Probiotics – sources, effectiveness and safety

Probiotics in foods
on Fri 29 May

 

You might be surprised to know that a normal healthy bowel contains about 100 trillion micro-organisms representing more than 500 different species

 

These keep pathogens (harmful microorganisms) in check, helps us digest food, fight harmful bacteria, and regulate the immune system.

 

However,  the gut can become unbalanced and this can lead to diarrhoea and other health problems.

 

Probiotics (often called good bacteria) can help restore the balance however; we are still learning how probiotics may actively promote health by treating certain conditions.

 

Where do I get probiotics from?

You don’t necessarily need to take supplements. Probiotic-rich foods include

  • Buttermilk
  • Cottage Cheese
  • Fermented Pickles
  • Fermented Saurkraut
  • Kefir (fermented dairy drink)
  • Kimchi (fermented cabbage)
  • Kombucha (fermented tea)
  • Miso Soup
  • Sourdough Bread
  • Tempeh ( a plant based protein made from fermented soy beans)
  • Yoghurt

 

The most common species of bacteria in probiotic supplements is Lactobacillus or Bifidobacterium.  These are freeze dried (but living) and become fully active in the digestive system when they warm up.

 

Always read the label - several probiotic strains are fragile (needing protection from heat, light or oxygen) so need to be suitably in order that you will get the full benefit.

 

Are probiotics effective?

Researchers are currently unsure how effective probiotic supplements are for treating particular conditions although there are claims that they are beneficial in the prevention or treatment of digestive health challenges such as:

 

  • Crohns Disease
  • Diarrhoea
  • Pylori (the cause of ulcers)
  • Infection of the digestive tract caused by Clostridium difficile
  • Irritable bowel syndrome
  • Ulcerative colitis

 

Probiotics may also assist in terms maintaining urogenital health.  Lactobacilli in the vagina make this finely balanced ecosystem too acidic for harmful micro-organisms to survive but use of antibiotics, spermicide or birth control pills can distort the balance of the microflora.

 

For this reason some women may look at using probiotics to help with common problems such as bacterial vaginosis, yeast infection, and UTI’s (urinary tract infection)

 

It is not uncommon for women to insert yoghurt into the vagina to treat thrush, but you might be surprised to know that there is limited support for this by medical science

 

Probiotics and Coronavirus

Research in February 2020  and May 2019 has led to scientists in the UK asking our Health Secretary to look at the “emerging role of gastro intestinal health in relation to Covid-19”

However this is still to be ratified.

 

Are probiotics safe overall?

As these are health supplements rather than medication these are not regulated. However, since they are present in a healthy digestive system they are generally considered safe. The possible exception to this is when being taken by someone with a weakened immune system.

 

Some people experience loose stools in the first few days of taking probiotics however this soon goes away and you may be able to avoid this by taking probiotics at the end of a meal.
