There are some answers for your reference as below,you can choose your best answers

Usually people say red but not white. That is usually connected to tannins.
Some people say it is the sulfates, scientific evidence shows there is no evidence for this.
Higher sugar levels may contribute to dehydration, do you drink sweet whites?
Cheaper wines have also been blamed for this, large commercial producers that blend left over bulk wine. Try a Spanish or Portuguese Alberano, or an Italian Vermentino. These wines are not made by bulk producers and are still very affordable and delicious.

It's hard to say without more info, but from what I have read some white wines actually have more sulfites than red wines. Red wine typically has a higher histamine content. Have you tried drinking any whites that are labeled organic? This may help. Sorry I couldn't be more thorough
