Intake Record Consultation: Facial redness after eating, what should I write?

I experience facial redness after eating, so I would like to inquire about what I should organize before my consultation. When filling out a 'food intake log,' would it be helpful to record the type and amount of food consumed, the time of the meal, when the redness started, and the time it took for it to subside?

I am wondering how many days I need to collect records to examine whether there are differences depending on the situation, even when eating the same food. Are there any materials I should prepare before the visit, such as photos of meals or ingredient lists on food packaging, that would be helpful for the consultation?

I would like to receive a consultation based on my records without prematurely assuming the cause. Please advise on what details I should include regarding my skin condition and changes before and after meals, as well as any items I should not miss when organizing my questions before the visit. Thank you.
