Dirty Dozen and Clean 15

Dirty Dozen and Clean 15


Here I am in the fruit aisle staring at the blueberries. To buy or not to buy. Organic that is. £3.50 vs £2.00. Whilst an extra £1.50 may not seem like much, across an entire basket of food, this can add up for a family.

As you know, at Purearth we are huge proponents of all things pure and organic, however we also realise that an all-organic shop can be quite expensive.


Ways to get around this are:

  • Shop local. Some farms aren’t registered organic but ask about their farming practices and you will find many are.
  • Grow your own! In just one generation the majority of us have lost the know-how on how to grow our own food. It’s super easy to get a couple of planters or box gardensand try growing your own herbs, tomatoes, potatoes, lettuce and so much more.
  • Shop seasonally – buy what’s in season. It’s better for your wallet, and the environment. An organic pineapple or basket of peaches in the middle of winter is going to be expensive.
  • Freeze foods. Buy (or pick!) organic berries and fruits when they are in season and freeze them.

And when it comes to your shopping if you need to pick and choose, the EWG (Environmental Working Group (US) and PAN (Pesticide Action Network) put together a guide each year about the pesticides in produce, known as the ‘Dirty Dozen’for the reason that they contain the most pesticide residue when not grown organic and the ‘Clean 15’,which are the items with the least amount of pesticide residue when not grown organically. These change somewhat each year, but the majority of items stay the same.
