Diets Through History: The Good, Bad, and Scary
Much like high-fructose corn syrup, it's highly processed before you can add it to your tea, top your pancakes with it, or get it in an energy drink, bar, or other product. Languages Français Edit links. This is a pattern of evidence that is consistent with the null hypothesis, that NCGS does not exist — results are all over the place, with better-controlled studies tending not to show an effect, and on average there is only a tiny signal that does not reach statistical significance. What's really sad to me is that it isn't just society that blames dieters when they gain weight. The Fallibility of Human Reason in Everyday Life " Thomas Gilovich 37 Although this sounds good, it must be remembered that it is not the treatment itself that works. If no author information is provided, the source is cited instead.

Why diets don’t actually work, according to a researcher who has studied them for decades

Theoretically, when shrinking your waistline, there should be a reduction in the occurrence of carious lesions. Fermentable carbohydrates, especially sucrose, are absorbed by biofilm. This process causes bacterial plaque to produce acids. Frequent exposure of a susceptible tooth surface to the acid causes demineralization, the initiation of the caries process. Where caries come from The etiology of dental caries is multifactorial.

The chart to the left offers a visual guide. Streptococcus mutans and lactobacilli are bacteria found in biofilm that are highly cariogenic. Their cariogenic action has four aspects considered as separate effects: Metabolic activity of established bacteria under the influence of food residues and oral environment.

Advise your patients that these recommendations may help mask bad breath, but will only have a temporary effect on malodor until the source is remedied. When I was studying to receive my Doctorate of Naturopathic Medicine at the University of Bridgeport, diet and nutrition were a large part of our curriculum. We studied the biochemistry of many different foods and diets, and looked at their efficacy for optimal health, prevention of disease and weight loss.

The Blood Type Diet. I remember the first time I read about it: A diet based on the type of blood flowing through my veins? What could that have to do with anything? Well, in actuality the type of blood your heart has been pumping all your life could dictate which foods will decrease your risk for heart disease.

While some criticize the blood type diet, calling it a 'fad diet' with little foundation in nutritional history, researchers have actually revealed impressive scientific evidence to support Dr. Let's start with the basics behind the ABO blood grouping system. This system separates blood into four different categories based on specific chemical structures on the surface of each our red blood cells.

These structures are called antigens, markers found on the cells of the body that play a large role in the functionality of the immune system. This is because they know that when they test alternative medicines, they find that the do not work other than by psychological trickery.

In Steve Jobs had surgery to have a cancerous tumour from his pancreas removed, followed by a liver transplant in to help slow the deadly tumour. Unfortunately Steve Jobs was misled by various forms of alternative therapies. He tried acupuncture, dietary changes, various herbal remedies and "a few other treatments he found in the Internet or by consulting people [ Specially catered chemotherapy immediately worked well but the time that Jobs wasted on alternative therapies 'may have ultimately proven far more costly'.

The moral of this story is that even intelligent people can be misled by the claims of alternative medicine, to the cost of their own lives. Everyone who diagnoses or aids people with illness should be qualified in human biology and medicine. This is because the Human body is massively complicated, where symptoms are often not straight forward.

There are no simple, general rules guiding us as to what the true causes of bodily malaise are. But the popularity of alternative therapies has meant that this largely unregulated industry employs a great many inexperienced, under-qualified and wrongly qualified practitioners 8. One scientist, working for a skin care center, warns us that They have little or no experience with working on 'real' clients and their knowledge of anatomy and physiology is seriously lacking and in some cases, non existent!

In my opinion therapists who become self employed immediately after a short course can be a danger to clients. Because they have no experience. Some alternative qualifications are gained after a rapid 3-day course, which is clearly inadequate but still grants the student a good-looking certificate to hang confidently on their wall to impress patients with. Due to demand, some of these courses are only 1 day long. Put it another day: If you went to your doctor with a complaint and he revealed that he had had only one day's formal study, would you trust him?

Given the sketchy evidence for complementary medicine in general, you should be doubly distrustful of non-mainstream medical practices, even those who claim to be respectable. In addition, Susie Bell points out, many beauty therapists are self-employed so have no backing nor methods for checking up on the products and methods they use. Given the quantity of well-funded pseudo-science present in the cosmetics industry, inexperience and naivety well tend to bolster confusion about what works and what is worthwhile.

