I have heard that eating Olive Oil will interfere with absorption of vitamins and minerals
Fat soluble vitamins A,D, E and K are found in fatty foods. Some seed and fish oils are particularly high in vitamins. (See Nutrition for information about vitamins in olive oil.) If olive oil were to "soak up" fat soluble vitamins in the stomach from a pill or other foods, the vitamins would still end up in the body; the oil is absorbed into the gut to the blood stream and from there to all of the cells.
This misconception may have come from the use of Mineral oil as a laxative. Mineral oil cannot be absorbed by the body so goes completely through the GI tract, keeping the stool soft on the way out. If you were to take a fish oil capsule with your mineral oil, the fat soluble vitamins would be absorbed and trapped by the mineral oil and excreted.
