"There's no way you can get all the nutrients you require from food (especially with the depleted soils in Western Australia). You must take supplements."
That might just possibly be true for organic vegans who grow their own food in unimproved soils, but Mr Treloar has obviously never managed an agricultural enterprise. He also seems to think that all the food in the shops comes solely from the surrounding local area. Of course, EoR suspects him of being a Big Altie shill, since he's constantly promoting his own products.
"Echinacea is the best herb to take over a long time as a preventative - but it must be a very good quality one."
More Big Altie propaganda. If you take any product over a period of weeks and months, of course your sniffles will resolve. If they don't, it's your fault for buying the cheap stuff from a supermarket, rather than your friendly local naturopath.
Asthma attacks are the result of the body trying to restore its pH balance. A "Russian breathing technique" (EoR presumes he means Buteyko, but there may well be other Russian breathing techniques he remains unaware of) has been very successful in addressing things like asthma and fatigue. Mr Treloar recommends nose breathing rather than mouth breathing to maintain a suitable pH balance and asthma free lifestyle. For the life of him, EoR can't see what the difference is what orifice air is taken in through once it reaches the trachea. How do the lungs go "Oh no, this air came in through the mouth. There goes the pH! And the neighbourhood!"?
"It has been proven that Vitamin C and Zinc reduces the length of a cold by 50%." Well, one rather poor study indicated zinc (not a combination of zinc and vitamin C) reduced the length of a cold by 42% (Mr Treloar is obviously rounding up his statistics). Others indicated no effect. The Straight Dope gives a brief overview, including the statement that
A similar situation arose 20 years ago, only the cold cure in question was vitamin C. That controversy ended indecisively, and today you don't hear much about vitamin C as a cold cure.
Unless you trust in Mr Treloar, of course.
Visit coldcure.com for Mr Eby's take on the subject. Zinc cures colds. And, according to the links on the front page also has an effect in (EoR freely admits he didn't even bother clicking on any of them, his brain was hurting so much) angina pectoris, leukemia, chronic sinusitis, "many modern illness" [sic], herpes simplex, menstrual cramping and bloating, mononucleosis, HIV and AIDS, depression, arthritis, navicular disease, and smallpox.
