Your hemoglobin is quite low (8.5), so this is significant anemia and should not be managed by diet alone. MCV is slightly high, which can be seen with
Vitamin B12/folate deficiency or other causes, so further evaluation is needed.
Please consult a physician soon and get tests like serum B12, folate, iron profile/
ferritin, reticulocyte count and peripheral smear correlation. Depending on the cause, you may need medicines/supplements and not just dietary changes.
Do not panic, because WBC and platelet counts are normal, but anemia at this level should be properly evaluated and treated rather than ignored.
