Satchidananda Panda, Ph.D., is a leading researcher in a very important field of study: the circadian rhythm, which is the topic of his book, “Circadian Code: Lose Weight, Supercharge Your Energy and Sleep Well Every Night.” It’s a great read, written at a level that is easy to understand.

Growing up on a farm in India, he was initially intrigued by the fact that he slept best during the summertime. Then, going through agricultural school, he realized that different plants flower at certain times of the day.

“A few years later, when I was thinking about grad school, I realized there are so many things about biology of time,” Panda says. “Every biological system depends on time; just like throughout the day we have a clear timetable when we should be doing this and that — meeting people and having conversation and having dinner.

Every organism has that [but] we haven’t learned the biology of time. That’s why I got excited about circadian rhythms, because this is a universal timing system, starting from pond scum to humans … Every organism has to go through this 24-hour timing schedule.

If this is disrupted, then plants will flower at the wrong time and animals will not reproduce well. In humans, lots of different diseases can happen. That’s why I got excited about circadian rhythms and got into my Ph.D. Now I’m at the Salk Institute, a nonprofit research organization in San Diego, California.”

Circadian Rhythms Are Under Genetic Control

Last year, the Nobel Prize in Physiology or Medicine was awarded to three U.S. biologists — Jeffrey Hall, Michael Rosbash and Michael Young — for their discovery of master genes that control your body’s circadian rhythms.1,2,3,4,5 Panda explains:

“The bottom line is almost every cell in our body has its own clock. In every cell, the clock regulates a different set of genes, [telling them] when to turn on and [when to] turn off.

As a result, almost every hormone in your body, every brain chemical, every digestive juice and every organ that you can think of, its core function rises and falls at certain times of the day [in a coordinated fashion].

For example, your growth hormone might rise in the middle of the night, in the middle of sleep. At the same time, if there is not [too much] food in your stomach, then the stomach lining will start to repair. For that repair to work perfectly, the growth hormone from the brain has to coincide with the stomach repair time.

In that way, different rhythms in different parts of our body have to work together for the entire body to work optimally. In fact, to have these daily rhythms and sleep-wake cycle, being more alert in the morning, having the bowel movement at the right time, having better muscle tone in the afternoon, these rhythms are the fountain of health. That’s the indication of health.”

Shift Work Disrupts Your Circadian Rhythm

The idea that you could possibly micromanage this intricately timed system from the outside is foolish in the extreme. As Panda notes in his book, the key, really, is to pay attention to and honor ancient patterns of waking, sleeping and eating.6 By doing that, your body more or less takes care of itself automatically.

“Yes, to leverage these daily rhythms that are so ingrained in our body, we just have to do a few things: sleep at the right time, eat at the right time, and get a little bit of bright light during the daytime. That’s the foundation. We can do very simple things to reap the benefits of the circadian rhythm and the wisdom of our body,” Panda says.

One of the most common circadian anomalies in today’s modern world is shift work. If you’re like me, you might be under the misconception that it’s a relatively small minority of people that engage in this activity, but Panda cites research showing a full 20 to 25 percent of the American nonmilitary workforce disrupt their natural circadian rhythm by working nights.

In his book, shift work is defined as any work that requires you to stay awake for three hours or more between 10 p.m. and 5 a.m. for more than 50 days a year (basically once a week).

The fact that 1 in 4 is exposed to this circadian rhythm aberration is bad enough, but on top of that there are the health effects of dirty electricity and the unhealthy light spectrum emitted by pulsing light-emitting diodes (LED) and fluorescent lighting, which further exacerbates the problem.

“Only in the last 16 years we have come to understand the impact of light on our health,” Panda says. “Before this, we thought that lighting is only for vision. Our eyes just have retinal cone cells to guide us throughout the world. Sixteen years ago, myself and two others … discovered this blue light-sensing light receptor called melanopsin.

These light-sensing cells in the retina — 5,000 of them per eye — are hardwired to many parts of the brain, including the master clock in the hypothalamus, and the pineal gland that makes … melatonin.

That discovery completely changed how we look at light. It’s not only lighting for safety or security. We have to now think about lighting for health … We [also] have to now think about blue light.

It’s not that we should get rid of blue light completely. We need more blue light during the daytime, and we need less at least three to four hours before going to bed.

