Simple everyday changes to reduce chemical exposure, improve nutrition and support healthy ageing.
In brief: You cannot avoid every environmental chemical, but simple everyday swaps can reduce unnecessary exposure. Choose smaller, low-mercury fish, rotate whole grains, buy organic selectively for higher-residue produce, cook with olive oil, drink filtered water from glass or stainless steel, and stop heating food in plastic. Alongside that, good nutrition, exercise and healthy circulation support the liver, kidneys, gut and antioxidant systems that process what remains.
Are everyday foods and household products exposing us to more chemicals than we realise?
Every day, we come into contact with substances that weren’t part of our grandparents’ daily lives to the same extent.
Pesticides on food, microplastics in drinking water, chemicals in food packaging, heavy metals in certain fish, synthetic fragrances and pollutants in our homes are all potential sources of exposure.
At the same time, modern food production, processing, storage and changes in agricultural practices can influence the nutritional quality of our food.
Some historical food composition studies have reported declines in selected minerals and vitamins in particular crops. However, these findings vary considerably between nutrients and foods, and do not mean that all modern produce is less nutritious.
The challenge is that we cannot completely avoid environmental contaminants. But we can reduce unnecessary exposure through simple everyday choices.
You don’t need to live on an organic farm, grow all your vegetables or spend a fortune on specialised products. Often, the biggest improvements come from replacing something you already eat or use with a better alternative.
Here is my practical guide to reducing everyday chemical exposure while supporting your body’s natural protective systems.
1. Fish, seafood and meat
Reduce heavy metals and unwanted processing chemicals.
Fish is one of the healthiest foods we can eat, providing protein, omega-3 fatty acids and important minerals.
However, certain fish accumulate mercury, particularly larger predatory species that live longer and feed on smaller fish.
Processed meats can also introduce compounds formed during curing, smoking and high-temperature cooking.
| Instead of | Choose | Why? |
|---|---|---|
| Swordfish, shark and bigeye tuna | Sardines, salmon or trout | Generally much lower mercury exposure |
| Large predatory reef fish | Smaller, low-mercury fish | Reduces mercury risk and avoids some high-risk reef species |
| Eating tuna every day | Rotate sardines, salmon, anchovies and trout | Reduces repeated mercury exposure |
| Bacon, salami and processed sausages | Fresh unprocessed meat, fish or legumes | Reduces processed meat intake and exposure to curing-related compounds |
| Processed deli meats | Freshly cooked chicken or turkey | Avoids unnecessary preservatives |
| Heavily charred meat | Gently grilled, baked or slow-cooked meat | Reduces potentially harmful cooking byproducts |
| Deep-fried fish | Baked, steamed or poached fish | Avoids degraded frying oils |
| Fish from unknown sources | Traceable, responsibly sourced seafood | Better information about quality and contaminants |
My recommendation: Eat fish regularly, but choose smaller, low-mercury species more often.
Sardines are one of my favourites because they provide omega-3 fatty acids, protein, calcium when the bones are eaten, and generally low mercury levels.
Remember that not all reef fish are safe. Some tropical reef fish can carry ciguatera toxins.
2. Bread, wheat and grains
Choose less processed, nutrient-rich alternatives.
Modern grain production has prioritised yield, consistency and processing characteristics.
Although modern wheat is not automatically less nutritious or more contaminated than traditional varieties, choosing a greater variety of whole grains can improve dietary diversity.
| Instead of | Choose | Why? |
|---|---|---|
| Conventional refined white bread | Organic wholegrain sourdough | More fibre and potentially improved mineral availability |
| Standard refined wheat pasta | Organic spelt, einkorn or emmer pasta | Greater grain diversity and often more wholegrain options |
| Highly processed breakfast cereals | Organic oats or homemade muesli | More fibre and fewer added ingredients |
| Refined wheat flour | Wholegrain heritage wheat or buckwheat flour | Greater wholegrain intake |
| Rice every day | Rotate quinoa, buckwheat, oats and rice | Reduces repeated exposure to rice-associated arsenic |
| Rice milk | Unsweetened oat milk or another suitable alternative | May reduce inorganic arsenic exposure |
| Packaged pastries | Homemade baked foods | Greater control over ingredients |
| Highly processed wraps | Wholegrain sourdough or minimally processed flatbreads | Fewer unnecessary ingredients |
What about European heritage grains?
