We hear so much debate about juice in the media and whether or not we should avoid or consume it as part of a healthy diet, so I hope to clear up the confusion surrounding the health benefits of juice once and for all.
In my view, commercially bottled juice really is little more than sugary water and you may as well pick up a confectionary bar, or can of soft drink when it comes to the sugar content, especially if it's made from fruit juice concentrate, or contains added cane sugar as some brands do. Let me bring this into perspective, the average 250ml serve of bottled fruit juice contains between 26 - 42gm of sugar / 6 and a half to 10 and a half teaspoons! (depending on the fruit flavour you opt for). A standard 375ml can of coke contains approximately 39gms of sugar or nearly 10 teaspoons. Whilst it's true fresh juice may contain plenty of live enzymes, vitamins, minerals and antioxidants, the amount of sugar that accompanies the nutrients and the removal of the fibre, negates the nutritional value in my opinion. Many people don't realise that bottled juice has also been pasteurized to kill off any bacteria and enable it to be stored without refrigeration before opening. The process of pasteurization also kills off any nutritional value, so you really are just left with pure sugar in the form of fructose and glucose.
The manufacturing process to convert a piece of whole fruit in to juice.
The juice factory takes the whole fruit, extracts the fibre - bang up goes the GI factor right there ( insulin producing factor - not good if we are trying to keep fat and inflammation to a minimum), then boils the billyo out of the juice - a process better known as pasteurisation - great for killing any nasty bacteria and enabling the juice to sit unrefrigerated on the supermarket shelf. But this heating process is also effective in knocking off precious vitamins and minerals in the process - so really what reason is there for drinking the stuff if it contains no fibre, no nutritional value and is on par with a can of coke in the sugar stakes per 100ml?
There are some juice brands that require refrigeration at all times because they contain no preservatives (tick), however this does not mean they escape being heated / pasteurised, they're just removed from the heat and chilled more quickly. A little healthier than their friends on the supermarket shelf perhaps, but not much better in the nutrient stakes and no fruit juice can hide behind the fact that they are high in sugar.
So whilst some brands of bottled juice may be a preferable choice to say soft drink and bottled juice with added sugar or those that do not require refrigeration before opening, they cannot be seen as a healthy alternative for eating a whole piece of fresh fruit when it comes to nutritional value and the impact on blood sugar levels.
The other issue surrounding bottled juice stems from the serving size. Many brands of bottled juice are just far too big, thus delivering a mega dose of fructose - the naturally occurring sugar in fruit that's copping a bad rap from the health police right now - and rightly so considering fructose is the most fattening form of sugar we can consume. Many processed foods are laden with the stuff thanks to being a cheap sweetener as well the fact it keeps you coming back for more.
The Low Down On Fresh Fruit Juice
So what's the drill on freshly squeezed fruit juice? One of the biggest misconceptions surrounding fresh fruit juice is that it is a health food. Certain mega franchise juice bars are making a killing from promoting fresh juice this way, but the truth of the matter, is that whilst the fruit may be juiced in front of you with no added sugar, concentrates or preservatives, you usually end up consuming the juice of 5 - 6 pieces of fruit or more - up to 5 times more than the recommended 1 - 2 pieces of whole fruit per day.
Take your standard Mars Bar which contains 38.4gms of sugar per serve, around the same amount of carbohydrate as a 250ml serve of fresh pineapple juice. Sure the fresh pineapple juice contains nutrients such as bromelain - an enzyme renowned for its anti inflammatory action, however you should also be mindful of the pro-inflammatory effects associated with excess insulin production - that results from consuming too many fast burning carbohydrates. It is the fast burning or 'high GI' carbohydrates that end up being the most fattening, as well as lead to the development of conditions such as obesity, diabetes, stroke and heart attack.
So whilst fresh fruit juice may contain vitamins and minerals that confectionary or soft drink lacks, we really should be limiting our juice intake to a small serve (200 - 250ml) of freshly squeezed fruit juice, consumed as an occasional treat - say once a fortnight or less - especially if you are trying to lose fat. Better still, try to choose low to medium GI - (glyceamic index - a measurement of the insulin producing factor for various foods), fruits in your fresh fruit juice combo.
But in all honesty the only healthy way to consume juice and not add extra padding to your hips and thighs, is to juice fresh organic vegetables. 'Vegetables!' I hear you cry...... well all I can say is try it! You may be pleasantly surprised, not to mention your skin will start to glow and your hair glisten. Vegetable juicing has long be renowned for its ability, not only to provide your body with a giant wack of vitamins and minerals, but as one of the most effective ways to alkalise your body overall. Put simply, if our body's pH is more alkaline than acidic then there will be less room for inflammation and ensuing disease or illness.
To assist with easing your taste buds in to the flavour of fresh vegetable juice, I suggest adding one apple (organic of course) for a little sweetness. But as you ween yourself off a high sugar diet, your pallet will begin to change and you will no longer desire such sweet tasting food. In fact you may even notice that your food begins takes on a whole new flavour ( for the better), as your system begins to alkalise and recalibrate so to speak.
Best fruits and vegetables I recommend for juicing are:
Essentially any green vegetable that will give you a decent amount of juice. Vegetables are also HIGHLY alkalising and great to assist in detoxing and stimulating your bowel function:
Spinach or silver beet
Lemons or limes - these are LOW in fructose and add a lovely tang to your juice and are naturally alkalising to your system as well as great for stimulating liver detoxification and bile production for fat emulsification (digestion)
Aloe vera - has a soothing, anti inflammatory effect on the lining of the intestine - great for those suffering IBS - irritable bowel syndrome - add a slurp of bottled aloe if you can't source it fresh.
Ginger - contains natural anti-flammatory properties as well as being grounding to the nervous system
Tumeric - an even more powerful anti-flammatory agent, as well as a whole host of healing properties
Lettuce or bok choy
Of course you don't have to include all these vegetables in your fresh juice, but including at least 4 varieties is a good start.
My personal recommended combination:
2 sticks of celery
juice of a lemon
1/2 fresh grapefruit
1 - 2 spinach or silver beet leaves
Small knob of fresh ginger and or turmeric
If you can, I strongly recommend juicing organic green vegetables where possible because of the contamination with chemical pesticides and herbicides, especially varieties with a large surface area, such as spinach / silverbeet.
I recommend avoiding these vegetables if you have, or suspect you may suffer from an underactive thyroid as these belong to the cruciferous family and can block the absorption of minerals such as iodine, which is required by the thyroid gland to produce thyroid hormones.
Be sure to drink your freshly made juice immediately if you using a traditional (centrifugal) juicer, as it will quickly oxidise from free radical damage and avoid making it in bulk to store in the refrigerator for later consumption.
I also recommend washing down your fresh vege juice with a large glass of filtered water as vegetable juice combinations are quite rich and may irritate your bowel if you drink too much in one hit.
So just to recap .... when it comes to juice - my top recommendation is fresh organic vegetable juice with no more than 1 apple.
Fresh fruit juice is fine as an occasional treat versus a daily staple. Try to limit fruit juice to a 200ml serve, made from low to medium GI fruits if possible.
