Essential Sleep (Part 6). Cognitive decine and the brain

Essential Sleep (Part 6). Cognitive decine and the brain

Late night

Research on 59 participants, those who were confirmed night owls (preferring late to bed and late to rise) had lower integrity of the white matter in various areas of the brain (Rosenberg et al 2014). Lower integrity in these areas has been linked to depression and cognitive instability.

Health and productivity effects of poor sleep

Health and productivity effects of poor sleep

Obvious symptoms of sleep deprivation constant yawning and the tendency to doze off when not active for a while; for example, when watching television, Grogginess when waking in the morning Sleepy grogginess experienced all day long (sleep inertia) Poor concentration and mood changes (more irritable).


Some of the physical effects found from long term fatigue are heart disease, diabetes, high blood pressure, gastrointestinal disorders and depression (Workplace health and safety QLD, 2008).  A study conducted by Andersen involving rats also showed sleep deprivation affects the expression of genes related to metabolic processes, response to stimulus and signalling pathways (Andersen et al, 2009). 

Numerous studies have shown that even a little bit of sleep deprivation decreases efficiency and increases risk of disease, including cardiovascular disease, cancer and diabetes.  Sleep deprivation has been shown to negatively affect endocrine (hormones) and metabolic functioning as well as nervous system balance (Nilsson, et al., 2004).  Sleep deprivation is associated with an increased concentration of cortisol plus other indicators of increased stress such as elevations in pulse rate, body temperature and adrenaline secretion (Vgontzas, et al.,1999).  Sleep deprivation also appears to increase blood concentrations of certain chemicals called cytokines and C-reactive proteins (Irwine, 2001 and Vgontzas, et al., 1998), indicating an inflammatory reaction.  The effect of unremitting low-grade inflammation may be to damage the inner walls of the arteries, which sometimes leads to vessel narrowing, high blood pressure, stroke, and heart disease (Irwine, 2001).  During truncated sleep, your heart might have to work harder, constricting blood vessels and increasing blood pressure even more, which could conceivably result in a heart attack or stroke (Martins, 2003). 

Sleep is as important to the human body as food and water, but most of us don’t get enough sleep.  Insufficient sleep or disruptions to the sleep contribute to adverse health effects. Numerous studies have also shown that even a little bit of sleep deprivation decreases efficiency and increases risk of disease, including cardiovascular disease. 

Initial changes to cardiovascular system from insomnia include hypertension, which is a potent co‑morbidity for other cardiovascular diseases. Hypertension has been linked to reduced sleep duration, with the highest correlation shown under 6 hours sleep per night (Gottlieb et al. 2006). However, associations have also been made between sleep of over 9 hours per night and hypertension and obesity. Furthermore this has not been supported at all in some studies and PPI in one older North American population actually showed a reduced risk of hypertension (Phillips, BOková and Enrigh, 2009.).

A study of 71,617 female health professionals found that sleeping fewer than five hours per night was associated with a 39 percent increase in the risk of coronary heart disease; even six hours per night showed an increase of 18 percent compared to sleeping eight hours per night (Najib, et al., 2003).  In an analysis of data on more than one million people, the levels of nearly all forms of death were two-and-a-half times higher for people who slept four hours or less compared to those who slept between seven and eight hours on average

A study of 71,617 female health professionals found that sleeping fewer than five hours per night was associated with a 39 percent increase in the risk of coronary heart disease; even six hours per night showed an increase of 18 percent compared to sleeping eight hours per night.  In an analysis of data on more than one million people, the levels of nearly all forms of death were two-and-a-half times higher for people who slept four hours or less compared to those who slept between seven and eight hours on average

Experimentally, sleep deprivation has been shown to negatively affect glucose metabolism and to enhance factors associated with Type 2 diabetes (Nilsson, et al., 2004).  Research has also shown that people who experience sleep disorders were as much as three times as likely to develop Type 2 diabetes (Kawakami, 2004).  Subjects in one study demonstrated impaired glucose tolerance for ten days after four hours of sleep deprivation (Spiegel, et al.,1999).  It is also found that sleep deprivation can play a role in obesity.  Sleep deficits bring about physiologic changes in the hormonal signals that promote hunger and, perhaps thereby, obesity (Spiegel, et al., 2004).  One study found that after two days of sleep curtailment the subjects had reduced levels of the fat-derived hormone leptin and increased levels of the stomach-derived hormone ghrelin.  These hormones are responsible for regulating hunger and appetite (Spiegel, et al., 2004).  These hormonal differences are likely to increase appetite, which could help explain the relative high BMI in short sleepers.

