sorry to bug y'all but i thought the paleo hack community could really help me out with this one. since i im trying to build muscle, i made sweet potatoes one of my main carb source to gain weight and bulk up and its been like this for a few months now(i consume them on workout days only) and alot of poeple told me i had yellow ish looking hands. the other day, it clicked in my mind! i thought it might be the the sweet potatoes.
anybody else noticed something similar? what is a good tasty tuber alternative? is it considered somewhat dangerous?

Yes, you can start turning yellow if you over do your intake of carotenoids (from foods &/or supplements).
This is known by a few names, ie. carotenosis, carotenaemia, carotenemia, xanthaemia, carotenodermia It usually appears first on the palms and soles of your feet (starting with the calluses).
another link here with info and some photos.
btw, impaired conversion of beta-carotene into retinol is known as secondary carotenaemia/carotenoderma, see here for possible causes.
& if you start turning orange, it could be Lycopenodermia
"High intakes of lycopene-rich foods or supplements may result in a deep orange discoloration of the skin known as lycopenodermia. Because lycopene is more intensely colored than the carotenes, lycopenodermia may occur at lower doses than carotenodermia"

Just wanted to note that other things, like excess iodine intake or other thyroid function issues, can cause carotenosis as a side effect, as daz points out above. It might be worth considering whether or not you've got other issues, and this is just a sign. So in other words, if you stop eating sweet potatoes and it goes away, I would not assume you've necessarily taken care of your problem.
I had some serious thyroid issues after a short experiment with very low dose iodine supplementation, and my hands turned yellow too...mostly visible in sunlight or fluorescent light.
