carotene in sweet potatoes?

Answered on August 19, 2014
Created October 05, 2012 at 10:02 PM

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?

thks!

Thanks, yes, I've read all that, & many, many other pages on iodine supplementation. But all of those are written by people who are recommending high dose iodine therapy, and they seem to blame every single side effect on bromide detox. Not sure I really care what it is...if you read long enough, you'll find people who ended up with serious long term thyroid problems. I might think it was worth the risk if I had breast cancer, but since I don't, it is not worth the risk to me! Obviously it works well for some people, but I don't think I'm one of them.

take a look here for a long list of just some 'Iodine-related bromide symptoms' http://breastcancerchoices.org/bromidedetoxsymptomsandstrategies.html & it includes cherry angiomas

thx Robin. i've never heard of 'cherry angiomas' before, just did a google image, i think i may have a few. also googled things like 'angiomas iodine bromine'. It looks like they may related to bromine toxicity (& iodine deficiency). & iodine can detox bromine.

...saw my doc, had thyroid tests (normal) and then thyroid ultrasound (some hot nodes, but they thought all benign). After about 10-12 weeks, finally felt "normal" again. I had no idea how easily iodine evaporated from table salt, and also had started using sea salt for cooking more, so I think I was possibly deficient before this whole experience & that made me react more severely to iodine than expected? Don't know, but now I'm being very careful & replacing salt in the shakers more frequently, paying closer attention to how often I have seafood, etc. But not going to try supplements again.

I started very cautiously (about 50 mcg a day, which you wouldn't think would do anything much), but never got past 150 mcg a day -> had a breakout of cherry angiomas on my torso, some hair loss, metallic taste in my mouth. Decided I did not want to mess with it and would stick with what I got from salt & seafood. A couple months later, ran out of salt, bought new iodized salt, and within a week I had symptoms of hyperthyroid: hungry and eating all the time but lost weight (that part was nice!), more serious hair loss (not so nice), and general feeling of being anxious & shaky. So...

Hi Robin, if you don't mind me asking, what was the full story with your iodine experiment. i'm a bit wary of iodine myself, but i do take iodine drops (iosol) now & then. thx

^BBF- No, I do not believe you can get excess retinol from beta carotene, and that is just the reason you start turning orange (as a benign way of doing away with excess beta carotene once retinol stores are replete).

Alligator, you honestly think that you can get "excess vitamin A" from beta-carotene conversion? No. That will never happen in a million years. Beta-carotene is useless as a source of Vitamin A. When retinoic acid is not produced from retinol or beta-carotene, it gets deposited in the skin as beta-carotene which itself is orangey-red. Topical accutane/retin-a works in a similar way, except the retinoid is tretinoin instead of beta-carotene.

Actually, i believe you are both correct. ie. your body will not convert carotene to retinol if you are retinol replete. But some peoples conversion of beta-carotene into retinol may be impaired; possible causes for this may be liver disease, hypothyroidism & diabetes (there are others listed in the links in my answer). So you could be retinol deplete & still turn yellow, in this situation better to get retinol from animal food sources (no need to convert).

BoneBrothFast is incorrect. It is actually the case that you have already converted enough beta carotene to retinol, and any further conversion would result in excess retinol. The orange pigmentation is the result of beta carotene build up AFTER retinol requirements have been met.

The yellow-skin is called Carotenosis and it's harmless, it just means you suck at converting Beta-Carotene into retinol (the goal of carotene consumption.)

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.