Coffee consumption good for ageing

Coffee consumption good for ageing

Coffee, one of the world's most consumed beverages, has potential antiaging effects.

A recent study in mice confirms a lot of the human studies that aged mice that consumed either caffeine-containing regular or decaffeinated coffee had decreased plasma-free fatty acids (blood fat levels) and increased metabolism which is closely associated with aging, in the liver. In addition, consumption of regular coffee increased the food and water intake, locomotor activity, volume of oxygen consumption, and respiration exchange ratio of aged mice.

Moreover, coffee consumption by the aged population had a positive effect on behavioral energy and lipid metabolism.

Coffee includes a wide array of components that can have potential implication on health including caffeine, chlorogenic acids and diterpenes. The information gathered in recent years has generated a new concept of coffee, one which does not match the common belief that coffee is mostly harmful. While there are still some concerns about coffee consumption during pregnancy and the effects of caffeine on the young (kids), there is a significant positive impact of coffee on the cardiovascular system, and on the metabolism of carbohydrates and fats. It is also important to note that science is not black or white on most topics related to health as there are too many confounding factors to consider. That is why there will never be a definitive study to prove coffee is good or bad.

The good news for those coffee drinkers is that contrary to previous beliefs, the various forms of arterial cardiovascular disease, arrhythmia (irregular heart beat) or heart insufficiency seem unaffected by coffee intake. Coffee is associated with a reduction in the incidence of diabetes and liver disease. Protection seems to exist also for Parkinson's disease among the neurological disorders, while its potential as an osteoporosis risk factor is under debate. Its effect on cancer risk depends on the tissue concerned, although it appears to favour risk reduction and lowering the risk of cancer overall. Overall coffee consumption seems to reduce mortality and the biggest benefits appear to be as we age. Personally , while it might be beneficial s we age I love the smell but don’t like the taste so I will stick to my tea.

From a cardiovascular standpoint, coffee consumption reduces the risks of type 2 diabetes mellitus and hypertension, as well as other conditions associated with cardiovascular risk such as obesity and depression; but it may adversely affect lipid (fat) profiles depending on how the beverage is prepared, especially if prepared with lots of sugar. Moreover, large epidemiological studies suggest that regular coffee drinkers have reduced risks for mortality—both cardiovascular and all-cause mortality. The potential benefits also include protection against neurodegenerative diseases, improved asthma control, and lower risk of some gastrointestinal diseases. A daily intake of about 2 to 3 cups of coffee appears to be safe and is associated with beneficial effects for most of the studied health outcomes.

Vegetable oils and margarine are no better than saturated animal fats for the heart.

Vegetable oils and margarine are no better than saturated animal fats for the heart.

More evidence from the best controlled randomised controlled trials found that replacing saturated fats with mostly vegetable-seed oils (n-6 PUFA) does not reduce coronary heart disease mortality or total mortality.

So why does the heart foundation continue to sell margarine and vegetable oils to the public?

A cornerstone of outdated dietary advice is the recommendation to reduce the intake of saturated fatty acids (SFA) as a means of reducing the risk of coronary heart disease (CHD). There are a few variations of this recommendation, these include: 1) advice to reduce the intake of SFA; 2) advice to replace SFA with monounsaturated fatty acids (MUFA) and mostly n-6 polyunsaturated fatty acids (PUFA); and 3) advice to replace SFA with mostly n-6 PUFA. It also recommends margarine and vegetable oils instead of butter and animal fats. However, the evidence for this recommendation has been questioned by recent a number of meta-analyses of observational studies and clinical trials. These studies have consistently found that the intake of SFA is not independently associated with the incidence of CHD.

