I use the definition in my sig - evidence is anything that tends to make a proposition more or less true. Since customer satisfaction can as easily be present when there is no effect as when there is, its presence does not serve to make the proposition any more or less true.
Tough standard. It excludes virtually everything - even quality clinical studies have a margin of error meaning an effect may appear present when there is no effect.
Except that the research indicates that while you feel that all these wonderful things happen to you as a result of taking these supplements, the same things would happen to you if you weren't taking supplements.
Hang on, I thought we'd established the studies haven't been done, yet now you're claiming they
have been done? Care to share them? Remember, we're talking about the type of supplements I use, based on high nutrient plant concentrates.
Also, it requires a trivial interpretation of health such that death, disability, disease and discomfort have a minimal role in our state of health.
Ummm ... no. At no stage did I suggest they were not also components. Indeed, discomfort would quite clearly fall under the subjective areas I did mention.
It seems crazy to me as well. Yet research shows that when faced with the failure of their beliefs, the greater the sacrifice made for that belief, the stronger that belief becomes after failure.
Even if true in this case, it still doesn't follow that they'd be satisfied with the products efficacy.
You need to get out more.
There is an example
here.
Nowhere does he even imply he's taking supplements as a full replacement for a healthy diet. He seems to be using them as ... a
supplement.
This is almost (I don't actually know of any examples to the contrary) ubiquitous among supplement providers.
Here is the website of the world's largest nutritional supplement company -
www.nutrilite.com
Please provide me with a single example of that company exhibiting "distrust of the medical profession".
I'm simply looking at whether or not something is more likely to be true than not. The sorts of information that you refer to doesn't get you there. Not even for homocysteine, which at least has a few links established.
I know you're going to want supporting research, and I have it for each point, but I apologise in advance I don't have the time to dig them all out, here is the way I look at it.
1. The majority of people do not eat a recommended healthy diet
2. In many cases even the recommended healthy diet may provide nutrition for the avoidance of deficiency in most people, but not the negative effects of nutrient depletion.
3. A significant amount of research indicates larges numbers of people are deficient in one or more nutrients
4. Evolutionary processes combined with modern farming practices would predict that for some nutrients (particularly vitamins), the nutritional content of food would decrease over time
5. Other modern farming practices would predict that for some nutrients (particularly some minerals), the nutritional content of food would decrease over time.
6. Knowledge of human purchasing behaviour would further support 4 and 5 occurring.
7. An increasingly large body of material indicates that the overall nutritional content of food is indeed decreasing due to modern farming practices.
So ... I'm fairly convinced that the majority of people do not eat properly, and even if they did, for any given caloric intake it's harder today to get full nutritional needs than it was in the past.
(note: that's not to idolise the past, there were other issues then, including potential lack of variety)
8. A significant body of research nevertheless indicates that a diet high in fruit and vegetables leads to positive health outcomes.
9. Some research indicates that caloric needs are lower today than in the past due to lower activity levels (though an interesting recent study disputes this), meaning that, particularly combined with the above, people may need to consume excessive calories in order to receive sufficient micronutrients.
Ideal solution - grow food in such a way as to maximise nutrient content, eat healthy, and be active.
Reality - this doesn't happen and is difficult to achieve.
So you have perfectly logical, sensible reasons to believe that people may be suffering from the effects of inadequate nutrition, and you have plenty of research to indicate this is in fact the case.
One potential solution - nutrient supplementation,
something even the AMA started suggesting back in 2002
All of this makes perfect logical sense and is backed up by significant amounts of research in each area.
So then the question arises as to whether supplementation can help improve suboptimal nutrient status or not, and there's plenty of evidence it can.
Once your past that leap it's a matter of considering what form of supplementation would be most effective. Research indicates that in many cases plant-based nutrients are most effective. Furthermore, obtaining nutrients from existing food sources may mitigate against missing out on as yet unidentified phytonutrients. Indeed, research on some of Nutrilite's early plant concentrates show they contained significant levels of Vitamin E before it's importance had even been established or the current synthetic forms developed.
It seems to make perfect sense to me that high nutritional status plants converted into tablet form (with monitoring along the way) are a possible effective root to improving micronutrient status, and research shows it does indeed do this.
What's more, taken altogether you would
predict that the health outcomes would be exactly what I experienced - fewer incidences of ill health and an increased sense of well-being.
Why you have such a problem with this I frankly don't really understand.
Yes, there is more to health to that. However, "health" and "health outcomes" is my main area of research, and I can assure you that "I feel like I am better without actually being better in any way" does not form the bulk of what anyone means when talking about health.
By contrast, I spent a decade in public health research and people's perceived health outcomes was most certainly an aspect of our research. To say that whether people
feel healthy or not is irrelevant is to my mind incredibly , well, arrogant.
I am not persuaded that the results will be useful.
Right. Many people have suboptimal nutrient status. Suboptimal nutrient status has been shown to lead to poor health outcomes. Studies show nutrient status can be improved through supplementation.
But you don't think it's even think it's worth looking at whether supplementation can lead to improved health outcomes?
Oh dear.
