How Many Syns in Prunes?
By Jenny Updated
Prunes can qualify as a Healthy Extra on Slimming World, meaning you can have a specific measured portion without using any syns as part of your daily allowances. Fresh prunes are free. Dried prunes can count as part of your HEB fruit allowance. Tinned in juice add syns due to natural sugar concentration. Most fresh fruit is a free food on Slimming World, and many varieties are also Speed Foods — the subset of free foods actively associated with faster weight loss. Dried fruit and fruit juices are the exceptions: the drying and pressing process concentrates sugar significantly, removing most of the water and fibre that makes fresh fruit filling and syn-free. Switching to the fresh version of a fruit you normally eat dried is one of the easiest syn-saving changes on plan.
