I don't think it's one or the other - that you either consume enough carbohydrate to have glucose problems *or* you eliminate carbohydrate and cause other problems.
I've done menu sets with as little as 10g of carbohydrate and as much as 150g in an effort to highlight the nutrient density one can achieve at varying levels of carbohydrate in the diet, using different food sources.
"Zero-carb" is untenable simply because when you're focusing on nutrient-density, you'll include animal-foods and/or animal parts that contain some carbohydrate if you're doing nutrient-rich menus without plant-based foods - which is why I think it's a misnomer to call an all-animal-food diet "zero carb" - it's not if one gets totally picky-un and includes glycogen in muscle, which typically accounts for 1-2% of an animals carcass weight at slaughter (it varies by slaughter method since stress reduces glycogen stores if an animal is stressed before slaughter).
As I noted, some populations are genetically different for the homocysteine-folate cycle......at one end of the spectrum are those populations with very low incidence (some even zero incidence) of MTHFR polymorphisms - those populations, like the Inuit and sub-Saharan Africans require, genetically, less folate than the other end of the spectrum, those populations with the highest incidence of MTHFR polymorphisms, like that found so far in Japanese and French populations, whom require higher intake of folate to maintain health.
Worldwide the incidence of MTHFR polymorphisms is all over the place - and even in regional comparisons there are differences, like in Europe, there is a gradient of occurance of the gene mutations on a north-south lattitude.....the more north one goes, the fewer mutations found - the more south one goes, the more mutations found. Extremes of temperature play into it too, which is why in extreme cold (Inuit populations) and extreme heat (sub-Saharan Africa) less plant-based food is available, less folate is available in the diet, less genetic mutations requiring more folate is lower....basically, it's difficult to survive and thrive if you're genetically programmed to need more folate and you aren't getting it in your diet.
If you look at the dietary habits in different populations - all populations consume all the macronutrients, fat, protein and carbohydrate....the biggest difference across populations is the source and the quantity. It's kind of silly to say we shouldn't eat any carbohydrate, or even call it food, when everything we can eat - animal or plant - contains carbohydrate.
It's excess carbohydrate, from any source, refined or whole, that causes metabolic problems....one doesn't have to consume excess carbohydrate to meet nutrient requirements, but if one has genetic predispositions that require higher folate, than including folate-rich foods is a good idea and most non-starchy vegetables, that have low carbohydrate content, aren't going to be a problem for glycemic control.
1-cup of spinach (cooked)
1-cup of asparagus (cooked)
Total Carbohydrate = 14g
Fiber = 8g
Net Carbs = 6g
FOLATE = 525mcg
----------------
2-ounces calves liver, braised
Total Carbohydrate = 3g
FOLATE = 430mcg
---------------
If we are to consider the "lessons of tradition" then we don't eat liver daily, as populations that rely on animal foods won't eat liver daily or eat it in large quantity when they do.
At the end of the day, IMO, you want to avoid excessive carb intake....small amounts are not problematic and to say such is to ignore that even animal foods contain carbohydrate.
