Greetings Greatful2012! Welcome to the diet and nutrition Healthboards!
In my opinion the fruit meal should be kept separate from the vegetable meal and I think they taste better in separate meals usually anyway with only a few minor exceptions. I think it is o.k. for lemon juice to be put on greens or salads with other seasonings. Most of the time, however, inside the body vegetables mixed with fruit create a sort of war in the stomach and does not feel quite as good in my opinion as meals with the fruits and vegetables kept separated.
As far as blending goes for a real meal I would not to do that all the time unless there are no teeth or very poor teeth. If teeth implants are needed and can be put in they should be put in. After awhile one really wants good solid food. Two or three simple dishes in any one meal are sufficient in my opinion. I think the digestion might actually be better possibly if it is not blended just because the saliva is to have an important action on the food. When food is blended there is a tendency in some people at least to swallow it earlier than it would have been if it had been chewed and therefore there would be less time for the food to be in contact with the important digestive fluid in the mouth.
Some foods, however, can be made with the blender such as mayonnaise without vinegar and additives in a blender and then it would be healthier than the real mayonnaise. Also some wonderful nut milks may be made in the blender. If the real milk had dangerous bacteria, virus or prion in it then of course the nut milk would be healthier.
If vegetable or fruit juices are used between meals they need time in the mouth before swallowing with mouth motions as if swallowing to help stimulate the production of saliva with it.
Some people do develop diabetes if a lot of sweet fruit juices are used. ( some of them tend to use desserts also which may also contribute to diabetes. ) That is why when juices are needed or desired I would encourage the use of vegetable juices more and perhaps an eight ounce glass of orange juice daily if desired but not much more of sweet juice.
Juicing has helped some people get stronger after surgery, chemotherapy and a bout of cancer. Some people have gotten well with juicing alone. Others have gone to their grave with juice alone. Perhaps they did not follow all of the rules to have a healthy body. Different types of vegetable juice need to be used over the period of a week. Of course everyone makes their own health care decisions and if a professional is desired a dietician could be seen. Peace, sjb
