Tim Hortons Strawberry Watermelon Poppin' Candy Dreamsicle

High histamine

This creamy frozen drink is high mainly because of the buttermilk in its base.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

Dairy

It layers a fruit blend of apple and watermelon concentrates with a creamy dreamsicle base made from buttermilk, cream, lactose, and various stabilizers, plus poppin' candy.

Buttermilk — buttermilk is a cultured dairy product, and cultured dairy tends to run high, which is what pushes this drink up.
The rest is milder — the apple and watermelon concentrates and the sugars are gentler on their own, so the creamy buttermilk base is the real driver.

Skipping the creamy base for a plainer option lands much lower.
