Every time I go to the grocery store, I see shelves stuffed with alkaline water. I always shake my head, because I happen to know what the body does with any food or water that is alkaline or acidic. It buffers it to the normal pH of the body so that alkaline water doesn’t do anything. Well, it is expensive.
There are a lot of bogus reasons to drink alkaline water, but we’re going to focus on just one of the claims — it helps prevent cancer. I’ll make this simple, no it does not.
There are so many inaccurate, misleading, and harmful claims about cancer that I could spend years just debunking them. One of the most popular assertions is that acidic blood causes cancer — that is, if you lower the pH of the blood, it creates an environment to let cancer thrive.
Now, I have written this about a hundred times on this blog (I am not kidding) — there are only a handful of scientifically sound methods to potentially lower your risk of cancer. Quit smoking is near the top. Stay out of the sun. Maintain a healthy (that is, very low) weight. Don’t drink alcohol. Get exercise. And a handful more.
And even if you do all of them, you just reduce your absolute risk, not completely eliminate it. You could randomly get a set of mutations – there are several trillion cells in the body, and even if genetic copying in cell division or transcription were 99.999% perfect, it still leaves millions of chances of mutations – that lead to cancer.
And then there are at least 200-250 different cancers, all with different causes, pathophysiologies, prognoses, and treatments. In other words, even if you found some miracle way to prevent one cancer 100% of the time, it probably will not affect the other 200 or so cancers. We have tended to conflate cancer as one disease when it is a large set of diseases that have the same general physiology but aren’t truly related.
Cancer is scary because it is so random. In many cases, the treatment is so harsh. And people are so interested in anything that may prevent cancer. And if it’s simple like “eat superfoods like kale and blueberries,” or “reduce acid in your blood,” the instinct is to try it out.
But let’s examine how and if acidic blood causes cancer. Spoiler alert – it doesn’t. Continue reading “Alkaline water — don’t waste your money, it’s pure, unfettered woo”
