Partially Hydrogenated Oil

ingredientAdditivesAlso known as: PHO

Summary

Partially hydrogenated oil (PHO) is a type of vegetable oil that has been chemically altered to be solid at room temperature, increasing its shelf life and stability [Source X]. However, PHOs are a major source of artificial trans fats, which have been linked to numerous health concerns [Source X]. Due to these health risks, many countries have banned or restricted the use of PHOs in food products [Source X].

What it is

Partially hydrogenated oil is created through a process called partial hydrogenation, where hydrogen is added to liquid vegetable oils to solidify them. This process changes the oil's molecular structure, creating trans fats [Source X].

Common uses

  • Used in processed foods to improve texture and shelf life [Source X]

  • Formerly common in margarine, shortening, baked goods, and fried foods [Source X]

Public Perception

Anxiety level

High, due to the well-publicized health risks associated with trans fats [Source X]

Cultural claims

  • Associated with unhealthy processed foods [Source X]

  • Perceived negatively due to links with trans fats and health risks [Source X]

Source sentiment

Largely negative due to health concerns and regulatory actions against its use [Source X]

History

Timeline

1911

Procter & Gamble introduces Crisco, a partially hydrogenated cottonseed oil, as a cheaper alternative to animal fats [Source X]

1990

Increased awareness and research highlight the negative health effects of trans fats [Source X]

2015

The FDA determines that PHOs are no longer Generally Recognized as Safe (GRAS) in human food [Source X]

2018

PHOs are banned in the United States, with some exceptions [Source X]

Origin

To create a solid fat from liquid oils for use in food products, enhancing shelf life and stability [Source X]

Science

Key findings

  • PHOs are a primary source of artificial trans fats in processed foods [Source X]

  • Consumption of trans fats increases the risk of heart disease, stroke, and type 2 diabetes [Source X]

  • Trans fats have no known health benefits and are considered detrimental to cardiovascular health [Source X]

Studies

Association of Dietary, Circulating, and Adipose Tissue Biomarkers of Fatty Acids With Coronary Heart Disease: A Systematic Review and Meta-analysis

This study found a significant association between trans fat intake and an increased risk of coronary heart disease [Source X]

Safety status

Unsafe for consumption due to the high levels of trans fats [Source X]

Nuance

While the complete ban on PHOs has reduced trans fat levels in many foods, some products may still contain trace amounts. Always check food labels for trans fat content [Source X].

Alternatives

Unsaturated Oils (e.g., olive oil, canola oil)

Healthier fats that do not contain trans fats and offer beneficial fatty acids [Source X]

Where to find: Available in most grocery stores [Source X]

Butter

A natural fat source that, while high in saturated fat, does not contain trans fats [Source X]

Where to find: Dairy section of grocery stores [Source X]

Coconut Oil

Solid at room temperature and can be used in some baking applications, though it is high in saturated fat [Source X]

Where to find: Health food stores and some grocery stores [Source X]

Avoidance tips

  • Read food labels carefully to check for 'partially hydrogenated oil' or 'trans fat' [Source X]

  • Choose fresh, whole foods over processed items [Source X]

  • Be cautious of baked goods, fried foods, and snacks, as they are common sources of trans fats [Source X]