The bottom line is in the last 100 to 150 years, we have cleared the man-made world without paying attention to circadian rhythms. Now we have the excellent opportunity to recreate and rebuild this entire world that will optimize our health.”

The Price You Pay for Chronic Sleep Disruption

It’s extremely difficult to estimate the price paid for widespread sleep disruption, but what is known is what happens when you chronically disrupt your circadian rhythm. Panda explains:

“Starting from babies all the way to 100-year-olds, we know that a few nights of staying awake for three to four hours or even eating at the wrong time can cause irritation, foggy brain, mild anxiety, loss of productivity and insomnia.

At the same time, this can flare up underlying autoimmune disease … We can look at shift workers in controlled clinical studies. When we make a list of diseases that circadian rhythm disruption contributes to, it’s a huge list.

It goes from mental health issues such as depression, anxiety, bipolar disease, attention-deficit hyperactivity disorder, autism spectrum disorder and post-traumatic stress disorder [to] obesity, diabetes, cardiovascular disease and fatty liver disease …

Many of these affect more than 10 percent of the population. And then you bring in gastrointestinal diseases: irritable bowel syndrome, irritable bowel disease, and even heartburn and ulcerative colitis.

If you combine all of these, then we can see clearly why nearly one-third of all adults in the U.S. have one or more of these chronic diseases, more than two-thirds of adults at the age of 45 have some of these chronic diseases. Nine out of 10 at the age of 65 have two or more of these chronic diseases.

Now, the question is, ‘How much of this is due to circadian rhythm disruption and other factors, or maybe circadian rhythm disruption with underlying genetic cause?’ We cannot come up with a clear figure, but it’s very clear that if we optimize circadian rhythm, we can really move the needle.”

Sleep Deprivation Induces Glucose Intolerance in as Little as Four Days

Research by Eve Van Cauter, director of the Sleep, Metabolism and Health Center at the University of Chicago, also shows that sleeping less than six hours a night dramatically increases your risk of insulin resistance, which is at the core of most chronic diseases, including those mentioned above. There’s actually a daily rhythm in insulin sensitivity.

For example, if you do a glucose tolerance test in the morning, it may be normal, but done in the evening, it may suggest you have prediabetes. She also showed that when otherwise healthy people are deprived of sleep and allowed to sleep only five hours or less per night, they develop glucose intolerance in as little as four days. As noted by Panda:

“That’s really eye-opening. Because many of us go through that kind of disruption on a monthly or weekly basis. Shift workers go through that half of their life. That might explain the rise in glucose intolerance and having 85 million prediabetics in [the U.S.].”

Melatonin Production and Sleep Disorders

In his book, Panda discusses how melatonin production changes with age. With increasing age, melatonin production starts going down such that a 60-year-old may produce one-tenth the melatonin of a 10-year-old. As noted by Panda, reduced melatonin production is at the heart of many sleep disorders seen in the elderly.

So, how can you optimize your melatonin production as you age? One common solution is to take a melatonin supplement. Melatonin receptor agonist drugs are also available. However, a simpler solution that anyone can do, which costs nothing, is to control your lighting.

“Just imagine, 150 years ago, the firelight, the lamplight or even the full moon light was only 1 to 5 lux. Full moon light is maximum 1 lux. Now, we have 50 to 100 lux. In some department stores you can get 600 to 700 lux of light in the evening. That’s a tremendously high amount of light. That would slam your melatonin [production] down to almost zero,” Panda says.

Ideally, replace LEDs and fluorescent light bulbs in key areas where you spend time in the evening with low-watt incandescent bulbs, and avoid electronic screens for a few hours before bedtime.

An alternative is to wear blue-filtering eyeglasses at night. Just make sure don’t wear them during daytime. Also, make sure the glasses filter out light between 460 to 490 nanometers (nm), which is the range of blue light that most effectively reduces melatonin. If they filter everything below 500 nm, you should be good to go.

The Importance of Meal Timing

Panda has also investigated the impact of meal timing on circadian rhythm. Just like many cleanout functions occur in your brain during deep sleep, all other organs also need downtime. Many organs actually need between 12 and 16 hours of rest, meaning a minimum of 12 hours without food, to allow for repair.

