Calculating Fruit Needed For Family

How much fruit do I need for family of 6

So having made myself a little chart with the yield of the fruit on it, I now need to work out how much fruit I will need. Sat down with notepad and pen i started to calculate our fruit intake. That sound a very simple task but, one child eats only bananas, strawberries and any fruit jam and jelly possible, one doesn't touch jam or jelly and another eats any fruit going.The easiest way I discovered to work it out is to go through my shopping lists and online purchases.

Fruit Crumble- 1 a week

Jam- we use on average 1 jar a week 

Fruit Pie- 1 a week

Fruit bowl

Jam- 52 jars would be needed in total or maybe a few more if I have left over fruit to preserve. Some jams use 1/2 lb and some use 1 lb of fruit, so for arguments sake I took an average of 3/4 lb for each jar. So I would need to produce 39 lb of fruit for a years supply of fruit.

Pies and Crumbles- I estimate to produce 2 pies/crumbles a week I will need about 100 lbs of fruit for the whole year. This may sound very daunting but if you consider most of this will be fruit hard fruits from trees then it doesn't sound too bad. 

Fruit bowl- obviously I'm not going to be able to grow my bananas, lemons and oranges in the uk, but everything else I can get going. I estimate we use between 2-3 lbs in the fruit bowl a week, and the occasional melon.  Maybe as I get things rolling I can look into trying to grow my own lemons and oranges. So a total of of about 120lbs of fruit will be needed, its all starting to mount up.

If I add up all the fruit needed for a year it is a grand total of 259 lb a year !!!!! is it possible?
