How many syns are in an avocado?

Slimming World asks you to syn avocado on the plan, this is something which causes a lot of controversies as they are also described as healthy by many diets.

Avocados, compared to other fruits, are not low in calories and a medium avocado has around 250 calories and 23g of fat. That said these are often referred to as healthy fats.

They are a good source of dietary fibre, like many fruits and vegetables, and a lot of research suggests they help you to stay feeling full for longer.

Avocados are high in a variety of vitamins and minerals so are very much a superfood when it comes to a concentrated source of vitamins and minerals. This doesn’t stop Slimming World from asking you to syn them, unfortunately.

A whole avocado either fresh or pureed is around 14 syns. If instead, you prefer to work out the syns based on weight or are not having a full avocado then 100g of avocado is approximately 9.5 syns
