Fooducate is mostly a very good blog. Their byline is "eat a bit better" and that's exactly what it'll help you do. They try to push for food that is closer to natural and call our attention to food marketing lies. But... they are still attached to conventional wisdom. Had a hard time reading their latest post.
because of gems like
Myth #1: People with diabetes need to drastically reduce their carb intake.
WRONG! In healthy adults, carbs should account for 45-65% of total calorie intake. People with diabetes should be in the lower range, but not below the 40% mark.

Not feeling like this a very high quality article. One quote was one I took issue with:
"Saturated fat has been demonstrated to be a cause of insulin resistance, one of the key symptoms of diabetes and prediabetes".
Here's a study on diabetics (link) which found that "Addition of saturated fat and removal of starch from a high-monounsaturated fat and starch-restricted diet improved glycemic control and were associated with weight loss without detectable adverse effects on serum lipids".
There are more randomized trials failing to find a risk of saturated fat on insulin resistance, like the RISCK trial (link) which the authors concluded "did not support the hypothesis that isoenergetic replacement of SFAs with MUFAs or carbohydrates has a favorable effect on (insulin sensitivity)".
Or there's the LIPGENE trial (link), which found "There was no effect of reducing SFA on SI in weight-stable obese MetS subjects".
So really, where is the evidence demonstrating saturated fat is a cause of insulin resistance? If we're gonna blame a type of fat for IR, I'm looking suspiciously at omega-6 vegetable oils (4, 5, 6, 7).
The article went on to say:
"A proper, balanced diet, with a focus on calorie reduction, may help people with prediabetes stave off type 2 diabetes. But once a person is diagnosed with Type 2 diabetes, medication is just a matter of time. Studies have shown that only a small fraction of people at the onset of type 2 diabetes were able to postpone any type of medication through intensive lifestyle changes"
So if you have T2D you have no hope of getting off your medication? Is that what they're saying? Here is a quote from a diet trial (link) on 84 diabetics: "The diet lower in carbohydrate led to greater improvements in glycemic control, and more frequent medication reduction/elimination than the low glycemic index diet...Twenty of 21 (95.2%) (low carb ketogenic) group participants had an elimination or reduction in medication".
The articles outright dismissal of low carb diets for diabetics is frankly silly in my opinion. I don't even think all diabetics need to be low carb, but the evidence that it helps a lot of them treat their condition seems difficult to deny with a hardheaded claim that diabetics should never eat less than 40% carbs.

The sentence should have continued with "and remain reliant on Big Pharma to control your glucose levels for you."

Disclaimer: not a diabetic.
As someone that eats 25%-35% carbohydrates (and 35% is on a very heavy day, usually to prep for training), I find this quite sad.
I actually found this paragraph of "Myth #1" more insane:
Additionally, less carbs in the diet means more fat and protein. Often these choices lead to higher levels of saturated fat consumption. Saturated fat has been demonstrated to be a cause of insulin resistance, one of the key symptoms of diabetes and prediabetes.
I think Stephen Guyenet address this best here: http://wholehealthsource.blogspot.com/2010/02/saturated-fat-and-insulin-sensitivity.html
However, there was this gem that I agree with: Our cookie to kale ratio is the problem, not carbs.
