Toxins and Your Body: What You Need to Know

Practical steps to reduce exposure and support your body’s natural defences.

In today’s world, exposure to environmental chemicals is almost unavoidable. From the air we breathe and the water we drink to the food we eat and the products we use, our bodies interact with countless substances every day. While not all are harmful, some can build up over time and place extra stress on our systems.

Research has shown that diet, lifestyle and environmental exposures can influence long-term health. The good news? By being mindful of where toxins may be found, and by supporting our body’s natural detoxification pathways, we can reduce the burden and promote better wellbeing.

Common Sources of Toxins

Some of the most common sources of environmental toxins include:

• Pesticides and herbicides on conventionally grown produce.

• Plastic packaging that can leach chemicals such as phthalates.

• Household cleaning and personal care products containing synthetic fragrances and volatile organic compounds (VOCs).

• Heavy metals such as mercury and lead, which can be present in fish, water, or old building materials.

• Air pollutants from traffic, industry and burning fuels.

How Toxins Affect the Body

Over time, low-level, consistent exposure to toxins may contribute to imbalances in the body. These may affect systems such as:

• Liver and detox pathways (responsible for filtering and neutralising toxins).

• Immune system (potential overactivation or suppression).

• Hormones (some chemicals mimic or disrupt natural hormones).

• Brain and nerves (certain toxins are neurotoxic).

Symptoms are often subtle at first, such as fatigue, headaches, or digestive upset, and may only become more noticeable after long-term exposure.

Practical Steps to Reduce Exposure

While it’s impossible to avoid all toxins, there are simple, effective ways to reduce your overall load:

• Choose organic produce where possible — especially for foods more likely to carry pesticide residues.

• Use natural cleaning products and avoid synthetic air fresheners or fragranced sprays.

• Switch to natural toiletries and cosmetics, free from parabens, phthalates and strong synthetic scents.

• Filter your drinking water, ideally with a carbon block or reverse osmosis system.

• Avoid heating food in plastic containers, and opt for glass or stainless steel for storage.

• Be mindful of fish choices — smaller oily fish (like sardines and mackerel) tend to carry fewer contaminants than larger species.

Supporting Your Body’s Detox Pathways

Your liver, kidneys, skin and gut all play roles in processing and eliminating toxins. You can support these systems naturally by:

• Eating a diet rich in colourful fruit and vegetables, which provide antioxidants to help neutralise free radicals.

• Staying well hydrated to support kidney function.

• Including fibre-rich foods to support bowel regularity.

• Maintaining regular movement and sweating through exercise.

• Ensuring good sleep, when your body performs important repair and clearance functions.

Some nutrients, such as N-acetyl cysteine (NAC), alpha-lipoic acid, and B-vitamins, are widely studied for their role in detoxification pathways. However, supplements are not one-size-fits-all, it’s best to seek advice before adding them.

Final Thoughts