This subtle psychological effect occurs whether or not the underlying treatment actually works and it is strong enough to continually distort medical studies into the effectiveness of health products and can make products seems effective when they are not - it can even do the same for surgical practices. Such unexpected effects have been studied in greater and greater detail by medical researchers, and it has emerged that placebo effects come in various forms The placebo effect is particularly significant in areas such as pain relief and stress, and is therefore best at overcoming aches and pains, headaches, stress-related conditions including recovery from stomach ulcers 10 and skin rashes.

The placebo effect is the reason why these remedies appear to work for so many people, when in reality they don't have any medical effect 12 , 15 , 16 , 17 , 18 , 19 , 20 and its effects can often support erroneous ideas as to how disease works, and how healing works. How does it work? Many experiments have confirmed the ability of people to mentally control pain.

Finally, 6 It works best when delivered by a confident doctor who also believes the placebo will work The above paragraphs are the summary to my page on the placebo effect. For the full page, which has a section on how the placebo effect accidentally supports sham procedures and fake medicine, click here: The regression fallacy occurs when people extract too much meaning from chance events under specific circumstances.

Disease and fortune come and go: But when things are bad, some will "try" all manner of superstitious, meaningless and misguided practices - including all kinds of alternative therapies. Social psychologist David Myers agrees: Because we rarely employ controls and statistical analysis in our personal lives, it seems that any attempted solution, from the zany to the insane, has actually worked.

This is the cause of untold numbers of superstitions, magical practices, religious beliefs and pseudoscience, and can sometimes lead large numbers of people astray, especially when stories and anecdotes are published by the press. This is why many cults, religions and pseudo-therapeutic fads prey on the weak, depressed, down-and-outs and those who have recently experienced catastrophe. Such people are more likely to try new religions The solution is to be more cognizant of Human thinking errors.

Cause and effect must be analyzed statistically, carefully, and by social scientists who know how to discount confounding factors. Homeopathic practitioners spend a lot of time with patients, talking, which in itself can have positive effects, especially on illnesses that are influenced by psychological factors. They may emphasise nutrition and exercise. Many such treatments, especially the hands-on ones, are soothing. It is unsurprising if patients feel better. As homeopath Anthony Campbell puts it: A homeopathic consultation affords the patient an opportunity to talk at length about her or his problems to an attentive and sympathetic listener in a structured environment, and this in itself is therapeutic.

In other words, homeopathy is a form of psychotherapy. Critical Thinking, Skepticism, and Science Exposed! Several studies have confirmed that a pessimistic style of explaining bad events saying, "It's my responsibility, it's going to last, and it's going to undermine everything" makes illness more likely. We see in the above examples that stress is the emotional factor relevant in most of psychoimmunology. It has already been found that those with bad stress responses are more likely over the long term to suffer from ill health.

Those subjects who showed emotional stability and controlled responses to stress as adolescents had far better health at age 50 than did those subjects who had poor stress reactions when young. Even if such practices did nothing at all about the underlying organic causes of illness, they nevertheless help people to manage their symptoms, and they give people a sense of control over their illness - a sense of control that might be tremendously beneficial even if it turns out to be illusory.

Although this sounds good, it must be remembered that it is not the treatment itself that works. People are really being helped by psychotherapy - the time spent in personal reflection in an understanding environment, with nice and attentive practitioners.

In , Bertram Forer conducted a personality test, and then gave all of his students exactly the same personality profile, which he constructed from random horoscopes. This was occasionally previously known as the Barnum effect after a popularist entertainer. Extensive studies have found that this effect applies well to horoscopes, other astrological readings , messages given from the dead by spiritualists, various cold reading tricks and other profiling endeavours It is often mistaken for being a product of magical or supernatural means.

Lack of sociological sense and knowledge of cognitive errors and skeptical thinking methods leads some people to accept wild theories, based on misunderstandings of common experience. Freethought is healthy and appealing, but lack skeptical thinking also leads people into delusions and fantasies, and opens the doors for deception and consciously fraudulent practices, but most of all, for self-delusion.

Their downfalls are often occasioned only slowly, as the evidence and careful checking , plus, having time to think, slowly results in a culture-wide change of opinion. The most common thing that perpetuates these errors is believing in them based on personal testimonies. For example, many people argue that particular religions must be true because of how many other people believe in them 42 , Linked to this is many who chose to believe something because of the age of the belief Furthering such poor logic is a lack of understanding of statistical likelihood, and ignorance of thinking errors such as selection bias where we notice confirming evidence but ignore disconfirming evidence.

