Inflammation is an important risk factor in metabolic syndrome, diabetes and heart disease. This study tested the effects of low-fat and high-fat diets on markers of inflammation. This was a 12 week randomised, controlled, dietary intervention trial and included 40 overweight men and women, aged 18-55 years.

The subjects consumed diets of either:
(i) 12% carbohydrate, 59% fat, 28% protein. (High-fat diet).
(ii) 56% carbohydrate, 24% fat, 20% protein. (Low-fat diet).

The study found there was an overall greater anti-inflammatory effect associated with the high-fat diet, as evidenced by greater decreases in inflammatory markers such as: Tumor necrosis factor-alpha, interleukin 6, interleukin 8, monocyte chemotactic protein-1, E-selectin, intercellular adhesion molecules, and plasminogen activator inhibitor-1.

The results of the study reveal that a high-fat diet reduces inflammation compared to a low fat diet.

This paper is an analysis of 17 studies that investigated the connection between breastfeeding and the risk of been overweight in later life.

The study found:
(a) Compared to those who were exclusively formula-fed, those who were breastfed for 1-3 months had a 19% decreased risk of been overweight in later life.
(b) Compared to those who were exclusively formula-fed, those who were breastfed for 4-6 months had a 24% decreased risk of been overweight in later life.
(c) Compared to those who were exclusively formula-fed, those who were breastfed for 7-9 months had a 33% decreased risk of been overweight in later life.
(d) Compared to those who were exclusively formula-fed, those who were breastfed for more than 9 months had a 32% decreased risk of been overweight in later life.

The data from the study reveals that a longer duration of breast feeding (up to nine months) is associated with a decreased risk of been overweight in later life.

This study investigated the association between statins and bladder cancer. The study, which lasted for 46 months, analyzed the clinical outcomes of 84 patients who had received the bacille Calmette–Guérin vaccine for the treatment of non–muscle-invasive bladder cancer.

The study found:
(a) In 53% of the patients who took statins, the tumor became more aggressive, whereas this change occurred in only 18% of the patients who did not take statins.
(b) 42% of the patients in the statin group had to undergo radical cystectomy, (radical cystectomy is the removal of the entire bladder, nearby lymph nodes, part of the urethra, and nearby organs that may contain cancer cells), as compared with only 14% of the patients who did not take statins.

In patients undergoing treatment for bladder cancer, the use of statins was significantly associated with an increased risk of tumor progression and a subsequent need for radical cystectomy.

Phosphocreatine is a substance that is fundamental to the ability of the body to produce muscular energy.

Elevated blood levels of creatine kinase are indicative of muscle damage.

The study investigated the association of statin treatment on recovery from exercise. The study included ten patients, (who were subject to a four-week regimen of statin therapy), who had their phosphocreatine and creatine kinase levels measured pre- and post-statin therapy.

The study found:
(a) Phosphocreatine levels took 97% longer to recover from exercise after statin therapy.
(b) Creatine kinase levels rose by 17.7% after statin therapy.

The results of the study suggest that statin therapy may impair energy production and promote muscle damage.

Michalak J, Zhang XC, Jacobi F.

This study can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/22676203

The study investigated the association between meat eaters or vegetarians and mental disorders. The study included 4,181 participants, aged 18 to 65 years and examined the prevalence rates of mental disorders at one month, 12 months and lifetime.

(Prevalence rates is the proportion of people in a population who have a particular disease over a specified period of time).

The following mental disorders were investigated:
(i) Depressive disorders: Major depressive disorder, dysthymic disorder.
(ii) Anxiety disorders: Panic disorder (with or without agoraphobia), agoraphobia without a history of panic disorder; specific phobias, social phobia; obsessive-compulsive disorder, generalized anxiety disorder.
(iii) Somatoform disorders and syndromes: Somatization Disorder, “abridged somatization disorder” hypochondriasis and pain disorder.
(iv) Eating disorders: Anorexia nervosa, bulimia nervosa (including atypical anorexia nervosa and bulimia nervosa).

