OK, I am going to try arguiung that privacy supersedes food:

To have a right to anything means there is something that I own. Owning something puts a division between me and others who can not own this specific thing: My right is my own, I do not have to diminish it by sharing. The most fundamental form of division is absence. Having a right to privacy is a right to the absence from others. Therefore the right to privacy is a more fundamental one than the right to food.

However, I agree that in practice eating in public beats dying in private any time of the day. 🤷
