Longer daily fasting times improve health and longevity (in mice)

The scientists randomly divided 292 male mice into two diet groups. One group received a naturally sourced diet that was lower in purified sugars and fat, and higher in protein and fiber than the other diet. The mice in each diet group were then divided into three sub-groups based on how often they had access to food. The first group of mice had access to food around the clock. A second group of mice was fed 30 percent less calories per day than the first group. The third group was meal fed, getting a single meal that added up to the exact number of calories as the round-the-clock group. Both the meal-fed and calorie-restricted mice learned to eat quickly when food was available, resulting in longer daily fasting periods for both groups.

The scientists tracked the mice’s metabolic health through their lifespans until their natural deaths and examined them post-mortem. Meal-fed and calorie-restricted mice showed improvements in overall health, as evidenced by delays in common age-related damage to the liver and other organs, and extended longevity. The calorie-restricted mice also showed significant improvement in fasting glucose and insulin levels compared to the other groups. Interestingly, the researchers found that diet composition had no significant impact on lifespan in the meal fed and calorie restricted groups.

One of my neighbors is a mouse researcher.  I bet he’s really excited this weekend.

What the News Left Out About K2

As a psychiatrist, I have encountered countless individuals in the emergency room who come through and do not want help. “What K2? I don’t use that stuff.” They will deny it, laugh it off, or scoff at me. They threaten to commit suicide if I don’t let them stay the night, and demand extra sandwiches and clothes. These individuals have the ability to decipher their options.  If the person’s thinking suddenly clears and there is no sign of physical instability, he or she can just walk out the emergency room almost minutes after presenting. In the dead of night, I’ve had unconscious patients who wake up abruptly only to demand to leave. I have no choice but to discharge them “home” to no particular address, since none are listed.

Only two percent of teens read newspaper, one-third have not read book for pleasure in last year

“Think about how difficult it must be to read even five pages of an 800-page college textbook when you’ve been used to spending most of your time switching between one digital activity and another in a matter of seconds,” she added. “It really highlights the challenges students and faculty both face in the current era.”

My random thoughts:

  • ADHD
  • Bad parenting
  • Technology addiction
  • Social media is not social
  • Social media is evil
  • The slow agonizing death of newspapers
  • Colleges and universities will be challenged
  • Put the cellphone down and keep your hands where I can see them.

Fewer U.S. teens smoking, doing drugs, and drinking milk

Kids have shifted from a dairy product rich in calcium and vitamin D to beverages laden with sugar and caffeine, which is likely contributing to the nation’s obesity problem, said Barry Popkin, a University of North Carolina researcher who studies how diets change.

“This is not a healthy trend for our long-term health,” he said.

Meat Company Finds Americans Are Afraid of Hot Dogs

Meat brand Applegate finds that 47 percent of consumers are scared to discover the ingredients in hot dogs, while 24 percent of millennials never purchase them.

I find surveys like this amusing.  Interview 1000 people and extrapolate the findings to all Americans.  The click bait title is great too.  It’s so misleading I had to copy it verbatim.
