Knowledge about carbohydrate-rich food was derived from 11 items designed around type and source of carbohydrate, food processing, and nutrition. Each item was scored 1 point for correct answer, − 1 for incorrect, and zero point if participants selected ‘do not know’. The score was summed, giving a range from − 11 to 11.

Dietary guideline awareness and agreement
To assess awareness of the current dietary guidelines, participants were asked whether they had heard of the UK Eatwell plate/guide (or MyPlate, USA) and whether they were following one of these guidelines. They were also asked whether they agreed with these guidelines, including agreement on each of the four statements in the UK Eatwell guide (i.e. carbohydrate foods, fruits and vegetables, oils, and foods high in fat, salt and sugar). To assess the level of agreement on UK Eatwell guide, each of four statements scored 1 point if respondents answered ‘agree’, − 1 for ‘disagree’, and no point for ‘not sure’. The score was summed, giving a range from − 4 to 4.

The above two items, a "high carbohydrate knowledge" plus agreeing with the UK Eatwell that one should eat lots of carbs, consume industrial seed oils and avoid saturated fats, were negatively correlated with use of low carb diets. The eleven question test of "carbohydrate knowledge" wasn't included in the article so no way to check my suspicion that questions were biased such that disagreeing with purported health benefits of carbohydrate scored as a wrong answer, therefore those who believe high carbohydrate intake isn't healthy would generate a low "carbohydrate knowledge" score. Labeling the test "carbohydrate knowledge" reveals more bias IMO. If you agree lots of carbohydrates are good (like the authors?) you have knowledge. But if not...?
