Disease Increases: Has the West's Health Really Improved?

CDC Wonder is an interesting tool to play with. It's an online US data base that collects data on the environment, population heath, births, and deaths. You can create tables or graphs, specifying by year, age, location etc. For instance, using this tool you can ascertain the mortality rate of certain diseases, and get an idea of how those diseases have risen or fallen over time. Which is exactly what I did. What I found was huge growth in particular of mortality for neurological or autoimmune diseases. These are usually chronic diseases, that progressively get worse over a period of years, as opposed to a sudden onset infection that can kill within days or weeks. The results were very startling, and my mind raced to think of all the different factors that have changed over time that could account for this huge rise in disease. My first thought was neurotoxic substances such as aluminium, mercury, fluoride. Make of it what you will.

Straight From the Mama's Mouth: Advice on Fussy / Gassy Babies

Very often women bring up gassy / fussy baby issues on Beautiful Breastfeeding's Facebook page (Natural Mama NZ's sister site). Mothers pour in with helpful advice, sharing what has worked for them personally. For me this is the best advice and it's one of crowning achievements of motherhood support pages on Facebook. Because gassy / fussy baby  issues keep coming up on Beautiful Breastfeeding and other motherhood pages I thought I'd collate some of the great advice shared through various threads into a blog post. Enjoy...

Check the Latch
"Have you had your latch checked? It's more likely a latch issue than a milk issue; if your latch is slightly off he may be swallowing large amounts of air and he will get very uncomfortable from this."

Burp More Often
"Burp your baby mid-feed. Makes a world of difference with gassy barfy babies."
"Burp more throughout day not just around feedings. Also try burping before feeds. Check out Dunstan baby language."

Try Different Positions
"If you walk around with them tummy down on your forearm, head resting in the nook of your arm. I found this position helped them get through it. And sucking makes their guts move so nurse him. Even if he’s fighting it and cranky...it will help it move through."
"Holding upright after feeding helps, as does gas drops and gripe water. The best thing I've found are what I call “fartercise”. Bicycling wasn't enough I have to gently stretch his legs up until his feet touch his face. GENTLY I stress. And I start with knees bent and gentle pressure towards his tummy and work my way up. It was the only way I could get him some relief. Now he giggles the whole time I do it but as he's getting older he is able to take care of most of it himself."
"I had gassiness / fussiness problems with my daughter, what I did was to hold her up for an hour or more after each breast feed! Now she's two months and she is better, baby needs time to adjust with everything."

 Baby Massage
"Before cycling baby’s legs get some lotion and do the "I love you" massage (google it) and instead of doing JUST his legs lift his body up and slowly roll it back down, like you would do if you were stretching your back. Doing that gets so much more gas out."
"Along with bicycling baby's legs, I would do infant massage on tummy. Worked like a charm with mine."

Babywearing
"Carrying in a sling/wrap close to you is worth trying."
"My little guy had similar issues, so I would burp him after 10 min or so. I also wore him everywhere, and the movement helped him a lot. In the Moby wrap I would bounce-walk and it would calm him down when he was screaming in pain."
"I wear my baby in a Sleepywrap for most of the day and he is so comfortable, he just sleeps, and wakes when he's hungry."

Probiotics
"You can give your baby their own probiotics. It's the only thing that helped my daughter when she had gassiness / fussiness around the same age. We used BioGaia."
"Probiotics helped my son so much. We used Flora Baby."
"I give my baby probiotics! Works great! You can get it at any health food store!"
"You can buy Florajen probiotics for baby." 
"I highly recommend probiotics for your baby too! I started giving them to my baby girl when she was 8 weeks for gassiness / fussiness and they worked very fast. I've been giving them to her ever since and she's never had any GI problems. They're very good for immunity and overall health (I've been working on probiotic research in different diseases for the last 8 years). Hope he feels better soon!"

