Eating Red Meat is Not Natural

Posted on by administrators

Galactose-alpha-1,3-galactose is popularly known as alpha-gal. It is a carbohydrate found in the meat of mammals – exceptions being primates (which includes humans) and other African and Asian apes.

Since the early 2000s, severe allergic reaction has been observed several hours after the consumption of red meat. Several deaths have occurred. This is associated with IgE antibodies to alpha-gal as a result of the patients been bitten by ticks. This has occurred in eastern Australia, south-east USA and Sweden.

BMJ Editorial – Are Some Diets “Mass Murder”?

Posted on by administrators

Richard Smith’s wrote an article Are some diets “mass murder”? in The BMJ on 15 December 2014. He uses a work of a popular commentator to reach his conclusions in this article. Smith’s claim that Nina Teicholz’s The Big Fat Surprise, demolishes the hypothesis that saturated fat is the cause of cardiovascular disease fails with just a little scrutiny.

Deception from The BMJ

Posted on by administrators

On 24th September 2015, BMJ issued a press release titled “BMJ investigation questions expert advice underpinning new US dietary guidelines”. The press release stated:

The expert report underpinning the latest dietary guidelines for Americans fails to reflect much relevant scientific literature in its reviews of crucial topics and therefore risks giving a misleading picture, an investigation by The BMJ has found.

The “BMJ investigation” was an article written by Nina Teicholz in response to the above report. It was not a BMJ investigation. Why is The BMJ press release stating that they, The BMJ, performed an investigation when it is clear that this is not the case.

This article was fully funded with a grant from the Laura and John Arnold Foundation (www.arnoldfoundation.org).

The Laura and John Arnold Foundation provided the seed funding for NuSI, the organisation founded by Gary Taubes and Peter Attia to promote low-carbohydrate nutritional science.

The Ketogenic Disadvantage

Posted on by administrators

Several studies have been published comparing low-carbohydrate, ketogenic diets with low-fat diets, mostly regarding the treatment of diabetes in overweight and obese participants. Prominent researchers in this field are Richard Feinman, Stephen Phinney, Mary Vernon, Jeff Volek, Eric Westman, and William Yancy—all supporters of low-carbohydrate dietary regimes.

Ketosis occurs during starvation. It is not a normal, healthy condition. No animal species or human society normally lives in a state of ketosis. Ketosis occurs when fat in the body is utilized to obtain energy in the absence of glucose. Glucose is normally obtained from the digestion of carbohydrates. Ketosis results in the production of ketones—acetone being one of the three types of ketones produced during ketosis. Blood acidity rises with an increase in ketones.

During pregnancy, ketosis has been linked to adverse outcomes for the unborn child.

Ketogenic diet trials almost invariably compare a ketogenic diet with a mislabeled “low-fat, high-carbohydrate” diet. Both the control diet and the ketogenic diet are not healthy diets—the participants are far from healthy at the start of the trial or at the conclusion.

The ketogenic trials appear to assume that the only criteria for a healthy diet is the ratio of fat, carbohydrate, and protein. Many other components are important for health such as fiber, refined sugars, phytonutrients, and protein sources.

What are the Benefits of a Low-Carbohydrate Diet in Treating Cancer?

Posted on by administrators

The view that sugar causes cancer is prevalent in the popular press and on the internet and it should be avoided.

A number of doctors and naturopaths hold this view. Since starches are digested as simple sugars then it is recommended that starches should also be avoided.

As a result, a low-carbohydrate diet is endorsed. Some ketogenic diets recommend high levels of vegetables which are high in nutrients but low in the amount of energy that is provided. The absence of starch from these diets results in a calorie restricted diet which is possibly ketogenic. If a diet is restricted in carbohydrates, it will be high in fat and protein.

Worried about whether you should be eating eggs?

Posted on by administrators

The Australian Heart Foundation has the following comment regarding eggs.

Worried about whether you should be eating eggs? They’re really nutritious and it’s fine to have them regularly as part of a healthy diet. Eggs contain good quality protein, 11 vitamins and minerals, and are a source of healthy fats including omega-3 fats.
One egg has about 5 g of fat – but most of this is unsaturated, a fat that you need to be healthy. An egg contains only about 1.5 g of saturated fat and no trans fat.
As part of a healthy balanced diet you can eat up to 6 eggs each week without increasing your risk of heart disease.

However, according to the Physicians’ Health Study, doctors consuming 7 or more eggs per week had a 31% increase in all-cause mortality compared with those consuming less than 1 egg per week. With diabetic physicians, the association was much higher with the increase in mortality doubled.

The Big Fat Surprise

Posted on by administrators

An article relating to Nina Teicholz book, The Big Fat Surprise, was printed in the Australian on 29th December 2014. Unfortunately, it is largely a repeat of misinformation and misunderstanding of the history of diet and cardiovascular research that is found in popular books and websites.

Whilst the current western diet is appalling and contributes to our poor health, it is absurd to contend that we have been lied to by the government, nutritionists and researchers. The contention that saturated fat from animals is actually quite good for you and cholesterol isn’t really important is simply wrong and not supported by research.

TIME Magazine Article – Eat Butter – Part 2

Posted on by administrators

TIME magazine published an article by Bryan Walsh that appeared in TIME magazine on 23 June 2014.

The cover of the magazine asserts “Eat Butter. Scientists labeled fat the enemy. Why they were wrong.” Unfortunately, much of the evidence that Walsh presents in the article “Don’t blame the fat” is simply wrong and misleading. Walsh states that between 1977-2012, egg consumption fell 9%, beef 37% and milk 72%.

For the period 1970 – 2000, total added fats (up 40%), dairy products (up 8%), cheese (up 107%), low fat milk (up 79%), all meat products (up 10%), poultry (up 89%) and fish (up 22%) increased. These significant increases were not included in Walsh’s report. All of these food products, even low fat milk, are high fat foods.

 

The total calories consumed also rose significantly by 24%.

TIME Magazine Article – Eat Butter

Posted on by administrators

It is with alarm that I read Bryan Walsh’s article Ending the War on Fat that was published in TIME magazine on 23 June 2014.

According to Walsh:

Keys’ work became the foundation for a body of science implicating fat as a major risk factor for heart disease. The Seven Countries Study has been referenced close to 1 million times.  But Keys’ research had problems from the start.  He cherry-picked his data.

If the book has really been “referenced close to a million times”, it means that it has been referenced close to 80 times every day, including weekends, since the book was published in 1980.

Walsh claims that Keys “cherry-picked” his data.  It is evident that Walsh has confused with Keys’ 1953 paper Keys’ paper, Atherosclerosis, A Problem in Newer Public Health and his later study Seven Countries, A Multivariate Analysis of Death and Coronary Heart Disease.

Walsh fails to elaborate on how Keys “cherry picked” his data. Commencing in 1957, the Seven Countries Study studied 12,763 men in 16 regions in seven countries. What data was omitted from this study? How was the data “cherry-picked”?

What are the Health Benefits of Coconut Oil?

Posted on by administrators

Coconut Oil is passionately advocated as a wonderful product that has a multitude of health benefits.  An example of the potential benefits is shown below.

The health benefits of coconut oil include hair care, skin care, stress relief, cholesterol level maintenance, weight loss, boosted immune system, proper digestion and regulated metabolism. It also provides relief from kidney problems, heart diseases, high blood pressure, diabetes, HIV, and cancer, while helping to improve dental quality and bone strength. These benefits of oil can be attributed to the presence of lauric acid, capric acid and caprylic acid, and their respective properties, such as antimicrobial, antioxidant, anti-fungal, antibacterial and soothing qualities.

It sounds to good to be true.
