I think there are a lot of theoretical harms that simply don't pan out in  
real life and this is one of them unless of course one ate a weird diet of  
nothing but raw nuts. But if one is that worried, I would simply avoid them  
altogether -- but that's just me and my robust lazy streak.

The  point is they are high 
in phytic acid, and phytic acid strongly binds to  minerals like 
calcium, iron, zinc and magnesium to form insoluble salts,  phytates. 
This decreases the absorption of these minerals. One solution is  to 
consume your phytic acid in a meal separate from your consumption of  
these minerals.
