Animal and Plant Protein – Lysine and Arginine

Lysine is an indispensable dietary amino acid for all vertebrates and is required for protein synthesis.

The arginine requirement is influenced by many factors that vary between species. There is an antagonism that can occur between lysine and arginine in some species where excessive intakes of one of these amino acids will adversely affect the metabolism of the other amino acid thereby increasing its requirement.

Lysine is a dietary indispensable amino acid.

Lysine is the first limiting amino acid in most grain and cereal-based diets so it also defines the protein required to meet the amino acid requirements..

Human milk is supplied to babies when the need for protein is at the greatest. Babies double in size during the first 6 months of our lives. The ideal food for a baby is mum’s milk where 5% – 6.5% is protein. This should offer reassurance that as long as we a consuming an adequate diet, we do not need a high protein diet.

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."

Robert Lustig and The Men Who Made Us Fat

Robert Lustig is a pediatric endocrinologist at the University of California, San Francisco. He is the author of Fat Chance: Beating the Odds against Sugar, Processed Food, Obesity, and Disease. He specializes in childhood obesity and studying the effects of sugar in the diet. He is the director of the UCSF Weight Assessment for Teen and Child Health Program and a member of the Obesity Task Force of the Endocrine Society.

Unfortunately, much of what he says is simply wrong, which given the amount of media exposure that he receives, is deeply worrying.

The A2 Milk Story

The hypothesis that A2 milk was protective of type 1 diabetes originated with a paper published in 1992. Robert Elliott observed much lower rates of type 1 diabetes amongst Polynesian children that were raised on the Polynesian islands compared with those raised in Auckland. This was attributed to the differences in the β-casein profile.

Elliott was the lead author of a conference paper that examined the effects of feeding casein to non-obese diabetic (NOD) mice. The conclusion was that “the induction of diabetes by casein in the NOD mouse appears to be restricted to casein containing the A1 variant of beta-casein”.

The marketing potential of such a discovery could be enormous.

CSIRO Low-Carb Diets

The CSIRO Low-Carb Diet and CSIRO Total Wellbeing Diet were developed in Australia by the CSIRO.

The CSIRO Total Wellbeing Diet plan "is higher in protein, and lower in high Glycemic Index carbohydrates which supports weight loss, especially fat mass whilst helping with appetite control".

The CSIRO Low Carb Diet is "lower in carbohydrate and higher in healthy fats which may improve blood glucose control and possibly a reduction in need for diabetes medication".

The CSIRO Diets DO NOT improve blood glucose control and DOES NOT reduce the need for diabetes medication.

The Truth About Soy Myth

A widely distributed article Tragedy and Hype : Third International Soy Symposium written by Sally Fallon and Mary G. Enig in March 2000 documents a series of issues relating to soy consumption.

They claim that “Soy is the next asbestos”, that it contains “anti-nutrients”, causes dementia and Alzheimer’s disease, reproductive problems and much more.

The book The Whole Soy Story: The Dark Side of America's Favorite Health Food is written by Kaayla Daniel. Sally Fallon was the editor of the book.

According to the book,

Soy is not a health food, does not prevent disease and has not even been proven safe. Epidemiological, clinical and laboratory studies link soy to malnutrition, digestive problems, thyroid dysfunction, cognitive decline, reproductive disorders, even heart disease and cancer.

Sally Fallon and Mary Enig are co-founders in 1999 of the Weston A Price Foundation. Kaayla Daniel is also a board member of the Weston A Price Foundation. Joseph Mercola, a board member of Weston A Price foundation, is another strong critic of soy.

The longest lived people on earth are from the Okinawa archipelago in southern Japan who consume large amounts of soy products.