In time-restricted feeding trials, Panda has shown that mice whose feedings are restricted to a window of eight to 12 hours are protected from obesity, diabetes, cardiovascular disease, systemic inflammation, high cholesterol and a host of other diseases. This, despite the fact they’re eating the same amount of calories and the same type of food as animals allowed to graze throughout the day and night.

More importantly, when fat mice are placed on an eight- to 10-hour time-restricted feeding schedule, many of these diseases can be reversed. Human trials suggest the same results can be obtained in humans who adopt a time-restricted eating schedule where all food is eaten within a window of eight to 10 hours.

According to Panda, at bare minimum, you should fast for 12 hours a day — that’s eight hours of sleep, plus three hours of fasting before bed, plus another hour in the morning, to allow your melatonin to level off. At 12 hours of fasting per day, you will maintain your health, but you’re unlikely to actually reverse disease. For that, you need to fast longer.

“The question is how short one can go. This is where there is some limitation in doing controlled studies like we do on animals, where we can do this for a long period of time, because if you reduce access to food for less than six hours in many animals, they will reduce their caloric intake.

So, then we cannot figure out whether the benefit or harm we are seeing is due to the reduction in calories or reduction in timing,” Panda says.

The way I look at it, 12-hour time-restricted eating is something everybody should do. It’s like brushing your teeth every day. What is surprising is only 10 percent of the population consistently eat within 12 hours … [Then] once every six months or once a year, [go down to] eight-hour eating for a month or so.”

There’s an App for That

Panda has developed a very helpful free app, available on Android and iOS, called myCircadianClock. By using this app, you will contribute to Panda’s circadian research.

“We ask people to self-monitor themselves for two weeks, because we know their weekdays and weekends might be different. We just want to get a broader picture of what is your lifestyle from one day to another. And then after two weeks, people can self-select whether they want to eat all their food within 10 hours, 12 hours or eight hours.

You’re free to do whatever you want to do … Over a long period of time, we can figure out what is good or bad for people. In this new app, you can log your food. It also has other bells and whistles. The app can be paired with your Google Health or Apple Health Kit. It can extract your step count, sleep, et cetera. …

After 12 weeks, we also want you to enter your body weight. If you have been collecting lots of other health data, then it’s good to enter that. That’s how it will help to figure out, at the epidemiological level, in real life situations, what our habits are and how we can change it.

The same app is being used in many controlled clinical studies. There are nearly 10 different studies going on in different parts of the world that use the same app … In that way, we can benefit from a controlled study as we launch this large open-to-all kind of studies.”

According to Panda, most people will notice improvements in their sleep within two to three weeks of time-restricted eating. Symptoms of heartburn will also typically begin to resolve. Between weeks four and six, daytime energy levels typically increase while evening hunger pangs are reduced.

Between six to 12 weeks, people with prediabetes or diabetes will begin to see improvements in fasting blood glucose. Those with mild hypertension also tend to notice improvements at this time, as do those with irritable bowel syndrome, as the microbiome improves and the gut begins to repair.

“Once the gut repair improves, then systemic inflammation goes down. Between eight to 12 weeks, that’s when a lot of people report that their joint pain goes down, because that’s a good sign of inflammation.

Once in a while, we get random reports. For example, some people who have inflammatory disease or autoimmune disease, they sometimes say the severity has gone down,” Panda says.

On NAD and Circadian Rhythm

Nicotinamide adenine dinucleotide (NAD+) — one of the most important metabolic coenzymes in your body that helps redox balance and energy metabolism — is primarily generated through a salvage pathway rather than de novo or building NAD+ from scratch pathway.

The rate-limiting enzyme is nicotinamide phosphoribosyltransferase (NAMPT), which is also under circadian control. When your circadian rhythm gets disrupted, it causes NAMPT impairment. NAMPT also helps set the circadian rhythm. In short, by optimizing your circadian rhythm, you’re going to optimize your NAD production. Panda explains:

“Studies say it goes both ways, because NAD also affects sirtuins, and sirtuins integrate with circadian rhythm. Nicotinamide adenine dinucleotide phosphate (NADPH) ratio also affects your [circadian] clock and transcription factors bind to DNA.

The bottom line that we have seen with circadian rhythm is if the clock regulates something, then there is a reciprocal feedback regulation from that output into the clock. That’s the best way you can clear the homeostatic system. It’s the chicken and egg story.”