Einkorn, emmer and spelt are traditional wheat varieties that can provide useful alternatives to highly refined wheat products.
However, they still contain gluten and are unsuitable for people with coeliac disease.
Choosing organic versions may reduce exposure to certain pesticide residues, although organic does not mean pesticide-free.
My recommendation: Focus on whole grains, traditional fermentation and dietary variety rather than avoiding all wheat.
3. Fruit and vegetables
Reduce pesticide exposure without reducing your nutrient intake.
Fruit and vegetables are essential for good health. They provide fibre, vitamins, minerals, polyphenols and naturally occurring nitrates that support important physiological functions.
However, pesticide residues vary considerably between crops, and some fruits and vegetables are more likely to contain detectable residues than others.
The good news is that you don’t need to buy everything organic. You can make smarter choices.
| Instead of | Choose | Why? |
|---|---|---|
| Conventional strawberries and other berries | Organic berries, pineapple, kiwi or papaya | Some berries frequently carry multiple detectable pesticide residues |
| Conventional spinach and kale | Organic leafy greens, cabbage or broccoli | Some leafy vegetables have relatively frequent pesticide detections |
| Conventional apples, peaches and nectarines | Organic versions, avocado, mango or pineapple | May reduce exposure to certain residues |
| Conventional grapes and cherries | Organic versions, watermelon or cantaloupe | Useful lower-residue alternatives in some monitoring programmes |
| Conventional capsicums and green beans | Organic versions, asparagus or cauliflower | Can reduce exposure to certain pesticide residues |
| Precut packaged fruit | Fresh whole fruit | Less packaging and greater control over preparation |
| Canned tomatoes | Tomatoes in glass jars | Reduces potential exposure to can-lining chemicals |
| Produce with unknown origins | Seasonal produce from traceable growers | Better sourcing transparency |
My simple rule: buy organic where it matters most
Prioritise organic options for foods that frequently contain multiple pesticide residues, especially berries, grapes and certain leafy greens.
For other foods, choose fresh, seasonal and locally grown options where possible. Local produce isn’t automatically lower in pesticides, but knowing the grower can improve transparency.
Always wash your fruit and vegetables
Even organic produce should be washed. My recommended routine is simple:
- Rinse thoroughly under running water.
- Rub the surface or use a clean vegetable brush for firm produce.
- Remove damaged outer leaves where appropriate.
- Dry with a clean cloth or paper towel.
Some people use diluted vinegar when washing produce. This may reduce certain surface microorganisms, but it is not a reliable method for removing all pesticide residues. Running water remains the standard recommendation.
Most importantly, don’t stop eating fruit and vegetables because you’re worried about pesticides. Their established health benefits generally outweigh the risks associated with typical regulated pesticide residues.
4. Cooking oils, fats and dairy
Reduce unnecessary additives and damaged cooking fats.
The type of fat we eat matters, but so does how we cook with it.
Repeated heating, particularly during commercial deep-frying, can cause oils to deteriorate and produce oxidation compounds.
| Instead of | Choose | Why? |
|---|---|---|
| Repeatedly heated frying oils | Fresh extra virgin olive oil or suitable cooking oils | Reduces exposure to oxidation products |
| Deep-fried takeaway foods | Baked or lightly sautéed foods | Avoids degraded cooking fats |
| Poor-quality olive oil | Verified extra virgin olive oil | Better quality assurance and beneficial polyphenols |
| Products containing partially hydrogenated oils | Olive oil or non-hydrogenated fats | Avoids industrial trans fats |
| Sweetened flavoured yoghurt | Plain natural yoghurt | Less added sugar and unnecessary additives |
| Highly processed cheese products | Traditional minimally processed cheese | Often fewer emulsifiers and additives |
| Sweetened flavoured milk | Plain milk or unsweetened alternatives | Less added sugar |
My recommendation: Use quality extra virgin olive oil as your main everyday cooking oil. Avoid repeatedly heating oils and minimise deep-fried takeaway foods. Include fermented foods such as natural yoghurt and kefir if you tolerate dairy.
