Seven out of 10 of Australia’s top selling cookbooks related to health and wellbeing according to new research by Nielsen who examined 2017’s best-sellers.

Jamie Oliver was the most popular book of the year with his 5 Ingredients. The famed British chef also snared eighth spot with Super Food Family Classics. Oliver’s two books aside, Donna Hay’s Basics To Brilliance Kids was the only other title in the top 10 that didn’t have a health angle.

According to Nielsen, Aussies spent $14.8 million on cookbooks in the four weeks leading up to Christmas 2017.

It reported that star power still was the main driver of sales, although cookbooks with a health angle were steadily growing.

Intense competition for stocking space led to the steepest discount period for cookbooks by retailers in 2017 in lead up to Christmas in 2017. This competition keeps the average sale price at $29, a marginal increase over the yearly average of $27.90, the study noted.
