Resistant starch and a healthy gut

Happy Monday morning everyone!

There's an interesting commentary in today's Medical Journal of Australia on resistant starch - we should be eating more of it ! 

So what is resistant starch? 

Resistant starch is a type of dietary fibre that is fermented in the large bowel and feeds the gut microbiome- the bacteria in your bowel that do so much good. Despite the messages to eat more fibre, and people are doing that, most people are increasing their fibre with processed foods like cereals, which don't necessarily contain resistant starch. More fibre yes, but all the great health benefits, no.  There is evidence that a healthy gut microbiome plays a role in preventing diabetes, obesity and some cancers, so its worth taking a moment to understand how to keep it healthy.

So where do you find resistant starch? 

It can be found in some starchy fruits and vegetables (eg bananas and sweet potatoes), in legumes (have I told you how awesome beans, chick peas and lentils are lately?) and interestingly,  in some cooked and cooled starchy foods. Cooking and cooling starchy foods like  rice, pasta and potatoes, and eating them cold, lowers the GI and increases the amount of resistant starch. Add some healthy fats and lemon juice and you lower the GI further - so in great news for the southern hemisphere, summer is coming and its time for potato salad, pasta salad and rice salad OH YEAH!