5. Water, coffee and drinks
One of the easiest ways to reduce plastic exposure.
Plastic is now part of almost every stage of our food supply. It is used in packaging, storage, transportation and food preparation.
Microplastics have been detected in drinking water, food and human tissues. Scientists are still investigating the long-term health consequences, but reducing unnecessary exposure is a sensible precaution.
| Instead of | Choose | Why? |
|---|---|---|
| Disposable plastic water bottles | Filtered water in stainless steel or glass | Reduces plastic contact |
| Takeaway coffee cups | Your own stainless steel or ceramic cup | Avoids plastic-lined disposable cups |
| Plastic electric kettles | Stainless steel or glass kettles | Reduces hot-water contact with plastic |
| Plastic tea bags | Loose-leaf tea with a metal infuser | Reduces potential microplastic release |
| Plastic coffee pods | Ground coffee with a reusable metal filter | Less packaging and plastic contact |
| Sugary soft drinks | Water, sparkling water or unsweetened tea | Reduces added sugar |
| Canned drinks | Glass bottles where practical | Reduces potential contact with can linings |
| Unfiltered water containing contaminants | Appropriately certified water filtration | Can reduce specific contaminants |
| Artificially coloured drinks | Water flavoured with fresh fruit | Avoids unnecessary colourings |
What about water filters?
Not all water filters are equal.
Activated carbon filters can reduce chlorine and some organic contaminants. Reverse osmosis systems can remove a broader range of dissolved contaminants, including many heavy metals and certain PFAS.
However, filtration performance depends on the specific system and its certification.
My recommendation: Drink filtered water from glass or stainless steel whenever practical, and avoid leaving plastic water bottles in hot cars or direct sunlight.
6. Food storage and cookware
Stop unnecessarily heating food in plastic.
One of the simplest changes you can make is to stop heating food in plastic containers. Heat can increase the migration of certain chemicals from food-contact materials.
| Instead of | Choose | Why? |
|---|---|---|
| Microwaving food in plastic | Glass or ceramic containers | Reduces potential chemical migration |
| Plastic food storage containers | Glass containers | Reduces plastic food contact |
| Plastic chopping boards | Solid wooden chopping boards | May reduce plastic particles released during cutting |
| Scratched nonstick pans | Stainless steel or cast iron | Avoids deteriorating coatings |
| Plastic cooking utensils | Stainless steel or wood | Avoids heating plastic utensils |
| Plastic cling wrap | Glass containers or reusable covers | Less plastic food contact |
| Hot food wrapped in plastic | Glass, ceramic or appropriate food-safe paper | Reduces heat-related migration |
| Unknown grease-resistant food packaging | Verified PFAS-free packaging | Reduces potential PFAS exposure |
My recommendation: Make three changes first:
- Store food in glass.
- Cook with stainless steel or cast iron.
- Never microwave food in plastic.
These changes are relatively easy and reduce unnecessary contact with food-packaging chemicals.
7. Processed and packaged foods
Eat more real food and fewer unnecessary ingredients.
Highly processed foods often contain added sugars, refined starches, salt, flavourings and other additives.
