The Dirty Dozen & Clean Fifteen 2026
What to buy organic (and what not to panic about)
Every year a list comes out that causes a little ripple in the nutrition world.
The “Dirty Dozen”.
This is the list of fruit and vegetables found to contain the highest levels of pesticide residues when tested. It does not mean these foods are dangerous or poisonous… but it does mean they are the produce items most likely to be heavily sprayed during farming.
So if you are going to prioritise organic produce, these are usually the foods worth focusing on first.
The Dirty Dozen for 2026
This year’s list includes:
• Strawberries
• Spinach
• Kale, collard & mustard greens
• Peaches
• Pears
• Apples
• Grapes
• Blueberries
• Cherries
• Nectarines
• Blackberries
• Potatoes
Most of these foods have thin skins or soft flesh, meaning pesticide residues are more likely to remain on the food we actually eat.
Berries are particularly well known for this.
Now before everyone starts panicking in the supermarket…
Let’s keep things sensible and balanced.
Eating fruit and vegetables – organic or not – is still FAR healthier than avoiding them altogether.
But if you have the choice, buying these organic where possible is a sensible upgrade for overall health.
The Clean Fifteen
The good news is there are also foods consistently found to contain very low pesticide residues.
These tend to have thick skins, protective outer layers or peels which we remove before eating.
The Clean Fifteen include:
• Avocados
• Sweetcorn
• Pineapple
• Onions
• Papaya
• Frozen sweet peas
• Asparagus
• Honeydew melon
• Kiwi
• Cabbage
• Mushrooms
• Mangoes
• Sweet potatoes
• Watermelon
• Carrots
So if your budget is tight, these are generally the foods where buying organic is less important.
Why this matters for the liver
Your liver is your body’s main detoxification organ.
Every single day it works behind the scenes processing:
• chemicals
• medications
• alcohol
• food additives
• pollution
• hormone waste
• pesticide residues
The body is incredibly clever and designed to cope with a lot. But modern life creates a huge toxic load.
And when people are already struggling with:
• IBS
• bloating
• fatigue
• inflammation
• hormonal issues
• headaches
• sluggish digestion
…we often need to reduce the overall burden on the body wherever possible.
Your gut and liver work very closely together.
When the liver is overloaded, digestion often suffers too.
What about the immune system?
Your immune system is heavily influenced by your diet and gut health.
In fact, a huge percentage of the immune system is connected to the gut.
When the body is constantly dealing with inflammatory foods, stress, ultra processed foods, chemicals and environmental toxins, it creates more work for the immune system.
Again – this is NOT about creating fear.
It is about reducing unnecessary stress on the body where possible.
Small changes add up.
My personal rule when shopping
I keep this really simple. If the food has a thin skin and you eat the outside… Try to buy organic.
Examples:
• berries
• grapes
• apples
• leafy greens
If the food has a thick peel or skin you remove…
Examples:
• avocados
• melons
• onions
• pineapple
Simple. Realistic. Affordable.
Because healthy eating should not feel stressful!
Support your body naturally
One of the best ways to support the liver and digestive system naturally is through simple nutrient-rich meals.
Fresh juices can be brilliant for increasing hydration, minerals and antioxidants. A favourite of mine, and one I use regularly is this recipe:
Warming homemade soups are also fantastic for digestion and immune support – particularly if your gut feels irritated or inflamed. My clients top favourite soup recipe is this one:
This is also why I encourage clients to improve the quality of their kitchen tools and cooking methods where possible.
Good food deserves proper preparation. I simple couldn’t live without these awesome kitchen gadgets – and I use them weekly (a lot of them daily).
Most people think they eat well…
This is something I see all the time.
People genuinely believe they are eating “pretty healthy”…
But when we analyse things properly, we often uncover:
• low fibre intake
• lack of plant diversity
• hidden processed foods
• nutrient deficiencies
• poor hydration
• inflammatory eating habits
• gut triggers they never noticed before

It is designed to help you understand:
• what your diet is doing to your body
