The study showed no benefit for older adults (greater than 65) and that reported benefits are greatly reduced in some seasons (what season is that? flu season?). They did show the greatest benefit in young children. This can be due to many factors. One being reduced innate immunity due to a diet low in cholesterol, healthy fats, and sunlight exposure in addition to regularly consuming highly processed foods such as dairy, cereals, and grains. Cholesterol is a known factor the body uses to fight bacteria and viruses (in addition to other pathogens and toxins).
The risk associated with vaccines in any age group was not addressed. This includes immediate reactions and long-term harm associated with mercury accumulation.
The CDC states about vaccines,
There are a number of factors that can make getting a good vaccine virus strain for vaccine production challenging, including both scientific issues and issues of timing. Currently, only viruses grown in eggs can be used as vaccine virus strains. If specimens have been grown in other cell lines, they cannot be used for vaccine strains. However, more and more laboratories do not use eggs to grow influenza viruses, making it difficult to obtain potential vaccine strains. In addition, some influenza viruses, like H3N2 viruses, grow poorly in eggs, making it even more difficult to obtain possible vaccine strains. In terms of timing, in some years certain influenza viruses may not circulate until later in the influenza season, or a virus can change late in the season or from one season to the next. This can make it difficult to forecast which viruses will predominate the following season, but it can also make it difficult to identify a vaccine virus strain in time for the production process to begin."
This combined with the fact that the overwhelming majority of reported "flu" episodes are not actually influenza A or B. CDC data indicates around 20% incidence rate. This greatly reduces the reported benefit of vaccinations.
I fail to see real benefit of the flu vaccination when there is so much we can do to improve our immunity and health through diet and lifestyle. I propose there is a much wiser and smarter alternative. This includes changes in diet, sunlight exposure, sleep patterns, exercise, and stress reduction. Prevention through lifestyle change can also have a widespread impact on our health in other areas (such as cancer, heart disease, and obesity) and may even prevent the flu in the first place. This may even help eliminate toxins accumulated over time (including mercury from previous vaccinations) improving longevity and quality of life issues.
Here is a summary of the findings from a study in the Journal of Virology. Healthy children that received preventive treatment in the form of regular flu vaccinations were shown to have less antibodies across a wider variety of flu strains than non-vaccinated children. This is classic and shows how short-sighted and poorly designed preventive treatment can present long-term risks on our ability fight disease and reduce stressors to our health. Keep in mind stress (inflammation) is good short-term to fight acute alterations in our homeostasis but inflammation associated with chronic stressors can have detrimental impact across many systems in our body.
Artificially acquired immunity (flu vaccinations) cannot and should not replace naturally acquired humoral immunity in diseases that pose little risk in healthy children. Children subject to regular flu vaccines are at higher risk for future viral infections than children who do not receive routine influenza vaccinations. There are much better ways to upregulate innate and adaptive immunity. This should be the focus of carefully designed preventive treatment.
There is no magic pill (or shot) to cure or prevent our ails. Do you really want an injection filled toxins that slowly reduces your immune response year after year? The choice is yours.

Cardiac troponin I (CTI), a cardiac enzyme, is a reliable biomarker for heart damage. It is a protein that regulates the contractility of the heart and moderates calcium interaction with myocin and actin in the heart muscle. Actin and myocin work together in the production and utilization of energy in the heart muscles. When these fibers (actin) and protein (myocin which is used in cellular energy production) get damaged CTI increases. CTI is used to determine how much damage is occurring in the heart or how much the heart is being deprived of oxygen. Here is a great article that provides a nice benefit/risk analysis.
Yes, endurance exercise such as running, cycling, rowing, hiking, or any strenuous activity lasting mroe than 3 hours deprives the heart of oxygen, damages the heart muscles, and places an individual at higher risk for a heart attack during and for a period of time after strenuous activity.
Anytime your CTI is elevated, this places you at risk for cardiovascular attack. One study showed an increase of 34 % CTI in marathon runners.
Try HIIT instead. It stimulates latent human growth hormone while increasing cardiac reserve, lung capacity and lowering your risk for your cardiovascular disease without the associated risks of chronic aerobic activity.