The study found:
(a) Regarding depressive disorders:
(a:i) Vegetarians had 44% higher one month prevalence risk of depressive disorders than meat eaters.
(a:ii) Vegetarians had 75% higher 12 month prevalence risk of depressive disorders than meat eaters.
(a:iii) Vegetarians had 48% higher lifetime prevalence risk of depressive disorders than meat eaters.
(b) Regarding anxiety disorders:
(b:i) Vegetarians had 76% higher one month prevalence risk of anxiety disorders than meat eaters.
(b:ii) Vegetarians had 87% higher 12 month prevalence risk of anxiety disorders than meat eaters.
(b:iii) Vegetarians had 77% higher lifetime prevalence risk of anxiety disorders than meat eaters.
(c) Regarding somatoform disorders:
(c:i) Vegetarians had 72% higher one month prevalence risk of somatoform disorders than meat eaters.
(c:ii) Vegetarians had 104% higher 12 month prevalence risk of somatoform disorders than meat eaters.
(c:iii) Vegetarians had 93% higher lifetime prevalence risk of somatoform disorders than meat eaters.
(d) Regarding eating disorders:
For eating disorders prevalence risk could not be calculated accurately. However, descriptively the study found elevated one month, 12 month and lifetime prevalence rates in the vegetarian group.
 
The study also compared the kinds of food eaten by the participants with and without mental disorders.
 
The study found for meat consumption:
(e) Regarding depressive disorders:
(e:i) Those with a one month prevalence of depressive disorders consumed 5.4% less meat than those without a one month prevalence of depressive disorders.
(e:ii) Those with a 12 month prevalence of depressive disorders consumed 6.2% less meat than those without a 12 month prevalence of depressive disorders.
(e:iii) Those with a lifetime prevalence of depressive disorders consumed 7.6% less meat than those without a one month prevalence of depressive disorders.
(f) Regarding anxiety disorders:
(f:i) Those with a one month prevalence of anxiety disorders consumed 4.8% less meat than those without a one month prevalence of anxiety disorders.
(f:ii) Those with a 12 month prevalence of anxiety disorders consumed 5.6% less meat than those without a 12 month prevalence of anxiety disorders.
(f:iii) Those with a lifetime prevalence of anxiety disorders consumed 5.1% less meat than those without a one month prevalence of anxiety disorders.
(g) Regarding somatoform disorders:
(g:i) Those with a one month prevalence of somatoform disorders consumed 7.4% less meat than those without a one month prevalence of somatoform disorders.
(g:ii) Those with a 12 month prevalence of somatoform disorders consumed 5.6% less meat than those without a 12 month prevalence of somatoform  disorders.
(g:iii) Those with a lifetime prevalence of somatoform disorders consumed 6.2% less meat than those without a one month prevalence of somatoform disorders.
(h) Regarding eating disorders:
(h:i) Those with a one month prevalence of eating disorders consumed 181.3% less meat than those without a one month prevalence of eating disorders.
(h:ii) Those with a 12 month prevalence of eating disorders consumed 70.7% less meat than those without a 12 month prevalence of eating disorders.
(h:iii) Those with a lifetime prevalence of eating disorders consumed 0.3% less meat than those without a one month prevalence of eating disorders.
 
The results of the study strongly demonstrate that diets containing meat are associated with better mental health.

Review of my book "Cholesterol and Saturated Fat Prevent Heart Disease" by Wendy Schwartz

0 comments
Here's a review of my book Cholesterol and Saturated Fat Prevent Heart Disease by Wendy Schwartz.
Wendy's article
3 Reasons Why Saturated Fats Are Not Bad and The Earth is Not Flat
If I tried to tell you today that the earth is flat you would laugh at me because you know that we have sent men into space and the earth’s shape has been photographed.  It is most definitely round - near as I can tell. Despite this, the theory/myth that the earth is flat was commonly held for centuries. It sure looks flat when you look out at the horizon.

So it is with fat. The notion that saturated fats and cholesterol are bad for you has pervaded modern thinking despite clear-cut information to the contrary. It seems logical that fat would clog arteries and make you fat, doesn't it? I can understand how this rumor got started, but what is the truth? 

In his well-researched book, Cholesterol and Saturated Fat Prevent Heart Disease, David Evans, a researcher who also blogs at Healthy Diets and Science provides evidence from 101 scientific papers representing a huge body of research indicating that in fact, far from causing heart disease in humans, eating a diet rich in saturated fats may actually prevent heart disease.  You heard me right. 
It turns out that there is a strong likelihood that animal fats may actually be good for you. Having spent the past month eating more animal fat than I have in my life, I would tend to agree, based on my health improvements. I just feel better.  My blood sugar is consistently within the normal range now and my weight is down by a few pounds.  In addition, my appetite is more well-controlled and I am sleeping better. 

