You may want to consider to invest in a good juicer, such as these:
http://www.championjuicer.com.au/ there are many on the market these days.
Not the ones that spin real fast, a slow juicer that is gear driven. They extract maximum nutirants from the fruit/vegetables you juice. Try and source organic vegetable to juice. Carrot juice is excellent and full of beta carotene, you should drink carrot juice every day. Also juicing greens is excellent.
Barley green is probably something you should also drink it is a great blood cleanser amongst many other things:

Unfortunalty most doctors wont go into the benefits of these simple natural approachs because they are mostly controlled by drug companies looking for profit. Drug companies make money from sick people not from healthy people. Look at all the meds you are on, and imagine all the other people on things and think how much the drug companies are making from that.
Try and eat as much raw food as possible, and cut back on cooked oils. And if can, eliminate sugar all together. Try to cut coffee right back as well, maybe drink green tea or other herbal teas that contains antioxidants.
Also herbalfibre blend is beneficial to anyone, but especially if your health isn't 100%, healthy bowels is fundamental for good health:

Drink lots of water, and be sure to use a good filter if drinking from the tap to remove as much chlorine and heavy metals as you can. Unfortunatly its quite hard to remove fluoride but can be done if you invest in a good filter system but they are expensive.
ASPARATME: Avoid at all costs its deadly. It is in chewing gums, diet drinks, artificial sweetners and many other things. If you see E951 or other numbers in the 900's on the ingrediants of a product don't consume it.
MSG: Another additive to be avoided at all costs. If you see 621, 631, 635 on the ingrediants of a product do not consume. Its also called a 'flavour enhancer'.
I hope this is helpful, it may seem like a lot to take in but its really quite simple when you compare it to what doctors will prescribe you from the drug companies who have very little interest in your health. I think this sort of thing really requires a major shift in thinking. Ultimatly you need to research the alternatives and your options and decide for yourself.
