““the absorption of most nutrients is dependent on or influenced by the presence of other nutrients. Nutrient enhancers can keep a nutrient soluble or protect it from nutrient inhibitors. For example, beta-carotene, lutein, and lycopene are fat soluble, which means they require fat for optimal assimilation, so adding an avocado to a green salad (increasing its fat content by 47 percent) can help you absorb seven times more lutein and eighteen times more beta-carotene.””
