Is coffe good? What about fruit and veggie juice from a slow juicer??

Coffee is okay, in moderation.
Instead of fruit and vegetable juice, try eating them whole, as in this way, the pulp in the fibre will not go waste.
You will able to consume more fibre if you eat the whole fruit / vegetable.
Drinking fruit juice is equal to consuming concentrated sugary drink, as the juice will just contain concentrated fruit sugar, without the fibre which is present in the fruit pulp which gets wasted when you juice a fruit.