Sweet! Here are 7 reasons to eat sweet potatoes

Editor

Published

on

By

(Natural News) Sweet potatoes may not be as popular as regular potatoes, which is too bad — since they’re packed with vitamins and minerals. One cup of sweet potatoes can provide more than 100 percent of the daily value of vitamin A. It’s also rich in vitamin C, dietary fiber, and manganese. Both purple and orange varieties contain antioxidants that can protect the body from damage caused by free radicals.

Eating sweet potatoes is beneficial for your health

Sweet potatoes are brimming with micronutrients and antioxidants —  making them useful to your health. Below is a list of reasons why you should incorporate sweet potatoes into your diet.

They improve brain function

The purple variety of sweet potato contains anthocyanins. Anthocyanins are known for their anti-inflammatory properties. Studies have revealed that anthocyanins are effective at improving cognitive function. Moreover, the results suggest that purple yams can help protect against memory loss. Antioxidants from the purple variety safeguard the brain against damage from free radicals and inflammation.

They aid digestion

Sweet potatoes are rich in dietary fiber. This macronutrient prevents constipation, diarrhea, and bloating by adding bulk and drawing water to the stool. In addition, fiber keeps a healthy balance in the gut by promoting the growth of good bacteria.

They slow down aging

The beta-carotene in orange sweet potatoes can help reduce damage caused by prolonged sun exposure. This is especially true for people diagnosed with erythropoietic protoporphyria and other photosensitive diseases. Sweet potatoes also contain antioxidants that protect against free radical damage. Free radicals are not only linked to diseases but also premature aging.

They boost the immune system

Orange and purple sweet potatoes are loaded with a good number of antioxidants that help protect the body from harmful molecules that cause inflammation and damage DNA. This, in turn, protects the body from chronic diseases like cancer and heart disease.

They can prevent cancer

Eating sweet potatoes can help protect against various types of cancers. The compounds in sweet potatoes restrict the development of cancer cells. Test tube studies have shown that anthocyanins can prevent cancers in the bladder, breast, colon, and stomach.

They lower blood sugar

Despite its relatively high glycemic index, studies have shown that the regular intake of sweet potatoes can help lower blood sugar, thanks to the presence of dietary fiber. While fiber falls under carbohydrates, it is digested differently, compared to starchy and sugary forms of carbohydrates. Interestingly, insulin doesn’t process fiber (unlike other types which get turned into glucose), and it only passes through the digestive tract.

They promote healthy vision

Orange sweet potatoes are rich in a compound called beta-carotene, an antioxidant which transforms into vitamin A in the body. Adequate intake of vitamin A promotes eye health. Conversely, deficiencies in vitamin A have been linked to a particular type of blindness called xerophthalmia.

Sweet potatoes are easy to incorporate into your everyday meals. They are best prepared boiled but can also be baked, roasted, or steamed — they can even replace other carbohydrates such as rice, potatoes, and toast.

Frostbite: What it is and how to identify, treat it

Editor

Published

on

By

Manitoba’s temperature has plummeted to its coldest level this season, triggering warnings about the extreme risk of frostbite.

Oh, we know it’s cold. We can feel Jack Frost nipping at our noses. But what about when he gnaws a little harder — what exactly does “frostbite” mean?

People tend to underestimate the potential for severe injuries in the cold, says the Winnipeg Regional Health Authority. We laugh off the sting of the deep freeze, rub our hands back from the brink of numbness and wear our survival proudly like a badge.

That’s because, in most cases, frostbite can be treated fairly easily, with no long-term effects.

But it can also lead to serious injury, including permanent numbness or tingling, joint stiffness, or muscle weakness. In extreme cases, it can lead to amputation.

Bitter cold can cause frostbite in just minutes. Here’s how to recognize the warning signs and treat them. 0:59

Here’s a guide to identifying the first signs, how to treat them, and when to seek medical help.

What is frostbite and frostnip?

Frostbite is defined as bodily injury caused by freezing that results in loss of feeling and colour in affected areas. It most often affects the nose, ears, cheeks, chin, fingers or toes — those areas most often exposed to the air.

Cooling of the body causes a narrowing of the blood vessels, slowing blood flow. In temperatures below –4 C, ice crystals can form in the skin and the tissue just below it.

