Food makers will be required by federal law to use the labels, starting in 2020. The safety of genetically modified ingredients, widely known as G.M.O.s, remains a source of anxiety for some Americans despite the scientific studies that say they pose no health threat. Many food makers now voluntarily place “No G.M.O.’’ labels on their products as a marketing tactic. Clarifying how genes are altered in the plants and animals we eat, and whether grocery store shoppers should care, has proved to be a heavy lift. But here are a few answers to questions about the proposed labels. What is a G.M.O.? The term stands for “genetically modified … [Read more...] about G.M.O. Foods Will Soon Require Labels.

LAS VEGAS — One of the latest additions to the healthcare industry’s long list of conferences this week brought together prominent thought leaders and investors to discuss a myriad of health innovation topics — from value-based care to vertical integration. With an emoji-forward market presence, HLTH 2018 planners (who also created Shoptalk and Money20/20) pulled together a speaker lineup that read like a list of who’s who in the digital health space, including CEOs from athenahealth, 23andMe, Allscripts and Fitbit, to name a few. Geisinger CEO David Feinberg, Change Healthcare and former CMS Administrator Andy Slavitt all made major announcements during their time on stage, and senior leadership from Walmart and CVS Health showed up to deliver their respective takes on the healthcare industry. With the inaugural conference in the books, Healthcare Dive pulled together the highlights. Walmart's announcement was kind of a snooze Walmart was set up to make a large … [Read more...] about What was and wasn’t said at HLTH 2018
Biology textbooks may be due for a rewrite.For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.The tangled shape, known as an i-motif, had been seen before in the lab, but few researchers expected it to occur in human cells.The new work shows not only that i-motifs do indeed exist in human cells, but that they may be quite common.“Our imaging suggests that this is a normal thing that happens,” said Marcel Dinger, a molecular biologist at the Garvan Institute for Medical Research in Sydney, Australia, who oversaw the research. “It is very likely that genomes in all the cells of our bodies are forming i-motifs at some point in time.”A report on the find was published Monday in Nature Chemistry.The study lends credence to the idea that these unusual DNA shapes may play an essential role in human biology, said Laurence Hurley, a … [Read more...] about In human cells, scientists find DNA that looks like a twisted knot instead of a double helix
Could the no-calorie sweetener you rely on to replace sugar in your diet actually cause weight gain instead of the weight loss you were expecting?The answer may be yes, according to a new study."Artificial sweeteners are not risk-free," said Brian Hoffmann, assistant professor in the Department of Biomedical Engineering at the Medical College of Wisconsin and Marquette University, and a lead author of the study. "They are a very controversial topic when it comes to health and nutrition ... but they're so prevalent in society that I think we owe it to ourselves to try and figure out what's actually going on."Hoffmann presented his new research Sunday at the annual Experimental Biology meeting in San Diego. Relying on rats and human cell cultures, his team identified a number of pathways linking artificial sweeteners with metabolic changes at the genetic level that could lead to diabetes and obesity. Specifically, the researchers found that three weeks of exposure to … [Read more...] about Artificial sweeteners: Where do we stand?
Genetic testing is all the rage these days. Some tests can reveal serious health scenarios, such as if you're predisposed to cancer or Alzheimer's disease. Other tests purport to tell you how much Neanderthal DNA is still in your bloodstream. But can genetic screening also tell if you're predisposed to cabernet?A group of doctors-turned-entrepreneurs started a company called Vinome to answer this question. Vinome, based in Healdsburg, Calif., is one of a handful of startups applying DNA analysis to discover what you'll like and dislike in food and drink. Consumers who sign up for Vinome fill out a survey inquiring into their general food and wine preferences, and mail in a saliva sample to Vinome's genetic testing firm.A few weeks later, Vinome provides a picture-filled report with catchy turns of phrase about what your DNA says you'll enjoy. Maybe you didn't know that you were a "Jam Dunk" someone who likes rich, jammy wines or a "Bing is King," whose palate appreciates cherry and … [Read more...] about Are you predisposed to pinot noir?
