Too funny! They didn't even tested Sucralose because they knew that it couldn't cause cognitive decline because it is produced by chlorination of sucrose, selectively replacing three of the hydroxy groups—in the C1 and C6 positions of the fructose portion and the C4 position of the glucose portion.
Table salt is Na-Cl, and Sucralose is C12-H19-Cl3-O8. No big deal.
“They didn’t even tested Sucralose because they knew that it couldn’t cause cognitive decline”
They know nothing about sweetener’s effect on cognitive decline, neither from sucralose, nor from any other substance.
This study is garbage, like any other nutrition “science” based on food questionnaires, uncontrolled samples, unknown physiological mechanism, fudge (’adjusting’) factors, results scouting (they didn’t test for an a priori hypothesis, they pull post-hoc conclusions out of their hats), unsignificant risk factors, irreproducible results...
Pure junk science, dressed up as “epidemiological research” to make headlines and appeal to suckers and snake oil seller. Nothing can be concluded from it, much less informed dietary advice.
