Harvard Researchers Paid to Support Sugar

A recent story that has been appearing on the internet is that Harvard Researchers Paid to Support Sugar and this is the reason why sugar and carbohydrates have been exonerated in their role of causing heart disease. Fats and saturated fats have unfairly blamed for the obesity and heart disease epidemic.

The article states that, "Early warning signals of the coronary heart disease (CHD) risk of sugar (sucrose) emerged in the 1950s."

"By the 1960s, 2 prominent physiologists were championing divergent causal hypotheses of CHD: John Yudkin identified added sugars as the primary agent, while Ancel Keys identified total fat, saturated fat, and dietary cholesterol. However, by the 1980s, few scientists believed that added sugars played a significant role in CHD, and the first 1980 Dietary Guidelines for Americans [4] focused on reducing total fat, saturated fat, and dietary cholesterol for CHD prevention."

Rural Indian Regional Diets

Despite India's reputation for a healthy, vegetarian cuisine, it is not justified. Only 1.6% of Indians are vegan, 24% are lacto-vegetarian. 3% add eggs to their lacto-vegetarian diet which leaves 72% consuming meat.

The Indian population has the highest prevalence of diabetes worldwide and exhibits high-risk metabolic profiles at younger ages and lower body mass index than their Western counterparts. There are significant regional variations to this observation.

The reasons why Asian populations exhibit diabetes at a lower threshold than western populations are not known.

According to WHO mortality statistics, India is ranked 17 for Low Birth Rate, 37 for Diarrhoeal Diseases, 40 for Tuberculosis, 60 for Malnutrition and 62 for Influenza & Pneumonia out of 183 countries.

Given the current increase in consumption of meat and oils and a decrease in grains, the prevalence of obesity and diabetes is likely to continue.

Global Burden of Disease 2010

The Global Burden of Disease Study commenced in 1990 as a World Bank commissioned initiative that measures the health impact of disease and injuries. It introduced the term disability-adjusted life year (DALY) as a new measure to quantify the burden of diseases and injuries.

It is managed by the Institute for Health Metrics and Evaluation at the University of Washington with the purpose of "understanding the current state of population health and the strategies necessary to improve it."

How do Your Genes Affect Obesity and Diabetes

The purpose of the DIETFITS Trial was "to determine the effect of a healthy low-fat (HLF) diet vs a healthy low-carbohydrate (HLC) diet on weight change and if genotype pattern or insulin secretion are related to the dietary effects on weight loss".

It a popular area of research to determine if there are genetic causes of obesity, diabetes, heart disease, autoimmune disease, depression and any other illness or condition that is plaguing our society.

This area of research ignores the fact that often our genetics does not determine health outcomes. Ignoring this will not solve the problems of our society's rapidly failing health.

The conclusions of this paper are:

In the 12-month study, there was NO significant difference in weight change between a healthy low-fat diet compared with a healthy low-carbohydrate diet.

Neither of the 2 hypothesized predisposing factors [genotypes] was helpful in identifying which diet was better for whom.

Frequently the problem is not that complicated.

Letter to Diggers – October 2018

In the Spring 2018 edition of Diggers, Bel P claims that What The Health has been “expertly torn to pieces”. No effort has been made to justify this claim. What The Health web site has listed approximately 300 references for the movie with the elapsed time that the information was presented.

In the absence of a valid critique of What The Health, I will present some evidence presented by the movie for the health benefits of a whole-food, plant-based diet. All references provided are from primary sources for which I have the paper or electronic copy.

Michael Mosley and Coconut Oil

Dr Michael Mosely (Trust Me, I’m a Doctor) instigated a trial to determine the impact of coconut oil on cardio-vascular health.

In a University of Cambridge study, 94 participants were randomly assigned to one of three groups. They were asked to consume an additional 50g of fat – either coconut oil, butter or olive oil, daily for a period of four weeks.

The main measure was the change in total cholesterol.

Based on this study, Michael Mosley now thinks that coconut oil may be good for you. The study showed nothing to suggest that this could be true.

DASH Diet and Blood Pressure

The concept that diet and blood pressure are linked has been discussed since at least the 1920s. In 1926, Donaldson noted that “vegetarians, we believe, run a consistently lower blood pressure than those who use flesh foods."

MRFIT Study – What did it tell us?

The Australian Broadcaster ABC televised the program Heart of the Matter Part 1 - Dietary Villains on Thursday, 24 October 2013. This program listed the MRFIT study as more evidence that cholesterol is not implicated in heart disease.

The Multiple Risk Factor Intervention Trial (MRFIT) was a coronary heart disease prevention trial that was conducted at 22 US clinical centres (18 cities) from 1973 to 1982. The multiple risks evaluated were elevated serum cholesterol, elevated blood pressure and cigarette smoking.

A number of popular commentators use this trial as proof that cholesterol is not implicated in heart disease.

The tobacco industry also used the results of the MRFIT study to argue that smoking is not harmful.
