Many popular ideas in relation to amino acid requirements have been influenced by evidence regarding their impact upon growth rather than health and longevity.
Cancer can be seen as a disease of excessive growth, and requirements for the ‘essential’ amino acids tryptophan and cysteine decrease as we reach adulthood.
Gelatin is free of tryptophan, has only small amounts of other inflammatory amino acids, and is a great source of the protective amino acids, in particular glycine.
Excess tryptophan and cysteine inhibit thyroid function and metabolism – promoting inflammation and the release of polyunsaturated fats from storage – whereas glycine is generally pro-metabolic.
Polyunsaturated fats cause further inflammation, increasing levels of the cytokines, including tumor necrosis factor (TNF), nitric oxide (NO) and the prostaglandins, promoting growth hormone and tumor development.
Glycine, proline and alanine – all found in large amounts in gelatin – are cytoprotective, anti-inflammatory and inhibit growth hormone release.
Glycine promotes healing and inhibits the growth of tumors, and the excessive formation of blood vessels common in cancer.
“In vivo treatment with glycine blocks tumor growth and artery formation in tumors…Therefore, glycine can be used not only for treatment of inflammation, but also for chemoprevention and treatment of carcinoma.”
Balancing amino acids with glycine or gelatin generally protects against stress, fibrosis, free radical damage, inflammation and disease.
Glycine inhibits the release of the polyunsaturated fats and cortisol – and protects against the damaging effects of endotoxin – reducing insulin resistance and the symptoms of diabetes.
And glycine directly protects against the cancer promoting effects of the polyunsaturated fats.
Glycine also helps recovery from stroke, and reduces symptoms of MS, schizophrenia and arthritis.
Dietary glycine – sometimes consumed from a gelatinous beef broth – also protects against all types of inflammatory bowel disease.
Consuming sufficient sugar – in the form of sweet ripe fruits or juices, honey, milk and simple white sugar – and balancing your protein intake with gelatin – or supplemental glycine – will help to protect against the multi faceted disease and inflammation promoting effects of the stress hormones such as cortisol, serotonin, prolactin, growth hormone and more.
Restricting intake of foods high in tryptophan, cysteine and methionine – whilst also increasing intake of glycine – is one useful approach to protection against disease and aging in general.
“Dietary methionine (Met) restriction (MR) extends lifespan in rodents by 30–40%…We propose that more efficient Met clearance…with GS [glycine supplementation] could be reducing chronic Met toxicity…”
