Is Organic food Worth the Cost? How to Choose Organic Wisely
September is Organic September in the UK, a month-long campaign that encourages us to think more carefully about organic food, farming and sustainable living.
It is also a good time to ask a very real and practical question: Is organic food worth the cost?
Although many of us understand the potential benefits of choosing organic, the cost can be a genuine concern. Food prices have risen, family budgets are stretched, and organic products can be noticeably more expensive than non-organic alternatives.
So where do you start?
Do you need to buy everything organic? And if you can’t, which foods are worth prioritising?
That is what I want to explore in this article.
No time to read? You can watch my video on whether organic food is worth the cost below.
What exactly is organic food?

Organic food is grown, produced, stored and transported without the routine use of man-made chemicals, fertilisers, pesticides, herbicides, artificial colours or preservatives.
Organic farming also avoids growth stimulants such as hormones in livestock, certain additives to livestock feed, and genetically modified ingredients in foods fed to livestock.
DEFRA describes organic agriculture as a systems approach to production that works towards environmentally, socially and economically sustainable production.
So choosing organic is not only about the potential health benefis of organic food to us as individuals. It also extends to the environment, climate change, soil health and animal welfare.
That is one of the reasons so many people feel drawn to organic food. Organic food can also play a role in healthy ageing.
But I also understand that price matters.
Why Organic May Help Reduce Your Toxic Burden

One of the main reasons people choose organic is to help reduce their exposure to pesticide residues and unnecessary chemicals.
We live in a world where our chemical burden is much greater than it once was. It is not just about food. We are exposed to chemicals through the air we breathe, the water we drink, skincare, cleaning products, household materials and the wider environment.
Not all of these chemicals are avoidable, and it would be impossible to live in a perfectly toxin-free bubble.
A UK Parliament report contained staggering information and worrying statistics. Chemical production has increased 50-fold since 1950. It is estimated that there have been 140,000 new chemicals created in this timeframe.
Some fruits have 75% higher pesticide levels compared to organic ones. Some vegetables have 32% higher pesticide levels.
Therefore, any action we can take to decrease that burden is beneficial.
Our liver is the organ of detoxification. It works hard to neutralise toxins so they can be eliminated safely from the body. All these additional chemicals require detoxification, placing more demand on the liver and our other eliminatory organs, including the bowels, lungs, kidneys and skin.
When the body is under a higher toxic load, some people may notice symptoms such as skin irritation, spots, rashes, headaches, mood changes, fatigue or digestive disruption.
Chemicals can also affect the gut, irritating the intestinal barrier, upsetting the delicate microbiome and potentially contributing to food sensitivities or histamine-type responses.
This is why organic food can form one useful part of a wider healthy lifestyle.
It is not about being perfect. It is about reducing the burden where you can.
Is Organic Food More Nutritious?

Research has shown an increased level of antioxidants in fruit and vegetables by as much as 60%. This is equivalent to 2 pieces of fruit or vegetables each day.
Antioxidants (such as vitamin C) protect cells from damage caused by unstable molecules known as free radicals. Free radicals can increase the risk of DNA damage, inflammation and other health conditions, even cancer risk.
Another important consideration is soil quality.
Soils have become depleted in key minerals due to heavy farming practices. Organic practices such as crop rotation, companion planting and the use of natural manures aim to support the soil and allow minerals to return to it.
Mineral levels in non-organic vegetables have declined significantly between 1930 and 1980: calcium levels by 46%, copper by 76%, sodium by 49%, iron by 27% and magnesium by 24%.
Our diets today can rarely meet the nutritional status of our parents.
I’ve also written more about why bright coloured fruit and vegetables are so important for healthy ageing and antioxidant support.
What About Organic Milk, Dairy and Meat?