There is debate in the scientific community whether or not cytokines are hormones. This may be due in part to their anatomy, origin, and level of concentration in the body. Cytokines can be concentrated 1,000s times greater during trauma or infection. Hormones are generally secreted by localized organs/glands such as the pancreas while cytokines can be generated from nearly every nucleated cell in our body including macrophages (WBCs), endothelial cells (interior of our body) like those that line our blood vessels, and epithelial cells (surface of our body) like our skin.
Here is a video representation courtesy of nucleusinc.org:
Just thinking about the structure of cytokines brings to light the fact that they are all highly dependent upon adequate levels of cholesterol since cell membrane structural integrity and intracellular communication are all reliant on cholesterol. In addition, WBCs act immunoprotectively with cholesterol in the blood to bind to and inactivate toxins such as bacteria, viruses, fungi, and free radicals. Here is a good site with practical application tips to reduce inflammation while enhancing the body's immunoprotective abilities naturally without dependence drugs which are partly responsible for iatrogenic disease and death. This also highlights one way cholesterol plays a role in immunity and how it may relate to other diseases such as cancer (McCully, Ravnskov & Rosch, 2011).
The greatest benefit of acute inflammation occurs when we have an infection. Inflammation stimulates cholesterol production. The bad news is that as chronic inflammation continues it inhibits nitric oxide (NO), a potent vasodilator, increases blood pressure and places the lining of our blood vessels at increased risk through atherosclerosis. The mechanisms responsible for atherosclerosis are very complex and the presence of cholesterol does not necessarily indicate cause. One of statins' benefits comes from inflammation reduction. According to Chris Masterjohn, (he describes the process in great detail here), statins can provide a co-occurring negative impact by reducing Coenzyme Q10 production which works in conjunction to NO to improve cardiovascular function and negate the effects of atherosclerosis. Statins are also known to cause muscle degeneration. Think about your heart. It is a muscle.
We need cytokines to keep us healthy when we get sick. We also need to understand how chronic inflammation occurs and to moderate the its effects by our lifestyle choices. When trying to mitigate these risks, understanding what causes inflammation and how to prevent it can reduce the risk of health problems down the road. We should approach it though our diet and lifestyle not a drug . . . unless you want to take that risk.

The healthiest sodium intake was between 4 to 6 grams. Those who consumed lower or much higher amounts had higher incidence of death from heart attacks and strokes. I have not seen any randomized studies providing definitive proof that a low sodium diet reduces heart attack and stroke rates. The current science seems to indicate a moderate intake of sodium for improved cardiovascular health is best.
This is in stark contrast with current government recommendations which are as follows:
- AI (adequate intake) is 1.5 grams
- Maximum intake is 2.3 grams
Both of these government recommended daily allowance references place the public at increased risk for heart attack and stroke. No wonder cardiovascular disease is the per-eminent killer in America just behind iatrogenic causes. Reducing sodium too much is dangerous and ineffective for controlling blood pressure as demonstrated by this metaanalysis due to increased renin secretion (raising blood pressure) and sodium depletion (which causes a sympathetic response). The study also showed that moderate sodium intake of 4.6 grams (within a healthy range) did have a positive impact on blood pressure.
This, in addition to other factors may be why sodium intake higher than government guidelines is good for you. Sodium has many roles in our body. Perhaps the most well known is the sodium potassium pump (SPP). This is what helps maintain our blood pressure and contractility. Every muscle is dependent upon proper function of the SPP in order to work effectively, especially your heart.
We shouldn't be afraid of sodium. We should be afraid of the processed foods that abuse sodium placing us at risk. Eating a healthy diet composes of whole, unprocessed foods and flavoring to taste with healthier versions of salt (like Himalayan or sea salt) and other healthy spices like cumin, cayenne, curry, and cinnamon are much wiser choices.

