When fats (oils) are heated, their molecular structure is compromised, creating carcinogenic free radicals. Coconut oil is more stable to heat than other plant oils but it is still best when produced without heat.
Oils that are heated, when ingested, can contribute to cardiovascular disease and difficulty of the blood to efficiently transport oxygen due to arteriosclerosis.
Ingestion of heated oils can also contribute to acne and foul body odour.
Truly cold pressed oils will maintain their nutrient profile, their fats will remain uncorrupted, they taste amazing and they last long, as the oils have not been heated so are less likely to go rancid quickly.