Organic milk has been shown to contain higher levels of Omega-3 essential fatty acids and up to 60% higher levels of the key fats EPA and DHA. These essential fats are anti-inflammatory to the body, cardioprotective and support brain health. One reason is due to cows being mostly grass-fed rather than relying on grains.
If you’d like to understand more about why these fats matter, I’ve explained this in my article on healthy fats and omega-3.
Organic dairy also has higher levels of iron. It was found to have lower levels of iodine, an important mineral for the thyroid gland, and organic feed is now fortified with iodine.
Organic meat also has up to 47% higher levels of Omega-3 fats and lower levels of saturated fats. So the fat ratio is more desirable.
Where to start?
If dairy is something you or your family use regularly, organic milk can be a good place to start. With meat, you do not need to buy organic every time. Instead, you might choose organic for an occasional meal or special roast, or simply buy free-range, grass-fed and the best quality you can afford.
Heavy Metals and Organic Crops

Cadmium is a highly toxic metal to humans.
Organic crops were found to have 50% less cadmium than non-organic.
This matters because cadmium can displace zinc, potentially contributing to a nutrient deficiency. Zinc is essential for immunity, skin health, prostate health and fertility.
Again, this does not mean you must buy everything organic.
But it does give us another reason to think carefully about where organic may be worth prioritising.
I understand the benefits, but I’m concerned about the cost?

This is the most realistic question for many people.
Organic food does cost more, and it is not always possible or practical to buy everything organic.
So my advice is simple: do not aim for perfection.
I recommend that your starting point for buying organic should be to review the Environmental Working Group’s annual review of the cleanest and dirtiest foods, known as “The Clean 15 and the Dirty Dozen”.
This looks at chemical residues on the fruit and vegetables after harvesting.
This is a US-based guide, so it is not a perfect match for UK food testing, but it is still a useful tool for thinking about which conventionally grown foods tend to have higher pesticide residues and which tend to be lower.
Focus your attention and choose organic for the dirtiest foods (the dirty dozen) and buy non-organic for the cleanest foods (the clean fifteen).
The Dirty Dozen
- Spinach
- Kale, collard and mustard greens
- Strawberries
- Grapes
- Nectarines
- Peaches
- Cherries
- Apples
- Blackberries
- Pears
- Potatoes
- Blueberries
The Clean 15
- Pineapple
- Sweet corn (fresh and frozen)
- Avocados
- Papaya
- Onions
- Sweet peas (frozen)
- Asparagus
- Cabbage
- Cauliflower
- Watermelon
- Mangoes
- Bananas
- Carrots
- Mushrooms
- Kiwi
The idea is simple.
Where possible, choose organic for the Dirty Dozen and feel more comfortable buying non-organic from the Clean Fifteen.
This allows you to be more strategic, rather than feeling you have to buy everything organic.
Simple Ways to Choose Organic Without Overspending
You do not need to overhaul your whole food shop overnight.
You could start by choosing one or two organic swaps that feel manageable.
For example:
- organic berries if your family eats them regularly
- organic apples if they are a daily snack
- organic leafy greens if you use spinach or kale often
- organic milk if dairy is a big part of your diet
- organic meat occasionally, but choosing better quality and smaller portions
- organic eggs if they fit your budget
- organic herbs if you use them often
You can also reduce your toxic burden by thoroughly washing fruit and vegetables, peeling where appropriate, choosing seasonal produce, cooking more from scratch and reducing ultra-processed foods.
Remember, the goal is not to feel guilty.
The goal is to make better choices where you can.
Grow your own

So many people, including myself, have started to develop a vegetable patch and experiment with growing their own food.
You don’t have to have an extensive garden. A small plot, using pots on a patio or even herbs on a window sill all count towards a positive change.
There is something very rewarding about growing food yourself. It helps you connect with the seasons, appreciate food more and often encourages you to eat more vegetables. If you’d like to read more about this, I’ve written about the health benefits of gardening.
Could you join up with neighbours or start a scheme to grow different crops that you can share?
Choosing a more organic lifestyle, with some organic foods, should be part and parcel of a healthier way of life.
Final Thought
So, is organic food worth the cost?
In some cases, yes.
But that does not mean everything you buy has to be organic.
For me, the best approach is to be informed and realistic. Choose organic where it may make the biggest difference, especially with foods known to have higher pesticide residues, and do not worry about trying to be perfect.
Use the Dirty Dozen and Clean Fifteen as a guide.
Prioritise good quality real food. Grow a little of your own if you can.
And remember that choosing a more organic lifestyle, even with some organic foods, can be part and parcel of a healthier way of life.
