• 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.

• 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.
