What it is

Partially hydrogenated oil (PHO) is a type of fat created when liquid vegetable oils undergo a process called partial hydrogenation. This process adds hydrogen atoms to the oil, changing its chemical structure and making it more solid at room temperature.

Why it's used

Historically, PHOs were widely used in many processed foods because they provided a desirable texture, extended shelf life, and were less expensive than butter or other solid fats. They were common in baked goods, fried foods, snack foods, and stick margarines.

Health notes

The FDA determined in 2015 that partially hydrogenated oils are no longer generally recognized as safe (GRAS) for use in human food, with the compliance date for this determination being 2018. This action effectively removed most artificial trans fat from the US food supply. Consumption of trans fats, largely from PHOs, has been linked to increased levels of 'bad' (LDL) cholesterol, which can raise the risk of heart disease. The scientific consensus on the negative health effects of artificial trans fats led to the FDA's decision.

Allergen info

Partially hydrogenated oils are typically made from vegetable oils such as soybean, cottonseed, or corn oil. If derived from soy, it would contain a major allergen.
