Study: An apple carries about 100 million bacteria – which is good



GRAZ, Austria – What is the old adage? "100 million bacteria per day keep the doctor away?" A new study shows that a typical 240g apple contains about 100 million bacteria, mainly in seeds and skin. This may sound a bit disgusting at first, but researchers say the more bacteria there are, the better gut health.

Graz University of Technology researchers indicated that organic apples contain even more Bacterial properties are more diverse than traditional apples, making them possibly healthier, tastier and more environmentally friendly.

"The bacteria, fungi and viruses in our food temporarily colonize our intestines," explains senior author Professor Gabriele Berg in a press release. "Cooking kills most of it, which is why raw fruits and vegetables are a particularly important source of intestinal microbes."

Berg and her team went in search of the best source of beneficial intestinal microbes and decided to target one The most popular fruit in the world belongs to the apple.

"In 201

8, 83 million apples were grown and production continues to increase," says Berg. "While recent studies have mapped their fungal levels, less is known about the bacteria in apples." Researchers analyzed and compared bacterial levels in store-bought apples and organic apples. Each apple was piece by piece decomposed and analyzed, d. H. Stem, peel, seeds, etc.

Both types of apple generally had the same amount of bacteria – 100 million, mainly in the center of the apple. For example, if you remove the nucleus, the bacteria count of a typical apple drops to 10 million.

The organic and processed apples, however, differed with respect to the bacterial species . Organic apples had a much greater variety of bacterial communities than the regular samples. This is remarkable in that, for gut health, diversity is even more important than quantity.

"Freshly harvested, organically farmed apples have a much more diverse, consistent and clearer bacterial community than conventional ones," explains Berg. "This strain and its balance are expected to limit the overgrowth of a species, and previous studies have shown a negative correlation between the frequency of human pathogens and the microbiological diversity of fresh produce."

It has also been shown that organic apples contain only lactobacilli. a pretty well-known probiotic. In contrast, conventional apples contained bacteria known to harbor pathogens. The research team even says that organic apples contain much more of a certain bacterium, Methylobacterium, which is known to improve the taste quality of fruits. Pesticide-bred apples.

Berg and her team say that microbiome information on fruits and vegetables may one day be as readily available as more traditional nutritional information.

The study was published in the journal Microbiology.