Unfortunately, mega 6 oils such as corn, safflower, cottonseed, sunflower, and soya are now in nearly all our foods. Apart from the obvious consumption of vegetable oils and margarine you buy in the supermarket—which I hope you are now not going to buy—Omega 6 oils are hidden in most foods. You will find vegetable oils in just about every processed and semi-processed food including bread, cakes, and breakfast cereals and in lots of the plant-based drinks like almond or soya milk the main ingredient is often vegetable oil. All the takeaway foods, frozen and packaged dinners have Omega 6 oils. Even the “new” Mediterranean diet is laden with Omega 6 oils. When you buy olives, pesto sauce, sundried tomatoes or anything soaking in oil it is now vegetable oil in which it is soaked, not olive oil because vegetable oil is cheaper, unless you go to Italy where most foods are still soaked in olive oil. It is almost impossible to get away from the excess of Omega 6 oils. Time to read the labels! Factory produced eggs have 20 times more Omega 6 than Omega 3 compared to free-range eggs, which have a ratio of 1:1. Similarly, grain-fed beef (which I do not recommend you eat) has around 20:1 Omega 6 to Omega 3 oils because the cows are fed grains rich in Omega 6 oils. Alpha linolenic acid is found in the grass and is converted into the important Omega 3 oils by the animals. It is found only in grass-fed animals. Grass-fed cows are also a lot less stressed and have as a result lower levels of inflammation.

Statin Statistics - Lies and Deception

Statin Statistics - Lies and Deception

Tens of millions of unsuspecting people are prescribed cholesterol-lowering drugs—statins like Pravachol®, Zocor® and Lipitor®—each year at a cost of more than billions of pounds with very little, if any, benefit. In the U.S., some 40 million people currently take statins at a cost of more than $3.00 per pill, more than $1,000 per year, totaling more than $40 billion a year.

While there are many exaggerated claims and a lot of hype about the benefits of statins, there are also many studies showing no benefits at all. The pro-statin hype is based on the misuse and abuse of statistics. Various independent studies in prestigious, peer-reviewed journals have shown that statin use in primary prevention—that is, to save lives—has minimal or no value in reducing mortality and certainly nothing that is considered anywhere near clinically significant to warrant their widespread use. It does not matter how one manipulates the statistics, the results just aren’t there. In data gathered in 2009 from six trials, a review of the efficacy in lowering the risk of death with statins found virtually no difference between the treatment group and the control group.[i] There are many more of these studies.

In an independent meta-analysis (when a number of studies are put together to achieve more statistical power) of randomized controlled trials in patients without CVD, statin therapy decreased the incidence of major coronary and cerebrovascular events and revascularizations but not coronary heart disease or overall mortality.[ii] Taking statins for a number of years will not reduce mortality: “Primary prevention with statins provides only small and clinically hardly relevant improvement of cardiovascular morbidity/mortality.”[iii] “Hardly relevant” means there is virtually no clinical benefit; as the authors of these particular studies are independent, they gain nothing by stating this. Another review found that “current clinical evidence does not demonstrate that titrating lipid therapy (trying to lower cholesterol with statins) to achieve proposed low LDL cholesterol levels is beneficial or safe.”[iv] In other words, lowering lipids has no real benefit and has the potential for adverse effects. Following up on this, in a major independent review of studies funded by the Ministry of Health of British Columbia (Canada) on statins and primary prevention, researchers reported that “statins have not been shown to provide an overall health benefit in primary prevention trials.”[v] This is a government report carried out by an independent university yet its findings are still ignored.

The problem really comes down to vested interests and the abuse of statistics. To overcome the limitations of small studies, vested parties combine many studies into a meta-analysis. The researchers themselves select the studies used in the meta-analysis. A fundamental problem is that researchers with direct links to drug companies have the authority to select the most positive studies and ignore the rest—including independent studies not funded by pharmaceutical companies. Despite this, they have still not been able to show any clinically significant findings.

With few new studies being conducted, the drug company researchers look at the data every year or so and conduct another meta-analysis to show virtually the same results as the earlier studies. This makes it appear that another big study has been conducted, but frequently the data is simply reused from older studies. There is very little clinical significance in these studies, yet the media outlets pick up the drug companies’ PR and repeat, word for word, the pharmaceutical industry’s party line. 

As readers of the scientific journals, we should not be confused between statistical significance and clinical significance. For an outcome to be “statistically significant” means that the outcome was likely result of the treatment—whether the result was 100% effective or less than 0.1% effective. That is, if you treat 1,000 people to save one life (0.1%) it may be statistically significant but it is not clinically significant. “Clinical significance” means 20% to 30% or more. The drug companies’ most positive studies on statins for prevention of CVD report statistical significance, mostly 1% or less, and none have found any clinical significance.