It also showed that people admitted to hospitals due to an infectious disease also had low cholesterol. Some common diseases noted were genitourinary infections, skin, and subcutaneous (just below the skin) infections. HIV and death from AIDS were also associated with lower cholesterol levels.
Patients with low TC suffering from chronic heart failure had a poorer prognosis after surgery and lower long-term survival rates. This also included patients recovering from abdominal surgeries. Another interesting note was that people suffering from hepatitis B including asymptomatic carriers also have lower TC levels.
Although the evidence shows that young and middle-aged men are at risk for heart disease with high cholesterol (this can be controlled through diet) their risk becomes negated when they get close to 50. As one gets older, higher cholesterol is associated with longevity 1, 2 in both men and women. This may be due to not only the cardioprotective effects of higher cholesterol but also to innate immunoprotective mechanisms associated higher TC.
Interestingly, eating a diet lower in fiber increases serum cholesterol due to the gut's increased ability to reabsorb cholesterol in the absence of fiber. In addition to this, diets higher in linoleic and linolenic acids (essential fatty acids) may help prevent or reverse atherosclerosis (yes, atherosclerosis can be reversed).
Another article showed that one cause of cardiovascular disease may result from bacterial communities reinfecting arterial walls. Suppressed immune response related to low cholesterol may be a contributing factor.
If you want to reduce your risk of infection and improve immunity response mechanisms, one thing to consider is maintaining healthy cholesterol levels. Cholesterol may also play a role in a number of autoimmune disorders.

Apparently, men are more susceptible to this correlation than women. They examined 19 cohort studies from the U.S., Europe, Israel, and Japan. TC is a calculation of cholesterol measurements of LDL, HDL, and triglycerides. The review noted high rates of cerebral hemorrhage with lower average TC. The rate of cerebral hemorrhage decreased as average TC went up in prospective populations. This was true in the Multiple Risk Factor Intervention Trial (MRFIT) in addition to increased incidence of colon cancer with lower TC. This may be related to what I wrote in an earlier post.
For women, 6 of the 11 studies showed no variation in cancer death rates across all spectrum of TC levels. There was an increased cancer risk in men when their TC levels fell below 180 mg/dL. In non-cancer and non-cardiovascular death rates, both men and women had similar risk findings. When TC was below 160 mg/dL there was a 40% increase of mortality compared to 160-199 mg/dL levels. Risk was also reduced by 10% when TC levels were between 200-240 mg/dL compared to the reference class (TC between 160-199 mg/dL levels).
This increase in non-cardiovascular deaths raises the issue of the dangers associated with taking cholesterol lowering drugs. These dangers are real and should not be taken likely (as mentioned in the study). Once again, when the data was pooled together, TC below 160 mg/dL was associated with highest risk of mortality.
Unfortunately, some of the data did not differentiate between age or sex but we can assume that having TC this low for anyone is quite risky. The review did take into account people with diabetes, smokers, CVD, alcohol intake, and other possible factors that might skew the data. Some of the research also separated participants further by age and gender.
Findings for all-cause mortality (ACM [death from any cause]) for those with TC between 200-240 mg/dL had the lowest incidence. The rate of death increased the TC went down below 199 mg/dL (are you seeing a trend yet?). Interestingly enough, the American Heart Association, the journal's parent organization, say that total cholesterol should be below 200 mg/dL. This is the range that has been demonstrated by the AHA to increase risk death from all causes. The standard protocol for primary care providers is to prescribe statin medication when TC is above 200 mg/dL which will place patients well within the range of increased risk of death.
There are also other health risks associated with direct effect of statin use in addition to health benefits not associated with TC lowering mechanisms. Statins act on many mechanisms in addition to reducing cholesterol synthesis in the liver. A benefit-risk analysis of statin use will be explored in a future post.
It is safe to say that total cholesterol levels appear safest when they remain in the range between 200-240 mg/dL. This is my target. Unless you have a very rare disease, it is completely controllable through diet which will be discussed later. Don't forget exercise will increase your total cholesterol level (by increasing HDL) as it improves your health.

