Minor health risks are associated with eating foods high in plant sterols, such as women having difficulty with the absorption of fat-soluble vitamins, according to Patient.co.uk. Sterols are also not recommended for pregnant women, lactating women or children under the age of 5, as they can reduce carotenoid levels.
Sitosterolemia, although a rare inherited disorder, can develop from a pregnant mother ingesting too many plant sterols and cholesterol, warns Patient.co.uk. This in turn can lead to early coronary heart disease in the child. Despite the minor health risks, sterols are known to be effective in reducing LDL cholesterol levels between 10 and 20 percent in individuals who consume 1 to 2 grams per day.
