Sweet potatoes have been erroneously reported as the healthier potato because the size used for comparison was a Russet that’s 52% larger in weight! How did so many trusted nutritional professionals and reliable resources get this nutrition fact so wrong?
Sizes like small, medium and large are most familiar to the general population and easiest to visualize. The problem is the weight for each medium sample on the USDA’s website isn’t the same, see USDA images below.
When it comes to starchy carbs like potatoes, the carbohydrate content is potentially impacted by baking. That’s why it’s also noteworthy that only the USDA’s medium sized sweet potato is “raw”, while all the other sample sizes are baked. We’ll save that investigation for a future post.
After the World Health Organization published their “Healthy Diet Fact Sheet” the reference to all potatoes caught my attention. They specifically point to “potatoes, sweet potatoes, cassava and other starchy roots” are not classified as either fruit or vegetables, see image below. I understood that statement to say, “all potatoes are equally unhealthy”.
Nutritional professionals and reputable resources like Cleveland Clinic and image below from the University Health News, all pointed to the same USDA nutrition facts as their resource and all used the same erroneous “medium” size for nutritional facts comparison and conclusions.
Enjoy the type of potato you like most, on occasion, as an exception. Potatoes, no matter what the kind, are a high starch root carbohydrate that will reliably spike blood sugar. There is not enough natural fiber in any potato to effectively slow the insulin response.
It’s normal to look to confirm what we already believe. But in the case of potatoes, we got a compelling incorrect narrative that was promoted by nutrition professionals and food manufacturers. Now we know better, it’s more proof that it’s time to update what we know to be true about food and healthy eating.