While some studies cited in Evans’ book are epidemiological in nature, meaning that they look at trends across population groups rather than double-blind scientific experiments, there is plenty of data that points to a reduction in heart disease risk as intake of healthy animal fats goes up.

Here are just a few studies cited that stand out to me:

A 6-year study of nearly 22,000 men who were initially free of heart disease, but were smokers between the ages of 50-69, (a high risk group) was conducted by researchers in Finland. Those who consumed the highest level of saturated fats had a 27% decrease in coronary death and a 13% decrease in coronary events when compared with the group that ate the least amount of saturated fats and the highest amount of man-made polyunsaturates (margarines and oils).1 

A study of healthy young men (only 10 participants), but well-controlled, measured post-meal blood triglycerides as a risk factor.  The research showed that butter, which is higher in saturated fats, induced the lowest rise in post-meal triglycerides when compared with olive oil or sunflower oil.2A large epidemiological study of 1 million men in different parts of India revealed that those in regions where fat consumption (mainly animal fats) was 19 times higher, had a decreased incidence of heart disease - 7% less.3 

While dietary studies are notoriously challenging, there have been many studies linking increases in carbohydrate consumption and insulin levels to heart disease. Conversely, studies of those with high fat consumption have only yielded rises in HDL (the good cholesterol).  The bottom line is, there is no proof that saturated fats lead to heart disease and there is some evidence that the higher the diet is in fat, the more heart disease rates decline.

In David Evans’ book, he highlights the study that fostered the myth of the lipid hypothesis which was conducted by Ancel Keys (also known as the Seven Countries Study) and provides evidence that points out it could have just as easily proven that saturated fats provide protection against heart disease. 

The seven countries Keys based his research on were the ones that provided data that conveniently fit with his hypothesis.  Had Keys selected seven other countries out of the 20+ countries he initially surveyed, he could have drawn the complete opposite conclusion. Also, the seven countries study had very few scientific controls in place and the methodology for collecting information was not stringent enough to qualify for sound scientific research today.  (More to come about this topic in my new eBook,  Go Paleo! A Shopping Survival Guide.)

David Evans’ book is filled with additional tidbits of research that, when taken together, paint a clear picture that shows animal fats and other saturated fats are not the culprit in heart disease after all. He is not alone in this belief and it would be great if research could be done with Paleo / Primal eaters in the future. Saturated fats from grass fed and pasture raised animals have quite a different fatty acid profile.

This Japanes study investigated the association of cholesterol levels with the risk of stroke. The study included 1,814 adults, aged 40 to 69, who were followed for eight years.

The researchers found the following:
(a) Those with low cholesterol levels were more prone to cerebral hemorrhage.
(b) The results of the study correspond well with the observed fact that stroke incidence or death rate in Japan is higher in populations with low cholesterol levels, and also with the fact that death rate from hemorrhage declines with increasing cholesterol levels.

The study reveals that low cholesterol levels are associated with an increase in cerebral hemorrhage rates.

The study investigated the relationship between high-density lipoprotein (HDL) cholesterol levels and the risk of gastric cancer. The study included 184 patients who had undergone gastrectomy (gastrectomy is a partial or full surgical removal of the stomach).

The patients were divided into two groups:
(i) Normal levels of HDL cholesterol group.
(ii) Low levels of HDL cholesterol group.

The study found:
(a) In the low HDL cholesterol group the cancer had significantly increased in the lymphatic and vascular systems.
(b) The prognosis of the patients in the normal HDL cholesterol group was significantly better than those in the low HDL cholesterol group.

The results of the study show a correlation between low HDL cholesterol levels and an increased risk of gastric cancer.

A diet high in saturated fat raises HDL cholesterol levels. See here here and here.

The objective of the study was to determine the relationship of cholesterol levels with clinical outcomes in critically ill surgical patients. (Clinical outcomes included death, infection subsequent to intensive care unit admission, length of intensive care unit stay, and magnitude of organ dysfunction). The study included 111 patients with a variety of critical illnesses, for whom cholesterol levels were determined within 24 hours of admission to a surgical intensive care unit.
 
Average cholesterol levels of the patients were extremely low:
(i) Total cholesterol, 127 mg/dL (3.2 mmol/L)
(ii) Low-density lipoprotein (LDL) cholesterol, 75 mg/dL (1.9 mmol/L)
(iii) High-density lipoprotein (HDL) cholesterol, 29 mg/dL (.75 mmol/L)
 
Clinical outcomes were related to whether the admission cholesterol levels were above (56 patients) or below (55 patients) 120 mg/dL (3.1 mmol/L).
 
