This seems pretty high considering they're only following people for 6 months. I guess people are most likely to have side effects at the beginning, but I feel like I've not gotten the sense that a third of people bail within the first year, due to side effects or other reasons.
The data might really be useful for the food industry once, but only after the usage of the medicine goes beyond 16% currently. 5-8% change, even 10%, for 16% of the population is tiny.
To me the study sounds desperate to project significance, using adjectives rather than data for seeking attention.
