Avocados have more potassium than bananas and less glycemic load.
And "7.2 million Americans – didn’t know they had the condition. Only 11.6 percent of adults with prediabetes knew they had it."
How many people think they are able to make this choice based on personal preference while doing harm to their metabolic health? A1C tests are affordable without insurance.
89% were overweight or obese and 38% were physically inactive.
I dare say if you looked at the diets of those individuals, it wouldn't include many avocados' or bananas. I think you're splitting hairs.
per your edits, I don't disagree with you, but if you are in these metabolic states as nearly half of Americans are, there is a clear winner between the two and that's just a fact.
Additionally, for those that do not have insulin resistance, eating either a Banana or Avocado is not going to put you into any health risks. Infact eating either of them as part of a balanced diet with exercise is likely to have positive health benefits.
I'm not American, however in my opinion, people by and large aren't waking up with insulin resistance due to no fault of their own. It is due to lack of exercise and chronic consumption of high GI foods that aren't eaten in combination with a relatively healthy diet.
Depends if the reason is you want the most potassium possible. If I want to eat something prior to exercising, I'd be better off eating the Banana than the Avocado. However I understand if you are keto, potentially not.
I'll rephrase your point. Avocado's are a better source of potassium for those with IR who are looking for foods richest in potassium.
For what it's worth, raw unprocessed fruits (including bananas) are usually just fine for people with (pre-)diabetes, but you should talk to your doctor about your diet as one of the pieces of managing your (pre-)diabetes.