Not all food additives are harmful, and processing itself does not automatically make a food unhealthy. However, diets high in ultra-processed foods are consistently associated with poorer health outcomes.
| Instead of | Choose | Why? |
|---|---|---|
| Ultra-processed ready meals | Freshly prepared meals | Greater control over ingredients |
| Packaged breakfast bars | Nuts, fruit or homemade snacks | Often more fibre and less added sugar |
| Artificially coloured confectionery | Fruit or minimally processed snacks | Avoids unnecessary colours |
| Instant flavoured noodles | Homemade noodles with vegetables | Less sodium and fewer additives |
| Packaged sauces | Homemade sauces using olive oil, herbs and spices | Greater ingredient control |
| Commercial salad dressings | Extra virgin olive oil and lemon | Fewer additives and beneficial fats |
| Highly flavoured protein drinks | Simple-ingredient protein powders or whole foods | Fewer unnecessary ingredients |
| Microwave popcorn bags | Popcorn prepared from kernels | Avoids certain packaging materials |
| Highly processed meat substitutes | Lentils, beans, tofu or minimally processed alternatives | More fibre and often fewer additives |
| Sweetened plant milks | Unsweetened varieties | Less added sugar |
My recommendation: Look at the ingredient list. Choose foods that provide fibre, protein, vitamins, minerals and beneficial plant compounds rather than simply focusing on calories. The goal is to improve the overall quality of your diet.
8. Chemicals around the home
Your environment matters too.
Food is only one source of environmental exposure. Household cleaning products, fragrances, pesticides, dust and indoor air pollution can all contribute.
| Instead of | Choose | Why? |
|---|---|---|
| Synthetic air fresheners | Fresh air and ventilation | Reduces unnecessary fragrance emissions |
| Heavily fragranced cleaning products | Fragrance-free alternatives | Reduces exposure to fragrance irritants |
| Aerosol cleaning sprays | Liquid products applied to cloths | Reduces inhalation of airborne droplets |
| Routine indoor insecticide spraying | Screens, traps and pest prevention | Reduces pesticide use |
| Dry dusting | Damp dusting and HEPA vacuuming | Reduces airborne dust |
| Strong synthetic perfumes | Fragrance-free personal care | Reduces unnecessary fragrance exposure |
| Old deteriorating foam furniture | Certified low-emission furniture | May reduce certain chemical exposures |
| Poor indoor ventilation | Regular ventilation and appropriate air filtration | Reduces indoor pollutant concentrations |
| Wearing outdoor shoes indoors | Shoes-off household | Reduces tracked-in dust and contaminants |
| Frequent scented candle burning | Better ventilation and less indoor combustion | Reduces particulate emissions |
Don’t forget household dust
Household dust can contain pesticide residues, flame retardants, plastic-associated chemicals and other pollutants.
Regular vacuuming with a HEPA filter, damp dusting and removing shoes indoors are practical ways to reduce exposure.
9. Get more nutrition from your food
Reducing toxins is only half the picture.
While reducing unnecessary chemical exposure is important, we should also think about the nutritional quality of the foods we eat.
Research comparing historical and modern food composition has identified declines in selected nutrients in certain crops. For example, a widely cited analysis of 43 garden crops compared US food composition data from 1950 and 1999. It reported statistically significant declines in several nutrients, including protein, calcium, phosphorus, iron, riboflavin and vitamin C.
However, these changes were not universal, and differences in crop varieties, measurement techniques and agricultural practices complicate historical comparisons.
The important message is that food quality and dietary diversity matter.
How to improve your nutrient intake
| Instead of | Choose | Nutritional advantage |
|---|---|---|
| Eating the same vegetables daily | Rotate different coloured vegetables | Broader range of phytochemicals |
| Refined grains | Whole grains and legumes | More fibre and minerals |
| Long-stored produce | Fresh seasonal produce | May preserve certain sensitive nutrients |
| Overcooked vegetables | Lightly steamed or appropriately cooked vegetables | Can preserve some nutrients |
| Low-fibre processed foods | Vegetables, legumes, fruit and whole grains | Supports gut health |
| Sugary breakfast cereals | Oats, nuts and seeds | More fibre and nutrient density |
| Highly processed snacks | Nuts, seeds and fresh fruit | More beneficial fats and micronutrients |
Don’t overlook dietary nitrates
One nutrient-related area I am particularly interested in is dietary nitrate.
Nitrate-rich vegetables such as rocket, spinach, beetroot and certain leafy greens provide nitrate that the body can convert into nitric oxide.
