Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will be removed and our normal comment rules apply to all other comments.

"In high doses" is the salient fact here.

In high doses, yes — but not in doses so high that it would be absolutely infeasible for a person to consume.

These compounds are so small I imagine you could fill a pill with it to avoid the overwhelming sweet taste to get up to the recommended doses if it worked.

That is pretty cool, overactive immune systems can be debilitating, and these sugar substitutes are so common, and the costs are going down with use in drinks, it probably would be a pretty inexpensive intervention too.

I read through and the implication that a low-cost intervention like this would have literally ANY impact on diabetes is amazing.

Max safety dose. Maybe they should lower that limit.

So instead of paying 1000usd per tablet of any immunosuppressive drug, just hit the 2 bottles of good old Coca-Cola.

From OPs reference: "The researchers did not investigate the sweetener’s effects in humans, and say that it is unlikely that normal consumption of sucralose is harmful."

1. This is a relatively naive comment and underestimates diet soda *addiction*, certainly in the US.
2. The singular conclusion that sucralose can help replace immunosuppression therapies - without addressing the obvious question, what is the effect of sucralose on the global immunosuppression of its users, seems to be a missed opportunity. It follows that we would want to understand if we have a public health issue not so much whether we have a new immunosuppression therapy.

Edit: minor grammar

I'm sure some people in this world consume an unholy amount of sucralose.
