lets put this in perspective.

"A simple, inexpensive approach of drinking silicon-rich waters is now being promoted as a way of enhancing the elimination of aluminum from the body, along with the hopes of helping people prevent and treat AD. Researchers asked patients with Alzheimer's to drink a liter (about 34 ounces) of a silicon-rich mineral water each day for 12 weeks. This "special water" increased the removal of aluminum via the kidneys into the urine and clinical improvement was seen in 3 of the 15 patients with AD. These silicon-rich beverages are easily found in stores and via the Internet."My recommendation is to (1) throw out your aluminum pots and pans (use modern non-stick ceramic titanium-based cookware), (2) eat a starch-based diet prepared without aluminum additives, and (3) avoid aluminum-containing hygiene products. Adding silicon-rich drinking water appears to also be a safe and effective over-the-counter technique to remove aluminum that has already accumulated in your body.I see 3 recommendations. The mention of the silicon rich water differs from recommendation #3 and is not listed as recommendation #4 so I don't see it as a recommendation.
You have known Dr Mcdougall a very long time. When he is passionate about something, have you ever seen him use the word "appears?"
Not me.
So, the above doesn't seem like an recommendation, just a note of interest of something that may have some possible benefit.
There are only a few studies that directly looked at this. The water they used in the study quoted in the article above is not available in the USA. It had about 43 mg of silica per liter. In another study, the amount was about 10 mg per day and in another it was 55 mg/l.
There are two waters readily available in the USA that do have similar amounts listed on their label. There may be more, but I only know of two with the amount of silica actually listed on the label. These are Volvic water, which has about 32 mg/L and Fiji water, which has about 93 mg/L
I guess you can drink a bottle of either one of these a day and I don't see any harm in doing that but also not convinced of a benefit.
Fiji is about 1/2 the price and has twice as much so would be the better deal.
