    Several studies have recently shown antioxidants can promote metastasis in cancer.
    This study is limited by the fact that this research was done on mice. However, because of the results of this study as well as previous research with similar findings, I would think a study with humans would now be considered unethical. See below. Bolding is mine.
    http://www.upi.com/Health_News/2015...e-may-promote-spread-of-cancer/2051445022723/

    The complete study is behind a paywall which for me, leaves some questions unanswered. If anyone has access to the full version, it would be helpful.

    While the title mentions the use of pro oxidents may be beneficial against cancer, from what I can find it looks like this is only inferred from the study. I also could not get a sense if antioxidants in food would have the same effect as supplements. Supplements are an easier way to consume higher doses of antioxidants as well as metabolized differently. But does that make a difference?

    Unfortunately, cancer cells start developing before it's discovered and some of these people may be taking high doses of antioxidant supplements.

    I really do not like the generalising in these kinds of articles, the lack of specific information is terrible journalism and leads one to believe its more fear mongering towards supplements, which we see all the time. Antioxidants is just such a broad term and the mechanisms and activity of different 'antioxidants' is clearly not going to be the same.

    My understanding in this study it relates to NAC (n-acetyl cysteine)? Saw this story a few days ago and think that is what it said.

    Edit: Just adding a comment I found relating to NAC and this study.

    @GhostGum

    I agree. The press often overgeneralizes topics. But we are talking about many studies.

    As far as the quotes by the authors of the study, who are researchers, that doesn't mean the quotes aren't cherry picked and why, as I stated above, I would really like to see the full study.

    You make a good point and I'll try to find some other sources, if possible.

    Barb

    ETA Just saw your edit. Do you have a citation for the source? Thanks.

    I have bookmarked this article. It's a good summary of recent studies showing that some supplements may have negative heath effects and the history of deregulation of supplements in the US. Plus it's written by one of my favorite medical experts Paul Offit!:thumbsup:

    I also supplement with vitamin D as my D3 is very low.

    I'm also a "stoner". I started developing kidney stones about a year and a half ago.* High blood calcium is associated with kidney stones. So while I I can't supplement with calcium, I don't have to limit foods high in calcium. Getting calcium through foods reduces the incidence of kidney stones but calcium supplements increase your risk of getting kidney stones.

    The following is a study which shows this relationship with an explanation.

    http://www.medicinenet.com/script/main/art.asp?articlekey=1887&page=2

    Like you I try to get my vitamins through foods. It's not as hard as you would think to get the nutrients you need. But tbh, it's easier said than done when you're ill.

    *That's the short version.:D

    Chocolate bars with bacon? Never heard of that. Interesting combination.

    I'm not wild about bacon.

    Wait, are you saying chocolate bacon or chocolate and bacon separately?

    Either way you have a thoughtful hubby!

    The salty caramel chocolate is very good, too.

    This research also discusses health benefits of increased ROS formation, and therefore drawbacks because of to much antioxidants: http://www.sciencedirect.com/science/article/pii/S0891584911003121

    Antioxidants like ellagic acid, sulforaphane and luteolin have anti-cancer and anti-metastasis effects.

    You will find lots of stuff if you look on PubMed. Let me start you of with ellagic acid.

    I don't think it is the antioxidant property of ellagic acid, sulforaphane and luteolin that has the anti-cancer effect, though.
