UK Docs Advise Adding B12 & Folic Acid to Grains
(NY, Reuters Health, 2002)

In a letter in the Lancet of 1/19/02, researchers at St. James Hospital in Dublin, Ireland advised that, since our bodies need both folic acid (B9) & B12 to dissipate the homocysteine produced when we metabolize proteins, grains should be fortified with both nutrients. Their study demonstrated that folic acid lowered homocysteine, a risk factor for heart attacks; but as they increased folate dosages, homocysteine levels responded less to folates & more to B12.
