Gissi-HF Investigators, Tavazzi L, Maggioni AP, Marchioli R, Barlera S, Franzosi MG, Latini R, Lucci D, Nicolosi GL, Porcu M, Tognoni G.


The study investigated the effects of the statin rosuvastatin in patients with heart failure.

4,574  patients aged 18 years or older with chronic heart failure were assigned to either rosuvastatin 10 mg daily (2,285) or placebo (2,289) and followed up for 3.9 years. Death rates and admission to hospital for cardiovascular reasons were measured.

The study found:
  • 657 (29%) patients died from any cause in the rosuvastatin group and 644 (28%) in the placebo group.
  • 1305 (57%) patients in the rosuvastatin group and 1283 (56%) in the placebo group died or were admitted to hospital for cardiovascular reasons.

This trial shows that people with heart failure will live slightly longer and have less cardiovascular disease if they avoid statin treatment.

Reducing carbohydrate consumption may help to prevent cancer

Study title and authors:
Is there a role for carbohydrate restriction in the treatment and prevention of cancer?
Klement RJ, Kammerer U.

This paper can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/22029671

Dr. Rainer J Klement from the University Hospital of Wurzburg reviewed the evidence of 162 scientific papers regarding the subject of carbohydrate restriction and cancer.

Dr. Klement found:
  • Cancer, which might be considered a disease of civilization, was very rare among uncivilized hunter-gatherer societies. Their diet was mainly meat and fat, whereas modern diets have quickly changed to easily digestible carbohydrates derived mainly from grains. Our genes have not had time to adapt to the new carbohydrate foods, and diseases of civilization have ensued.
  • Reducing the amount of dietary carbohydrates could stop, or at least delay, the emergence of cancer, and that growth of already existing cancer could be slowed down.
  • Most carbohydrates are converted into glucose by the body. Most cancer cells depend on glucose for growth as their ability to use fats or ketone bodies has been impaired.
  • High carbohydrate diets cause a rise in insulin and insulin like growth factor levels which promote cancer growth.
  • Ketone bodies that are elevated when insulin and blood glucose levels are low, have been found to stop cancer cells growing.

Dr. Klement concludes that the evidence presented in the review shows that reduction of the high carbohydrate intake in modern diets may play an important role in cancer prevention.

The aim of the study was to evaluate the effects of a low-fat eating pattern on risk of colorectal cancer in postmenopausal women. In this 8 year trial 48,835 postmenopausal women aged 50 to 79 were recruited from 40 clinical centers throughout the United States and divided into 2 groups:
(i) Women in group (i) had an intensive behavioral modification program aimed to motivate and support reductions in dietary fat, to increase consumption of vegetables and fruits, and to increase grain servings by using group sessions, self-monitoring techniques, and other tailored and targeted strategies. (Low fat group)
(ii) Women in group (ii) continued eating as normal. (Higher fat group)

The study found:
(a) The women in the low fat group ate around 10% less fat compared to the women in the higher fat group.
(b) The women in the low fat group ate significantly more vegetable, fruit, and grain servings compared to the women in the higher fat group.
(c) The women in the low fat group had an 8% increase in colon cancer compared to the women in the higher fat group.

This 8 year study revealed that a higher fat diet reduces colon cancer by 8% compared to a low fat diet.

Research by a Nobel prize winner shows that high carbohydrate diets cause cancer

On the origin of cancer cells
Warburg O

This paper can be accessed at: http://www.sciencemag.org/content/123/3191/309.extract

Otto Warburg won the Nobel prize for medicine in 1931 for discovering that cancer cells are fundamentally different compared to healthy cells.

He found that energy and growth in cancer cells is mainly generated by the fermentation of glucose, unlike normal cells which contain tiny organelles inside them called mitochondria which work away producing enegy to keep the cells healthy. The mitochohdrial activity in cancer cells is impaired and cancer cells can use glucose by up to 200 fold the rate of healthy cells.

How does this relate to cancer and diet?

To produce energy humans mainly use either:
(i) Fat and ketone bodies.
(ii) Glucose.

Fat may be provided by dietary fat, and ketone bodies are compounds that are produced when fats are broken down for energy by the liver and kidneys. Almost all carbohydrates are broken down by the body into glucose.

Fat and ketone bodies need mitochondria to provide energy, whilst glucose also has the ability to provide energy by fermentation. This means that fat, ketone bodies and glucose can be used for energy by healthy cells, but only glucose can be used by cancer cells.

