So, if it's not going to matter either way, I wouldn't worry about it: with two exceptions.

Pernicious anemia is a condition in which the body produces insufficient numbers of red blood cells because the intestines cannot absorb vitamin B12 properly. Vitamin B12 is essential for the production of red blood cells in the bone marrow. This disorder occurs due to low levels of a protein called intrinsic factor, which is released by stomach cells and is necessary for the absorption of vitamin B12 in the intestines. The inability to produce intrinsic factor may be inherited or may arise from an autoimmune process, in which the body’s immune system attacks its own tissues, in this case, the lining of the stomach. Pernicious anemia can also develop from other conditions affecting the stomach lining, such as atrophic gastritis (inflammation and thinning of the stomach lining).
