium is an essential micronutrient obtained from dietary sources such as cereals. The selenium content of foodstuffs largely depends on concentrations in the soil: previous studies have shown that low selenium concentrations are associated with high pH and oxygen availability and low clay and soil organic carbon content. In Europe, as is known from regional studies, selenium-poor soils are found particularly in Germany, Denmark, Scotland, Finland and certain Balkan countries.

The Dangers Behind Fast Food Packaging

Susan Bird, Care2

We’ve all known for a long time that eating fast food is bad for you. It’s greasy, fatty, high in sodium and the calorie count is obscene. Now comes news that even the packaging that food comes in might be dangerous to your health.

A new study found dangerous chemical compounds in almost half of the 400 fast food containers it tested from 27 fast food franchises. Packaging tested in this study came from the Big Four: McDonald’s, Chipotle Mexican Grill, Starbucks and Yum! Brands, Inc., which operates Taco Bell, KFC, Pizza Hut and WingStreet.

The substances in question are perfluorinated chemicals (PFCs). That’s the same stuff that once was used to make Dupont’s Teflon before it had to be removed from the market. It’s also used in carpeting, furniture, clothing and cosmetics because of its water-repellant and stain-resistant qualities. We’re exposed to it every day.
