Sorry legit haven’t read the article but sounds like you have, so I’ll ask for clarity
Would that be the equivalent of a 15% daily recommended dose, as adjusted by weight for a rat, or is it literally 15% of the daily allowance of a human, pumped into the rat? Because the latter is definitely more of what vibe I get from the previous poster.
When a sample of mice were given free access to water dosed with aspartame equivalent to 15 percent of the FDA’s recommended maximum daily amount for humans, they generally displayed more anxious behavior in specially designed mood tests.
Cool, so it’s 15% of the RDA for humans, divided by whatever the avg weight difference between a rat and a human is, right? Or similar? That’s the best interpretation of that quote, though it is still a bit ambiguous lol
Here’s the relevant sentence in the study:
The FDA recommended maximum DIV for aspartame for humans is 50 mg/kg (33). Based on allometric conversion utilizing pharmacokinetic and body surface area parameters (43), the mouse equivalent of the human DIV is 615 mg/kg/d. Therefore, the male mice received a daily aspartame dose equivalent to 14.0%, 7.0%, and 3.5% of the FDA recommended human DIV, and the females received a dose equivalent to 15.5%, 7.7%, and 3.9% of the human DIV.
It’s a lot to unpack, but my interpretation is that it’s been adjusted for a rat
To translate that into something sensible, the RDA in the US is 50 mg/kg = 110.25 mg/lb. 15% of that is 16.5 mg/lb. So 1653 mg per 100 lbs of bodyweight.
A can of diet coke is about 200 mg of aspartame. So that’s a bit over 8 cans of coke per 100 lbs of body weight. Or 1.5 2-liter bottles per 100 lbs.
That’s… kinda a lot.
