Are toxins in fast food compromising your health?
By Louise Belle Nutritionist for Cabot Health
It is common knowledge that fast food contains high amounts of sugar, oxidized fats and trans-fats and sometimes extra additives such as MSG. These things can increase your risk of cardiovascular disease, high blood pressure, type 2 diabetes, and obesity. Even with knowledge of this, millions of people continue to consume fast food on a regular basis. Less known, is that fact that many fast food products also contain added chemical colours and preservatives, that may cause side effects especially allergies or gut irritability. The ingredient lists of our popular fast food chains here in Australia display many undesirable chemicals. Listed below are ten of the key chemicals that you will find in our fast-food and how they can impact your health:
- Sodium nitrate (250): Used to preserve and maintain colour in processed meats and bacon. They can convert to nitrites in the gut, which combine with amines (usually coexisting in these products) to produce nitrosamines which are known carcinogens. They cause behavioural issues in children, rashes and sleep disturbance.
- Colour 160b: Annatto is used in cheese to make it yellow and is associated with headaches, poor sleep and arthritis. Avoid cheeses that look too bright yellow to be true!
- Preservative 282: Calcium propionate, commonly used in breads and wraps is linked to hyperactivity in children, learning difficulties, sleep disturbance and immunosuppression.
- Sulphites (220-228): These preservatives are used in chips and breads and are associated with headaches, runny nose, hives and asthma.
- Preservatives 200 & 202: These sorbates are used to preserve cheese, bread, pickles and mayonnaise and can cause dermatitis, asthma, burning mouth syndrome and IBS.
- Colour 124: The brilliant scarlet colour is used in strawberry syrups and is a known histamine liberator, which can intensify symptoms of asthma, hay fever and rashes and can cause hyperactivity in children.
- Preservative 211: Sodium benzoate is used to prevent moulding in pickles, jalapenos, salad dressing and soft drink. It can be linked to dizziness, sleep problems and DNA damage.
- Colour 102: Tartrazine yellow used to colour sauces is manufactured from coal tar and linked to ADHD, depression, anxiety and migraines.
- Monosodium Glutamate (MSG 621): A flavour enhancer used in chicken, gravy and processed meats. Its known to cause migraines, nausea, chest pain, numbness and heart palpitations.
- Preservatives 627 & 631: Ribonucleotides that are used in salad dressing, gravy and chicken. These increase the effects of MSG and can cause an itchy rash and swelling of the lips.
Next time you go to order your favourite burger, soft drink and fries, think about the negative effects that it could be inflicting on your health. Every time you eat at a fast food restaurant you are further exposing yourself to risk of disease, or adverse health outcomes. Why not humour yourself and ask the staff for their ‘food allergy information book’ and see what chemicals are residing in the food you were about to order.
Not only do we have these chemicals added to our fast food, the packaging used to wrap or hold the food, can transfer additional chemicals onto it. Fluorinated compounds (PFAs) are used to make fast-food wrappers and packaging grease proof. They are also used in carpeting and waterproofing. A recent study in the Journal of Environmental Science & Technology found that 46% of wrappers and 20% of boxes contained fluorine. If the food is hot and contains emulsified fats, the risk of the chemicals leaching into the food is even higher. Studies have linked high exposure to these chemicals with thyroid disorders, immune problems and testicular cancer. It is impossible to distinguish between which fast food packaging contains these compounds and which do not. The best bet is to avoid fast food all together. Instead, choose whole foods that will nourish your body with nutrients.
We also recommend that you avoid using a microwave oven to cook/heat your food, especially in plastic containers. We need to ask ourselves – why is the incidence of bowel cancer rising in younger people? Your health is in your hands, choose your food wisely!
