MY TEN-A-DAY SHOPPING LIST I shopped on tesco.com because I’m familiar with the website. To work out how much I got for my money, I divided the weight of each item by 80g – NHS-recommended portion size for fresh fruit and veg. For dried fruit, like sultanas, it’s 30g; for juice, one portion is 150ml. For peeling fruit, I looked up the weight without peel; for tinned veg, I used the drained weight. Then I divided the price by the number of portions to give the cost per portion.
