Re: David Brownstein, MD, Caution with kelp

I hit "the alert good message" before you did, nyaah, nyaaah, n-n nyaah, nyaaah :::huge silly grin:::

GMTA, eh?

Regarding the arsenic in kelp - 'tis my thinking that we have no idea how much poison one would be getting, and in what form. While a healthy body in a strong state of health (cleansed/flushed and eating well) might be able to benefit from the kelp AND deal with the arsenic, I'd think it's a heckuva different 'outlook' for those that are weak or dealing with various problems already.

Proceed with knowledge & caution with the kelp folks...we're talking ARSENIC!

Toxicity of Arsenic

Arsenic and many of its compounds are especially potent poisons. Arsenic disrupts ATP production through several mechanisms including allosteric inhibition of the metabolic enzyme lipothiamide pyrophosphatase during glycolysis.[citation needed] At the level of the citric acid cycle, arsenic inhibits succinate dehydrogenase and by competing with phosphate it uncouples oxidative phosphorylation, thus inhibiting energy-linked reduction of NAD+, mitochondrial respiration, and ATP synthesis. Hydrogen peroxide production is also increased, which might form reactive oxygen species and oxidative stress. These metabolic interferences lead to death from multi-system organ failure (see arsenic poisoning) probably from necrotic cell death, not apoptosis. A post mortem reveals brick red colored mucosa, due to severe hemorrhage. Although arsenic causes toxicity, it can also play a protective role.[5].

Elemental arsenic and arsenic compounds are classified as "toxic" and "dangerous for the environment" in the European Union under directive 67/548/EEC.

The IARC recognizes arsenic and arsenic compounds as group 1 carcinogens, and the EU lists arsenic trioxide, arsenic pentoxide and arsenate salts as category 1 carcinogens.

Arsenic is known to cause arsenicosis due to its manifestation in drinking water, “the most common species being arsenate [HAsO42- ; As(V)] and arsenite [H3AsO3 ; As(III)]”. The ability of arsenic to undergo redox conversion between As(III) and As(V) makes its availability in the environment possible. According to Croal, Gralnick, Malasarn, and Newman, “[the] understanding [of] what stimulates As(III) oxidation and/or limits As(V) reduction is relevant for bioremediation of contaminated sites (Croal). The study of chemolithoautotrophic As(III) oxidizers and the heterotrophic As(V) reducers can help the understanding of the oxidation and/or reduction of arsenic.[6] Tweet
