There is obviously a lot to unpack here, most of it is just plain gibberish. The best option here, as always, is to ask him directly.

Pro: Fresh white bread can be very delicious. It is soft and fluffy, and depending on the freshness even still warm, which are all really nice things to be associated with imho. It is also versatile, as it can be crafted to e.g. a list of delicious sandwiches. The focus on the whiteness of the bread may be in remembrance to a time when paleness was a female beauty standard.

Contra: It is not the healthiest choice of breads, but not a lot of wheat products are. If I’m not mistaken, it could also be a slur for people with a light skin tone.
