The aim of the study was to evaluate the impact of statin use on the incidence of advanced age-related macular degeneration among patients with large drusen. The study included 744 patients, aged 50 years or more, who were followed for at least five years. Eligibility criteria for the clinical trial required that the participants have more than ten large drusen and visual acuity no better than 20/40 in each eye.

(Drusen are yellow deposits under the retina. While drusen likely do not cause age-related macular degeneration, their presence increases a person’s risk of developing age-related macular degeneration. In the expression, 20/40 vision, the 20 is the distance in feet between the subject and the chart. The 40 means that the subject can read the chart (from 20 feet away) as well as a normal person could read the same chart from 40 feet away).

The study found that patients taking statins had a 19% increased risk of developing advanced age-related macular degeneration compared to patients not taking statins.

This study, named the Cholesterol and Recurrent Events Trial (CARE) investigated the effects of statins in patients with coronary disease, who have average (below 240 mg/dL or 6.2 mmol/L) cholesterol levels. The study was a double-blind, placebo controlled trial lasting five years and included 4,159 patients who received either 40 mg of pravastatin per day or placebo.

The study found:
(a) Those taking statins had a 19% reduced risk of death from coronary heart disease compared to placebo.
(b) Those taking statins had a 45% increased risk of death due to cardiovascular but noncoronary causes compared to placebo.
(c) Those taking statins had a 100% increased risk of violent death compared to placebo.
(d) Those taking statins had a 9% increased risk of death from cancer compared to placebo.
(e) Those taking statins had a 7% increased risk of any cancer compared to placebo.
(f) Women taking statins had a 1100% increased risk of breast cancer compared to placebo.

Dr Uffe Ravnskov, an expert in cholesterol, statins and heart disease, commented in his book 'The Cholesterol Myths': "Considering the large number of participants, this result doesn't seem particularly impressive... In fact, the reduction in coronary heart disease deaths was offset by the fact that in the treatment (statin) group a few more had died from other causes".

Do Processed and Red Meat Cause Cancer?

Today, the World Health Organization's International Agency for Research on Cancer published a statement in The Lancet detailing its position on the carcinogenicity of processed and red meat (1).  The statement, resulting from a meeting of 22 scientists from 10 countries, concluded that processed meat is a group 1 carcinogen, meaning that it is "definitely carcinogenic to humans".  They also judged that red meat is a group 2A carcinogen, meaning that it probably causes cancer but the evidence isn't as strong.  They're mostly referring to the links between processed and red meat and digestive tract cancer, particularly cancers of the colon and rectum.

These statements were met with a media frenzy, and the expected furor from the meat industry.  The most surprising thing, for me, is that anyone would be surprised by the IARC's statement.

Why Do Girls and Boys Reach Puberty Younger Than They Used To?

Girls, and probably boys, are reaching puberty years younger than they did in our great-grandparents' generation.  Why?  There's no shortage of explanations, but the primary reason is probably quite simple.

The Hamilton Rating Scale for Depression is a multiple item questionnaire used to provide an indication of depression. A score of 0-7 is considered to be normal. Scores of 20 or higher indicate moderate, severe, or very severe depression.

This study investigated the association between cholesterol levels and depression. The research was carried out on a normal population in a primary care setting using the Hamilton Rating Scale for Depression.

The study found that those with low cholesterol scored significantly higher on the Hamilton Rating Scale for Depression, thereby low cholesterol was significantly associated with higher rates of depression.

Healthy life. Image: www.renovemedspa.org
Cancer is a deadly disease, but with a healthy lifestyle, you can prevent it. Get unique tips from the article below, so you can get enlightenment.

Cancer usually occurs from genetic, environmental, food, and lifestyle factors. The bodies of most people will fight off cancer cells before they have a chance to multiply and grow; however, sometimes the body is unable to eliminate toxic cells.

The best way to fight off cancer cells before they have a chance to attack the body is to make sure your immune system is healthy. Effective ways to prevent and fight off cancer cell are as follows:

Step 1
Avoid sugar and sugar substitutes to prevent cancer. Cancer feeds off sugar and the harmful chemicals in sugar substitutes.

Step 2
Substitute unsweetened soy milk for regular milk. Most milk has added hormones that are toxic to the body.


Step 3
Drink green tea to boost your immune system. Green tea contains anti-oxidants that help prevent cancer.


Step 4
Eat less meat and more fish. Most meat in the United States contain harmful hormones, antibiotics, and parasites, which are harmful to everyone, especially people who already have cancer.

Step 5
Eat more fresh vegetables, fruit, nuts, seeds, and whole grains to prevent cancer.

Step 6
immune system, prevent cancer, healthy tips, prevent cancer tips, healthy food, anti-oxidants, Take supplements that boost the immune system. Take anti-oxidants, vitamins, minerals, and amino acids to help your immune system. Vitamin E helps the body eliminate bad cells.

Step 7
Exercise every day. Even a daily twenty minute walk will help improve your immune system and prevent cancer.

Will You Fill Out This Paleo Diet Survey?

This week, I received an e-mail from a graduate student at Humboldt State University named May Patiño.  She asked me to share her online research survey targeted to Paleo dieters.  Here are the goals of her research, in her words:
The main objective of my study is exploring how the Paleo diet is being implemented in practice.  I would like to assess the health outcomes of these practices, as well evaluate how closely they conform to, or deviate from ways this diet is being described in theoretical literature, and implemented in controlled diet trials. I also want to be able to use the data collected to help explain what is driving the popularity of the ancestral health movement. Ultimately, I would like this information to be used to better inform protocols for controlled diet trails.
The survey took me about 40 minutes to complete.  You're welcome to participate whether or not you're on the Paleo diet.  Please consider taking the survey, for the love of science!

Low-density-lipoprotein cholesterol concentrations and risk of incident diabetes: epidemiological and genetic insights from the Framingham Heart Study.
Andersson C, Lyass A, Larson MG, Robins SJ, Vasan RS
Framingham Heart Study, 73 Mt Wayte Avenue, Suite 2, Framingham, MA, 01702-5827, USA. ca@heart.dk.

This study can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/26409460

One of the aims of this study was to assess the association of low density lipoprotein (LDL) cholesterol levels with diabetes risk. The study included 6,011 individuals, (average age 50 years), who were not treated with cholesterol lowering or antihypertensive medications and who were free from cardiovascular disease at the start of the study. Diabetes was assessed at the next examination (average 4.5 years later).

The study found that each standard deviation increase in LDL levels was associated with a 19% reduced risk of diabetes. 

Andersson concluded: "These observations may contribute to our understanding of why lipid-lowering treatment may cause diabetes in some individuals."
