McDonald's French Fries

Low histamine

McDonald's fries are low in histamine, just potato, oil, and salt.

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.

These are simply potato cut into fries, cooked in vegetable oil, and salted, which keeps them low.

  • Potato — potato is naturally low in histamine, and none of the ingredients here bring any aged, cured, or fermented element.

  • Oil and salt — the frying oil and salt are fresh and mild, so nothing in the recipe lifts the level.

These are one of the friendlier picks on the menu.
