Is eating lemons unhealthy for someone with Iron Deficiency Anemia?

I’m pretty skinny for my age and I have iron deficiency anemia. I love eating lemons but whenever i do my mom yells at me saying that it sucks the iron out of my blood and makes me skinny?
Is this true? Is eating too many lemons unhealthy?
