Une drogue dure comme remède ultime à la dépression ? Lu: Wheat Belly, du docteur William Davis | Ne Cede Malis. Jeudi 26 avril 2012 par jesrad William Davis est un cardiologue qui travaille à la prévention des maladies cardiaques dans le Wisconsin, aux USA. Là où il vit et travaille, les gens ne sont pas juste un peu grassouillets… ils sont énormes, avec facilement 20, 30 ou même 80 kilos de trop. Comme il l’observe parmi ses patients depuis des années, l’obésité et les signes de diabète de type 2 touchent tout le monde sans distinction autour de lui: blancs, noirs, latinos, asiatiques, jeunes, vieux, enfants (et même nourrissons !)
, athlètes, apathiques, célibataires, pères et mères de famille, végétariens ou pas, buveurs d’alcool ou pas, fumeurs ou pas, ça ne fait aucune différence. En plus, c’est un phénomène récent car, sur les innombrables photos que lui ont laissé ses grand-parents, il peut constater la rareté extrême du surpoids, surtout chez les jeunes, dans les deux ou trois générations l’ayant précédé. Un faux ami pour la vie: Like this: J'aime chargement… Pasta, Not Bacon, Makes You Fat. But How? One of the most utterly surprising scientific findings of recent decades has got to be that fat isn’t so bad for you after all. (Apart from, you know, potentially bringing on serious heart conditions.) In fact, if you’re looking for a reason for America’s ballooning girth, you’ve got to lay the blame on carbohydrates--in other words, bread and pasta, the very things that the government once advertised as the foundation of a healthy diet in the food pyramids we all grew up with.
The funny thing is, though, that those low-carb diets, at this point, probably feel like another fad. The Atkins rage came and passed, after all. So it’s worth recounting the science behind how carbs make you fat, and it’s all laid out in this infographic created by Column Five for Massive Health, and based on Why We Get Fat by noted science writer Gary Taubes. The first panel illustrates some basic food science that I’ll bet you didn’t know in much detail. The biggest culprits seem to be carbs. 10 Stubborn Food Myths That Just Won't Die, Debunked by Science. Josh Le, University Of Alberta Student, Wears Same Pair Of Jeans For 15 Months. Walking May Increase Brain Size and Boost Memory. Sitting for hours can shave years off life. More employers are providing adjustable stand/sit workstations and treadmill desks, above, which run at low walking speeds.
Women, men who sat for long periods of time more likely to die in study than those who didn'tIn other surveys, extended periods of sitting increased risks of illnessRecent research shows exercise can't undo damage to health from extended sitting Researchers say public health guidelines should address both physical activity and inactivity (CNN) -- Sitting too much will probably shorten your life. That might sound ridiculous -- or obvious -- depending on your perspective, but the findings don't come from a fringe study. They come from the American Cancer Society, whose researchers studied 123,216 people's health outcomes during a 14-year period.
In particular, the American Cancer Society study finds that women who sit for more than six hours a day were about 40% more likely to die during the course of the study than those who sat fewer than three hours per day. How Many Hours of Sleep Do You Really Need? - Lifehacker. I took a class taught by the Penn PI cited in this article, Dr. David Dinges, called "Human Chronobiology and Sleep". I also worked part-time for a company for which he was a consultant while I was a student.
He's brilliant, truly one of the world's top authorities on sleep, with an extremely impressive, 112 page CV: [www.med.upenn.edu] One thing he emphasized in his class that really stood out for me is the inverse relationship between exposure to light (especially short-wave/blue light around 470nm) and melatonin production. If you're exposed to light (i.e. from a TV, computer, phone, etc) right before you try to sleep, melatonin production is inhibited, and it's going to be very difficult to fall asleep.
Limiting light within a couple hours of when I want to sleep has helped me enormously achieve and maintain a healthy sleep schedule. EDIT: If anyone's interested, here's the syllabus for the course I mentioned: [www.sas.upenn.edu] How Little Sleep Can You Get Away With? Stem cell setback as mice reject own tissue - health - 13 May 2011. Editorial: "Keep stem cell options open" Hopes that people might one day be given transplants made from their own cells have been dashed by experiments trying out the same procedure in mice. The mice rejected transplants of stem cells even though they had been generated from skin cells genetically identical to their own. The surprise finding casts doubt on claims that so-called induced pluripotent stem cells generated from a person's own tissue will ever be medically useful.
Ever since Shinya Yamanaka at Kyoto University in Japan made iPS cells by reprogramming skin cells in 2006, scientists have hoped that the technique could be used to generate transplantable tissue from an individual's own cells . However, the new experiments show that mice recognise many of the reprogrammed cells as foreign and reject them.
"In the context of human therapy, we can't assume that these iPS cells will be immuno-tolerated," says Yang Xu at the University of California in San Diego, head of the team. The Budweiser diet: How long can you survive on beer alone? - By Jeremy Singer-Vine. An Iowa man completed his Lent-long beer fast on Sunday, marking the occasion with a bacon smoothie. During the 46-day feat, J. Wilson consumed only beer and water, emulating a centuries-old tradition once practiced by the Paulaner monks of Munich, Germany. How long could a man survive on beer and water? Not more than a few months, probably. That's when the worst effects of scurvy and protein deficiency would kick in. (Liver disease is a serious risk of chronic alcohol use, but it takes longer to arrive.)
If you kept to a strict beer diet—and swore off plain water altogether—you'd likely die of dehydration in a matter of days or weeks, depending on the strength and volume of beer consumed. Scurvy would be an ironic cause of death for a beer-dieter, since the drink was long considered a prophylactic against the disease. Aside from vitamin C, beer is notably deficient in vitamins A, D, E, and K, as well as thiamine, protein, and fat. Got a question about today's news?
