Feds Spend $1.5 Million to Study Why Lesbians Are Fat

For every dollar spent on this, we borrow 40¢ that will have to be paid back by the taxpayers.  This is so crazy, I question whether the story is even accurate.  A snippet:

The National Institutes of Health (NIH) has awarded $1.5 million to study biological and social factors for why “three-quarters” of lesbians are obese and why gay males are not, calling it an issue of “high public-health significance.”

You Career Women, If You Want Babies, Better Not Put It Off Too Long

See this graph on age-related fertility at Mangan’s Breviary.  To both have a busy career and raise babies, I wonder if it’s best to have the babies in early adulthood, putting off career moves, if necessary, until later.

Pressuring Your Doctor For a Z-Pak May Kill You

…if she prescribes it and doesn’t know you have:

  • low blood levels of magnesium or potassium
  • heart rate below 60, or
  • QT prolongation

Details are at MedPageToday.

Remember, virus infections don’t respond to antibiotics that suppress bacterial infections.  Bronchitis, for example, is often a viral infection.  Sinusitis usually gets better without antibiotics.

Your Expensive Heart Drug May Be a Waste of Money

…according to an article at MedPageToday.  Specific brands of extended-release niacin and fibrates are mentioned, among others.  I particularly like this quote of Dr. James Stein:

“So at least $4.5 billion was spent on drugs with uncertain benefit and known risks,” Stein said. “I’d much rather these patients focus on exercising and eating a healthy, Mediterranean-based diet, which has been proved to reduce heart attacks and strokes, than spending money on these agents.”

It’s a good idea to talk to the prescribing physician before stopping any of your drugs. 

Does Diet Affect Age-Related Memory Loss and Dementia Risk?

Don’t wait to take action until it’s too late

High blood insulin levels and insulin resistance promote age-related degeneration of the brain, leading to memory loss and dementia according to Robert Krikorian, Ph.D.  He’s a professor in the Department of Psychiatry and Behavioral Neuroscience, University of Cincinnati Academic Health Center.  He has an article in a recent issue of Current Psychiatry – Online.

Proper insulin signaling in the brain is important for healthy functioning of our brains’ memory centers.  This signaling breaks down in the setting of insulin resistance and the associated high insulin levels.  Dr. Krikorian makes much of the fact that high insulin levels and insulin resistance are closely tied to obesity.  He writes that:

Waist circumference of ≥100 cm (39 inches) is a sensitive, specific, and independent predictor of hyperinsulinemia for men and women and a stronger predictor than body mass index, waist-to-hip ratio, and other measures of body fat.

Take-Home Points

Dr. Krikorian thinks that dietary approaches to the prevention of dementia are effective yet underutilized.  He mentions reduction of insulin levels by restricting calories or a ketogenic diet: they’ve been linked with improved memory in middle-aged and older adults.

Dr. K suggests the following measures to prevent dementia and memory loss:

  • eliminate high-glycemic foods like processed carbohydrates and sweets
  • replace high-glycemic foods with fruits and vegetables (the higher polyphenol intake may help by itself)
  • certain polyphenols, such as those found in berries, may be particularly helpful in improving brain metabolic function
  • keep your waist size under 39 inches, or aim for that if you’re overweight

I must mention that many, perhaps most, dementia experts are not as confident  as Dr. Krikorian that these dietary changes are effective.  I think they are, to a degree.

The Mediterranean diet is high in fruits and vegetables and relatively low-glycemic.  It’s usually mentioned by experts as the diet that may prevent dementia and slow its progression.

I’ve written before about how blood sugars in the upper normal range are linked to brain degeneration.  Dr. Krikorian’s recommendations would tend to keep blood sugar levels in the lower end of the normal range.

Do You Know How To Perfectly Poach an Egg?

I don’t – never even tried.  Darya Pino found a video showing how to do it with a fine mesh strainer.

Israeli President Shimon Peres Eats a Mediterranean Diet

Brief details are here.  Peres is 89, BTW.  He seems to prefer low-fat dairy when he eats dairy.  Probably no particular need for that unless you’re watching your weight (calories).

Jonny Bowden, Ph.D., Disputes That Mediterranean Diet is the Best

From his article at the Huffington Post: 

My own personal opinion is you could design a dozen diet studies showing the superiority of a dozen different diets (from Atkins to Ornish to the Zone) as long as you compare each of them to the crap we’re eating now.

Read the rest.

As for Dr. Bowden’s repeated claim that there’s no specific Mediterranean diet, here’s one!  It’s as specific as any other mainstream named diet out there.

 

Fred Hahn Says Two Weekly Seesions of Weight Training Are Optimal

…in general.  See his recent blog post.  A snippet:

 “…2 weekly training sessions produced significantly better gains in lean weight than one session a week (3lbs. vs. <1lbs.) and better losses in fat mass.  Note that three strength sessions a week did not produce better gains in lean tissue. More exercise is not always better!”

I’m not very familiar with Fred’s exercise ideas, but they sound similar to what I’m doing personally.

For Low Back Pain, Walking Program May Be Just As Good As Clinic-Based Muscle Strengthening

…according to an article at ScienceDaily.  Excerpt:

Dr. Michal Katz-Leurer of Tel Aviv University’s Stanley Steyer School of Health Professions at the Sackler Faculty of Medicine says that a simple aerobic walking program is as effective in alleviating lower back pain as muscle strengthening programs that require specialized equipment in rehabilitation clinics. The program includes walking two to three times a week for a period of 20 to 40 minutes.

Sounds too good to be true, doesn’t it?  You know what they say about that.  Since back pain tends to flare and regress spontaneously, I wonder if an untreated control group would have improved like the two active intervention groups.
