Vegan and vegetarian diets increase risk of a stroke compared to eating meat, study finds

INTRO: University of Oxford study found 20 per cent higher rates of stroke in vegetarians and vegans than in meat eaters. Vegan and vegetarian diets could increase the risk of a stroke, according to new research. A University of Oxford study found 20 per cent higher rates of stroke in vegetarians and vegans than in meat eaters, equivalent to three more cases of stroke per 1,000 people over 10 years. This was mostly due to a higher rate of haemorrhagic stroke – the type caused by bleeding in or around the brain. The researchers said the increased risk of stroke could be down to lower levels of vitamins among the vegetarians and vegans in the study and called for further investigations. They also suggested that low blood levels of total cholesterol among vegetarians and vegans may play a role. (MORE)
Do names shape the way we categorise what we perceive?

EXCERPT: The unusual side effect of a stroke has given French neurologists a rare opportunity to study the interaction between language and thought. A male patient identified only as RDS discovered that while he could identify something as red, blue, green, or any other chromatic hue, he could not name the object's colour. [...] Before his stroke, RDS perceived and named colours normally. After the stroke, an MRI revealed a lesion in the left region of his brain, which apparently severed his memory of colour names from his visual perception of colours and his language system.
Yet he could still group most colours – even those he couldn't name – into categories such as dark or light or as being a mixture of other colours. "We were surprised by his ability to consistently name so-called achromatic colours such as black, white, and grey, as opposed to his impaired naming of chromatic ones such as red, blue, and green," says first author Katarzyna Siuda-Krzywicka. “This suggested that our language system may process black, white, and grey differently from chromatic colours. Such striking dissociations raise important questions about how different colour-related signals are segregated and integrated in the brain.” (MORE)
