Resistant starch is a prebiotic that nourishes your gut bacteria in your large bowel (colon) which improves its function through the production of short chain fatty acids. One of these, called butyrate, is food for the cells in your colon wall. When your gut bacteria produce butyrate, your colon wall becomes stronger and less permeable. Six out of ten Australians don’t eat enough fibre, and even more don’t get the right combination of fibres. The recommended intake of resistant starch is around 20 grams a day, which is almost four times greater than a typical western diet provides. Twenty grams is equivalent to eating three cups of cooked lentils.- CSIRO. “We have been trying to find out why Australians aren’t showing a reduction in bowel cancer rates and we think the answer is that we don’t eat enough resistant starch, which is one of the major components of dietary fibre,” - Dr David Topping, CSIRO. The relationships between starch, RS and NSPs and cancer incidence remained statistically significant after adjusting for fat and protein intakes. The strong inverse associations found here suggest a potentially important role for starch in protection against colorectal cancer and correspond with the hypothesis that fermentation in the colon is the mechanism for preventing colorectal cancer. - British Journal of Cancer Current knowledge suggests that resistant starch in the diet may assist in the prevention and management of conditions associated with the Metabolic Syndrome via its potential effects on delaying the delivery of glucose as fuel with subsequent fat utilisation and appetite control benefits. ro.uow.edu.au/cgi/viewcontent.cgi?article=1045&context=hbspapers Resistant Starch and Butyrate: Unlike other forms of starch, it’s not broken down into glucose by your digestive system. Instead, it behaves like fibre, passing through your stomach and small intestine undigested. When it reaches your large intestine, or colon, it feeds the beneficial bacteria that live there. When these gut bacteria metabolise the resistant starch, they produce short chain fatty acids. One of these, called butyrate, is food for the cells in your colon wall. When your gut bacteria produce butyrate, your colon wall becomes stronger and less permeable. This helps prevent toxins produced by bad bacteria from leaking through the wall of your colon and into your bloodstream. Some research suggests that butyrate increases the number of regulatory T-cells in the intestine, and so prevents immune responses from getting out of control. In fact, scientists are now experimenting with the use of butyrate to treat inflammatory bowel disease. People with IBD seem to have low levels of intestinal butyrate. Studies show that resistant starch has many benefits. It increases sensitivity to insulin and lowers fasting blood sugar. It lowers cholesterol levels. It encourages bowel regularity and can indirectly promote weight loss by making you feel full quickly. It may help prevent colorectal cancer. - The easiest way to add resistant starch to your diet: Bobs Red Mill Potato Starch. Available now at OptimOZ - bit.ly/1Bdkyoo
