• 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).

  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 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.

• Comparison of Dairy Milks with Human Milk

  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.

  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.

• 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 gasses 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.

• What is a Heart Attack?

  Below is an overview of the mechanism that leads to cardiac myocardial infarctions (or heart attack). It took many decades for a basic understanding of this process.

  The consensus at the beginning of the 20th century was that heart disease is a normal part of aging. In 1913, a 28 year old pathologist, Nikolay Anitschkow (or Anichkov), working at the Military Medical Academy in St. Petersburg, showed that by feeding rabbits cholesterol dissolved in sunflower oil induced vascular lesions closely resembling those of human atherosclerosis, both grossly and microscopically. Controls fed only the sunflower oil showed no lesions.

  Another difficulty in understanding heart disease is that there are a number of factors involved. Researchers, practitioners and the public become attached to one aspect. Some argue passionately regarding one aspect of heart disease and become blind to other factors.

• To alkalise your body – what does it mean?

  A number of books and websites tells us we need to alkalise our bodies for optimal health. What does this mean? Is alkaline water a scam or does it really have health benefits?
