Before 1980, peanut allergies were rarely mentioned in medical literature or the media, said Miranda Waggoner, a postdoctoral researcher at the Office of Population Research in the Woodrow Wilson School of Public and International Affairs. Her article on the subject, "Parsing the peanut panic: The social life of a contested food allergy epidemic," was published recently in the journal Social Science & Medicine.
Starting around 1990, articles in medical journals began discussing the seriousness of peanut allergies, Waggoner said. At the same time, advocacy groups were emerging to raise awareness of the issue. By the mid-1990s, newspapers were printing articles with headlines such as "Nut Allergy Girl's Terror; Girl Almost Dies from Peanut Allergy."
And the 21st century brought descriptions of peanut allergies — in medical journals and the media — as an epidemic.
For those with a peanut allergy, ingesting the legume can lead to anaphylactic shock and, if untreated, death. But the allergy is quite rare and it isn't clear whether it is becoming more common, Waggoner said.'

'Google's smart contact lens: what it does and how it works
Wearables may be on everyone's list as the major tech trend of the year, but Google just kicked it up to a whole new level. The company announced a project to make a smart contact lens on its official blog Thursday.
But the lens isn't going to be used to deliver your e-mail straight into your skull — at least not yet. This project is working to tackle one of the biggest health problems facing the country today: diabetes.
The soft contact lens that Google's is introducing — it's still just a prototype — houses a sensor between two layers of lenses that measures the glucose levels in tears. The lens also features a small — really small — antenna, capacitor and controller, so that the information gathered from the lens can move from your eye to a device where that data can be read and analyzed.
According to a short explanation of the technology provided by Google, the chip and sensors are mounted on a small plastic-like film. A tiny pinhole in the lens lets tear fluid seep over the glucose monitor to get regular readings. Right now, the company said, it can get a level reading once every second.'
Since when did Google get into the medical devices business?

'Nov. 1, 2013 — Despite current beliefs, sugar intake is not directly associated with nonalcoholic fatty liver disease, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association. Rather, high-calorie diets promote the progression of this serious form of liver disease.
Researchers conducted a double-blind study of healthy, but centrally overweight men to compare the effects of high intakes of two types of sugar, glucose and fructose, in two conditions -- weight-maintaining (moderate-calorie diet) and weight-gaining (high-calorie diet). In the weight-maintaining period, men on neither diet developed any significant changes to the liver. However, in the weight-gaining period, both diets produced equivalent features of nonalcoholic fatty liver disease, including steatosis (fatty liver) and elevated serum transaminase and triglycerides. These findings indicate that fructose and glucose have comparable effects on one's liver, and calorie intake is the factor responsible for the progression of liver disease.
"Based on the results of our study, recommending a low-fructose or low-glycemic diet to prevent nonalcoholic fatty liver disease is unjustified," said Professor Ian A. Macdonald, study author and faculty of medicine and health sciences, University of Nottingham, UK. "The best advice to give a patient is to maintain a healthy lifestyle with diet and exercise. Our study serves as a warning that even short changes in lifestyle can have profound impacts on your liver."'
