Arsenic is a “carcinogenic heavy steel,” and “[t]he main mechanism of [arsenic]-related harm [appears to be] oxidative stress.” It’s the arsenic-induced “[a]ccumulation of free radicals” that may kill off cells, and harm our DNA. After which, the double whammy is that it might disrupt our physique’s skill to restore our DNA as soon as it’s broken. Effectively, if the harm is oxidation, what about consuming antioxidant-rich meals, such because the spice turmeric, which incorporates an antioxidant pigment often known as curcumin? As anybody acquainted with my movies can attest, “quite a few medical [trials] have prompt…therapeutic efficacy in opposition to [a variety of] human illnesses, together with most cancers…, diabetes…, Alzheimer’s…,…and inflammatory bowel…,” joint, lung, pores and skin, and eye illnesses.

When it comes to safety in opposition to heavy metals, they counsel turmeric might each assist scavenge free radicals in addition to chelate, or bind up, heavy metals—full with a elaborate colourful diagram. However, it’s all simply concept, till you set it to the check. Sadly, till not too long ago, the assessments have been like this, the place you’ll be able to see if curcumin can shield in opposition to heavy metal-induced oxidation in puréed rat brains. Why can’t you simply give some turmeric to folks? It’s not like there aren’t tens of millions of individuals on the market who’ve been uncovered to arsenic, and will use some assist.

In what grew to become the best chemical catastrophe in human historical past, so-called “tube-wells” have been put in in Bangladesh to offer clear water. UNICEF meant effectively; too dangerous they didn’t check the water for arsenic. Individuals began exhibiting up with ft that seemed like this, and as many as one in ten in some components of the nation will now go on to die from cancers brought on by the arsenic publicity. This allowed the medical group to doc all types of fascinating cancers. However why not give them one thing which will assist—like turmeric curcumin?

“After figuring out the [extent of] DNA harm, 50% of…volunteers have been randomly chosen and prescribed curcumin capsules blended with [a little black pepper compound],” and the opposite half “have been…given a placebo.” Right here’s the quantity of DNA harm that was discovered within the curcumin and placebo teams of arsenic-exposed people earlier than the research began, in comparison with the DNA harm present in a management group of people not uncovered to arsenic, which remained the identical all through the research.

Now, they needed to determine a baseline within the arsenic-exposed teams. So, they waited for 3 months to start out the research. And, certainly, the DNA harm remained steady. Then, for 3 months, they proceeded to offer them the curcumin or the placebo. The placebo didn’t do a lot, however inside the first month, you possibly can see the curcumin working. And, by the third month, the DNA harm within the curcumin-treated arsenic group was no worse than in those that hadn’t been uncovered to arsenic in any respect.

And that’s wonderful. The “curcumin had an efficient function in [the] regression of DNA harm.” Sure, it’s “a wonderful antioxidant agent,” however what they discovered subsequently is that the curcumin undid the arsenic crippling of our DNA restore enzymes. So, it each helped stop the harm and facilitate restore. “Thus, curcumin…could also be a helpful modality for the prevention of arsenic-induced [cancer development].”

After all, you need to ensure that the turmeric itself isn’t contaminated with heavy metals. Oh, these poor children in Bangladesh. If it’s not one factor, it’s  one other. And, it’s not simply children in Bangladesh. Practically 1 / 4 of spices bought in Boston had lead in them. And, it’s not only a matter of shopping for U.S. versus international manufacturers, because the lead ranges have been not discovered to be statistically vital. How about simply consuming antioxidant-rich vegetables and fruit?

The explanation we care about DNA harm is that we care about most cancers. What for those who measured the beta-carotene ranges in folks uncovered to arsenic who went on to develop most cancers, in comparison with those that received uncovered to the identical quantity of arsenic, however didn’t get most cancers? Beta carotene is sort of a proxy for wholesome fruit and vegetable consumption. The best way you get excessive ranges in your blood is you eat a number of wholesome meals—like greens and candy potatoes. In comparison with these with low ranges, these with excessive ranges of beta carotene of their blood had 99% decrease odds of getting arsenic-induced most cancers—100 occasions decrease odds. So, for those who’re going to eat rice, why not some rice with some candy potatoes on prime?
