I have recently come across data claiming that russet potatoes contain 135 mcg of fluoride per 299 gram serving. Would anyone care to substantiate this? Would this be a catalyst of skeletal fluorosis and brain damage over time(say consuming one such serving per day....for life!). Also I am unsure if Russet poatotoes are really "paleo"...Istumbled across some info claiming they were genetically modified. Would white potatoes be the wiser choice? WHy or why not?

Woah woah woah, remember dose makes the poison. You're talking 0.000045% F by weight, or 0.45 ppm. Something like fluorinated toothpaste is 0.15% F by weight or 1500 ppm. Even taking into account the difference in mass, you're getting 10th the dose of fluorine if you were eating your toothpaste. Fluoride in untreated water can range upwards of 1.5 ppm and you could drink a couple kilos of that per day (3 mg per day).
