Folic Acid

Baroness Bull Excerpts

Thursday 3rd September 2020 Lords Chamber

[Baroness Bull (CB)]

My Lords, the 2006 SACN report Folate and Disease Prevention found that there was insufficient human data to say conclusively whether increased levels of blood folate from fortification might impact on the efficacy of anti-folate medication, which acts in chemotherapy by blocking the action of folic acid. The 2017 update is silent on this issue. Can the Minister clarify whether the absence of a reference to this issue is because there is still insufficient data, or is it because research has ruled out any adverse impact of mandatory fortification on those patients taking anti-folate medication?

[Lord Bethell (Con)]

My Lords, I am not aware of any conclusive scientific evidence that contradicts the benefits of folic acid. As I said, the demographic data would seem to suggest that experiences in other countries have been benign. Longitudinal studies take a very long time to emerge and, therefore, we are not expecting a massive change in that data. However, back at the department, I will ask if any science has emerged and I will write to the noble Baroness if I can put my hands on anything.
