How Flaky Can Detox Ideas Get

Flaky detox ideas: what the alternative quacks forget is the existence of the lymphatic system. This is what cleans body, removes shed cells, unwelcome biological molecules, own white blood cells that ate viruses and bacteria, blood glucose bound old hemoglobin and other materials. All of that flows to the spleen, the true detox center. Any other detox approach is lethal. Body pH is precise. Anything changing it will cause serious malfunction. Liver has no refuse storage department, it is like a molecular assembly site. Unnecessary water soluble materials and light waste get filtered out by the kidneys. Some out from the skin.
If liver is presented with any new molecule - always getting to the liver through the portal vein - it starts taking it apart into known biological materials, like acetyl COA, fatty acids, glycerides, vitamin building blocks, and makes new molecules, and sends whatever necessary into blood stream for the muscles.

Reading up on the quack detox ideas sound like they have done nothing, not centuries of white coat research.
They did quick rationalizing or back pedaling when it comes to the lymphatic system, and there is a separate field of quacky recommendation. In the spirit of the well known century long blood letting, the quacks make claim that the botanicals, also peddled to the unsuspecting people as liver detox, exist also as lymph drainers. Of course, they do not elaborate on where the drainage occurs, and since when they have had the time to do research on this, and on how many impressively many people. This is disgusting. When you hear science reduced to the word "drainer," maybe it's money down the drain.

Question: Acidic drink interacting with the plastic bottle.

Would you expect any chemical interaction, BTW, when apple-cider vinegar sits inside the plastic bottle they sell it in (versus glass) -- could acid leach anything from the plastic bottle?

If it is ldpe, or hdpe, then the worst case scenario would be ethylene, which either would evaporate, as it does from apples, or oxidize into ethanol. Which would be quickly worked into to the AcetylCoA, one of the main sprockets of the Krebs cycle. But the polymer is very durable, and it takes sunlight UV and high heat to break it.
if polypropylene, then it would be a propylene, eventually evaporating, or becoming isopropyl alcohol (rubbing alcohol), or acetone, which would evaporate, or remain within the body's native acetone content.
the cola bottle material, PETE, is very durable, and is highly resistant to chemicals, especially weak food acids. Acetic acid in vinegar is nothing compared to concentrated main acids.
To summarize, whatever monomer leaching into food would be somewhat below the biologically relevant concentration.

Breaking Bad Chemistry

So sad that the imagination of visual arts trivializes the evil and mixes it with science.
Stumbled on a two clips from the Breaking Bad series, capturing my memories of work in chem labs, human resources and the importance of coffee therefor:
