Eating a serving of button mushrooms a day could prevent type 2 diabetes, new research suggests.
Feeding mice a daily portion of white button mushrooms boosts their levels of a gut bacteria that is involved in the production of glucose, a study found. The serving is the equivalent of 85 grams for humans.
According to the researchers, mushrooms act as a prebiotic, which are indigestible food ingredients that ‘fertilise’ the growth of bugs in the digestive tract.
Study author Professor Margherita Cantorna, from Pennsylvania State University, said: ‘Managing glucose better has implications for diabetes, as well as other metabolic diseases.’
Type 1 diabetes occurs when glucose levels rise due to a lack of the hormone insulin, which controls glucose’s movement in and out of cells. In type 2 diabetes, insulin levels are insufficient or the body does not respond to the hormone.
Around 3.2 million people in the UK are diagnosed with diabetes, of which 10 per cent have type 1. Type 1 diabetes affects approximately 1.25 million people living in the US, while 9.4 per cent of the population have type 2.

How the research was carried out
The researchers analysed two types of lean mice. The first had gut bacteria, while the others did not and were ‘germ free’.
Professor Cantorna explained: ‘You can compare the mice with the microbiota with the germ-free mice to get an idea of the contributions of the microbiota.’
All of the rodents were fed a daily serving of mushrooms, which is the equivalent of around a 85g portion for humans. It is unclear how long the animals were fed the edible fungi for.
‘Any change you make to the diet, changes the microbiota’
Results, published in the Journal of Functional Foods, suggest eating mushrooms increases levels of the bacteria Prevotella in mice.
Prevotella produces the acids propionate and succinate, which play a role in the expression of genes that manage glucose production.
The researchers hope to repeat the experiment in obese mice, as well as humans.
Mushrooms aside, Professor Cantorna added: ‘It’s pretty clear that almost any change you make to the diet, changes the microbiota.’
Scientists create an insulin pill with ‘remarkable’ results
This comes after research released last June suggested scientists have created an insulin pill that could signal the end of injections for diabetics.
Unlike previous failed attempts to make oral diabetes medications, the pill survives the acidic environment of the stomach to release insulin into the bloodstream, according to the scientists.
After rats were given the unnamed pill, their blood-glucose levels fell by 38 per cent in two hours and 45 per cent after 10 hours, compared to a 49 per cent decrease in 60 minutes among those given insulin injections, a study found.
The researchers believe the drug may overcome the pain and needle phobias some diabetics experience.
Dr Mark Prausnitz, from the Georgia Institute of Technology, who was not involved in the study, said: ‘This study shows remarkable results where insulin given by mouth works about as well as a conventional injection’.
It is unclear when the drug may be available and if it would benefit type 1 or 2 diabetes patients.