Change Your Diet
"Could be what you are eating... when I made some changes in my diet I saw a wonderful improvement in my baby."
"Write down what eat! I found out I can't have pepperoni at all my daughter gets gas and stomach ache so bad."
"I chose to cut out many things and it works for me. Some are ok with onions, garlic, soy, dairy, gassy veggies, corn and red meat, some are not. In order to know, you have to cut it out COMPLETELY for a couple of weeks."
"I had to cut all dairy and gluten and it made a HUGE difference."
"My youngest had an issue with me consuming any caffeine."
"Hot sauce hurt my little guy's tummy too."
"What about broccoli? Gave mine gas something fierce."
"I had to eliminate caffeine, peppers, and dairy from my diet."
"Cutting out dairy and other "gassy" foods completely was the only thing that helped us. My baby did grow out of it by about three months except for large amounts of dairy. Goodluck!"
"Try the elimination diet. It takes at least 3 weeks of total elimination from your diet for diary to get out of your system and see results that are consistent."
"If diary is the problem ALL dairy has to be avoided if it is supposed to work. Any dairy will elicit an adverse response in an infant that is allergic or sensitive to dairy (even hidden diary like casein). Same goes for soy and wheat. Please read this: http://kellymom.com/health/baby-health/food-sensitivity/ Also, if you consider cutting dairy altogether, this list may be helpful: http://www.godairyfree.org/dairy.../dairy-ingredient-list-2 See also here: http://kellymom.com/parenting/parenting-faq/gassybaby/ Take care x"
"Have you tried cutting all soy out of your diet? Could be egg allergy, too."
"Watch the onions, garlic, peppers, beans, broccoli and cabbage. I know it's tricky getting your feet on solid ground, but you will get there! And it's SO worth it!"
"Gluten could definitely be a culprit. Cut gluten containing foods front your diet (pay as much as you can attention to all products labels, it can hide anywhere) just for few days and see what' s new in his status. Take care!"
"Watch out for certain seasonings too. All I can eat is salt on my food. Only veggies are corn and squash too. It's worth it as no screaming baby! Oh and no soy either, even soy oil or lecithin... which is in chocolate!"
"My daughter was like this and it turns out she is cows milk protein intolerant. This meant I couldn't have any dairy or soya in my diet - none at all. It takes a month to get out of your system so you have to be patient, but it definitely worked for us. She's now 20 months and still has a dairy and soya free diet. Could be worth a try."

Foremilk / Hindmilk Imbalance
"What are his poops like? If green and lettuce like, you may have a foremilk/hind milk imbalance....baby may not be getting the full day milk that comes toward the end of a feeding session."
"It may be a foremilk and hindmilk imbalance, try to make sure he feeds at least 25 mins both sides. Lots of good energy, you can do it!"
"We had this issue ourselves! For us it had nothing to do with what we were eating, or when I breastfed. My baby was getting too much of the start of the breast milk that is like skim milk, and not enough of the cream at the end of the feeding. If this is your issue, feed on one side until that breast is completely empty. Even if the baby stops because it's full, start again on that same side the next time until it is empty. This way the baby gets all the digestive enzymes that are in the thicker milk to help them digest the skim. We fixed that problem in 24 hours doing that. We sure had a lot of crap advice to the contrary though. Hang in there!"
"How long is your baby nursing on one side?...If he is a quick nurser he could be getting too much foremilk. Foremilk has a lot of lactose in it when that lactose mixes with his little intestines it is painful. And creates a colicky acting baby. Try nursing on one side for a block if time. Each time in that block baby nurses go to the same side, don't switch. When the block is over do the same on the other side. Good luck!"
"Try feeding on one side only. My little guy was getting horrible gas from too much foremilk. Once I started nursing him on just one side it helped tremendously. I pumped out the other to keep my supply up. Around eight weeks it all changes a lot anyway. Stick it out mama! You're doing a great job!"