Some of her pearls of wisdom:
- I don't eat junk food
- I mind my own business
- Fresh fish
- Banana porridge
- Root vegetables (manioc)
- Grilled meat
- She also avoids salt, sugar and processed foods
Another interesting point she made in her interview is that she walks regularly in her village visiting friends and relatives and does not use soap or any artificial products from the city.
Dare I say, this appears to be a very organic lifestyle.

The current trending definition of APN includes all master's and doctorate level educated nurses. According to the (AACN, 2004),
Any form of nursing intervention that influences health care outcomes for individuals or populations, including direct care of individual patients, management of care for individuals and populations, administration of nursing and health care organizations, and the development and implementation of health policy.This modern definition of APN includes nurse educators, public health nurses, nurse administrators, and nursing research. I was surprised to learn APNs are no longer limited to direct clinical care. As far as mandating doctorate level education to the definition of APN, direct clinical care (DNP) and nursing research (PhD) seem to be the only two defined terminal pathways.
The exceptions to the current proposed mandate of doctorate level educated nurses by 2015 appear to be limited to clinical nurse leaders and nurse educators. These two professional arenas are generally accepted at the master's level due to the combination of didactic training and practical experience (Barker, 2009).

Here is the abstract from Medical Hypothesis at Elsevier:
Cutaneous malignant melanoma (CMM) has been increasing at a steady exponential rate in fair-skinned, indoor workers since before 1940. A paradox exists between indoor and outdoor workers because indoor workers get three to nine times less solar UV (290–400 nm) exposure than outdoor workers get, yet only indoor workers have an increasing incidence of CMM. Thus, another “factor(s)” is/are involved that increases the CMM risk for indoor workers. We hypothesize that one factor involves indoor exposures to UVA (321–400 nm) passing through windows, which can cause mutations and can break down vitamin D3 formed after outdoor UVB (290–320 nm) exposure, and the other factor involves low levels of cutaneous vitamin D3. After vitamin D3 forms, melanoma cells can convert it to the hormone, 1,25-dihydroxyvitamin D3, or calcitriol, which causes growth inhibition and apoptotic cell death in vitro and in vivo. We measured the outdoor and indoor solar irradiances and found indoor solar UVA irradiances represent about 25% (or 5–10 W/m2) of the outdoor irradiances and are about 60 times greater than fluorescent light irradiances. We calculated the outdoor and indoor UV contributions toward different biological endpoints by weighting the emission spectra by the action spectra: erythema, squamous cell carcinoma, melanoma (fish), and previtamin D3. Furthermore, we found production of previtamin D3 only occurs outside where there is enough UVB. We agree that intense, intermittent outdoor UV overexposures and sunburns initiate CMM; we now propose that increased UVA exposures and inadequately maintained cutaneous levels of vitamin D3 promotes CMM.
Since UVB sunlight exposure of 15-30 minutes can produce between 15,000 to 30,000 IU of vitamin D3 which is protective against melanoma. We should get outside more frequently. Protect your face and neck with a hat (since this is the most susceptable area of the body due to chronic, long-term exposure), and get an adequate dose of sunlight on a regular basis. DO NOT put on sunscreen when you want to get vitamin D since it blocks UVB exposure of the skin and subsequently vitamin D synthesis.
Vitamin D has been found to act on approximately 2,000 genes in our body and every single cell has at least one vitamin D sensitive receptor/activator in the phospholipid bilayer (cell wall) as noted in ScienceDaily. Think about what that can mean for a moment. Do we really want to be deficient with this hormone? Yes, vitamin D is not a vitamin. It is a hormone that has action in our endocrine system regulating more than we realize. Since vitamin D is one of my personal pet study projects, I plan to study it further.