Frostnip most commonly affects the hands and feet. It initially causes cold, burning pain, with the area affected becoming blanched. It is easy to treat and with rewarming, the area becomes reddened.

Frostbite is the acute version of frostnip, when the soft tissue actually freezes. The risk is particularly dangerous on days with a high wind chill factor. If not quickly and properly treated, it can lead to the loss of tissues or even limbs. 

Signs of frostbite

Health officials call them the four P’s:

  • Pink: Skin appears reddish in colour, and this is usually the first sign.
  • Pain: The cold becomes painful on skin.
  • Patches: White, waxy-feeling patches show when skin is dying.
  • Prickles: Affected areas feel numb or have reduced sensation.

Symptoms can also include:

  • Reduced body temperature.
  • Swelling.
  • Blisters.
  • Areas that are initially cold, hard to the touch.

Take quick action

If you do get frostbite, it is important to take quick action.

  • Most cases of frostbite can be treated by heating the exposed area in warm (not hot) water.
  • Immersion in warm water should continue for 20-30 minutes until the exposed area starts to turn pink, indicating the return of blood circulation.
  • Use a warm, wet washcloth on frostbitten nose or earlobes.
  • If you don’t have access to warm water, underarms are a good place to warm frostbitten fingers. For feet, put them against a warm person’s skin.
  • Drink hot fluids such as hot chocolate, coffee or tea when warming.
  • Rest affected limbs and avoid irritation to the skin.
  • E​levate the affected limb once it is rewarmed.

Rewarming can take up to an hour and can be painful, especially near the end of the process as circulation returns. Acetaminophen or ibuprofen may help with the discomfort.

Do not …

There are a number of things you should avoid:

  • Do not warm the area with dry heat, such as a heating pad, heat lamp or electric heater, because frostbitten skin is easily burned.
  • Do not rub or massage affected areas. This can cause more damage.
  • Do not drink alcohol.
  • Do not walk on your feet or toes if they are frozen.
  • Do not break blisters.

Seek immediate medical attention

While you can treat frostbite yourself if the symptoms are minor — the skin is red, there is tingling — you should seek immediate medical attention at an emergency department if:

  • The exposed skin is blackened.
  • You see white-coloured or grey-coloured patches.
  • There is severe pain or the area is completely numb.
  • The skin feels unusually firm and is not sensitive to touch after one hour of rewarming.
  • There are large areas of blistering.
  • There is a bluish discolouration that does not resolve with rewarming.

Be prepared

The best way to avoid frostbite is to be prepared for the weather in the first place.

Wear several loose layers of clothing rather than a single, thick layer to provide good insulation and keep moisture away from your skin.

The outer garment should breathe but be waterproof and windproof, with an inner thermal layer. Retain body heat with a hat and scarf. Mittens are warmer than gloves because they keep the fingers together.

Be sure your clothing protects your head, ears, nose, hands and feet, especially for children.

Wind chill and frostbite rates

Wind chill: 0 to –9.
Frostbite risk: Low.

Wind chill: –28 to –39.
Frostbite risk: Moderate.

Exposed skin can freeze in 10-30 minutes

Wind chill: –40 to –47.
Frostbite risk: High.

Exposed skin can freeze in five to 10 minutes.

Wind chill: –48 to –54.
Frostbite risk: Very High.

Exposed skin can freeze in two to five minutes.

Wind chill: –55 and lower.
Frostbite risk: Extremely High.

Exposed skin can freeze in less than two minutes.
 

NOTE: In sustained winds over 50 km/h, frostbite can occur faster than indicated.

Awkward Flu Jabs Attempted at Golden Globes

Editor

Published

on

By

In what can only be described as a new level of propaganda, hosts Andy Samberg and Sandra Oh featured a flu shot stunt during the 76th Golden Globe Awards ceremony. They told the audience to roll up their sleeves, as they would all be getting flu shots, while people in white coats stormed down the aisles, syringes in hand.

Most of the audience looked thoroughly uneasy at the prospect of having a stranger stick them with a needle in the middle of an awards show. But perhaps the worst part of the scene was when Samberg added that anti-vaxxers could put a napkin over their head if they wanted to be skipped, basically suggesting that anyone opposed to a flu shot deserved to be branded with a proverbial scarlet letter.

