Researchers have known that the brain sends signals to the gut, which is why stress and other emotions can contribute to gastrointestinal symptoms. This study (conducted by scientists with UCLA’s Gail and Gerald Oppenheimer Family Center for Neurobiology of Stress and the Ahmanson–Lovelace Brain Mapping Center at UCLA) shows what has been suspected but until now had been proved only in animal studies: that signals travel the opposite way as well. “ Time and time again, we hear from patients that they never felt depressed or anxious until they started experiencing problems with their gut ,” said Dr Kirsten Tillisch lead author of the study. “Our study shows that the gut–brain connection is a two-way street.” “Many of us have a container of yogurt in our refrigerator that we may eat for enjoyment, for calcium or because we think it might help our health in other ways,” Tillisch said. “ Our findings indicate that some of the contents of yogurt may actually change the way our ...
What's lurking in YOUR salad? Experts warn prewashed spinach still contains 90% of its bacteria and can cause food poisoning
Health experts have warned against eating pre-washed spinach. They say commercial washing techniques fails to remove 90% of the bacteria. Small peaks and valleys in baby spinach leaves could be a key reason why there have been numerous bacterial outbreaks involving leafy green vegetables, they say. Greens are washed by commercial processes before they head to the grocery store. But these methods, which can include water and bleach rinses or irradiation, are not completely effective, says Nichola Kinsinger of the University of California. She says scientists have estimated that 99 percent of food-borne illnesses from leafy greens can be traced back to disinfection issues. 'In a sense the leaf is protecting the bacteria and allowing it to spread,' said Nichola Kinsinger, a post-doctoral researcher working with Sharon Walker, a professor of chemical and environmental engineering. 'It was surprising to discover how the leaf surface formed micro-environments t...
