From Health Correlator: Blood glucose variations in normal individuals are a chaotic mess

“Many people measure their glucose levels throughout the day with portable glucometers, and quite a few are likely to self-diagnose as pre-diabetics when they see something that they think is a “red flag”. Examples are a blood glucose level peaking at 165 mg/dl, or remaining above 120 mg/dl after 2 hours passed since a meal. Another example is a level of 110 mg/dl when they wake up very early to go to work, after several hours of fasting.

As you can see from the picture above, these “red flag” events do occur in young normoglycemic individuals.If seeing “red flags” helps people remove refined carbohydrates and sugars from their diet, then fine.

But it may also cause them unnecessary chronic stress, and stress can kill.”

Sheila Kealey on Turmeric: Healthy or Hype? 

“Although many studies have investigated turmeric/curcumin, and some have shown promise, at this point these findings aren’t good enough evidence to suggest that consuming turmeric improves any health condition.  It’s important to consider the preliminary nature of the research and recent review questioning of curcumin’s biological activity. Turmeric is certainly not a cure-all panacea as some have touted.  More research may help uncover specific benefits to curcumin or other compounds in turmeric.”

How a single high-fat “meal” (palm oil) affects liver metabolism 

I thought we were through demonizing saturated fats.

I put my headline’s “meal” in quotes because the only item in the meal was palm oil. That doesn’t look like one of my meals.

From MNT:

“Individuals who consume higher levels of saturated fats are more likely to feel the effects of a range of health conditions, including non-alcoholic fatty liver disease. Although this link is well-known, exactly how and why it develops is not yet clear.

Recent research investigates the effects of a single high-fat meal on the liver.Non-alcoholic fatty liver disease (NAFLD), as the name suggests, is a condition in which excess fat is stored in the liver of an individual who drinks little or no alcohol.

Marked by liver inflammation, NAFLD most commonly affects people in their 40s and 50s, and especially those who are obese. It can cause scarring of the liver and permanent damage. At its worst, it can lead to liver failure.NAFLD is primarily characterized by an increased buildup of fat in the liver, and this buildup is often accompanied by insulin resistance, thereby increasing the risk of type 2 diabetes and cardiovascular disease.”

German researchers fed a single palm oil meal to 14 healthy men, and some mice.

The article writer doesn’t make it clear whether results apply to the men, the mice, or all combined. Anyway, they found

  • Elevated blood triglycerides
  • Increased glucagon (a pancreas hormone that raises blood sugar)
  • Whole body insulin sensitivity decreased 25 percent
  • Hepatic insulin sensitivity decreased 15 percent
  • Adipose (fat) tissue insulin sensitivity decreased 34 percent
  • Triglycerides in the liver – the main constituent of body fat in humans  – also rose by 35 percent

All of these changes would tend to promote not only NAFLD but also type 2 diabetes.

Whether these adverse changes would be see with other saturated fats or polyunsaturated fats is left unstated in the report.

From UpToDate.com: “The pathogenesis of nonalcoholic fatty liver disease has not been fully elucidated. The most widely supported theory implicates insulin resistance as the key mechanism leading to hepatic steatosis, and perhaps also to steatohepatitis. Others have proposed that a “second hit,” or additional oxidative injury, is required to manifest the necroinflammatory component of steatohepatitis. Hepatic iron, leptin, antioxidant deficiencies, and intestinal bacteria have all been suggested as potential oxidative stressors.”

I’ve been hearing for years that NAFLD is going to be a big deal. At least every other shift I work in the hospital, I see someone with evidence for fatty liver on ultrasound or CT scan.

The mainstay of therapy for NAFLD is weight loss for those who are obese or overweight. It’s probably a good idea to avoid all alcohol consumption, too.

NYT: New Ebola Vaccine Gives 100 Percent Protection 

I don’t know anyone who went into medicine or nursing seriously considering that their job might kill them. So this Ebola vaccine is good news:

“In a scientific triumph that will change the way the world fights a terrifying killer, an experimental Ebola vaccine tested on humans in the waning days of the West African epidemic has been shown to provide 100 percent protection against the lethal disease.

The vaccine has not yet been approved by any regulatory authority, but it is considered so effective that an emergency stockpile of 300,000 doses has already been created for use should an outbreak flare up again.”

Seafood Farmed in China is Tainted with Antibiotics and Bacteria

The problem isn’t the antibiotics per se, but that fact that over-use of antibiotics lead to “super-bugs” (bacteria) that are hard to kill with standard antibiotics in the Western world.

Most of the smoked oyster tins I find in supermarkets in southern Arizona are from China. Now I wonder where the shrimp are from.

From PJMedia.com:

“Imported farm-raised seafood from China is tainted with antibiotics and often salmonella, U.S. regulators say, and the tainted fish is making its way to American tables.

The problem is, Asian fish farmers often supplement their fish feed with feces from pigs and geese, which contain harmful bacteria and antibiotics that have a direct impact on the seafood we eat. According to the latest research, up to 90 percent of the antibiotics administered to pigs pass through their urine and feces.

The U.S. Department of Commerce slapped a 112 percent tariff on Chinese shrimp, effective 2005, but unfortunately, Chinese suppliers have found ways to get around that.”

If Physicians Can’t Comment on Nutrition, Then Exercise, Stress Reduction, and Seatbelts Should Be Off Limits, Too

I’m glad I don’t live in Australia now. Dr. Gary Fettke does, and he got into hot water with the national medical board. We in the U.S. have the 1st Amendment (to our Constitution) that protects free speech.

Dr. Malcolm Kendrick reports:

Anyway, my brain cleared enough to read an e-mail by Gary Fettke, who has promoted the high fat low carb lifestyle for a long time. He, like many others has been ruthlessly attacked for doing this. Professor Tim Noakes was accused of exactly the same thing, and the South African authorities dragged him to court in order to silence him (not yet sure of the verdict).

Gary Fettke is an Australian orthopedic surgeon who has suffered the same fate as Tim Noakes. However, in Australia it seems you can be accused, tried and found guilty without having any chance to defend yourself in person. This is not a court of law, but the Australian Medical Board (AHPRA) who can – as with the General Medical Council (GMC) – strike you off being a doctor. Which for a doctor is a gigantic punishment.

Previously, Gary had been told that he could not comment on any area of nutrition for advocating a reduction in sugar intake (to what are now WHO guidelines). Of course, as with all such cases the ‘authorities’ changed the goalposts from a discussion on low carb high fat (LCHF) and turned the discussion into something else.

Namely, that Gary Fettke, as an orthopaedic surgeon should never give advice on dietary matters. “The fundamental fact ‘is’ that you are not suitably trained or educated as a medical practitioner to be providing advice or recommendations on this topic as a medical practitioner.”

This of course allows the AHPRA to silence him, without discussion any of the science, and no chance of any appeal. So, his suspension about discussing any matters of diet has now been turned into a lifelong ban.
