In addition to these conventional nutrients, avocados offer a wide range of phytonutrients that are related to their unusual fat quality. Included in this category are the phytosterols (beta-sitosterol, campesterol, and stigmasterol) as well as their polyhydroxylated alcohols. The major carotenoid found in the pulp of avocado is chrysanthemaxanthin. Other carotenoids in the pulp include neoxanthin, transneoxanthin, neochrome, and several forms of lutein. As mentioned earlier, avocado is also an especially rich source of monounsaturated fatty acids, and in particular, oleic acid, which accounts for over 60% of the total fat found in this food.
