The Super Starch

What Does a Bean Salad have in common with a green Banana? The answer is resistant starch, and a lot of it. If you’ve never heard the term Resistant Starch (RS), you’re not alone. These days, in our carbophobic society, many of us spend more time fearing starches than we do understanding their nutrient power potential. When it comes to healthful starches, RS is no BS. This type of indigestible starch (a large complex carbohydrate used by plants to store energy) has been shown in many human studies to benefit digestive health, as well as manage appetite, improve insulin sensitivity, lower blood cholesterol and triglyceride levels, improve satiation, and lower colon cancer risk. These benefits can translate to a healthier, even slimmer body, and make resistant starch a powerful weapon in your fitness-boosting meal plans.

Quit avoiding the S-Word. These food contains starch that improve digestive health and keep cravings in check.

“Resistant starch is found in the plant cell walls of seeds, beans, and grains,” explains Joy McCarthy, a Toronto-based holistic nutritionist. “Basically, it doesn’t get digested and converted into glucose the way
a normal starch would.” So where can you find this super starch? Just look in your refrigerator’s crisper. Raw and slightly cooked veggies contain more RS than fully cooked or hot ones. You can also find it loaded in unripe bananas, raw potatoes, and legumes that have been cooked and cooled, says McCarthy,
who likes to get her resistant starch fix in the afternoon by noshing on raw veggie sticks dipped in hummus.

Go with your gut

When eaten, resistant starch goes through the stomach and small intestine, acting like soluble fiber, which dissolves in water and is metabolized by the hundreds of species of friendly bacteria in the large intestine. This is good news if you’re concerned about your digestive health, says Elizabeth Brown, MS, RD. “Happy gut bugs ward off potential invaders,” she says. “They make vitamin K and biotin for us, they help regulate cholesterol production and they send signals to the brain to help you feel full.”

Did you know? Raw veggies are higher in resistant starch than hot, cooked ones. For a mega dose of RS, try snacking on raw sweet potato sticks instead of carrots.

Another positive outcome of consuming RS is the spike in the production of a fatty acid called butyrate. Butyrate is the preferred fuel of the cells that line the colon and protects it from inflammation and rising PH levels. In turn, this helps lower the risk of colon cancer, which affects 1 in 6 women during her lifetime.

The Four Types

Based on the properties that allow resistant starch to resist digestion, RS is grouped into four classifications:

  1. type 1 is found in whole grains, legumes and seeds, and physically resists digestion because it is bound within a protective coating.
  2. type 2 is intrinsically resistant to digestion before cooking. This group of foods includes unripe bananas and uncooked potatoes.
  3. type 3 is formed when starchy foods are cooked and then cooled.
  4. type 4 is chemically modified to resist digestion and absorption, and these starches are often developed for use in processed foods.

How to increse your RS

Some people can experience bloating and upset stomach when they try to introduce more fibrous foods into their diet. “I often see many people shy away from foods that cause even the slightest digestive issue,” says Brown. “But sometimes we need to give good food a chance.” McCarthy recommends gradually starting with 20-40 grams daily. Go slowly and “pay attention to how your body feels,” she warns, citing that many of her clients do not feel great eating raw foods, which contain the highest amounts of resistant starch. “Additionally, anyone with digestive issues such as an overgrowth of small intestinal bacteria, IBS or inflammatory-type conditions such as arthritis may find that resistant starch makes their symptoms worse.”

The digestive health and appetite suppressing benefits of resistant Starch make it a powerful weapon in your fitness-boosting meal plans.

As a former bodybuilding competitor, Brown used to eat cold potatoes in her college days as part of her figure building diet. “I grossed out my classmates,” she says. Now a holistic chef in Santa Monica, CA (TheKitchenVixen.com), Brown is an expert on sneaking resistant starch into meals that fitness-minded women are already eating on a regular basis. In fact, she says “foods rich in resistant starch are likely already a part of a seasoned body builder or any athlete’s diet.” But there are endless possibilities on how
to be more creative in the kitchen with RS.

Try some of her suggestions:

  • Add beans to soups and casseroles. Especially in the presence of water, as in soups, the bean fiber and resistant starch will enter the digestive tract more gradually than if you simply ate forkfuls of beans.
  • Toss cooled beans in smoothies. Instead of using oats or yogurt for thickness, blend cooked and cooled white beans or chickpeas into your protein smoothies. Pureeing may lessen some of the resistant starch benefits by exposing more surface area of the bean to digestive enzymes, but in the end, you’ll still be getting more nutritient bang for your buck.
  • Yes you can grind seeds. Many people are hip to adding ground flax, chia or hemp seeds to smoothies. These seeds are better known for fat and fiber than they are for starchy carbs, so don’t be afraid to grind them first in the coffee grinder.  More starch will be exposed to digestive enzymes but the starch is the smallest component of these seeds anyway. The more important components of these seeds are really their Omega-3 fats, phytonutrients and fiber.
  • Eat more cooked and cooled starches. Try a cold rice salad with fresh herbs, peppers, homemade lemonor balsamic vinaigrette and some pumpkin or sunflower seeds. You can do the same with pasta salad, as it too has more resistant starch once cooked and cooled. Plus, it’s a perfect pre-made snack or lunch for the week.
