I think PUFA can be a problem if consumed in an extreme excess, but as for me I haven’t noticed any problems with it. I’m not consuming it each and every meal I have, but I’m not afraid of having some in my diet. Plenty of healthy people consume PUFAs to some degree. So yes, I’m not going to base my diet around them but I’m also not going to worry about having a few nuts or nut butters here and there. I do recommend macadamia nuts, however. They are full of monounsaturated fats, and they taste great!
