What is Potato Starch?
Potato starch, also known as resistant starch or MSPrebiotic, is a type of dietary fiber that comes from potatoes[1][2]. It’s called “resistant” because it resists digestion in the stomach and small intestine, allowing it to reach the colon intact. This unique property makes it a valuable prebiotic, which means it feeds the beneficial bacteria in your gut[2].
Health Conditions Potentially Treated with Potato Starch
Researchers are exploring the use of potato starch in treating various health conditions:
- Cancer treatment side effects: It’s being studied in patients undergoing cancer treatment with dual immune checkpoint inhibitors (ICIs) for solid tumors[1].
- Gulf War Illness (GWI): This condition affects many veterans who served in the Persian Gulf War, causing symptoms like pain, fatigue, and gastrointestinal issues. Potato starch is being investigated as a potential treatment for GWI-related gut dysfunction[2].
How Potato Starch Works
Potato starch works by influencing the gut microbiome, which is the collection of microorganisms living in your digestive tract. Here’s how it functions:
- Prebiotic effect: It serves as food for beneficial gut bacteria, potentially improving the balance of your gut microbiome[2].
- Short-chain fatty acid production: When bacteria in your colon ferment the potato starch, they produce beneficial compounds called short-chain fatty acids (SCFAs)[2].
- Modulation of gut environment: By changing the composition of gut bacteria and increasing SCFA production, potato starch may help reduce inflammation and improve overall gut health[2].
Dosage and Administration
The dosage of potato starch can vary depending on the specific study or condition being treated. Here are some examples from ongoing research:
- For cancer patients: 20g of potato starch once a day for 3 days, then increasing to 20g twice a day, continuing throughout treatment (about 13 weeks)[1].
- For Gulf War Illness: A gradual increase starting with 4g daily for 4 days, then 7g for 3 days, and finally 10g daily from day 8 onwards for a total of 4 weeks[2].
It’s important to note that potato starch should be mixed into cold or room temperature foods or beverages and should not be heated. Additionally, it should be taken at least 2 hours before or after any medications[2].
Potential Benefits
While research is ongoing, potato starch may offer several potential benefits:
- Improved gut health and microbiome composition[1][2]
- Reduced inflammation in the gut[2]
- Alleviation of gastrointestinal symptoms associated with conditions like Gulf War Illness[2]
- Potential improvement in overall quality of life for individuals with certain health conditions[2]
Safety and Side Effects
Potato starch is generally considered safe and well-tolerated. However, as with any supplement, there may be potential side effects or risks:
- Mild gastrointestinal discomfort, especially when first starting the supplement
- Possible interactions with medications (hence the recommendation to take it 2 hours apart from other drugs)[2]
Researchers are closely monitoring for any adverse events in ongoing studies to ensure the safety of potato starch supplementation[1][2].
Ongoing Research
Several clinical trials are currently underway to further investigate the potential benefits of potato starch:
- A study examining its use in cancer patients receiving immunotherapy, focusing on how it might affect treatment side effects and the gut microbiome[1].
- Research on its effectiveness in alleviating symptoms of Gulf War Illness, particularly gut-related issues[2].
These studies aim to provide more concrete evidence on the effectiveness and safety of potato starch as a dietary supplement for various health conditions.
