The Last Word on Potatoes

It’s probably not the last word on potatoes. After all, we still have to address the health benefits of French fries! I’ll use the name of the day to more easily explain the sequence of what happened. On Wednesday evening, I carried on exploring the effects of potatoes on my blood sugar. This time, I managed to avoid my sugar-laden dessert. I knew that wasn’t going to be easy so I decided to have two full-sized spud dinners to combat the urge. We’re not talking seconds here, we’re talking two full dinner-sized portions. The first was leftovers from Tuesday, the potato & Brussels sprouts combo. The second was again made from boiled & cooled potatoes, pan fried in olive oil. Then drizzled with more olive oil because they just don’t bring any fat to the party. I added the usual chopped onion, herbs & seasonings. This one also got a shot of store-bought Jalapeño-Lime Aioli. Which I probably shouldn’t have done, but it’s just so good! And I also melted three slices of Jarlsberg cheese into each serving. While potatoes have some protein, the cheese adds more of that, along with some excellent texture & flavour. I was probably a little below my protein requirement on both days but not enough that I worried about it. And it’s only for a couple of days.

From Tuesday’s eating, it took ’til early afternoon Wednesday to get back down to 5.6 mmol/l (101 mg/dl). Remember that I had that sweet dessert on the Tuesday though. The numbers aren’t really all that bad but I’m used to being lower, and faster getting there, on low carb days. Was that difference in glucose decay caused by the sugar in the dessert? Or the fact that I had been low carb for the week prior & my body needed to readjust to handling the carb load again? Am I over producing insulin in reaction to that? And is that insulin just helping transport it out of my blood & into muscle for use? Or is it driving all the excess to my belly for storage as fat!

I don’t know. None of the readings were serious enough that I’m worried so I’ll just ignore it for now. Just before dinner on Wednesday, I was back in my happy zone, at 5.1 mmol/l (92 mg/dl). Pretty much immediately after the hour long feast, it hit 7.1 mmol/l (128 mg/dl). One hour later it was 7.2 (130 mg/dl) & it was back down to 6.3 mmol/l (113 mg/dl) at the two hour mark. By the three hour mark, it was down to 5.8 mmol/l (104 mg/dl). On Wednesday, with the potato binge only & no dessert, the glucose decay was much better, & faster. From a blood glucose perspective, I’m okay including the occasional potato binge.

From a weight loss perspective, the story doesn’t necessarily end there. Potatoes may trigger a greater insulin response than the blood glucose number would suggest. So does that mean that I’m getting fatter while I overindulge on them?

Not according to the scale on Thursday morning. Phew!

Think I’ll have to check the impact of wine & beer with that little glucose meter too! 🙂
