Fasting diet could reverse diabetes symptoms by regenerating pancreas
A type of fasting diet has been found to help regenerate the pancreas – which helps control blood sugar levels – and reverse symptoms of diabetes in animal experiments, US researchers say.
According to the study by researchers at the University of Southern California, the findings were “potentially very exciting” as they could become a new treatment for the disease. The study also says the diet reboots the body, although people are not encouraged to try it without medical advice.
In the experiments, mice were put on a modified form of the “fasting-mimicking diet”.It is like the human form of the diet when people spend five days on a low-calorie, low-protein, low-carbohydrate but high unsaturated-fat diet.
It resembles a vegan diet with nuts and soups, but with around 800 to 1,100 calories a day.Then they have 25 days eating what they want – so overall it mimics periods of feast and famine.
Previous research has suggested it can slow the pace of ageing.But animal experiments showed the diet regenerated a special type of cell in the pancreas called a beta cell.These are the cells that detect sugar in the blood and release the hormone insulin if it gets too high.
Dr. Valter Longo, from the University of Southern California, said: “Our conclusion is that by pushing the mice into an extreme state and then bringing them back – by starving them and then feeding them again – the cells in the pancreas are triggered to use some kind of developmental reprogramming that rebuilds the part of the organ that’s no longer functioning.”
There were benefits in both type 1 and type 2 diabetes in the mouse experiments.
Type 1 is caused by the immune system destroying beta cells and type 2 is largely caused by lifestyle and the body no longer responding to insulin.
Further tests on tissue samples from people with type 1 diabetes produced similar effects.
Longo said that the findings have the potential to be medically important as it showed, at least in mouse models, that diet can be used to reverse the symptoms of diabetes. “Scientifically, the findings are perhaps even more important because we’ve shown that you can use diet to reprogram cells without having to make any genetic alterations,”he added.
