Alzheimer's May Be Linked to Normal Diet Byproduct

The article starts out:

People with high blood levels of a normal diet byproduct, homocysteine,
have twice the average risk of developing Alzheimer's disease, a study
being published today finds.

The study suggests that other major degenerative diseases like
cardiovascular disease and diabetes may stem at least in part from diet,
possibly making them preventable.

Then includes:

Homocysteine is an amino acid, a building block of proteins. Its levels can
rise when people eat a diet heavy in animal protein and few fruits or leafy
vegetables. Fruits and vegetables can lower the levels by providing B
vitamins, folic acid and vitamins B6 and B12, which help convert
homocysteine to other amino acids that are not harmful.

Now it looks to me that Denise Grady thinks that B12 comes from fruits and
vegetables. Just shows how biased she is, that she simply assumes that this
is yet another pro vegetarian article that she's reporting on.
