Cholesterol in Plants?

Although we usually think of cholesterol as coming from animal products, plants contain very small amounts of cholesterol.1 The cholesterol content of plants is estimated to be hundreds to thousands times less than that of animals.2 These low levels of cholesterol mean that plants’ contribution to dietary cholesterol intake is extremely small. We were only able to find estimates of cholesterol amounts in plant oils but not in whole plant foods. Corn oil, for example, is reported to have 55 milligrams of cholesterol in a kilogram of oil.1 This works out to less than 1 milligram of cholesterol in a tablespoon of corn oil.  In contrast, one egg yolk has 184 milligrams of cholesterol.

     Plants contain much higher amounts of substances similar to cholesterol but with a slightly different structure called phytosterols or plant sterols. Manufacturers use plant sterols to make cholesterol which is sometimes used in pharmaceuticals.

     Vegans and lacto-ovo vegetarians have higher mean intakes of phytosterols than do nonvegetarians.3 This may be a benefit of a plant-based diet since higher consumption of plant sterols is associated with lower blood cholesterol and LDL (bad) cholesterol levels.4,5
