Are you planning a post-christmas detox and not sure where to look? Whether you are or not, come the first week of January a large majority of us in the UK will be typing the terms ‘detox’ or ‘diet’ into ‘google’ in the hope of finding inspiration online. But with search engines throwing back page after page of results it can be quite difficult to know where to look for a detox plan that actually works.
In today’s article we are going to look at the science and history behind a period of ‘detoxification’ with a view to helping you understand what is happening internally during this cleansing period, and what nutrients are essential to undergo a successful detox.
The idea of a ‘detox’ has been around for centuries and is a cleansing method that has been adopted by various cultures throughout history. The original premise of detoxification is based on the ancient Greek and Egyptian theories that much of the food we eat contains toxins that are harmful to the body and most ancient civilisations advocated a day of self-denial or fasting because of this.
Although a ritual that goes back centuries, supporting the body’s natural detoxification systems (ideally all year as well through our food choices) is arguably more important now than it has ever been. We exist in a toxic environment: pesticides sprayed on vegetables, phthalates in plastics and cosmetics, chlorine in household cleaners, PCB’s and heavy metals in farm-raised fish, and antibiotics and dioxins in commercially produced animal products are just a few examples of toxins that are in most people’s environment every day.
A study in the US showed the average woman puts around 168 chemicals onto her body every day in the form of cosmetic products. Even if we eat organic foods, avoid commercial cleaners, and are careful in our choice of skincare products, we cannot avoid the pollution in our environment and some toxins are increasing; according to the Environmental Protection Agency, releases of toxins on land rose by 19 percent from 2010 to 2011, primarily due to increases in land disposal at metal mines.
Supporting the functions of the liver, bowel, skin and circulation are key objectives of detoxification. So a healthy diet, high in fibre to support regular bowel movements, with liver supportive nutrients will support the detoxification and elimination of toxins from our body.
Inside the liver cells there are mechanisms that have evolved over centuries to break down and neutralise toxic substances that enter our bodies – both ‘exogenous’ toxins (ie from the outside) such as drugs, pesticides and pollutants and ‘endogenous’ substances produced in the body such as hormones. All of these are metabolised by enzyme pathways inside the liver cells. These detoxification processes occur every day, not just when we are on a detoxification diet. Sometimes the body’s capacity to deal with toxins is exceeded and this results in toxins being stored away in fatty tissues in the body.
Toxins may be stored for years in fatty tissues before being released during times of exercise, stress or fasting. During the release of these toxins, symptoms such as headaches, poor memory, stomach pain, nausea, fatigue, dizziness and palpitations may occur. To avoid these symptoms it is preferable that your body is in a relatively nutritionally ‘replete’ state.
Starting a detox programme from a nutritionally depleted state, along with an inadequate intake of key nutrients during the detox can mean that your body is less able to support the detoxification process. Particular nutrients to be mindful of in this respect are minerals such as zinc, copper, magnesium, manganese, molybdenum, selenium and the antioxidants vitamins C and E.
The liver has two pathways designed to convert fat-soluble chemicals into water soluble chemicals so that they may then be easily excreted from the body via watery fluids such as bile and urine: Phase I (oxidation, reduction and hydrolysis reactions) and Phase II (conjugation reactions).
Phase I detoxification involves oxidation, reduction and hydrolysis. Phase I, which is catalysed by enzymes referred to as cytochrome P450 enzymes, converts harmful chemicals into (mostly) less harmful substances and in the case of fat soluble toxins makes them more water soluble allowing them to be much more efficiently excreted from the body via the bile (and bowel) or kidneys. This is achieved by various chemical reactions which also results in free radicals being produced. Antioxidants such as vitamins C, E and natural carotenoids are needed to reduce the damage caused by these free radicals.
In Phase I, some toxins are converted into more dangerous substances that are carcinogenic. Also excessive amounts of some toxic chemicals such as pesticides can disrupt the P450 enzyme system causing over-activity of this pathway and leading to high levels of damaging free radicals being produced.
Intermediates from Phase I enter Phase II to complete the detoxification process. As mentioned, some of the Phase I intermediates are more dangerous than the initial toxin. For example, benzene, is a dangerous organic solvent that is present in gasoline and cigarettes. The enzymes in ‘phase 1’ oxidize benzene to produce benzene quinones , which are carcinogenic. To efficiently and safely complete the detoxification of benzene, the body requires ‘Phase II’.
In Phase II, oxidised chemicals are combined (or conjugated) with amino acids, sulphur or organic acids and then excreted in the bile.
This phase of the process is particularly affected by nutritional deficiencies and overload of toxic exposure.
The most important amino acids for Phase II detoxification are cysteine and methionine These two amino acids are the main dietary sources of sulphur, and are found in meat, fish, poultry, eggs and dairy products. Vegetarian sources of cysteine and methionine include nuts, seeds and beans. The body’s requirement for cysteine and methionine fluctuates depending on the liver’s burden of toxic compounds. The body’s stores of these amino acids are depleted in the process of detoxification, so the greater the toxic stress, the more the body demands. This is why it is important to include some (but not excessive) protein foods in a detoxification programme.
Once toxins have been ‘neutralised’ by the liver they may enter the bile and then the bowel to be eliminated in the faeces. If you are constipated some of these toxins will be reabsorbed and may have to go through the liver’s detoxification processes a second time. Regular (at least daily) bowel movements to ensure elimination are an essential part of a detoxification.
There are a number of supplements to consider to support the gut and liver with detoxification. Here is a selection with some information to help you choose the most appropriate ones for you if you are planning a detox in January:
Multivitamin and Mineral providing a range of B vitamins, vitamins C, D and trace minerals is a base to ensure you are getting adequate levels of all nutrients.
Detox Support – This supplement which can be taken alongside a multivitamin and mineral is designed for short-term use (1-2 months). It contains additional vitamin C, manganese, zinc, garlic and spirulina.
Live Bacteria – to support a healthy gut flora balance.
Fibre supplements – Whole Linseeds or Psyllium, if needed, to produce regular and ample bowel movements. Bowel movements should be at least once daily, during a detox diet bowel movements may be more frequent although they should still be ‘firm’.
Aloe Vera – Aloe Vera has anti-inflammatory properties.
Slippery Elm Bark – this is high in mucilage and is used for its soothing properties on the gut.
Milk Thistle – Tradition has recorded the use of this herb as part of a cleansing programme.
Spirulina – This is a type of blue-green algae high in chlorophyll which is used in detoxification programmes.
Phyte-Inflam – This contains curcumin, ginger and piperine which have anti-inflammatory properties.
Phytoshield – This contains carotenoids and flavonoids which are anti-oxidants.
Magnesium Citrate – Magnesium is involved in over 300 biochemical pathways in the body including detoxification pathways.
Look out for our blog on Wednesday 6 January when we will be giving some diet ‘Do’s’ and ‘Don’ts’ to support a healthy detox.
Warning on Detoxification Diets
The information in this blog includes suggestions as part of a detoxification programme. We would not consider it appropriate to carry out a detoxification during pregnancy or breastfeeding. However a detoxification as part of preconception planning can be beneficial for both the mum and dad-to-be.
If you have any pre-existing medical conditions or are taking medication, please consult your doctor first before embarking on a detoxification diet. You should not undertake a detoxification diet if you are unwell without supervision from a healthcare practitioner.
If you have any questions regarding the health topics that have been raised, or any other health matters please do contact me (Amanda) by phone or email at any time.