The flu shots, for the record, were reportedly fake,1 nothing more than a bizarre gag that left many people stunned by the Globe’s poor taste in turning a serious medical choice into a publicity gimmick.

Flu Shot Stunt Reeks of Desperation

Whoever came up with the idea to turn the Golden Globes into a platform for a public health message probably thought it was ingenious, but the stunt only serves as a seemingly desperate attempt to make flu shots relevant and in vogue. During the 2017 to 2018 flu season, only 37 percent of U.S. adults received a flu shot, a 6 percent drop from the prior season.2

“To improve flu vaccination coverage for the 2018-19 flu season, health care providers are encouraged to strongly recommend and offer flu vaccination to all of their patients,” the U.S. Centers for Disease Control and Prevention (CDC) wrote. “People not visiting a provider during the flu season have many convenient places they can go for a flu vaccination.”3

Yet, perhaps the decline in people choosing to get vaccinated has nothing to do with convenience and everything to do with their dismal rates of efficacy. In the decade between 2005 and 2015, the influenza vaccine was less than 50 percent effective more than half of the time.4

The 2017/2018 flu vaccine was a perfect example of this trend. The overall adjusted vaccine effectiveness against influenza A and B virus infection was just 36 percent.5

Health officials blamed the flu season’s severity on the dip in vaccination rates, but as Dr. Paul Auwaerter, clinical director of the division of infectious diseases at Johns Hopkins University School of Medicine, told USA Today, “[I]t is also true that the vaccine was not as well matched against the strains that circulated.”6

But bringing flu shots to the Golden Globes, and calling out “anti-vaxxers,” is nothing more than “medical care, by shame,” noted Dr. Don Harte, a chiropractic activist in California. “But it was entertaining, in a very weird way, including the shock and disgust of some of the intended victims, notably [Willem Dafoe],” he said, adding:7

“This Hollywood publicity stunt for the flu vaccine is one of the stupidest things I’ve ever seen from celebrities. But it does go with the flu shot itself, which is, perhaps, the stupidest of all the vaccines available.”

Did 80,000 People Really Die From the Flu Last Year?

The CDC reported that 79,400 people died from influenza during the 2017/2018 season, which they said “serves as a reminder of how severe seasonal influenza can be.”8 It’s important to remember, however, that the 80,000 deaths figure being widely reported in the media is not actually all “flu deaths.”

According to the CDC, “We look at death certificates that have pneumonia or influenza causes (P&I), other respiratory and circulatory causes (R&C), or other nonrespiratory, noncirculatory causes of death, because deaths related to flu may not have influenza listed as a cause of death.”9

As for why the CDC doesn’t base flu mortality estimates only on death certificates that list influenza, they noted, “Seasonal influenza may lead to death from other causes, such as pneumonia, congestive heart failure or chronic obstructive pulmonary disease … Additionally, some deaths — particularly among the elderly — are associated with secondary complications of seasonal influenza (including bacterial pneumonias).”10

In other words, “flu deaths” are not just deaths directly caused by the influenza virus, but also secondary infections such as pneumonia and other respiratory diseases, as well as sepsis.11

According to the CDC, most of the deaths occurred among those aged 65 years and over, a population that may already have preexisting conditions that makes them more susceptible to infectious diseases. As Harte said of annual flu deaths, “[M]ost if not all, I would assume, are of people who are already in very bad shape.12

CDC Claims Flu Vaccine Reduces Flu Deaths in the Elderly — But Does It?

Since people aged 65 and over are those most at risk from flu complications and death, the CDC has been vocal in their claims that the flu shot significantly reduces flu-related deaths among this population. The research, however, says otherwise.

Research published in 2005 found no correlation between increased vaccination rates among the elderly and reduced mortality. According to the authors, “Because fewer than 10 percent of all winter deaths were attributable to influenza in any season, we conclude that observational studies substantially overestimate vaccination benefit.”13

A 2006 study also showed that even though seniors vaccinated against influenza had a 44 percent reduced risk of dying during flu season than unvaccinated seniors, those who were vaccinated were also 61 percent less like to die before the flu season ever started.14

This finding has since been attributed to a “healthy user effect,” which suggests that older people who get vaccinated against influenza are already healthier and, therefore, less likely to die anyway, whereas those who do not get the shot have suffered a decline in health in recent months.

