The science behind organic juicing

Juicing gained enormous popularity over the last fifteen years, and has lately been losing some of it to blending — blending is faster, easier, and leaves no pulp behind. Search for studies comparing the two and you will find them contradicting each other freely, which leaves most people at the mercy of whoever is selling the machine.

You can just as easily find research arguing that eating the fruit and vegetables outright beats both. All of it exists to promote somebody’s product. There is no clean winner. What there is, is a right answer for a specific purpose — and in a healing protocol the purpose is very specific indeed.

Juice or smoothie

The difference is fibre. A smoothie keeps it; a pressed juice removes it.

That sounds like a loss, and in an ordinary diet it usually is. In a healing context it is the entire point. Without fibre, juice is absorbed almost immediately — close to an intravenous infusion in how quickly the nutrients arrive and how little the digestive system has to do to get them. For someone whose digestion is compromised, whose appetite has collapsed, or who is trying to take in a very large quantity of nutrients across a day, that difference decides whether the protocol works at all.

This is why juicing dominates in healing diets and why the Z4 nutrition regime is built on it. Ten or so pressed juices across a day is a volume of vegetables nobody could chew.

Why organic is not optional here

In an ordinary diet, organic is a preference. In a juicing protocol it is a requirement, for a simple arithmetic reason: juicing concentrates. Pressing a kilogram of carrots into a glass concentrates whatever was on and in those carrots — the nutrients you want, and the residues you do not, at the same ratio.

Multiply that by ten glasses a day for seven days and the difference between organic and conventional produce stops being philosophical.

What goes into the glass

The juices are separated into three groups, and the order matters as much as the contents:

• Citrus — first thing, on an empty stomach, to wake the system up
• Fruit — through the morning, for immediately available energy
• Green — the workhorse, spread across the rest of the day

The exact quantities and the sequence are set individually by the therapist. Someone recovering from chemotherapy and someone dealing with burnout will drink very different days, even in the same group, in the same week.

Doing it at home

Most guests want to continue afterwards, and should. Three things make the difference between continuing and quietly stopping in week three:

1. A slow (masticating) juicer, not a centrifugal one. Less heat, less oxidation, more yield. The cheap fast one is why most people give up — the cleaning is worse and the juice is poorer.
2. Drink it immediately. Fresh juice starts degrading within minutes. Storing it defeats the purpose.
3. Be realistic about scale. A full protocol is not a home routine. Two or three juices a day, sustained for a year, will do more for you than ten a day abandoned in a fortnight.

If you want the full regime with the rest of the protocol around it, that is what the Z4 Protocol week is for.
