riboflavin
?
Normal food that fluoresces by itself — vitamin B2 / riboflavin, tonic water (quinine), and white chocolate
Also:
Tumeric / curcumin
Also: A
chlorophyll-rich herb infused oil
will glow red.

Note: Riboflavin is excreted in urine only, and doesn't pass with stool.
Quinine has low-ish toxicity levels.

"Food Colors as Intrinsic Luminescent Sensors in Edible Products."
Biophysical Journal
108.2 (2015): 623a.
"The research team tested the fluorescent properties of five edible food colors that are routinely added to food or pharmaceuticals: Allura Red, Sunset Yellow, Brilliant Blue, Fast Green and Tartrazine"
Allura Red AC FD&C Red 40 E129
a different document says
"The dye fluorescence is weak, often undetectable, in low viscosity fluids; however, its quantum yield, emission intensity and lifetime increase significantly with an increase in medium viscosity."
Sunset yellow FCF FD&C Yellow 6 E110
Brilliant blue FCF FD&C Blue No 1 E133
"Brilliant blue FCF is extensively used as a water tracer agent."
Fast Green FCF FD&C Green No 3 E143
"Fast Green FCF is poorly absorbed by the intestines."
Tartrazine FD&C Yellow 5 E102
