A 60 kg individual uses a brand of saccharin with an ADI of 5 mg/kg. Each single-serve packet contains 36 mg of saccharin. How many full packets can the individual consume in one day without exceeding the ADI?

• A. 8 packets per day (8 full packets keeps intake under the ADI).
• B. 5 packets per day because only natural sweeteners should be used daily and synthetic saccharin requires additional safety margins beyond the ADI.
• C. 12 packets per day, since ADI estimates are overly conservative and typical consumption is safe even at double the ADI.
• D. 9 packets per day, because the ADI should be rounded up to allow practical consumption and packet sizes vary slightly between brands.

Answer: (A)
