Need a good reason to convince you to buy organic milk? It’s just plain healthier, according a study by Newcastle University.

Cows on organic farms that are allowed to graze as nature intended are producing better quality milk that contains significantly higher beneficial fatty acids, antioxidants and vitamins than their conventional “high input” counterparts, says the university in a press release. During the summer months, when the cows are grazing on fresh grass in the fields one of the beneficial fats in particular – conjugated linoleic acid, or CLA9 – was found to be 60% higher.

“We have known for some time that what cows are fed has a big influence on milk quality,” said Gillian Butler of the Nafferton Ecological Farming Group at Newcastle University, who led the study in the release.

“What is different about this research is it clearly shows that on organic farms, letting cows graze naturally, using forage-based diet, is the most important reason for the differences in the composition between organic and conventional milk. Read more

Diesel fumes may damage your brain

A team of Dutch researchers did an experiment to test the effects of exposure to diesel fumes on the brain by putting 10 volunteers into a room filled with exhaust from a diesel engine for one hour, reports Reuters. The volunteers’ brain waves were monitored with an EEG. The level of fumes was similar to that found on a busy road or in a garage. After about 30 minutes, the brain wave patterns displayed a stress response, which suggests changes in information processing in the brain cortex. More research is needed to determine the clinical effect of this stress and whether it has any long-term effects. Previous studies have found very small particles of soot are able to travel from the nose and lodge in the brain.

Broccoli found to hold immunity-boosting chemical

brocollinew.jpgResearchers think that a chemical in broccoli and other cruciferous vegetables, such as cabbages and radishes, may hold a key to restoring the body’s immune system, which weakens as we get older. Scientists at UCLA found that sulforaphane, a chemical in broccoli, switches on a set of antioxidant genes and enzymes in specific immune cells in the body. These cells then combat the harmful effects of molecules known as free radicals that can damage cells and lead to disease. So eat your brocolli! Read more at ScienceDaily
