From a dietary perspective, plant cells do not manufacture cholesterol, and it is not found in plant foods.   Some plant foods, such as avocado , flax seeds and peanuts , contain phytosterols , which compete with cholesterol for absorption in the intestines, reducing the absorption of both dietary and bile cholesterol.  However, a typical diet contributes on the order of grams of phytosterols, which is not enough to have a significant impact on blocking cholesterol absorption. Phytosterols intake can be supplemented through the use of phytosterol-containing functional foods or dietary supplements that are recognized as having potential to reduce levels of LDL -cholesterol.  Some supplemental guidelines have recommended doses of phytosterols in the – grams per day range (Health Canada, EFSA, ATP III, FDA). A recent meta-analysis demonstrating a 12% reduction in LDL-cholesterol at a mean dose of grams per day.  However, the benefits of a diet supplemented with phytosterols have been questioned. 
In 1975 a similar case was reported by Smith & Sugar. A six year old male underwent total removal of the left cerebral hemisphere because of intractable epileptic seizures. Conventional neurophysiological wisdom asserts that the left side of the cerebral cortex is responsible for our speech, mathematical reasoning and logical thought in general, and that the right cerebral hemisphere controls our intuitive, non-rational, non-verbal forms of thought. Yet this young man grew up to become a gifted student, proficient in verbal reasoning and language abilities, testing even into the gifted range of on standard intelligence tests.
