There has been a lot of research when it comes to digestive health. It has a bigger impact on the body than most people think. Good gut health has many exciting health benefits. Let's take a look at the research.
Resistant starches are a special type of food that have amazing health benefits. They are in foods like bananas, beans, and whole grains. They are "resistant" because they aren't digested but go through our digestive tract to the colon.
In the colon, these starches help feed the good bacteria in our gut. This is good because it keeps our stomach healthy and helps to fight off sickness. Research shows that these starches can protect people from disease and not get sick as often.
But there's more!
Resistant starches are also able to keep our blood sugar steady. This is especially important for people who have diabetes or might get it. Eating these types of foods can also help stop blood sugar from rising too fast.
These starches help us feel full, which can help with losing weight. When we are full, we don't eat as much, so it's easier to stay healthy.
Resistant starches are also good for our hearts. They can lower bad cholesterol, which is important for keeping our hearts healthy.
Finally, these starches help our bodies use insulin better and reduce inflammation. This is helpful for people with certain health conditions. So, eating foods with resistant starches is a great way to be healthy.
Resistant Starch: What Is It?
To understand the benefits of dietary starch, it is important to know how they function in our bodies. Resistant starches are molecules that don't digest in the small intestine. Instead they make their way to the large intestine where gut bacteria ferment them. This fermentation process produces short-chain fatty acids (SCFA). SCFA can improve glycemic control and lead to a reduced risk of colon cancer.
Resistant starch is a lot like soluble, fermentable fiber. They help feed the friendly bacteria in your gut and increase SCFA production. This sets resistant starches apart from regular starches. By "resisting" digestion these starches offer health benefits that regular starches don't.
What Are Resistant Starches and Why Are They Important?
Resistant starches are a type of starch that "resists" digestion. They pass through the small intestine and reach the large intestine intact. They act as prebiotics, feeding the beneficial bacteria in our gut. This promotes digestive health, improves insulin sensitivity, and aids in body weight management.
The Science Behind Carb Resistant Starches
As mentioned earlier, resistant starches don't digest in the small intestine. Once in the large intestine, gut bacteria ferment these starches, producing SCFA. These fatty acids, such as butyrate, acetate, and propionate, play a crucial role in our health.
The fermentation of resistant starches has many health benefits including improved glycemic control. When we eat resistant starches, they can help regulate blood sugar levels. They improve carbohydrate and lipid metabolism as well. This is good news for people with insulin resistance or type 2 diabetes. Resistant starches promote healthy insulin levels and reduce the risk of insulin resistance. 1
Resistant starches can also aid in weight loss. They help us feel full, which can help control appetite and reduce calorie intake. By stabilizing blood sugar levels, resistant starches also help prevent blood sugar spikes. Blood sugar spikes can often lead to cravings and overeating.
Types of Resistant Starches
There are four types of resistant starches, each with special features and benefits. Understanding these types of starch can help people make the right food choices.
- Type 1 resistant starch is present in grains, seeds, and legumes. This type is resistant because of the physical structure of granules. This makes it more resistant to digestion.
- Type 2 resistant starch is in raw potatoes and green bananas. It is resistant due to its high amylose content, which is a type of complex carbohydrate.
- Type 3 resistant starch forms when we cook starchy foods and then cool them. Some examples are potatoes, rice, and bread. This process alters the starch molecules and makes them resistant to digestion.
- Type 4 resistant starch is changed by a chemical process and is often used in by food manufacturers. This type of resistant starch does not occur naturally. It is usually added to foods as a dietary fiber source.
Health Benefits of Resistant Starches
Now that we understand what resistant starches are, let's explore their health benefits. Resistant starches have many benefits, from improving insulin regulation to supporting gut health.
Role in Insulin Regulation
Resistant starches are good for people with insulin resistance or type 2 diabetes. Resistant starches promote healthy insulin levels and help regulate blood sugar levels. Especially after meals high in carbohydrates such as white rice. 2 They prevent blood sugar spikes, which can lead to the development of type 2 diabetes.
Do Resistant Carbohydrates Improve Gut Health?
Resistant starches improve gut health by acting as prebiotics. A prebiotic provides nourishment to the beneficial bacteria in the gut. This promotes a healthy balance of gut flora and reduces digestive problems. 3
A healthy gut microbiome is essential for digestive health and well-being. Increased intake of resistant starch contributes to the production of short-chain fatty acids. 4 These fatty acids provide energy for colon cells and have anti-inflammatory effects.
Resistant starches contain prebiotic fibers that feed the good bacteria in your gut. This leads to a more diverse (a.k.a. healthier) gut microbiome. An improved gut microbiome leads to healthier immune function. It can also lead to a reduced risk of chronic diseases like cardiovascular disease and colorectal cancer. 5
Most Effective Resistant Starches
Not all resistant starches are equal, and some may be more effective than others. Evaluating the different resistant starches will help you make better dietary choices.
Evaluation of Different Resistant Starches
When it comes to resistant starches, it is important to consider the health benefits. Different types of resistant starches have different levels of resistance.
Food processing, cooking, and cooling methods can affect the levels of resistant starch. In food, the traditional African diet is high in resistant starch. Rural black South Africans consume an average of 38 grams of resistant starch per day. Cooked and cooled porridge and beans are staples.
A variety of resistant starches improves gut health, weight loss, and insulin sensitivity.
More Resistant Starches: Spotlight on Pea Starch
Among the various types of resistant starches, pea starch is a standout. It is high in resistant carbohydrates, making it an excellent addition to a healthy diet. Pea starch is also gluten-free, making it great for people with gluten sensitivity. 6
Pea starch is also a good source of dietary fiber and essential nutrients. It benefits digestive health, supporting regular bowel movements, and the gut microbiome. Adding pea starch into the diet is a simple and effective way to reap the benefits of resistant starches.
Are All Resistant Starches Keto-Friendly?
Not all resistant starches are good for the keto diet. Regular potatoes and rice, are high in carbohydrates and are not keto-friendly. But, Green bananas, pea starch, and uncooked oats might work.
It is always good to consult a registered dietitian to determine What may fit your dietary needs.
For those following a keto diet, including resistant starches can have great benefits. And you don't have to compromise carb intake. If you watch carb intake, there are several low-carb options.
Green bananas, raw potato starch, and whole grains are foods that are low in carbs and high in resistant starches. Careful food choices can support your health goals without breaking your keto diet.
Practical Tips for Introducing Resistant Starches
It isn't hard to introducing resistant starches into your diet. Here are some practical tips to help you incorporate resistant starches.
- Start small:
- Begin by introducing small amounts of resistant starches into your diet. Let your body adjust over time.
- Choose the right sources:
- Green bananas, rice, legumes, and pea starch are all great options.
- Cook and cool:
- Cook starchy foods, such as potatoes and rice, and then cool them to increase their resistant starch content.
- Combine with fiber:
- Pair resistant starches with fiber-rich foods, such as vegetables. This can help improve the digestion of foods like potatoes, rice, and bread.