The study found:
(a) Each of the clinical outcomes occurred between 1.9- and 3.5-fold more frequently in the very low cholesterol (less than 120 mg/dL or 3.1 mmol/L) group.
(b) Nine patients died during the hospitalization. Seven of the nine patients who died were in the very low cholesterol (less than 120 mg/dL or 3.1 mmol/L) group.
 
The results of the study show that low cholesterol levels are associated with an inreased risk of death in critically ill surgical patients.

This study examined the relationship between artificially sweetened beverage consumption and long-term weight gain. The study included 3,682 adult participants whose Body Mass Index (BMI) was measured at the start of the study and after eight years.

The study found:
(a) Men who had artificially sweetened beverages had a 40% inrease in BMI compared to men who were nonusers.
(b) Women who had artificially sweetened beverages had a 51% inrease in BMI compared to women who were nonusers.
(c) Those who consumed diet soft drinks had a 42% increase in BMI compared to those who did not consume diet soft drinks.
(d) Those who consumed artificially sweetened tea had a 40% increase in BMI compared to those who did not consume artificially sweetened tea.
(e) Those who consumed artificially sweetened coffee had a 32% increase in BMI compared to those who did not consume artificially sweetened coffee.

The findings of the study raise the question whether artificially sweetener use might be fueling-rather than fighting-the escalating obesity epidemic.

The study compared levels of cholesterol and fats in cerebrospinal fluid (cerebrospinal fluid is found in the brain and spinal canal) in Alzheimers patients and subjects without Alzheimers. The study assessed the brain tissue at postmortem in 30 Alzheimers cases and 31 age-matched control patients.

The study found:
(a) Cholesterol levels in the cerebrospinal fluid of patients without alzheimer's was 55% higher than in patients with Alzheimer's.
(b) Fatty acid levels (fat molecules) in the cerebrospinal fluid of patients without alzheimer's was 522% higher than in patients with Alzheimer's.
(c) Phospholipid levels (phospholipids contain two molecules of fat and are a major component of cell membranes) in the cerebrospinal fluid of patients without alzheimer's was 1650% higher than in patients with Alzheimer's.

The results of the study show that Alzheimer’s patients have significantly reduced levels of cholesterol and fats in the cerebrospinal fluid.

Amazon Review of my book "Cholesterol and Saturated Fat Prevent Heart Disease - Evidence from 101 Scientific Papers"

5.0 out of 5 stars Easy to understand, packed full of amazing information!, November 3, 2012

When I first saw this book I assumed I would not be able to understand "scientific papers" as I have no scientific knowledge (aside from gr. 12 biology, 25 yrs ago), but the studies were explained so well and strung together so well, they were easy and enjoyable to read.

I was blown away by the evidence contrary to the typical eat-low-fat-for-your-heart medical advice, I especially enjoyed Chapter 5, "Comments by Eminent Professors and Doctors" (leading experts on the subject of cardiovascular disease), the glossary, and Appendix 3 which provided quick summaries of one or two lines of each of the studies.

After my father who was slender and had low cholesterol, died of a heart attack, my vegetarian/whole foods mom got a brain aneurysm and my young, fit husband developed a heart condition, I began a research quest and started to question all I knew for certain about diet and health. This led to my adoption of a low carbohydrate, real food lifestyle which has greatly improved my health. Reading this book provided me with the evidence behind my intuitive and physical experience of ridding myself of the fear of eating natural fat. I will be passing it out to each of my friends who asks me why I am not afraid of clogging my arteries. It was reassuring and it is a great accessible resource. (I will be buying a few more copies to give to my doctors as well).

When blood sugar levels remain high for several hours, dehydration and more serious complications can develop. Even slightly raised blood sugar levels (a fasting blood sugar over 109 mg/dL or 6.05 mmol/L) when unrecognized - can damage multiple tissues in the brain, kidneys, and arteries.

This study investigated the effects of statins on fasting blood sugar levels. The study included diabetics and non-diabetics, statin users and non-users, and analysed the change in fasting blood sugar levels in 345,417 patients, average age 61, over a two year period.

The study found:
(a) Fasting blood sugar levels increased by an extra 29% in non-diabetic statin users compared to non-diabetic non-users.
(b) Fasting blood sugar levels increased by an extra 18% in diabetic statin users compared to diabetic non-users.

The study reveals that statin use is associated with a rise of fasting blood glucose levels in patients with and without diabetes.
