Two friends drink the same amount at the same pace; one ate a full meal beforehand, the other drank on an empty stomach. How does the meal actually affect their blood alcohol levels?

Why C is correct

Food in the stomach slows the passage of alcohol into the small intestine, where most absorption occurs. The practical result is a lower, later blood-alcohol peak for the same quantity of drinks — a real and meaningful difference — but it is a delay in arrival, not a deletion: every gram of alcohol consumed still ends up in the bloodstream eventually and leaves only at the rate the liver processes it. The meal changes the shape of the curve, not the amount of alcohol on it, which is why 'I ate dinner' is a fact about timing and never an exemption.

Why the other options are wrong

A. Food converts alcohol into water and speeds its elimination

Conversion to water does not happen in the stomach. Alcohol leaves the body chiefly by being metabolised by the liver at its own fixed pace, and no food changes that pace materially.

B. Food neutralises alcohol, so the driver who ate has no alcohol in their system

Neutralisation is a myth with real casualties. No food chemically removes alcohol; it only moderates how fast the same alcohol reaches the blood, and the drinks all arrive in the end.

D. Food has no measurable effect on blood alcohol at all

'No effect at all' overstates the opposite case. The meal genuinely lowers the peak — that is measurable — but the flattening of the curve is the whole of the effect, and treating it as no effect misleads in the opposite direction.

On the road

Two identical evenings, one variable: dinner. The friend who ate reaches a muzzy peak an hour in and levels off; the friend who drank fasted rockets past the same point at forty minutes and feels it harder, longer. Same bar tab, different curves — and by closing time, both bloodstreams hold every gram either of them drank.
