• Egg Consumption, B12, Lutein and Zeaxanthin

  B12 is a group of cobalt-containing vitamins. Hydroxocobalamin and cyanocobalamin are synthetic forms of vitamin B12. The two forms of vitamin B12 naturally occurring in foods are methylcobalamin and adenosylcobalamin. These forms are biologically equivalent.

  B12 is produced by a number of different species of bacteria which is found in the soil, on the surface of some plants and some red and green algae.

  Lack of vitamin B12 can have serious consequences as does high levels of homocysteine. Determining the status of vitamin B12 and homocysteine can be difficult and can be determined by measuring serum vitamin B12, homocysteine and methylmalonic acid (MMA).

  A number of products contain riboflavin, pyridoxine, folate, B12 and methionine way in excess of dietary requirements in an attempt to resolve B12 metabolism problems.

  Many magnesium supplements contain pyridoxine which is usually unnecessary and possibly detrimental.

  Vitamin B12 is not made by plants or animals but by microbes. In today’s world, the water supply is commonly chlorinated to kill bacteria. We don’t get much B12 in the water, we also do not get much cholera.

• 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.
