A big chunk of a day's sugar in one serving.
Prune Juice carries roughly 15 g of sugar per 100 g, which works out to about 14.8 g per 100 g. That places it in the 'high' band for a typical serving.
Because this sugar occurs naturally in the food itself, it typically comes packaged with fibre, water, or other nutrients that slow how fast it hits your bloodstream — unlike the same amount of sugar added to a processed product.