Forceful Letdown
"When my daughter had that problem our issue ended up being my letdown was too much for her to handle and caused her to take in air. We switched nursing positions to one where she sat upright while nursing and this worked out great for us."

Reflux
"It may be reflux. My son has it. He just takes reflux medication and keeps on breastfeeding."
"You could ask your doctor to give you acid reflux meds and if the problem is reflux it will all go away within days. It worked for all 3 of my children. After weeks of crying with my first. Acid reflux is common in children whether breastfed or bottle fed. So if the problem is reflux, changing to formula will not fix this problem at all, the baby will still be fussy and upset."
"Might be acid reflux, try Ranitidine. Get it from your doc. That is what my baby had and it worked. He had the same symptoms."

It Gets Better With Time
"Time will solve it, some babies are gassy and colicky but this won't last forever!
Don’t give up because it is just a stage!"
"My pediatrician said baby’s guts "wake up" at around 4-6 weeks and they are just fussy and gassy for a little while."
"Some babies might just have a rougher time getting their digestion up and running smoothly. Baby will make it promise."
"Gas starts going away around 2 months old. My baby just smiles and farts now when it was so bad at first."
"We went through gassiness / fussiness with my daughter (now nearly 8mo). It was a rough 6 weeks but after that she was much better."
"ALL my babies (4) went and are going (3weeks old) through a period of gassiness / fussiness. I honestly think it is just their guts adjusting to life on the outside. I nursed them all until after 2 years old including my 21 month old I am still nursing along with the 3 week old."
"Both my babies always seemed in pain with gas, grunted, cried, and struggled...but breast feeding helped them push through it. It does and will pass as he grows, it may seem like it takes them forever to do so, but it will happen. Keep on breast feeding!"
"It will go away, mine went through a gassy phase at 6 weeks and it was gone around 8 weeks or so."
"My son had colic for the first three months of his life. He was our first baby and it broke our hearts to see him in such pain. He cried constantly and so did I. Everyone I knew (and didn't know) commented on his colic and many insisted I switch to formula. I refused and nursed him for the first three years of his life. I have absolutely no regrets about this decision. He was a very high needs baby who was and still is super sensitive but today he is an amazing 5 year old."
"I nursed, held and wore him constantly as a baby and I truly believe this attachment parenting created the foundation for a remarkable and confident young boy. Good luck to you, follow your heart and try to remain positive. His colic will decrease with age and you too can experience an incredible relationship together particularly with breast feeding."
"Both my babies were gassy in the beginning. What I can say is that by 12 weeks it disappeared completely, it's just that until then their tummies are incapable of digesting properly. Hang in there, I promise it passes."

Medication
"They say breastfed babies don't get colic but mine did, it was awful, but once we started colic drops it settled down."
"Baby Gerber Colic Drops. I didn’t believe in it til I tried the drops."
"Simethicone is good - it gathers all the air in the tummy just ingested with a feed, and it all gets burped up in one glorious burp! After a day of this, the colic settles down a lot as those tiny air bubbles never made it into the intestines. My son is 12 weeks and had a lot of colic. I started giving him simethicone a few weeks ago and it's made a difference."
"Mylicon works for my son."
"I had to give my baby Levsin (Hyoscyamine) and it worked wonders!"
"I used to use Infacol drops before each feed which helped."
"My baby was really gassy the first month or so too. I used the target brand gas drops. It worked better than the gripe water. And it tastes way better."
"Colief definitely."
"Try Little Remedies: Little Tummies. Both of my kids used it."
"My son is 7 weeks old and went through this the first 6 weeks. He has reflux and now is on a PPI medication and I give him gas drops Colic Calm he is a whole different baby! It’s truly trial and error! good luck momma!"
"I got stuff called Colic Calm at Walgreens and I'll tell you what IT WORKS! Invest in some!
"Try a product called Iberogast it's an amazing herbal product that is great for wind, colic and reflux."
"My son was very gassy and the only thing that worked was Ovol."
My daughter responded well to a little chamomile tea! I'd breastfeed then give her a couple tablespoons of tea...big burp, big fart and she was happy. Good luck mama" 
"Try cooled fennel tea or homeopathic chamomilla. My boy was the same and they really helped. Health food shops stock chamomilla granules especially for tiny ones."
"My baby had issues with gas and my pediatrician suggested an ounce of prune juice mixed with an ounce of water once a day. Helped my little guy out tons!"
"Buy some carroway seeds and make a tea out of it, you and the baby should drink some, it will help the gas get out!"

