I don't buy it in packet form but do eat a lot of fresh fruit which I understand is equally bad. We have had a massive crop of soft fruit this year and I have made a pig of myself on the raspberries, figs and earlier on, blackcurrants! Am I asking for trouble as I do have arthritis in one knee and am anxious not to aggravate the situation. Since I've been walking regularly the arthritis hasn't given me pain, but I'm very conscious that it is there waiting to flare up at some provocation. Does anyone know the full story ?
