Are Antibiotics linked to Peanut Allergies?

Screen Shot 2016-09-01 at 2.08.31 PMOver-exposure to Antibiotics at a Young Age Increases the Risk of Developing Food Allergies

Are antibiotics linked to food allergies? Absolutely!

An animal (young mice) study released in August 2014 (published in the Proceedings of the National Academy of Sciences) indicated that young children over- exposed to antibiotics are at greater risk of developing food allergies such as peanut allergies later in life.

The study performed at the New York University Medical Centre fed antibiotics to young mice.

What they discovered was that when these mice were exposed to known allergens like peanuts, this group were more likely to develop a peanut sensitivity than the control group.


Researchers were subsequently able to identify two key areas of interest:

1. They were able to identify a naturally occurring bacteria in the human gut that prevents people from developing food allergies.

However this beneficial gut bacteria diminished with frequent antibiotic use at a young age — making children more susceptible to food allergies later in life.

2. By dosing with Clostridia – a bacteria that occurs naturally in the guts of mammals,  the peanut sensitivity in the young mice disappeared.


 Anaphylaxis Due to Food Allergy is on the Rise

  • The most common triggers are hens egg, cows milk, peanuts and tree nuts.
  • Less common triggers include seafood, sesame, soy, fish and wheat.
  • Peanuts, tree nuts, seeds and seafood are less likely to be outgrown and tend to be lifelong allergies.


In 2014 food allergy occurs in around 1 in 20 children and in about 2 in 100 adults in Australia. Until the 1990s food allergies were quite rare and there’s no definitive explanation for why they’ve now become so common. Around 71,000 boys aged from 2 to 18 have an allergy or intolerance to peanuts, compared to only 39,000 girls. Among the theories for the steep increase in food allergies is the “hygiene hypothesis”.

This theory contends that we’ve become too clean and our gut doesn’t have the normal bacteria. This ties in with overexposure to antibiotics as a young child.  Additionally it is known that the increase in childhood food allergies  has something to do with modern lifestyle.  The rises have occurred very quickly in the last 10 to 20 years and our genes don’t change that quickly.

Hospital admissions for severe allergic reactions (anaphylaxis) have doubled over the last decade in Australia. In Australia, admissions for anaphylaxis due to food allergy in children aged 0 to 4 years are even higher, having increased five fold over the same period.

The Murdoch Childrens Research Institute state that up to one in ten one year olds have a clinically confirmed food allergy. Of particular concern – hospital admissions for anaphylaxis in children under 18 years old in Australia increased up to 350% in the period 1994-2004.

This research indicates that not only are we are overly dependant on antibiotics but that this over prescription is a key factor in developing food allergies in young children that can continue to have ramifications throughout their lifetime. To combat this anti-biotic damage it appears as though dosing with probiotics is a potential direction in reducing the impact of these antibiotic induced food allergies.


Reducing the Impact of Antibiotic Damage

  • Recolonise the bowel using probiotics. Click here for Emeds Best Probiotics. In our gut live a trillion helpful bacteria (known as gut flora) that have evolved in symbiosis with humans. A course of antibiotics alters this symbiosis. Studies reveal some while some of these changes are short term, other changes are irreversible or could take 1-4 years to revert to normal.
  • If you suspect you or a family member suffers from food allergies, Emed offers Food Allergy testing that lets you know – once and for all – what you can eat, and what you can’t. Click here for Emeds Food Allergy Testing.
  • Take Glutamine. When you take a course of antibiotics the intestinal mucosa is injured and little holes can appear – this is called Leaky Gut. Bacteria penetrates the intestinal wall and enters adjacent tissue, and can enter the bloodstream. Glutamine, an amino acid, is essential to repair the gut lining. Anti Inflammatory Mucosal Support provides Glutamine, Aloe Vera and zinc to restore intestinal gut lining.

    It’s all well and good that there’s a growing awareness on the detrimental effects of antibiotics but it’s awfully slow and more needs to be done and FAST. Antibiotics may have benefits in very specific circumstances, but doctors need to stop prescribing them unnecessarily because we’re now beginning to see the horrific impact that these powerful drugs have on the human body, not only for the individual taking them but society as a whole. Chronic digestive disorders including colon cancer have never been higher and these diseases are rising at an alarming rate. Don’t even get me started on antibiotic resistant bacteria which is officially declared as the biggest health threat to humans by the WHO. News media likes to bombard us with news pertaining to the war on street drugs, but where’s the coverage on the prescription drugs and their impact? Why are we not panicking When the World Health Organization themselves (highest health authority in the world) say that antibiotic resistant bacteria, which are CAUSED BY ANTIBIOTIC DRUGS, are a GLOBAL THREAT!?

    I’m sorry to say but the probiotics on the market today are sadly grossly inadequate when it comes to reestablishing the micro flora lost due to antibiotics. Our prime focus needs to be on fecal bacteriotherapy including encapsulating healthy fecal bacteria for oral administration and eventually to make this procedure available to the millions of people who are suffering and desperately need it. In the mean time the focus should be on unpasteurized live fermented whole foods which contain many times more beneficial microorganisms than any current probiotic supplement. In addition to the vitally important beneficial microrganisms, they provide key enzymes, vitamins and minerals which which work together in supporting gastrointestinal health and hence overall well-being.

    How sad that the vast majority of doctors have NO IDEA what the fecal bacteriotherapy/fecal microbiota transplant procedure even is! Why? Because the majority of them refuse to acknowledge the damage that antibiotics are doing to our microbiology and the detrimental effects this has on the whole organism and the environment. It is ironic to say now, in the age of bacteria phobia, but I believe microbiology, specifically gut microbiology is the future of medicine and healthcare. The sooner we realize this the better.

    I’d like to lastly say that I strongly believe antibiotics should NOT be used outside of hospitals and even then under very specific circumstances where the doctor and patient are fully informed of the cost and benefit to the usage of such drugs.
