Hello, health enthusiasts! Today, we’re going to delve into a fascinating video by Thomas DeLauer, a renowned health and fitness expert. The video, titled “White Potato vs Sweet Potato – Which is Really Better?”, provides a comprehensive look at the nutritional differences between white potatoes and sweet potatoes, and the impact they have on our bodies.
Meet the Creator: Thomas DeLauer 🌟
Thomas DeLauer is a health and fitness expert known for his YouTube channel where he shares his expertise on a wide range of health and wellness topics. In this video, DeLauer takes a deep dive into the science behind white potatoes and sweet potatoes, and their effects on our bodies.
The Video: A Scientific Exploration 🧪
The video is a detailed exploration of the scientific research on white potatoes and sweet potatoes. DeLauer discusses the glycemic index of both types of potatoes, their insulin release, and the factors that cause these differences. He also explains the concept of resistant starch and the benefits of consuming chilled potatoes.
The Science: White Potatoes vs Sweet Potatoes 🧬
Here are some key points from the video:
- Glycemic Index and Insulin Release: Both white potatoes and sweet potatoes cause a spike in blood glucose and insulin release. However, the spike is slightly lower for sweet potatoes. This is likely due to the more fibrous skin of sweet potatoes and the presence of anthocyanins, antioxidants that inhibit alpha-glucosidase, an enzyme that breaks down carbohydrates.
- Resistant Starch: When potatoes are cooked and then chilled, they form a type of starch called resistant starch. This starch is not easily digested, which leads to a lower blood glucose and insulin response. A study found that chilled potatoes had a 5% lower glucose response and a 25% lower insulin response compared to boiled potatoes.
- Gastric Inhibitory Polypeptides (GIPs): Both types of potatoes cause a similar GIP response, which happens quickly after consumption. However, the resistant starch in chilled potatoes affects the glucagon-like peptide in the lower part of the small intestine and the colon, indicating that these starches are fermented in the gut and act as fiber.

The Takeaway: It’s All About How You Cook It 🍽️
The video concludes that both white potatoes and sweet potatoes have similar effects on the body, and the way you cook them can significantly impact their nutritional value. Microwaving or steaming potatoes is better than baking them, and chilling them after cooking can lower their impact on blood glucose and insulin levels.