The implication of this is if you follow a very low carbohydrate diet it is very difficult for cancerous cells to survive because they will have little or no energy to feed on.

Warburgs research shows that a high carbohydrate diet will encourage cancer growth, whereas a diet low in carbohydrate and high in fat discourages the growth of cancer.

The association between high density lipoprotein (HDL) cholesterol, triglyceride levels and breast cancer risk was investigated in  5,207 Danish women, aged 30 - 80 over a 26 year period.

The study found:
(a) Higher triglyceride levels were associated with higher breast cancer incidence.
(b) Women who had the highest HDL cholesterol had a 70% reduction in breast cancer risk.

High Triglyceride levels are caused by low fat, high carbohydrate diets. See here.

The best way to increase your HDL cholesterol levels is to consume a diet rich in saturated fat. See here, here , herehere, and here.

The object of this study was to investigate the association between exposure to drugs such as statins and the occurrence of erectile dysfunction. Over a 20 year period the researchers extracted data about 110,685 men aged 13 - 80 years old who had reported an incidence of erectile dysfunction to see if they had being taking statins, fibrates or other drugs.

The study found:
(a) Statins users had a 275% increase in erectile dysfunction.
(b) Erectile dysfunction usually started to occur within 1 month.
(c) Just over half of these men recovered if they stopped taking the statins.
(d) Erectile dysfunction happened no matter what the dose or duration of the statin therapy.
(e) Fibrate users had a 260% increase in erectile dysfunction.
(f) Men on beta-adrenergic receptor antagonists (beta blockers) had 50% increased rates of erectile dysfunction.
(g) Those taking tricyclic antidepressants had double the risk of erectile dysfunction.
(h) Men having finasteride (used for male pattern baldness) were over 14 times more likely to suffer from erectile dysfunction.

This study reveals that statins and other drugs are a major risk factor in erectile dysfunction.

The aim of this analysis of 13 studies (which included 19,707 women) was to determine if cholesterol lowering drugs such as statins have any effect on heart disease rates and death rates in women. The study investigated results for both women with cardiovascular disease and without cardiovascular disease.

The study found:
(a) For women with heart disease statins marginally lower heart disease rates, however death rates from all causes remained the same.
(b) For women without heart disease statins marginally raise heart disease death rates, however death rates from all cause again remained the same.

This analysis of 13 studies found that statins offer no health benefits for women.

Dr. de Lorgeril notes that the results of cholesterol-lowering drug trials show no evidence that statin drugs lower the disease rates or death rates of people with or without coronary heart disease with one exception, and that is the JUPITER (Justification for the Use of Statins in Primary Prevention) trial. JUPITER reports a substantial decrease in the risk of cardiovascular diseases among patients without coronary heart disease and with normal or low cholesterol levels. 


The results of the JUPITER study were met with a massive media fanfare proclaiming the benefits of statin drugs. This enthusiastic recommendation has no doubt persuaded many people with normal cholesterol levels to start long term statin treatment.


The JUPITER trial tested the effects of rosuvastatin in patients without heart disease and with normal or low cholesterol levels but relatively high levels of C-reactive protein, a marker of inflammation. The study spanned 1,315 sites in 26 countries and included 17,802 people who were assigned either 20 mg/d of rosuvastatin or placebo.


3 recent trials with rosuvastatin (with the acronyms CORONA, GISSI-HF and AURORA) had been conducted, and all had failed to provide evidence that rosuvastatin therapy reduces heart disease complications.


The JUPITER trial was prematurely terminated on the grounds that it had generated evidence that the statin treatment had definitely reduced heart disease rates.


However the evidence shows otherwise:
(a) If you include people who had fatal and nonfatal heart attack and stroke - the trial was stopped after only 240 incidents. 
(b) There was no difference in the incidence of serious adverse events (total hospitalizations, prolongations of hospitalizations, cancer, and permanent disability) between the 2 groups.
(c) There was hardly any difference in death rates when the trial was ended, and the trend was showing that the statin groups death rate was increasing compared to the placebo group.


An "unequivocal reduction in cardiovascular mortality" was announced in March 2008 as the main justification for the premature trial termination.


