Most often associated with super-bugs and sickness, bacteria’s bad-boy image hides their friendlier faces. For centuries “good” bacteria have been used as a starter cultures for yoghurts and fermented dairy drinks. Today beneficial bacteria are in high consumer demand, in particular probiotics.

  • Probiotics are live microorganisms - such as bacteria, yeasts and fungi - which in adequate amounts may have health benefits. Studies have shown they can improve digestion, help protect against disease and enhance immune function.
  • Strains of lactobacillus and bifidobacterium bacteria are the most commonly used probiotics as they can survive the passage to the gut.
  • Probiotics are most widely available as dietary supplements in tablet, capsule and powder forms or as a component in yoghurts and fermented dairy drinks.
  • Prebiotics are non-digestible food ingredients that can increase the activity of select “good” bacteria. Prebiotics naturally occur in bananas, asparagus, leeks, onions, garlic, chicory and wholegrains like wheat, rye, barley and oats. Savvy marketers are spruiking their benefit in foods from breads to infant formulas (see Bugs for Babies).

Bug benefits

In a healthy gut, there is a balance between beneficial and pathogenic or “bad” bacteria. Climate, ageing, food, stress, illness or infection and medications can disrupt this balance leading to an excess of “bad” bacteria leading to bloating, gas and constipation. While individual studies and anecdotal evidence suggest a wide range of uses, well-studied and accepted uses for probiotics are much fewer.

Probiotics may help prevent traveller’s diarrhoea and diarrhoea caused by antibiotics, and are used in the treatment of acute infectious diarrhoea. The lactobacillus rhamnosus GG and saccharomyces boulardii strains have been shown to be most effective for these conditions, but there are no formal clinical guidelines for probiotic use. Accredited practising dietitian Milena Katz says that a person’s gut bacteria are very individual – like a finger print - so there is no blanket advice. Katz says it’s a case of trial and error and advises patients with gut problems to try high strength probiotic capsules over six weeks to see if symptoms improve.

For healthy people, probiotics aren’t necessary, but Katz says eating probiotic foods like yoghurt aren’t going to hurt and are generally well tolerated. Probiotics are not advised for people with severe illnesses or who are immunocompromised.

Popular opinion

When CHOICE asked people about probiotic use, positive messages abounded: “Yakult, every day. No ill effects. Actually think they are part of me beating Crohns”. Another said he used kefir (an eastern European probiotic drink) and “never had any ill effects, just the opposite in fact!”. One fan of Inner Health Plus wrote: “It helps my partner who suffers with MS and often has problems with candida (a yeast) overload in his throat and a bloated tum”, while another commented: “I also have an irritable bowel and a bloated tummy at the best of times... It helps but has not solved the problem completely”.

Strains of bifidobacteria and lactobacilli – along with other lactic acid bacteria - are found naturally in breast milk and thought to contribute to normal gut development and function. In newborns, bifidobacteria make up 95% of the gut’s microbial population but this decreases to 25% in adults.

Manufacturers such as Nutricia, which makes Aptamil (formerly Karicare) infant and toddler formulas, are adding prebiotics to their products. Listed as galacto-oligosaccharides (GOS) and long chain polyfructose, Nutricia says these are “similar in form and function to the prebiotics found in breast milk” and “encourage the good bacteria in the digestive system to flourish, reducing the amount of harmful bacteria” and “assist in digestion and promote softer stools”.

A recent report by the American Academy of Pediatrics says there may be some long-term benefit of prebiotics [such as oligosaccharides] for the prevention of atopic eczema and common infections in healthy infants, and while adding probiotics to infant formulas wasn't shown to be harmful to healthy infants, more evidence is needed to support routine use.

8 MONTHS AGO | Hi,
good quality stainless steel is non-magnetic, so testing it with a magnet is useless.
St/St cookware suitable for induction cooking has steel embedded in its base, the same as some copper items.
I have used induction cooking for years: it is the best!
Regards, Ernst

8 MONTHS AGO | We've had trouble with finding frypans of a big enough size. With a Neff induction cooktop a large percentage of the 'hot plate' needs to be covered otherwise the whole area does not function. Even my largest frypan does not cover enough of the biggest hot plate so only activates the smaller inner circle. This means that food near the edge of the frypan does not cook. Has anyone bought a good large frypan?

8 MONTHS AGO | I have had trouble with fry pans/ skillets. If I use a high heat the base will warp so it bows upwards, then they are useless as the heat does not distribute evenly. Both times they were expensive and supposed to be good for induction. The sales team say they should only be used on medium heat, my view is its a frypan so it should cope with high temperatures.

9 MONTHS AGO | Hello,
My question is: as there are many brands of induction cooktops and prices vary greatly.
How would I know the quality of the brand? Is the price the only indication of a good unit or are there other indications.
Looking forward to your response
Regards W van der Kooi
