Probiotics seem to be something that everyone is talking about these days, but what exactly are they? What do they do? Where do they come from? How do I know if I need one?
'Probiotic' literally means 'for life'. More often are defined as being "viable microorganisms that have a beneficial effect in the prevention and treatment of specific pathologic conditions when they are ingested". Basically they are the good bacteria that should be found in your gut. Did you know that approximately 85% of your immune system is found in the gut? This is because it is the job of these good bacteria to be the gatekeepers to our body. They are our first defence against foreign bodies, preventing colonization by viral and bacterial pathogens.
Wondering where you got your good bacteria from in the first place? Your mum! During a vaginal delivery the baby is covered in secretions which contain it's mothers bacteria. The mother passes her gut flora on to her baby and this in turn colonizes their gut. From that day forward we are constantly changing our gut flora depending on what we ingest. We are exposed to coughs, colds, travel, different foods, medications and all of these impact our gut ratio between good and bad bacteria.
Sat there thinking well my granny hasn't taken a probiotic and she never gets ill at 96! The truth is that she has probably had her fair share of 'probiotics' but they just didn't call them that then. Traditionally fermented foods like sauerkraut, kefir, kombucha, raw yoghurt and even beer were all sources of good bacteria. In the days before fridges and supermarkets, fermentation was a way of preserving produce to survive long winters.
These days everything goes in the fridge, crops are sprayed with pesticides which just like the antibiotics you get from the doctors are not selective about whether the bacteria they are killing is good or bad. Most supermarket products have also been pasteurised to extend shelf life and prevent outbreaks of harmful bacteria. This means that the good bacteria in traditionally fermented foods is killed along with any bad that may have been present.
The good news is that there is now a move back towards traditional probiotics with kefir, kombucha, and sauerkraut gaining in popularity. Thinking about stocking up on those yoghurt drinks from the supermarket? Think again! Did you know that many of them have more sugar per 100g than fizzy pop? One of the easiest ways to up your good bacteria is to take a probiotic supplement many of which also contain prebiotics (food not absorbed by the host that supports the growth of good bacteria).
So do you need a probiotic? The reality is that most of us should take a probiotic supplement even just in the short term. Why? The vast majority of us have at some point done at least one of the following all of which negatively effect your gut flora: taken an antibiotic; suffered from colds and viruses; have IBS or IBD; taken the contraceptive pill; taken steroids; travelled abroad; suffer from or have a family history of auto immune conditions e.g. under-active thyroid, diabetes, lupus, psoriasis, etc; or allergenic conditions e.g. food allergies and excema.
There is a wealth of research out there which clearly demonstrates the huge role that probiotics have in supporting our immune system and preventing disease. A recent study examining the role of probiotics in the reduction of diabetes states that probiotics contribute to a reduction in inflammatory response and oxidative stress. This leads to increased insulin sensitivity and a reduction in the autoimmune response.
Allergenic diseases have increased over the last 40 years in industrialized nations but NOT in the developing world. Put simply we are just too clean, our homes and farms are sprayed to within an inch of their lives, we eat processed foods and we aren't exposed to the diseases we once were. All of this impacts on our gut flora and prevents the normal responses to allergens from developing properly leading to an increase in disease. Children with food allergies have been found to have an imbalance between good bacteria and potentially harmful ones. The same has been observed in a study of children with atopic eczema.
So which one should I take? Well the answer is it really depends on you and what your individual needs are. A good starting point would be something like Bio-Kult or Optibac for everyday. However, there are a variety of ranges designed specifically for different needs: travel abroad, when you're taking antibiotics, pregnancy, breastfed babies, bottlefed babies, managing cholesterol levels, one for women for targeting the intimate flora, the list goes on.

Do you spend summer a snivelling mess constantly searching for a hankie? Hay fever is a sure fire sign for many that summer is on it's way, that first tell tale sneeze in late spring as everything starts to bloom. Yup it's tissue time again. If like me you can't leave the house without a packet of tissues at this time of year our salvation may have been found....Probiotics!
Researchers at Vanderbilt University School of Medicine have reviewed 23 studies analysing the most up to date data on the use of probiotics in the treatment of hay fever. They concluded that in the majority of studies patients symptoms improved significantly by using probiotic compared with those who don't.
So there you have it, teeny tiny microorganisms are the answer we've been looking for! There are a number of different options available and we usually advise on particular strains of bacteria based on other health challenges.
Other foods that can worsen symptoms are caffeine and alcohol and foods that contain histamine e.g., red wine, cheese, chocolate, and tomatoes. Wheat based foods can add to the inflammation for some and dairy products can increase mucus production as can sugar and excess starchy foods. Then there are those foods which are individual to you and these can be tested for via IgG Food Intolerance testing.
Foods that support hayfever sufferers are those that reduce inflammation. Oily fish which increases our omega 3 fatty acids is anti-inflammatory. We can also supplement with this especially over the season. Incorporate ginger, rosemary and thyme into your cooking. Make ginger teas from fresh ginger and nettle. These foods will help counteract a runny nose and itchiness.
Raw honey bought from local farms and bee keepers has been spoken about for a while and many have found taking a spoonful a day to be extremely helpful during pollen season.
Supplementing vitamin C is helpful as it’s a natural anti-histamine. Most important is ensuring a rainbow diet with lots of flavonoids and a good range of nutrients.
Another natural anti-histamine is quercetin found in foods such as red onion, peppers and citrus. This can be supplemented but if you are on medication, please contact a Nutritional therapist as it does have some drug nutrient interactions.
Tumeric is another favourite of ours for hay fever support as research published in the journal Molecular Nutrition and food research 2008 demonstrated that turmeric prevented mast cells from releasing histamine.
Oil of oregano has been shown in animal studies to prevent histamine release due to its component rosemarinic acid.
Two of our favourite products for hay fever prevention combine the above to take best advantage of the latest science. These are quercetin plus and Epigenar Curcumin oregano quercetin complex.
Whichever you go for, we hope that you will soon be able to leave your hankies at home!
