Kimchi

[Sandra]

Eating up to three servings of kimchi a day could reduce the amount of fat around your middle - potentially reducing the risk of diabetes, a major study has suggested.

Kimchi, a traditional Korean dish made of fermented vegetables such as cabbage, has long been linked to health benefits such as regulating digestion and boosting memory.

Now, a study of more than 100,000 people by researchers from the Chung Ang University in South Korea has found that men who eat three portions of the dish per day are less likely to be overweight and have less belly fat - the type thought to be the riskiest for type  2 diabetes.

I did try this a while ago and its not the nicest thing I have ever in my mouth but maybe I should give it another go 

I do drink Kombucha (Flavored cold tea drink with fermentation) so why not.
