Why can food coloring give you cancer?

The report reveals that common food dyes pose risks of cancer, hyperactivity in children, and allergies. The food industry dumps over 15 million pounds of the dyes studied into the food supply each year. Three of the dyes carry known carcinogens, and 4 can cause serious allergic reactions in some consumers.

here. I found this for you. don't know how accurate but it may help.

10/10 recommend bring pads/tampons with you no matter what. im 16 & i’ve had mine since i was 12 and they’re still it regular, but id suggest using the glow app, many women use it for fertility reasons but i use mine specifically for the period tracking portion and it guesses when your next period will most likely be for the next two months. i dont believe theres any way to delay your period, so id say hope for the best but make sure to bring all of your stuff just incase. have a good cruise!