However the actual facts again beg to differ:
(d) Fatal heart attacks were 9 in the statin group and 6 in the placebo group.
(e) Stroke death was 3 in the statin group compared to 6 taking the placebo.
So there was 12 cardiovascular deaths in each group. Hardly an "unequivocal reduction in cardiovascular mortality" as the JUPITER study authors concluded.


So why was the trial stopped early?


As stated earlier JUPITER was hailed in the media as a ringing endorsement for us all to start statin therapy. This was achieved by the authors of the study only highlighting some results of the trial and completely ignoring other, less favourable data. It also raises the suspicion that if the trial had continued then the results would have shown statins in an even more unfavourable light.


Rosuvastatin (sold under the brand name Crestor) is marketed and distributed by AstraZeneca Pharmaceuticals.


The JUPITER trial involved multiple conflicts of interest: 
(f) It was conducted by Astra Zeneca  with their obvious commercial interests. 
(g) Nine of 14 authors of the JUPITER article have financial ties to the Astra Zeneca. 
(h) The principal investigator has a personal conflict of interest as a co-holder of the patent for the C-reactive protein test.
(i) Astra Zenecas own investigators controlled and managed the raw data which increases the chance of bias appearing in the data.


Dr. de Lorgeril concludes:
(i) The results of the JUPITER trial are clinically inconsistent and therefore should not influence medical practice or clinical guidelines. 
(ii) The results of the JUPITER trial show that commercially sponsored clinical trials are at risk of poor quality and bias. 
(iii) The failure of the JUPITER trial to demonstrate a protective effect of rosuvastatin confirms the results of  more than 12 other cholesterol-lowering trials published in recent years, which all provided no evidence of protection against heart disease by cholesterol lowering. 
(iv) These failed trials strongly suggest that the presumed preventive effects of cholesterol-lowering drugs have been considerably exaggerated.


Dr.de Lorgeril ends by saying that the time has come for a critical reappraisal of cholesterol-lowering and statin treatments for the prevention of heart disease, and the emphasis on pharmaceuticals for the prevention of heart disease has diverted individual and public health attention away from other proven methods of prevention such as a healthy lifestyle, exercise and diet.

The aim of the trial was to ascertain the effects of pravastatin treatment in elderly men and women aged 70-82. The study involved 2,804 men and 3,000 women (total 5804) with a history of, or risk factors for, vascular disease. They were assigned into groups of either a statin (pravastatin) or placebo and the study lasted for just over 3 years. Total deaths and adverse events of heart attack, stroke, cancer etc were measured.

The results of the study revealed:
(a) Total serious adverse events were the same in both groups.
(b) Heart disease was 19% higher in the placebo group.
(c) Stroke risk was 3% higher in the pravastatin group.
(c) Cancer risk was 25% higher in the pravastatin group.
(d) Total death rates were 6% higher in the pravastatin group.

The results show that 3 years of statin treatment did not add one day to the life of the participants of the trial.

High levels of C-reactive protein and triglycerides are associated with an increased risk of heart disease. See here and here.

This study investigated the effects of 3 diets on diabetes and heart disease risk factors, such as weight, triglyceride levels and C-reactive protein levels in 96 overweight insulin-resistant women.

The diets were either:
(i) High-carbohydrate, high-fibre diet
(ii) High-protein diet
(iii) High-fat diet

The study found:
(a) When compared with the high carbohydrate diet, the high fat and high protein diets were shown to produce significantly greater reductions in weight loss.
(b) When compared with the high carbohydrate diet, the high fat and high protein diets were shown to produce significantly greater reductions in triglyceride levels.
(c) All diets reduced C-reactive protein levels. The high carbohydrate diet reduced them by 14.8% and the high protein diet by 17.3%. However by far the largest decrease in the dangerous C-reactive protein levels was on the high fat diet, with a 52.6% reduction.

This study reveals how a high fat diet is effective in reducing the risk of heart disease, with weight loss and the reduction of heart disease risk factors such as triglyceride and C-reactive protein levels.

Study title and author:
The cholesterol hypothesis: time for the obituary?
Scherstén T, Rosch PJ, Arfors KE, Sundberg R.
This paper can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/22070401

Dr. Schersten is a professor of Vascular Surgery, University of Göteborg and was previously Principal Secretary of the Swedish Medical Research Council.

Professor Schersten finds that the cholesterol hypothesis that links cholesterol intake and blood cholesterol levels to cardiovascular disease has little or no scientific backing that is relevant for the human species.

He concludes that the hypothesis is false and should be buried.