Dairy, glistening milk, savory butter, thick cream, and satiating cheese. How about the cultured variety, yogurt and keifer? Then, there are fermented curds and whey and don't forget cottage cheese. I eat dairy raw as much as possible with the exception of the occasional heavy whipping cream dosed for my Starbuck's coffee. Did you know that you can leave raw milk out on the counter for three days, consume it, and gain health benefits? I didn't until a few months ago when I learned how to make homemade cottage cheese. The separated whey can be used for fermenting vegetables like sauerkraut.
Why do the vast majority of us avoid raw dairy? Is it because milk has undergone demonization by the dairy industry, FDA, and other authoritative entities under the premise of public health? Is it really that dangerous? Maybe we should ask the Masai tribe. There is plenty of research on these people consuming large amounts raw milk and meat "with little or no evidence of atherosclerosis or heart disease". However one chooses to view this controversy, changing the way humans have consumed dairy for tens of thousands of years has a causal relationship wtih our health.
Milk consumption has undergone dramatic changes in composition and production in the last 200 years. We have moved from milking our own cows and goats to strict oversight of production from the feeding of cattle to dispensing at the store front. Current mechanisms of dairy mass-production may very well be antiquated and more hazardous to our health than consuming raw and unprocessed dairy from small family farms. Yes, one can drink contaminated milk (raw or processed) and get acutely ill. The media coverage is enough to scare anyone into thinking raw milk is akin to poison. Just review the recent news about FDA approved monitored food products 1, 2, 3 and see the inherent dangers associated with governmental regulation of food products in general. A lot of this is new to me and may require revision in the future. In the mean time, I hope to describe some of the basics I've discovered and attribute my newly found health.
How does raw dairy differ from processed dairy (pasteurized, homogenized, or ultra-homogenized)? Here are some of the differences.
1. Pharmaceutical and genetic influences: Coming from pasture raised cows, diary is absent of contaminants from low-grade antibiotic therapy given to feed-lot cows. Recombinant bovine growth hormone (rBGH) and its cumulative effects, in addition to genetically modified feed is also absent. The hormone rBGH stimulates insulin-like growth factor-1 (IGF-1), which is associated with breast, colon, and prostate cancer.
2. Nutritional Attributes: Pasteurization destroys vital enzymes. Many people complain of being lactose intolerance. Milk contains a disaccharide (milk sugar) called lactose. There is an inherent inability in some people breakdown lactose as we age. This may be due to our decreased dependence on milk in early development or there may be other explanations such as a genetic predisposition. What ever the cause, with lactose intolerance our intestinal villi do not secrete enough lactase (an enzyme) to breakdown lactose into monosaccharides, glucose and galactose. Once broken down, glucose gets absorbed into the bloodstream and galactose continues to break down further into glucose for transport, again to the blood.
3. Raw milk also contains bacteria-friendly lactobacilli to that breaks down lactose. Pasteurization destroys this bacteria altering milk composition. So, people who are lactose intolerant are in reality pasteurization intolerant. They can often consume raw dairy products without difficulty, especially fermented dairy since the bacteria digests lactose during fermentation.
4. Phosphatase, an essential enzyme utilized in calcium absorption in conjunction with vitamin D (found in raw cream) is destroyed during pasteurization contributing to decreased mineralization processes needed for continued osteogenesis.
5. Catalase, an anti-oxidizing enzyme is also destroyed in pasteurization. Catalase is used to deactivate hydrogen peroxide and toxins including phenols and alcohols. Combine this with the increased bioavailability resulting from the the activating process (from fractured lipid globules) of Xanthine oxidase (XO), a reactive oxygen species (ROS) synergized in the presence of testosterone has been shown to be atherosclerotic especially for men and the soup for heart disease is beginning to be prepared. During homogenization, fractioning lipid globules can trigger a free-radical cascade potentially stimulating allergic responses, inflammation, and atherosclerosis.
6. Perhaps the least known and most profound benefits come from application of its anti-oncogenic properties. Dr. Burzinski, a physician and scientist, currently doing multiple FDA phase II clinical trials extracted four antineoplaston (ANP) ingredients from whey, milk, feta and farmer's cheese that have been shown to deactivate oncogenes and activate tumor suppressor genes. They are 3-phenylactylamino-2, 6-piperidinedione, phenylacetylglutamine, and phenylacetylisoglutamine. If you want to learn about his research of treating cancer a documentary can be found here. This anti-cancer therapy is generally considered more effective and less toxic than both chemotherapy and radiation treatment.
