Not surprisingly, white potatoes rank high on the glycemic index (GI), which measures how much a particular food raises blood sugar levels compared to pure glucose (glucose rates 100 on the glycemic index). According to Harvard Medical School, a baked white potato has a glycemic index of 111, which means that it raises blood sugar 111% as much as pure glucose! Sweet potatoes have a lower GI of 70.
While the GI of sweet potatoes might also seem high, sweet potatoes are shown to modulate and even improve blood sugar regulation! Sweet potatoes contain adiponectin, a protein hormone produced by fat cells that modulates insulin metabolism. Low levels of adiponectin are associated with people who have poorly-regulated insulin metabolism, while those with healthy insulin metabolism tend to have higher levels of adiponectin. So, while sweet potatoes are safe for even diabetics to eat, they should avoid consuming high GI white potatoes.
Good to know about the yeast infection connection w/sweet potatoes. I have one very yeasty pup & need to avoid all carbs, including sweet potatoes. |
Dogs don't eat plain baked potatoes. Looking at the GI Index for a stand alone ingredient doesn't translate in kibble where all the ingredients are mixed together. You have to look at the combined meal. Do you ever have just a plain solitary baked potato for dinner? No, you have a salad, meat of some kind, a glass of milk maybe and a vegetable.
You are right the index is 111 for baked russet potato but is 94 for baked sweet potato.
The Gylcemic Load is more important anyway and white potato is much much lower, 25% lower probably because sweet potato has so much sugar.
Given the oxaxlate levels, phytoestrogen levels as well as the fact sweet potato have up to 3 times the level of sugar. White potato is a better option.
