This post is not meant to drive you crazy. It’s not meant to turn your life upside down and be paranoid about everything you and your family are exposed to.
In fact, most of the toxins discussed in the article don’t harm you unless you are exposed to extremely high levels on a consistent basis or if your body is unable to process them safely.
History has shown us that everything is toxic and it is only the dose that separates the toxic from the non-toxic.
Merriam Webster’s definition of ‘toxin’ is:
A poisonous substance that is a specific product of the metabolic activities of a living organism and is usually very unstable, notably toxic when introduced into the tissues, and typically capable of inducing antibody formation.
By this definition, many typical toxins (ie. car fumes, additives, synthetic chemicals) are not poisonous, life threatening, or are created by a living organism.
For simplicity’s sake, this article will refer to “toxin” as a synthetic or non-synthetic molecule or state of mind that has the potential to negatively affect the body in moderate amounts over the course of a person’s life. This may be a vague definition but it is the accumulation and toxic burden that negatively affect people the most. It’s not often one singular exposure.
Our bodies are designed to handle daily toxic exposures, in fact it is can be healthy to challenge your immune system and detoxification pathways. Living in a sterile environment has it’s dangers, especially with children.
The body needs to maintain a balance between Th1 and Th2:
It has been hypothesized that the decrease of infections (Th2) in Western countries and more recently in developing countries is at the origin of the increasing incidence of both autoimmune and allergic diseases (Th1). This is called the “hygiene hypothesis.” It is based upon epidemiological data, particularly migration studies, showing that subjects migrating from a low-incidence to a high-incidence country acquire the immune disorders especially with first generation.
More simply:
- Th2<Th1: If a child grows up in a clean, semi-sterile environment (low Th2) studies have seen an increase in autoimmune, asthma and allergic conditions (high Th1).
- Th2>Th1: Alternatively, if a person is exposed to many micro-organisms, such as bacteria and parasite infections (high Th2), it has been shown to reduce humoral allergic incidences (low Th1).
Ideally, we should aim to have balanced Th1 and Th2 systems (Th1=Th2).
This is why I say “limit toxin accumulation” in the title of this article and not “avoid toxins.” Some exposure to toxins, micro-organisms, and substances that challenge our immune system is crucial to find optimal health.
So far we’ve learned that everything is toxic and it is only the dose that separates the toxic from the non-toxic and a moderate amount of toxins are required for a healthy immune system.
There are however, natural toxins that could have deleterious effects even at small doses (ie. food poisoning, heavy metals), but for the most part, it is the accumulation that stresses our bodies and have them working sub-optimally.
We take in toxins in a variety of ways, including external and internal processes. My recommendation is NOT to make all these changes. And if you have already, I would question if your “healthy lifestyle” is more of an obsession. There are dangers in going too far, it’s called orthorexia. Limiting some of these toxic exposures and accumulations one step at a time will bring you closer to optimal health and vitality.
Limiting External Toxin Accumulation
We’ve already learned that everything is toxic and it is only the dose that separates the toxic from the non-toxic. There are however, natural toxins that could have deleterious effects even at small doses (ie. food poisoning, heavy metals), but for the most part, it is the accumulation that stresses our organs of elimination and have our bodies working sub-optimally. We take in toxins in a variety of ways, including external and internal processes:
External toxins or extrinsic factors are the most common factors that people think of when it comes to their health. It is anything from the things we consume, absorb, inhale, observe or hear.
This list consists of common toxins we are exposed to on a daily basis and excludes major infections such as E. coli and C. difficile, side effects of vaccinations and specific medications.
CONSUMPTION:
Processed foods, preservatives and additives
SOLUTION – Give your body a break from heavy chemicals and irritants in many of the foods we eat by:
- Washing your produce with more than just water (learn an easy DIY produce wash recipe)
- Buying organic, local and seasonal produce (especially the “Dirty Dozen”)
- Avoiding detrimental additives such as artificial sweeteners, high fructose corn syrup, MSG, trans fats, olestra, food dyes, sodium chloride/ sulfite/ nitrate/ nitrite, BHA/ BHT/ propyl gallate, sulfur dioxide, potassium bromate and parabens
Excessive amounts of sugars and soda
SOLUTION – Avoid candy, concentrated juices and soda pop by replacing them with healthier options (read Are You Eating Yourself Sick?)
- Raw fruits and veggies (ie. apples, avocados, oranges, peppers, tomatoes, cucumber, carrots, celery)
- High protein snacks to help with satiation and blood sugar regulation (ie. nuts, protein shakes, beans, meat)
- Drink more water and fresh juice
Poor water quality
SOLUTION – Limit bottled water and drink purified, re-mineralized and alkaline water to avoid water contaminants but maintain beneficial mineral content
- Distillation, gravity-fed filtration systems, reverse osmosis and carbon filter may be potential options depending of your current quality of water (Read more about The Best Water Quality, Products and Filtration Systems)
Heavy metal seafood
SOLUTION – Avoid seafood and fish at the top of the food chain, which contain high levels of mercury. See this link for the EPA’s safe amounts of mercury in shellfish and fish.
- Avoid shark, tuna, swordfish, king mackerel which are predator fish with higher amounts of mercury
- Stick to shrimp, sardines, anchovies, salmon, pollock, catfish and smaller fish (even in your fish oil)
- Eat up to 12 ounces (2 average meals) a week of a variety of fish and shellfish that are lower in mercury.
Packaging coated with PFCs and heated plastics
SOLUTION – Avoid food wrappers, pizza boxes, microwavable popcorn and other PFC (perfluorinated compounds) products, especially when re-heating.
- Purchase responsible pre-packaged goods without PFC
- Transfer microwavable foods to glass, ceramic or other safe to heat containers
- Re-heat your food on the stove or in the oven when possible
- Try to cook and eat fresh foods whenever possible
Rancid oils
SOLUTION – Oil-containing foods such as nuts, avocado, seeds, fish and olive oil spoil with different temperatures and environmental factors. To be on the safe side, practice the following tips, and read more about Are You Eating Yourself Sick?:
- Keep oils refrigerated, sealed air tight, and in a dark room (ie. fridge)
- Consume within 3 month
Not cooking or washing foods properly
SOLUTION – Especially when it comes to pork, chicken, turkey, fish and seafood, make sure they are cooked appropriately to limit the number of bacteria and parasite infections. Similarly, little critters can live among leafy greens and produces with a high surface area, such as broccoli.
- Use a meat thermometer to estimate how cooked a thick piece of meat (temperature food guide)
- Soak your produce for 10 minutes in a solution of water, salt, vinegar, and grapefruit seed extract (get the DIY produce wash recipe)
Charcoal grilling
SOLUTION – Summer often means BBQ, but it also means volatile organic compounds (VOCs). The burnt crust on your steaks and veggies are carcinogenic in large quantities.
- Limit your consumption of charcoal crispy bits of fatty meats and high oil vegetables from the BBQ but also skillet and oven
- Try eating raw, steamed or poached foods more often
Misused Teflon cookware
SOLUTION – Consuming the Teflon of non-stick pans contains the toxic compound Polytetrafluoroethylene (PTFE), which can cause flu-like symptoms when consumed.
- Avoid metal and use plastic or wooden utensils on non-stick Teflon pans
- Throw out misused Teflon pans that have scratches or pieces of Teflon flaking off
- Switch to stainless steel or cast-iron pots and pans
Stay tuned and stay healthy!