Because we instinctively value the popularity of a belief, our minds play a further trick on us: The basis of belief should be in the weight of evidence and not in a popularity contest. Practitioners themselves often exhibit the same credulity, allowing personal enthusiasm, pride and ego to completely obscure the need for scientific evidence.

He has been faced with sustained criticism from the scientific community for his claims about his sham products, but, rather than accept the evidence or fund proper trials of his stuff, he simply argues that "evidence-based medicine, at its worst, is exactly analogous to religious fundamentalism " 1.

Whilst it is true that fundamentalists are stubborn as can be, it also happens to be true that so is evidence. Amateur thinking, poor argumentation and misleading justifications for pseudo-scientific methods afflict both practitioners and patients. It is an example of "pseudo-science", where scientific terms are used without genuine understanding of their meaning, but in a way that makes out-there theories look reasonable at first glance.

Quantum Physics terminology and paraphernalia is often used as a basis for postulating how there might be 'souls' The eminent physicist Victor Stenger now deceased was a vocal critic of the abuse of quantum physics done by spiritualists of various kinds: Not surprisingly, this idea can be found in New Age periodicals and in many books on the metaphysical shelves of book stores" Aside from the "observer effect".

The Observe Effect and Quantum Entanglement are two the prime areas where non-scientific minds can often allow their imaginations to distort the science. However strange it may be, quantum physics is not a doorway to magic, even if peddlers of pseudoscience litter their works with scientific-sounding terminology. St John's Wort has generally been found to be mildly effective as an antidepressant 1 , and, this chemical alone has been responsible for many of the positive findings of research into alternative medicines.

It is not known as of how it works, although, it is only effective for everyday depression and not the severe and long-term forms of depression, for which proper medical assistance is required. A statistical analysis of a few thousand Chinese studies saw it most frequently used to treat ischaemic heart disease, stroke, chronic viral hepatitis, peptic ulcers, childhood diarrhoea, hyperlipidaemia, primary hypertension, upper digestive tract bleeding, diabetes mellitus, and pneumonia At least 26 comprehensive scientific studies of acupuncture have shown that it has no significant effect.

But three large studies have found that acupuncture does reduce the incidence of headaches and migraines - although two of those have shown that sticking pins in randomly is as effective as using traditional Chinese methods. Scientists understand how the neural and hormonal stimulation of needles work in a biochemical way to sometimes produce the results of acupuncture. What is known now is what has been suspected by practitioners for a long time: Instances of punctured lungs, increased pain, internal bleeding and other side-effects occur in up to 1 in 5 cases especially if a practitioner is not a medically trained doctor.

It works for pain relief for medically known reasons and also due to the placebo effect 49 , but the traditional mumbo-jumbo associated with traditional acupuncture is best ignored. How Does it Work? Of particular importance for a person's whole life is their month of birth. Practices based on astrology include the production of horoscopes, prediction of imminent or medium-term events in people's lives. Belief in astrology has been in long-term decline in the developed world and it is opposed by most established organized religions 52 , but it is still a popular feature of many new religious movements 53 , 54 and astrological charts can still be found in almost every daily newspaper in the form of horoscopes One academic writes that " there can be few Western Europeans who do not know their zodiac sign " It is part of the underlying theory of the New Age 56 , 57 , and is very popular in India in particular, where it is institutionalized.

Astrological predictions have been tested scientifically and have been comprehensively found to be mistaken in both theoretical underpinning and practical application 58 , 59 , For example, David Voas looked at over ten million married couples and found absolutely no statistical effects relating to marriages between people of particular zodiac signs And Chinese astrology has a long history, but, they group the stars into completely different constellations and give prominence to the lunar mansions "a sign lunar zodiac" So it is clear that astrology isn't based on any particular sound theory.

Over the last years, the precession of the equinoxes has meant that each equinox and solstice point has moved around 30 degrees; an Aquarius today genuinely isn't the same sign as an Aquarius from history.

Also, the dots that make up constellations are mostly stars, but many points are extremely distant galaxies, and the entire ensemble slowly moves and shifts over time, making most traditional methods of astrology useless Lack of knowledge of basic astronomy has made a mockery of astrology. Also poor is their biology: Especially if you don't ask subjects how long they were in the womb for.

The Forer Effect explains why most people readily accept that astrological descriptions are accurate - randomly assigned profiles are rated just as highly 63 , 64 , Astrological predictions of statistical likelihood of car crashes, divorces, etc, based on the month of birth nearly all fall foul of a simple statistical glitch - the Age Incidence Error