Check For Anatomical Problems
"Just make sure that your baby does not have lip or tongue tie that would cause the baby to have a poor latch and get more air when eating. Look at www.kiddsteeth.com to get information about how to check. If you think this is a problem, you can PM me. Good luck! This probably isn't the issue, but I just wanted you to rule it out because it does affect 3-5% of babies."

Chiropractic Care
"My son was diagnosed with GERD and given Zantac. It helped for a few months but he started presenting similar symptoms again. We took him to a chiropractor that diagnosed him with a hiatal hernia. He's been so much better ever since! I suggest looking into a reputable chiropractor that works on infants. And they don't adjust infants the same as adults. My son was on my lap the entire time. Good luck!"
"Chiropractor works miracles for babies! Highly recommend, we dealt with the same issue with my youngest and nothing else helped but the chiropractor. Good luck!"

Try to Avoid Formula
"Worst possible idea is to switch to formula - it will only make things worse as formula is a lot harder on an infant's gut than breast milk. Even just a bottle can cause severe damage to the natural Ph level of his gut. My son was the same, very colicky. I just persisted and he is now 5 months, still breastfeeding and very happy! Don't supplement his milk with anything, and just hang in there. http://www.health-e-learning.com/articles/JustOneBottle.pdf"
"Formula actually gave my daughter much worse gas."
"We tried formula and it made no difference with gas! Only made him constipated."

Helpful Books
"It may have nothing to do with his stomach or the milk. Colic is not always caused by stomach issues. My baby had colic for the first 4.5 months and it was so difficult but I was given a book called "Happiest Baby on the Block". Seriously this book is a must read for mothers of colicky or fussy babies, it saved our sanity. He will grow out of it and the book gives real solutions for calming him in the meantime that work. Good luck and don't give up yet."

The Implausibility of Vaccine-Based Herd Immunity

The phrase "herd immunity" is tossed a lot these days. I've often seen it used as ammunition against parents who choose not to vaccinate, with something along the lines of, "the only reason your unvaccinated child is so healthy is because those of us who vaccinate are keeping disease rates down". Is this really true? I decided to dig deeper to find out.

Herd immunity requires the assurance that a large percentage of the ‘herd’ (population) is immune and therefore unable to pass on disease. The theory is based on natural immunity, which provides lifelong or long term immunity. [1] Whether vaccination can be substituted for natural immunity when considering herd immunity, is an entirely different question.

Just how effective a vaccine is at providing immunity, is very difficult to gauge. Vaccination provides essentially a half-hearted immune response to infection. It may often provide a strong antibody reaction, but unfortunately provides a very poor innate immune response. [2] Nevertheless, traditionally vaccine effectiveness has primarily been based on antibody levels produced by the body in response to the injected pathogen, and the fact that vaccines illicit a poor innate immune response has largely been ignored.

However, recent research has thrown the traditional theory that antibodies are required for immunity into disarray. It is now known that antibody levels cannot accurately predict immunity. A person can have high levels of antibodies but still become infected, and conversely a person can have low levels of antibodies but not become infected. In fact, in 2012 Moseman et al revealed that antibodies were not even required to gain immunity and that antibodies elicited by vaccines could not by themselves provide adequate immunity. [3]

Pollard et al (2009) noted that children vaccinated with the Hib conjugate vaccine still suffered from Hib disease despite the presence of B-cell immunological memory:
"These children mount a memory immune response to infection but still suffer from Hib disease, which supports our view that the presence of immunological memory does not guarantee protection. These observations strongly suggest that B-cell memory (the kind of immune memory induced via vaccination) might not be as important as longlasting antibodies (T-cell memory cells induced via natural infection) for long-term protection against a rapidly invasive pathogen." [3a]

The immune system as a whole needs to work together, as it does in response to natural infection; something vaccines have to date been unable to achieve.

