If you don't already have a juicer, then I would certainly encourage you to buy one. No need to get the most expensive one on the market, just a plain and simple model will do. It's not something that you will use constantly, but when you don't have an appetite, it is a very handy devide to have in your home.
I usually buy organic carrots and juice about 7-8 to make approximately two medium glasses of delicious juice. Scrub the carrots with a vegetable brush but try not to peel them, as most of the nutrients lie in the outside of the vegetable. You should probably drink one glass first thing in the morning and another by lunchtime. Don't keep the juice refrigerated for several days, as it's best nutrients are there within a 12 hour period, so making only a small amount will suffice and will be most beneficial for the patient.
There will be many times while taking cancer treatments that your appetite will not be great, so drinking carrot juice offers you the benefit of receiving lots of vitamins and antioxidants when you need them most. The taste is actually not bad at all and you can also add an apple or other fruit to the mixture to sweeten the taste.
Our mothers always told us that carrots were good for your eyes....well it turns out that carrot juice offers many more benefits as well. I'm no medical expert so check it out with your doctor but there's numerous links online as well that will confirm what I've just written.
If you find a good website about this, just post the web address on the chat forum for others to research and I'll also post them below.
Good luck....and enjoy that nice cold glass of carrot juice on a hot summer's day!
