Well, according to Telman (which appears to be the resident CZ expert on oils) says that Macadamia Nut Oil is equal to or even more effective for LFing than Olive Oil. According to what I've read, the Oils best used for flushing are ones that are high in Monounsaturated fats and low in Saturated Fats, which Macadamia Oil seems to be. It has an even higher percentage of Mono fats and lower in Saturated fats than Olive-Oil
does. Below is how the 2 Oils compare:
Macadamia Nut Oil - 84% Monounsaturated, 4% Polyunsaturated, 12% Saturated
Olive Oil - 76% Monounsaturated, 10% Polyunsaturated, 14% Saturated
Almond Oil - 65% Monounsaturated, 25% Polyunsaturated, 10% Saturated
These seem to be the top 3 effective oils for flushing, starting with Maca down to Almond. When I do get my Nature's Kleen and start flushing, I will definitely keep you up to date =).
