I had forgotten to look up lettuce - seems that they all have fructose in them too - all at slightly higher amounts than the glucose in them. There may have been very small amounts overall, but given the overall amount, there's no logic to putting them on the low fructose list, while zucchini and asparagus made the high fructose list.



I couldn't find a breakdown of the sugars in spinach or kale, but based on the apparent criteria for the Mayo Clinic list, broccoli should have made the high fructose list, while potatoes should have made the low fructose list.






Even though I couldn't find a breakdown of the sugar content of a lot of typical LC veggies, most vegetable matter contains a mixture of glucose, sucrose, fructose, and maybe a couple other types of -ose (galactose, maltose). We know that all fruits contain fructose - after all fructose is fruit sugar. But there's also some in most veggies, even if a very minimal amount.
