When most people here the word ‘carbs’ they immediately associate the term with things like weight gain, ‘bad’, unhealthy, should be avoided.
But the more we research gut health, the more we’re beginning to realise just how detrimental cutting starches out of our diets can be.
I recently went to the premier of The Gut Movie which confirmed a lot of which I’d been recently been researching. The film follows the journey of Kale Brock as he travels from Australia to Namibia to live with an ancient hunter-gatherer people living traditionally from the land.
During the documentary, Brock not only monitors his own microbiome and how it changes after his time spent living with the tribe, but he also speaks to numerous researchers and even takes microbiome samples of The San.
Some of the biggest take aways for me included:
Starches are long chains of glucose that are found in grains, potatoes and other various carbohydrates.
They are composed of two types of polysaccharides:
Resistant starch is the best friend of friendly gut bacteria. Resistant starch, unlike other starches has the ability to make it through the stomach and small intestine before reaching the colon where it feeds the friendly bacteria in the gut (reference). When the bacteria digest resistant starches, they form short-chain fatty acids, the most significant of which is called butyrate. This is known as the anti-inflammatory fat, which not only helps your gut work right, but can be important for gut-related diseases.
Health benefits of adequate intake of resistant starches can include: (reference)
There are 4 different types of Resistant Starch:
Although there is no formal recommendation for the intake of resistant starch, many studies show health benefits of 15-30 grams per day.
Some foods high in resistant starch include:
100 grams of cooked rolled (not instant) oats can contain around 3.6 grams of resistant starch, as well as being high in antioxidants.
As cooking oats has been shown to damage much of the resistant starch, by allowing your cooked oats to cool for several hours you can repair much of this loss and increase the levels of resistant starch.
Beans and legumes provide large amounts of fiber and resistant starch.
Depending on the type of legume, they contain around 1-4 grams of resistant starch per 100 grams after cooking.
When using dried beans and legumes, it’s recommended they be be soaked and fully heated to remove lectins and anti-nutrients.
Raw potato starch contains about 8 grams of resistant starch per tablespoon and almost no usable carbohydrate.
It can be used as a thickener or added to smoothies, overnight oats or yogurt.
It’s important not to heat potato starch, so if you would like to add it to a dish, prepare the meal and then add the potato starch once it has cooled.
If you’re not use to consuming such quantities of resistant starch, it is recommended you start slowly and work your way up, as too much too soon can cause gasiness and bloating.
Cooking potatoes and then allowing them to cool significantly increases their resistant starch content.
It’s important not to reheat the potatoes, so opt to have them as part of a homemade potato salad or side dish.
As bananas ripen, the resistant start transforms into simple sugars like fructose, glucose and sucrose, which is why consuming them whilst still green is important if you want to maximize your resistant starch intake.
You can treat Hi-Maize flour as you would potato starch by adding it to yogurt or oatmeal.
Cooking and cooling other starches will increase their resistant starch content, meaning this method can be applied to many carbohydrate which foods including pasta.

So there you have it. If like me you’re interested in improving your gut health, immune system, blood sugar levels, digestive system, mood and weight, it’s worth giving resistant starches a go in your diet.Tags: carbohydrates, carbs, digestive health, Fat Loss, featured, gut health, healthy living, Lifestyle, Mental Health, nutritional advice, personal trainer, Perth Wellness, the gut movie, Weight Loss