Busy medical professionals don’t have time to review the statistics; few of them may be aware of the different ways the statistics are manipulated. A study found that a high number of psychiatrists did not understand the difference between statistical and clinical significance.[vi] Consultants, that is the senior psychiatrists, did less well than senior trainees. So if the experienced professionals don’t understand the results of these studies, how do we expect the media or public to understand? The entire situation is also complicated by the comments in abstracts of the studies, in which researchers state the evidence is significant and don’t mention that it is only statistically significant but not clinically significant. The drug companies fund the researchers and authors of most of these studies.

More deception

The studies on statins also report “relative risk,” not “absolute risk” or “real risk.” The relative risk reduction is highly misleading[vii],[viii],[ix],[x].[xi]  if not deceptive. An example of relative risk is: if you have four people in a study who die in the placebo group (no drug) compared to three people who die in the drug treatment group—that is, four were expected to die but with the drug only three did—then there is a 25% relative risk reduction. However, to get this effect of saving one life you would have to treat 1,000 people and the real risk reduction is 0.1%. Relative risk is like adding 1+1 to get 11 or 2+5 to get 25 or more. How can the pharmaceutical companies and the researchers working for them get away with this? This is probably because (at least in my experience) most people are afraid of statistics.

In studies by the Medical Research Council dating back to the late 1980s, researchers found that of 1,000 men ranging in age from 35 to 64 who received treatment for mild hypertension over five years, there were six fewer strokes and two fewer cardiovascular events than would be expected.[xii],[xiii] The real risk reduction over five years was 0.9%. Ten years later, a study of Pravachol® was released in the media, with much fanfare, as having a 22% drop (relative risk, not real risk) in mortality. However, when one looks at the numbers and statistics behind the calculations, treating 1,000 middle-aged men who had hypercholesterolemia (high cholesterol) and no evidence of a previous heart attack with pravastatin for five years resulted in seven fewer deaths from cardiovascular causes, and two fewer deaths from other causes than would be expected in the absence of treatment.[xiv] The real risk reduction, however, was a mere 0.9%, less than 1% or nine lives out of 1,000 when treated for five years. The research was sponsored by Bristol-Myers Squibb Pharmaceutical (West of Scotland Coronary Prevention Study). Conservatively, put another way, researchers treated 1,000 people for five years at a total cost of over $5 million to save seven people from CVD. One might wish to compare this to the cost and efficacy of adopting healthy lifestyle choices.

In the Heart Protection Study in the United Kingdom, more than 20,000 participants aged 40 to 80 years with high risk of cardiovascular disease but average-to-low levels of total cholesterol and LDL cholesterol were treated with 40mg daily of simvastatin (marketed under several trade names including Zocor®). Of 20,500+ study participants, 577 on statins died from a heart attack, 701 not treated died from a heart attack. That is a 25% relative risk reduction over five years.[xv] Sounds good, doesn’t it? An interesting point is that using their statistical method, the researchers got their own claims wrong.[xvi] The real percentage improvement is actually 1.7%. Over the five-year study, they saved 25 people per year in a high-risk population with previous cerebrovascular disease, peripheral artery disease, renal impairment or diabetes. These are seriously ill people and the researchers still achieved a benefit of only 1.7%. Researchers neglected to mention that around 30,000 people were not allowed in or dropped from the study and not counted in the percentage of people with side effects. There were 10,269 people on statins and 10,267 people on a placebo.[xvii]

A study of 90,056 participants combining 14 randomised trials looked at the best outcome for people who had pre-existing conditions: 47% had pre-existing chronic heart disease, 21% had a history of diabetes and 55% a history of hypertension. The death rate was 8.5% among the statin group compared to 9.7% in the control group. This difference represents 1.2%. That is, if you treat 100 people who already have serious pre-existing diseases that predispose them to a heart attack or stroke, you are likely to save 1.2 people.[xviii] The study made no mention of side effects for all participants.

The well-known JUPITER study compared a placebo group to a statin-taking group. The study found that there were 68 heart attacks in the placebo group and 31 heart attacks in the drug treatment group—a 58% relative risk reduction. There were 64 strokes in the placebo group, compared to 33 strokes in the treatment group, a relative risk reduction of 48%.[xix] Sounds good, doesn’t it? However, the drug treatment group had 8,901 participants in it. In real terms, the heart attack risk went from a very low 0.76% to 0.35% and the risk of stroke went from 0.72% to 0.37%. Effectively, if you treat 300 people with expensive and dangerous drugs you might save one life. Under the best possible scenario, the real risk reduction was well under one half of one percent. The real risk reduction of consuming a handful of raw mixed nuts is much higher. It is interesting to note that one of the risk factors used to select the participants in the study was C- Reactive Protein (CRP), an indicator of inflammation and the real cause of the problem.

