1. Investigations and clinical research are normally carried out in developed, rich countries like America and Europe... but only on things that are within their culture and their lifestyle. No one carries out research on diets or practices or lifestyles that are present in Asia, middle east or other places. These are usually disregarded...unless they start impacting western lifestyles significantly (like Yoga).
Right - I fail to see how that justifies your suggestion that we haven't given the obviously fraudulent nonsense being pandered in the original argument a fair go. Yes, there is a strong streak of western mono-culturalism in western culture - that doesn't mean that bicarbonate of soda suddenly cures cancer in other places, or that oriental blood cells turn in to germs.
2. In countries like India there is very little interest and scarce resources to carry out such formal research on all the hundreds of traditional diets, customs and medical practices. Where are the sponsors, professionals and other resources? Many day to day practices, diets, food items are continued to be used on the basis of either traditional authority or anecdotal evidence and no one looks around for formal clinical research reports.
And... Firstly, we weren't looking at someone operating in India, but rather the US, where there is an agency that is supposed to enforce such things. Secondly, the lack of rigorous standards and enforcement in a developing nation doesn't mean that obviously fraudulent practices should get a free ride, even there.
3. In all countries, even in the UK I am sure, many traditional practices, customs and methods are still prevalent among the people, though no formal research has been conducted on these or their efficacy established beyond doubt. It is impossible to establish such matters beyond doubt in all cases. Who will sponsor the research?
On the contrary, any number of studies are conducted to see what the veracity of various 'old wives tales' and remedies might be. None of which, by the way, has the slightest impact on this baseless stupidity about 'alkalinity' in the human body.
4. Even in areas where formal research has been conducted and results published, one cannot be too sure of the correctness of the results. We have seen how oils and fats were rejected by doctors for decades (much against common wisdom) but are suddenly today being touted as healthy. Even the much talked about good cholesterol vs bad cholesterol issue, which formed the basis of most medical diagnosis....is now under review with many experts saying that cholesterol is not responsible for heart problems.
Yep. Science has been done badly, on occasion. At least it's been done, at least there was some sort of justification for the decisions, though.
So...what really is all this research worth?!
I'd say that the eradication of a number of previously common diseases, a massive increase in life-expectancy around the world (including the developing nations) and pharmaceutical and surgical techniques to mitigate or eradicate conditions that previously would have resulted in a torturous, hard, nasty, short life speak for themselves. If you're discarding the results of science and medicine out of hand, who's guilty of cultural imperialism now?
