Need ideas for what to eat during treatment

I'll be starting quadruple therapy (pylera + PPI) in a couple of days. The instructions say "do not take dairy products, calcium, iron, magnesium, zinc ... within 2 hours of this drug."

I understand what this means in terms of dairy ... but how do you find food that has zero calcium, iron, or magnesium?? Eggs, chicken, black beans, canned tuna, nuts, bread, and many fruits/veggies have iron and/or calcium.

What do you all eat during these 14 days??
