Cooked and Cooled Potatoes Resistant Starch: What Do You Really Gain?
Cooked and cooled potatoes resistant starch is modestly higher than in hot potatoes. Harvard Health reports a rise from 3.1 to 4.3 g per 100 g in russets and calls the effect probably modest at best. A SodaTide capsule prints 100 mg, or 0.1 g, of potato resistant starch, about 43 times less than that serving.

The numbers01
What happens to cooked and cooled potatoes resistant starch?
Yes, a little more. Cooling a cooked russet potato raises its resistant starch from 3.1 to 4.3 g per 100 g, according to Harvard Health, which calls the effect "probably modest at best". (Harvard Health, Resistant starch)
Resistant starch is starch that escapes digestion in the small intestine and is fermented in the colon. (Cleveland Clinic, Resistant starch) We could not confirm from our sources how long to cool a potato, or how reheating changes the figure.
Other potatoes02
Do sweet potatoes have resistant starch?
We could not confirm it. The sources we read report numbers for russet potatoes only, and none gives a figure for sweet potatoes.
That gap matters because a number from one food should not be moved to another. The same caution applies to capsules.
| Food or product | Figure |
|---|---|
| Russet potato, after cooling | 3.1 to 4.3 g per 100 g |
| Sweet potato | Not confirmed |
| SodaTide capsule | 100 mg (0.1 g) of potato resistant starch |
| Average US intake, per day | About 4 to 5 g |
Your plate03
How does a potato serving compare with your fibre target?
A cooled russet serving is a small piece of a bigger fibre picture. The FDA sets the Daily Value for fibre at 28 g. (FDA, Daily Value on the Nutrition and Supplement Facts labels)
US intake of resistant starch is about 4 to 5 g a day. One 100 g cooled serving at 4.3 g would therefore be close to a full day's average. We could not confirm whether resistant starch counts toward the fibre line on a food label, so use the tool as a rough fibre tally only.

0 g typed so far. The FDA Daily Value for dietary fibre is 28 g on a 2,000-calorie diet (FDA, Daily Value on the Nutrition and Supplement Facts labels).
Fibre that ferments in the gut can cause gas and bloating, mostly when intake rises quickly (Mayo Clinic, Dietary fiber). The label amounts are far below the gram doses used in most trials. Your own numbers stay in your browser tab and are never sent anywhere.

Is a cooled potato the same as a resistant starch capsule?
No. A cooled serving gives grams, and the SodaTide label prints 0.1 g. That gap neither makes the capsule safe nor unsafe.
Fermentable fibre can cause gas and bloating, from food or capsules, so raise fibre slowly with water. (Mayo Clinic, Dietary fiber) Ask a doctor or pharmacist first if you take medicine, have a condition, or are pregnant or nursing. The how to use page gives the label directions.
Honest line: a potato is food, and the capsule's benefit is unproven.

FAQ05
SodaTide questions people ask
Is the cooked and cooled potatoes resistant starch gain worth it?
It is small. Harvard Health reports a rise from 3.1 to 4.3 g per 100 g in russets and calls the gain probably modest at best.
Do sweet potatoes have resistant starch?
We could not confirm it. No source we read gives a sweet potato figure, so we will not guess one.
Can you reheat cooled potatoes and keep the resistant starch?
We could not confirm it from our sources. They do not describe reheating, so follow food safety advice for leftovers.
