What oils are carcinogenic when heated

Q: What cooking oils are carcinogenic?

The Womans lifestyle magazine M2Woman recently ran the headline Science reveals that this commonly used kitchen staple is carcinogenic The accused kitchen staple is vegetable oil: canola, sunflower, and olive specifically. M2Woman claims these common cooking emollients are proven to be carcinogenic.

Q: Is olive oil carcinogenic if heated?

Myth: Olive oil produces carcinogens when its heated. Fact. Whats true is that when any cooking oil is heated to the point where it smokes (its smoke point) it breaks down and may produce potentially carcinogenic toxins. Different oils reach their smoke points at different temperatures.

Impact of consumption of repeatedly heated cooking oils on the incidence of various cancers- A critical review

Kumar Ganesan et al. Crit Rev Food Sci Nutr. 2019.

Abstract

Repeated heating of vegetable oils at high temperatures during cooking is a very common cooking practice. Repeatedly heated cooking oils (RCO) can generate varieties of compounds, including polycyclic aromatic hydrocarbons (PAH), some of which have been reported as carcinogenic. RCO is one of the commonly consumed cooking and frying medium. These RCO consumption and inhalation of cooking fumes can pose a serious health hazard. Taking into account exploratory study, the present review aims to provide the consumption of RCO and its fumes cause the high incidence of genotoxic, mutagenic, tumorogenic and various cancers. The information on RCO and its fumes were collected through a library database and electronic search (ScienceDirect, PubMed, and Google Scholar). Remarkable studies demonstrated that the health adverse effects of RCO and its cooking fumes have been often attributed to their detrimental properties and ease to genotoxic, mutagenic and carcinogenic activities. RCO and its cooking fumes were found to enhance the incidence of aberrant cells, including breaks, fragments, exchanges and multiple chromosomal damages and micronuclei in a dose-dependent manner. Furthermore, the large consumption of RCO has been associated with a number of malignancies, including lung, colorectal, breast, and prostate cancers. The present review provides additional insights into the polluting features of PAHs produced various cancers via cooking activities in indoor environments.

Keywords: Repeatedly heated vegetable oils; cancers; carcinogenicity; genotoxicity; mutagenicity; polycyclic aromatic hydrocarbons.

Which oils are toxic when heated?

These are oils like soybean, corn, canola, sunflower, and safflower. They're unstable fats – they're not bound together tightly at all. Because they are unstable, they can produce higher levels of free radicals when they're heated.
