Blood Test Results

So I got back my blood test results and the doc says it's low iron deficiency. She conducted other tests from the blood tests I provided and everything else was normal, just the iron levels. Also told doc that I ended up having a sudden allergy to fruit and she seemed not too phased by it. She said some of her patients have had that allergy with fruit. My lips just swell or my mouth upper palete starts itching. She said if it's happening frequently (which it has been) to stop eating it... Stop eating fruit? But that's my iron supplement right? Anyway, she said if I continued eating fruit that causes a reaction, it could become problematic. So she suggested vegies as a substitution.