Despite this, vaccine manufacturers continue to use inadequate antibody testing to rate their products effectiveness. As inadequate and variable as antibody-based immunity conferred by vaccines is, it is further subject to rapid decline soon after vaccine administration, in some cases even after numerous boosters. In 2012 Klein et al studied the waning effect of the whooping cough (pertussis) vaccine and discovered: “The risk of pertussis increased by 42% each year after the fifth DTaP dose.” [4] In stark contrast, in 2009 Wearing et al determined that , on average, whooping cough immunity lasts at least 30 years and perhaps as long as 70 years after natural infection. [5]

It’s no surprise then that vaccines are often demonstrated to be ineffective in real world situations. For example numerous outbreaks of measles, mumps, whooping cough, chicken pox, influenza, and polio have been documented in highly vaccination populations. [6-23, 24-27, 28-35, 36-40, 41-62, 63-64]

In 2009 researchers Witt et al. examined whooping cough incidence in California, and concluded:
"Our data suggests that the current schedule of acellular pertussis vaccine doses is insufficient to prevent outbreaks of pertussis." [65a]

Likewise, in 2013 researchers Sala-Farré et al. studied whooping cough incidence in Vallès and concluded:
"Despite high levels of vaccination coverage, pertussis circulation cannot be controlled at all. The results question the efficacy of the present immunization programmes." [65b]

In addition, the Centers for Disease Control has admitted that unvaccinated people are NOT the cause of recent whooping cough incidence:
"Even though children who haven't received DTaP vaccines are at least 8 times more likely to get pertussis than children who received all 5 recommended doses of DTaP, they are not the driving force behind the large scale outbreaks or epidemics...We often see people blaming pertussis outbreaks on people coming to the US from other counties. This is not the case. Pertussis was never eliminated from the US like measles or polio, so there's always the chance for it to get into a community. Plus, every country vaccinates against pertussis." [65c]

Dr. Anne Schuchat, the director of the CDC’s National Center for Immunization and Respiratory Diseases further explains the recent increase in whooping cough incidence:
“Better diagnosis and reporting of whooping cough may be contributing to the increased numbers, along with the fact that the disease tends to peak and wane in cycles. It does not appear that anti-vaccination sentiment among parents has contributed…” [65d]

While lack of effectiveness constitutes one major problem with vaccination, an even worse complication actually implicates vaccination as a cause of disease epidemics. The current acellular whooping cough (pertussis) vaccine was shown by researchers Warfel et al. to create the illusion of immunity by exhibiting no symptoms in the vaccine recipient, when in fact the recipient was infected and spreading the infection to those around them. [65] Even though vaccine recipients had adequate levels of antibodies to be considered ‘immune’ by vaccine standards, it did not stop the infection persisting in the host or spreading it to others. [65] The researchers concluded:
"The observation that acellular pertussis, which induces an immune response mismatched to that induced by natural infection, fails to prevent colonization or transmission provides a plausible explanation for the resurgence of pertussis and suggests that optimal control of pertussis will require the development of improved vaccines." [65]
The risks associated with the acellular whooping cough vaccine, which has been in use since 1991 [68], have been known as early as 2000. [69] Yet no recall of the vaccine was made, and the cause of reported whooping cough cases continued to be blamed on unvaccinated children. Why this problem wasn’t caught during preliminary testing before licensure of the vaccine is also cause for concern.