Nitric oxide plays important roles in vascular health, blood flow, blood pressure regulation and cellular signalling. Our ability to produce nitric oxide through some endogenous pathways also changes with ageing.
This makes maintaining healthy nitric oxide production an important consideration for long-term health. If you’d like to know where you currently sit, Nitric Oxide Test Strips give you a simple saliva reading in about 15 seconds.
10. You can’t avoid every toxin
That’s why supporting your body’s natural protective systems matters.
Even if you eat organic food, filter your water, avoid plastics and use natural cleaning products, you cannot completely eliminate environmental exposure. Pesticides, microplastics, heavy metals, air pollution and other contaminants are present throughout our environment.
Reducing exposure is the first step. Supporting your body’s normal protective and elimination systems is the next.
Fortunately, your body already has sophisticated systems for processing and eliminating unwanted substances.
Your liver
Your liver uses specialised enzymes and biochemical pathways to transform many substances into forms that can be eliminated. These processes require adequate nutrients and depend on normal metabolic function.
Your kidneys
Your kidneys continuously filter your blood, regulate fluid and electrolyte balance, and remove many water-soluble waste products. Healthy kidney function is essential for maintaining the body’s internal environment.
Your gut
Your digestive system helps eliminate waste and certain substances through bile and bowel movements. A healthy intestinal barrier and diverse gut microbiome also contribute to normal digestive and metabolic health.
Your antioxidant systems
Environmental exposures can contribute to oxidative stress. Your body relies on antioxidant systems, including glutathione-related pathways and antioxidant enzymes, to protect cells from oxidative damage. These systems depend on adequate nutrition.
Your circulation
Healthy circulation delivers oxygen and nutrients throughout the body, including to the liver and kidneys. Nitric oxide is one of the body’s important regulators of vascular function, and supporting normal nitric oxide production may help maintain healthy circulation.
11. How BOOST and Ultimate 4 support healthy ageing
Reducing exposure to environmental contaminants is important. But so is providing your body with the nutrients and physiological support it needs to function properly.
This is where I see two complementary areas of support.
BOOST: nutritional, antioxidant and cellular support
BOOST combines spirulina and other green superfoods with medicinal mushrooms and herbal ingredients. These provide a range of nutrients and naturally occurring plant compounds.
The formula is designed to complement a healthy diet by supporting:
- Antioxidant nutrition – plant compounds and nutrients contribute to the body’s normal antioxidant defences.
- Cellular health – adequate micronutrients support normal energy metabolism and cellular function.
- Gut health – a varied, plant-rich diet supports microbial diversity and digestive health.
- Healthy ageing – good nutrition is fundamental to maintaining normal physiological function as we age.
BOOST is designed as a convenient way to complement your daily plant and nutrient intake.
Ultimate 4: nitric oxide, circulation and vascular support
Ultimate 4 approaches healthy ageing from a different direction.
It combines nitrate-rich beetroot and rocket extracts with L-citrulline, vitamin C, glycine, taurine and other ingredients. These nutrients are selected to support nitric oxide production, availability and related physiological functions.
Why nitric oxide matters
Nitric oxide is a signalling molecule involved in several essential processes:
- Healthy blood vessels – nitric oxide helps blood vessels relax and supports normal vascular function.
- Blood flow – it plays an important role in regulating circulation and vascular resistance.
- Oxygen and nutrient delivery – healthy circulation supports the delivery of oxygen and nutrients throughout the body.
- Kidney circulation – nitric oxide contributes to the regulation of blood flow within the kidneys.
- Cellular function – it participates in cellular signalling and interacts with pathways involved in mitochondrial function and metabolism.
- Healthy ageing – maintaining normal endothelial function and nitric oxide signalling is an important part of cardiovascular health.
You can read more about why I see nitric oxide as a foundation of healthy ageing on my nitric oxide page.
Why I like combining the two
BOOST provides complementary plant-based nutritional and antioxidant support. Ultimate 4 focuses on nitric oxide production and healthy circulation. Together, they offer two different forms of support for normal physiological function.
