Sweet potatoes vs white potatoes impact on blood sugar levels

Depends. Potatoes are a definite no no for me. Sweet potatoes, small amount in a stew is OK. Don't try and make them into roasties though. Baking changes something and will spike something rotten (at least for me). Taste and test.

 

Sweet potato contains high starch, high sugar content, about 23.1%, and is easily digested and absorbed and decomposed into glucose, which is prone to postprandial hyperglycemia. It is best for people with diabetes not to eat or eat less sweet potatoes.

 

Treat sweet potato and white potato in the same way as the end result is the same, one just takes a little longer to get there than the other.

 

actually the OP is a type 1 diabetic and can therefore eat as many (or few) carbs as they like. @Villovigo ’s question was about which of the two foods requires more injected insulin, not whether those foods should be eaten or avoided.

 

I have no intention of avoiding sweet potato, I calculate the carbs, inject and Voila!

 

@Brunneria

I understand your point but the above was part of the post and the answer I think not dependent on what type you happen to be also the post was prefaced with out of curiosity and was asking how different people react and therefore treat the two similar foods

And also insulin doses do have to be calculated for amount carbs eaten and how fast those carbs are absorbed may have a bearing as the op made plain or so I believe.

 

I agree with you.
So it makes sense not to let this thread derail into a discussion on how lowering carb intake, or eliminating specific foods is the answer - because that would be a discussion for a different question, and a different thread.

 

Do you allow for the .1% or do you round up or down accordingly?

 

Last time, I measured after 2 hours my dad ate 100g microwave sweet potato, the result showed the blood sugar level is not too good. So I do not give him sweet potato anymore as a carb source.

 

I’m not a T1, but I find sweet potatoes spike me about 3-4 hours after eating them, so for me they are a no-no. As are ordinary potatoes.

 

Your results may show that glycemic index might be overrated.
