Busy so I'm skipping articles. Busy life demands juicers but too many people see it as kind of gastronomic confession . I have friends who would spend 6 months on piss and eating crap and then go off to Thailand for one week of fasting and enemas. Now the latter is obviously dodgy (especially people who use them for administering hallucinogenic cactii in NZ) but whole purging concept is wrong and potentially dangerous. I actually think it's based on faulty metaphor that body is something that can be flushed out. The damage is already done and what you've eaten or drunk has already become part of you.
More often better, even if it's just Sunday recuperative. The major factor in irregular juicer use is that most are a pain to use, requiring mucho chopping in state or at time of day when knives should be given rest. Spend little more and get one with feed chute that can fit whole regular sized apple, I've got Breville one and it rocks.
Juice mixes are fairly random, remember to peel citrus fruits and kiwi fruits, and keep some celery chopped up and ready to go. Ginger is great for adding zing and taking away any muddy flavours. Adding something juicy like celery at end helps rinse out pulp for cleaning and the pulp can go in garden.
Yesterday, for example, was ginger, beetroot, celery, carrot, apple, and kiwi fruit . Took a few minutes. Nice, and with regular cycle of smoothies, and freshly squeezed OJ, keeps me hell away from Thai health spas.