If you’d like both together, the Heart & Energy Bundle pairs Ultimate 4 and BOOST with Nitric Oxide Test Strips so you can track your levels as you go.
It is important to understand that neither product has been clinically proven to remove microplastics, heavy metals, pesticides or other environmental toxins from the body. Their role is nutritional, antioxidant and vascular support, not a replacement for reducing exposure or treating toxic contamination.
People with kidney disease, low blood pressure or those taking blood-pressure medication should seek individual medical advice before using nitrate-rich supplements.
12. My top 10 low-tox changes
Start here if you want the biggest practical improvements.
You don’t need to change everything overnight. I would start with these ten habits.
| Priority | Make this change | Main benefit |
|---|---|---|
| 1 | Replace high-mercury fish with sardines, salmon and trout | Lower mercury exposure |
| 2 | Stop heating food in plastic containers | Reduces potential chemical migration |
| 3 | Use filtered water in glass or stainless steel | Reduces unnecessary plastic contact and selected water contaminants |
| 4 | Buy organic selectively for higher-residue produce | May reduce pesticide exposure |
| 5 | Replace heavily processed foods with whole foods | Improves overall dietary quality |
| 6 | Use stainless steel or cast iron cookware | Reduces reliance on deteriorating nonstick coatings |
| 7 | Avoid repeatedly heated frying oils | Reduces exposure to oil oxidation products |
| 8 | Use fragrance-free household products | Reduces unnecessary fragrance exposure |
| 9 | Eat a wide variety of vegetables, legumes and whole grains | Supports nutrient intake and gut health |
| 10 | Support normal antioxidant and vascular function through nutrition, exercise and healthy lifestyle habits | Supports long-term physiological health |
Small low-tox changes that add up
You can’t control everything you’re exposed to. But you can control a lot.
We live in a world where chemical exposures are difficult to avoid completely. Some are well-established health hazards at sufficient doses. Others, including many potential effects of microplastics, are still being investigated.
The aim isn’t to become frightened of food or obsessed with eliminating every trace of a chemical. The aim is to make better choices consistently:
- Choose lower-mercury fish.
- Eat a greater variety of whole foods.
- Reduce unnecessary plastics.
- Use cleaner cooking and storage methods.
- Improve the quality of your drinking water.
- Reduce unnecessary household chemical exposures.
And importantly, provide your body with the nutrition, physical activity, sleep and healthy circulation it needs to function well.
This is also why I developed BOOST and Ultimate 4: to complement a healthy lifestyle through nutritional, antioxidant and nitric oxide support.
They are not shortcuts or substitutes for healthy habits. They are additional tools that can form part of a broader approach to healthy ageing.
Reduce the exposure. Improve the nutrition. Support the body.
Small changes, repeated every day, can make a meaningful difference over a lifetime.

Frequently asked questions
Which fish are lowest in mercury?
Smaller species such as sardines, salmon, trout and anchovies generally carry much lower mercury than larger predatory fish like swordfish, shark and bigeye tuna. Rotating several low-mercury fish rather than eating tuna every day also reduces repeated exposure.
Do I need to buy all my produce organic?
No. Prioritise organic for foods that frequently carry multiple pesticide residues, especially berries, grapes and certain leafy greens, and choose fresh, seasonal produce for the rest. Wash all produce, including organic, under running water.
Is it safe to microwave food in plastic containers?
It is best avoided. Heat can increase the migration of certain chemicals from food-contact materials, and one study found microwaving food in plastic containers released far more plastic particles than other uses. Glass or ceramic containers are a simple swap.
What type of water filter reduces PFAS?
Activated carbon filters can reduce chlorine and some organic contaminants, while reverse osmosis systems can remove a broader range, including many heavy metals and certain PFAS. Performance depends on the specific system and its certification.
Can supplements remove microplastics or pesticides from the body?
No product has been clinically shown to remove microplastics, heavy metals or pesticides. The role of nutritional supplements is to support normal antioxidant, nutritional and vascular function, alongside reducing exposure.