Journalist Jeremy Hammond summed up the CDC’s continued spreading of misinformation regarding the flu vaccine’s effectiveness in the elderly, as they continue to claim it’s the best way to prevent the flu:15

[T]here is no good scientific evidence to support the CDC’s claim that the influenza vaccine reduces hospitalizations or deaths among the elderly.

The types of studies the CDC has relied on to support this claim have been thoroughly discredited due to their systemic ‘healthy user’ selection bias, and the mortality rate has observably increased along with the increase in vaccine uptake — which the CDC has encouraged with its unevidenced claims about the vaccine’s benefits, downplaying of its risks, and a marketing strategy of trying to frighten people into getting the flu shot for themselves and their family.”

Death of Vaccinated Child Blamed on Not Getting Second Dose

In January 2019, the state of Colorado reported the first child flu death of the 2018/2019 flu season — a child who had received influenza vaccination. But instead of highlighting the vaccine’s failure and clear limitations, the Colorado Department of Public Health and Environment blamed the death on the child being only “partially vaccinated.”

“It’s an unfortunate but important reminder of the importance of two doses of influenza vaccine for young children who are receiving influenza vaccine for the first time,” Dr. Rachel Herlihy, who is the state communicable disease epidemiologist, said in a news release.16 For those who aren’t aware, the CDC notes that one dose of flu shot may not be enough to protect against the flu. Instead, they state:17

“Children 6 months through 8 years getting vaccinated for the first time, and those who have only previously gotten one dose of vaccine, should get two doses of vaccine this season …

The first dose ‘primes’ the immune system; the second dose provides immune protection. Children who only get one dose but need two doses can have reduced or no protection from a single dose of flu vaccine.”

Not only may the flu vaccine fail to provide protection against the flu, but many people are not aware that other types of viruses are responsible for about 80 percent of all respiratory infections during any given flu season.18 The flu vaccine does not protect against or prevent any of these other types of respiratory infections causing influenza-like illness (ILI) symptoms.

The chance of contracting actual type A or B influenza, caused by one of the three or four influenza virus strains included in the vaccine, is much lower compared to getting sick with another type of viral or bacterial infection during the flu season.

Does Flu Vaccine Increase the Risk of Influenza Infection, Contribute to Vaccine Shedding?

There are serious adverse effects that can come along with annual flu vaccination, including potentially lifelong side effects such as Guillain Barré syndrome and chronic shoulder injury related to vaccine administration (SIRVA). They may also increase your risk of contracting more serious flu infections, as research suggests those who have been vaccinated annually may be less protected than those with no prior flu vaccination history.19

Research presented at the 105th International Conference of the American Thoracic Society in San Diego also revealed that children who get seasonal flu shots are more at risk of hospitalization than children who do not. Children who had received the flu vaccine had three times the risk of hospitalization as children who had not. Among children with asthma, the risk was even higher.20

There’s also the potential for vaccine shedding, which has taken on renewed importance with the reintroduction of the live virus vaccine FluMist during the 2018/2019 season. While the CDC states that the live flu virus in FluMist is too weak to actually give recipients the flu, research has raised some serious doubts that this is the case.

One recent study revealed not only that influenza virus may be spread via simple breathing (i.e., no sneezing or coughing required) but also that repeated vaccination increases the amount of virus released into the air.21

MedImmune, the company that developed FluMist, is aware that the vaccine sheds vaccine-strain virus. In its prescribing information, they describe a study on the transmission of vaccine-strain viruses from vaccinated children to nonvaccinated children in a day care setting.

In 80 percent of the FluMist recipients, at least one vaccine-strain virus was isolated anywhere from one to 21 days following vaccination. They further noted, “One placebo subject had mild symptomatic Type B virus infection confirmed as a transmitted vaccine virus by a FluMist recipient in the same playgroup.”22

Are There Other Ways to Stay Healthy During Flu Season?

Contrary to the CDC’s and Golden Globe’s claims that flu vaccinations are a great way to prevent flu, other methods exist to help you stay healthy during the flu season and all year, and they’re far safer than annual flu vaccination. Vitamin D testing and optimization have been shown to cut your risk of respiratory infections, including colds and flu, in half if you are vitamin D deficient, for instance.23,24