Other vaccines have also proven to be problematic. The chicken pox (varicella) and rotavirus vaccines have been documented numerous times causing infection in vaccine recipients and spreading the infection to others. The chicken pox vaccine has also been documented multiple times causing herpes zoster, a related virus with 3 times the morbidity and 5 times the mortality of varicella, in vaccine recipients. [69-93, 94-100]

The measles vaccine may also suffer from a similar problem to the chicken pox and rotavirus vaccines. Researchers Valsamakis et al (1999) studied how the vaccine-based measles virus changed over time when allowed to replicate for an extended period of time in human tissue. They discovered that it grew in strength, evolving back to a strength similar to that of the wild-type measles virus from which it was derived. The researchers warned that individuals with immune deficiency may suffer adverse outcomes if vaccinated, as they may be unable to clear the original, weakened, vaccine-based measles virus, allowing the virus to replicate for an extended period of time and grow to full strength. [101]

Rota et al (1995) found that the measles virus was shed in 14 of the 16 measles vaccine recipients tested:
"Measles virus RNA was detected in 10 of 12 children during the 2-week sampling period. In some cases, measles virus RNA was detected as early as 1 day or as late as 14 days after vaccination. Measles virus RNA was also detected in the urine samples from all four of the young adults between 1 and 13 days after vaccination." [103]

While viral shedding of the live measles vaccine is one concern, another is the risk of infection and subsequent shedding after a vaccinated person has been exposed to a wild measles virus (or a vaccine measles virus that has mutated back to full strength).

Damien et al (1998) found that people who are traditionally considered immune to measles (have produced sufficient amounts of antibodies) can still harbour the measles virus without showing outward symptoms and theoretically spread it to others. This phenomenon is known as an asymptomatic secondary immune response. It applies to both those who have acquired immunity through natural infection or through vaccination, however those who are vaccinated are 5-8 times more susceptible to this response. [102]

After an investigation of a measles outbreak in a highly vaccination school population, Matson et al (1993) found that even after revaccination of school children who did not develop antibodies to their initial measles vaccination, susceptibility to measles infection still remained high (albeit without the appearance of a rash):
"Revaccination appeared to reduce the portion of all students with neutralization titers predicting susceptibility to measles illness with rash from 7.9% to 3.0% and left the portion predicted to be susceptible to illness without rash unchanged (45%)." [104]

Helfand et al (1998) also examined the effects of a measles outbreak in a highly vaccinated school population and concluded:
"Mild or asymptomatic measles infections are probably very common among measles-immune persons exposed to measles cases and may be the most common manifestation of measles during outbreaks in highly immune populations." [105]

Stittelaar et al (2002) get straight to the point in their study, "Vaccination against measles: a neverending story", stating:
"...the current vaccine protects against measles but not necessarily against MV infection."[105a]

Hudgens, et al (2004) also reiterate the point in their study, "Endpoints in vaccine trials":
"...vaccines for rubella, mumps, measles, and polio have been shown to prevent disease, but not infection."[105b]

These results are not surprising given that vaccines that are injected, such as the MMR, do not stimulate mucosal immunity.[2] However the mucosa is precisely where the majority of infections reside.[106] So while vaccine recipients are usually protected from severe symptoms such as a rash or fever, many are still susceptible to infection, and will pass the infection on to those around them.[102]

This completely shatters any illusion that at least these particular vaccines can provide herd immunity. It implicates the current whooping cough, chicken pox, rotavirus, and possibly the mesasles vaccines as a cause of disease resurgence, and implicates the whooping cough vaccine as a cause of lowered immunity. The fact that antibodies alone have been shown unable to confer adequate immunity to pathogens calls into question the use of vaccination as a whole, as vaccine based immunity is primarily based on antibody production.

For these reasons, it is my opinion, that vaccination cannot in good conscience be used in the context of herd immunity. Until safer and more effective vaccines become available it seems a gamble to assume that vaccine recipients are truly immune.