In an independent assessment of the same statistics in 2010 titled “Cholesterol Lowering, Cardiovascular Diseases, and the Rosuvastatin-JUPITER Controversy. A Critical Reappraisal “ by Michel de Lorgeril and her 8 colleagues found that “the JUPITER Study” was severely flawed.[xx] This recent analysis did a careful and independent review of both results and methods used in the Jupiter Study and reported that the “trial was flawed”. In an unprecedented attack on the study they (scientist other than myself usually don’t say boo even when it is serious) stated that “The possibility that bias entered the trial is particularly concerning because of the strong commercial interest in the study.”  In other words the big pharmaceutical money influenced the study. And concluded "The results of the trial do not support the use of statin treatment for primary prevention of cardiovascular diseases and raise troubling questions concerning the role of commercial sponsors.” This is a scathing attack in scientific terms of the earlier drug company sponsored study. Scientist do not go out of their way to create waves but these ones have not just found different results but also criticised the earlier studies link with pharmaceutical industry. It highlights not only that the studies don’t show any significant results but these studies and the education of our doctors is strongly influenced by the drug companies.[xxi]

More recently, a study reported in the BMJ was a meta-analysis of 10 randomized clinical trials of about 70,000 people followed for an average of four years.[xxii] In these trials, people with risk factors for cardiovascular disease but no history of existing disease were randomized to receive statins or no treatment. The relative risk reduction was 12% for total mortality, 30% for coronary event and 19% for a cerebrovascular event (stroke). However, the real risk reduction was 0.6%, 1.3% and 0.4% respectively. The actual number needed to treat to save one life was 167. Despite this outcome the authors of the study concluded, “In patients without established cardiovascular disease but with cardiovascular risk factors, statin use was associated with significantly (statistical not clinical) improved survival and large (statistical) reductions in the risk of major cardiovascular events.” (“emphasis added.”).  In fact, the authors had significant associations with the drug companies and failed to mention it was statistically significant but not clinically significant. Again, busy medical professionals tend to read only the abstracts; claims like this are pretty convincing, though very misleading.

More telling however, is the latest findings in June 2010 where two major independent studies, one the re analysis of the Jupiter Study reported above and the other “A Meta-analysis of 11 Randomized Controlled Trials Involving 65 229 Participants” (don’t worry about the title) by Ray Kausik and 6 other independent researchers. The study, wait for it, found the use of statins in high-risk individuals was not associated with a statistically significant reduction in mortality. That is, they don’t save lives. Their data combined from 11 studies with 65 229 participants followed for approximately 244 000 person-years, a very big study, reported that this “meta-analysis did not find evidence for the benefit of statin therapy on all-cause mortality in a high-risk primary prevention set-up.”  In other words they don’t save lives even in a high risk group. Even if you have all the elevated risk factors these drugs don’t work.

How many more studies to we need to do to show these drugs don’t work?

Even the economists agree with me

It is not only the scientists jumping up and down but also the economists are continually questioning the reason for so much statin treatment. In an economic review of statin use, authors reported that it is not cost-effective to treat low-risk people and also stated, “Economic analyses need to increase their transparency to reduce their vulnerability to bias and increase their reproducibility.”[xxiii] A recent study in the U.K. on reducing the cost of coronary heart disease mortality[xxiv] found statins in primary prevention cost £27 828 per life-years gained (LYG), reaching £69 373 per LYG in men aged 35 to 44. That is, to add one year to a person’s life requires spending £69 373 per year. The authors reported, “Amounts of NHS funding are being spent on relatively less cost-effective interventions, such as statins for primary prevention.”[xxv] There are now dozens of studies like this that pose the same question I am asking: Why are we using these drugs when they are not effective, but you can also add, especially when they have serous side effects?

The overwhelming outcome of all of these studies, no matter which combination used, even conducted with biases to give the best possible results, is that to possibly save a single life in a high-risk group one has to treat nearly 50 people in a low-risk group. In the population, between 100 and 1,000 people must be treated, with the possibility of dangerous side effects, to potentially save one life. Perhaps we might say that every life is worth that. Indeed, every life is valuable! A nutritional and lifestyle approach can save many lives. Unfortunately the use of statins comes with a high economic price, especially considering that nutrition and lifestyle changes can bring about much greater real benefits and even save money.
