In the book "Fit For Life" by Harvey and Marilyn Diamond, stated inter-alia:

The consumption of exclusively fruit and fruit juice in the morning is at the very heart of Fit For Life.
The second consideration pertain to the amount of time that should elapse between eating foods other than fruit and then eating fruit.  As long as your stomach is empty, you can eat all the fruit you wish over as long a period as you wish, so long as twenty to thirty minutes elapse before eating anything else. This will allow the time necessary for the fruit or juice to leave your stomach.  Juice and some fruits take less time, but twenty to thirty minutes is a good standard to use.  Bananas, dates and dried fruit need about forty-five minutes to one hour.

I am following the above good advice and I find it helps me.  Yes, I will do anything to improve my health.
Happiness is to be healthy.  Health is wealth is certainly something to hold up to.
