• Animal and Plant Protein – Leucine and Telomeres

  Leucine is an amino acid that is much more prevalent in animal-based diets than plant-based diets. The leucine is found in the high concentrations, measured in grams per kCal of energy, in beef (0.021), egg white (0.021), isolated soy protein (0.020), poultry (0.018) fish (0.018), spirulina (0.017), lamb (0.014) parmesan cheese (0.010), tofu (0.008), soy beans (0.007).

  Leucine is fed to animals in longevity and geriatric research to increase the rate of aging.

  Aglets are the caps on shoelaces that stop them from unraveling. Our chromosomes have telomeres that perform the same function - they stop our chromosomes from unravelling. The longer they are, the longer the cells survive and the longer we live. An animal-based diet results in shorter telomeres than those on a plant-base diet. Leucine is the amino acid responsible for this.

• 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 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.

• Where do You Get Your Protein

  “Where do you get your protein?” (or iron of calcium) is a frequent question for those on a vegan diet. Well, the same place as gorillas, elephants, the grumpy extinct aurochs, brontosaurus and Argentinosaurus- the largest ever land animal weighing more than 15 elephants. From eating plants.

  Milks are complex lipid emulsions in water containing protein, fat, lactose, vitamins and minerals, as well as enzymes, hormones and immunoglobulins which provide initial immunity functions.

  There is approximately 5,500 species of mammals which initially supply their young with milk. There are vast differences in milk composition among the mammal species. Of all the mammals, humans have the lowest protein content.

  Mammals have evolved over millions of years to provide nutrition for their infants in the first stage of life. There are significant difference between species depending upon factors such as rates of growth.

  Proteins in human milk provide sufficient of protein to sustain infants for the first six months without any additional food, as well as supplying the means of establishing suitable environment for the growth of healthy intestinal bacteria and providing the proteins involved in the immune system.

• Methionine Dependent Cancers

  Homocysteine is a non-protein amino acid. It is synthesized in the body from methionine, which is a sulfur containing amino-acid.

  Methionine is much more prevalent in animal products than plant products. Rotten eggs smell the way they do because the sulfur produces a number of sulfur containing gases including hydrogen sulfide— rotten egg gas.

  A high level is of homocysteine is associated with an increased risk for chronic inflammation, cardiovascular disease, and Alzheimer’s disease.

  Many human cancer cell and primary tumors have a requirement for methionine, an essential amino acid.

  Methionine-free or methionine-deprived diet causes a regression of a variety of animal tumours.

• 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.

• 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 vocal critic of soy.

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

  The US Department of Agriculture has an extensive database of the nutrient constituents of over 8,000 foods. The amount of protein, carbohydrates, fibre and fat in food can be accessed as well as the individual fatty acids, amino acids, minerals and vitamins.

  There are also many other resources including research data and information regarding the food intake of US citizens.
