This is a good question and encapsulates the challenges of food and drug regulation. Yes and no. At certain concentrations, many safe compounds become dangerous in humans. Even at tiny doses, foods like peanuts may be safe for the vast majority yet lethal for a minority. Given how devilishly heterogeneous the human race is, the ideal solution provides safety testing at the individual level, not the population level [0]. But this is years away until computational and biological breakthroughs arrive. [0] Population level is a misnomer. FDA trial sizes below. Phase 1: 20 to 100 people Phase 2: up to several hundred people Phase 3: 300 to 3,000 people https://www.fda.gov/patients/drug-development-process/step-3-clinical-research https://www.fda.gov/patients/drug-development-process/step-3...
