Here's a list for one shop that can get you to 30 over a week, combined with whatever's already in your cupboard. Screenshot it, cross things off.
Fresh
- Onions
- Garlic
- Carrots
- Red peppers
- Spinach or kale
- Mushrooms
- Bananas
- Apples
- Lemons
- A bunch of parsley or coriander

Nuts, seeds, dried fruit

Depending on how you count the mixed bags, that's comfortably over 30 different plants.
After the shop
When you get home, it's tempting to log everything you bought. Don't. The count is for what you eat, not what's in the cupboard. Log as you go. In Eating30, packaged things like the mixed beans and the seeded loaf can be scanned when you open them, so the label does the work.
Eating30 is an app for iPhone and Android that counts the different plants you eat each week, with 30 as the target. The core tracking is free. It's a habit tracker, not medical advice.
