Charity Recipe E-Book

Claire worked with a team of dietitians to create a downloadable recipe e-book which is on sale to raise money for the Trussell Trust.

The Trussel Trust is a food poverty advocacy and aid group and provides families in need, with a 3-day emergency food parcel at one of their 1200 food bank centres across the UK so that they do not go hungry. 

The food parcels that the Trussell Trust distribute, contain non-perishable items that can be donated by the public at a range of places that include, supermarket collection points, churches, schools and businesses.

With the UK being one of the largest economies in the world, it seems unimaginable that food poverty would affect so many individuals in the population. According to a recent report (January 2019) by the Environmental Audit Committee, food insecurity and poverty levels are expected to keep increasing, reaching some of the worst levels in Europe, with children being most affected. As many as 1 in 5 children under 15 years of age are living in a home experiencing food insecurity; a shocking statistic.

We wanted to help.

So we have developed a charity recipe e-book, which is 54 pages long, full of family friendly meals, and is available to download for £3.99.  We are taking no money at all for this project, all proceeds go to the charity.

The idea behind the project is that people can help to support families in need whilst feeding their own.
