Chemical Pollutants Can Reduce Levels Of Vitamin D

| October 22, 2016

As I mentioned in my last blog post, we all need extra vitamin D, particularly through the winter period. But it isn’t only the lack of sunshine that can deplete your body’s stores of vitamin D, it’s also the chemical pollution we are all exposed to. Scientists have recently shown that higher levels of endocrine-disrupting chemicals (EDCs) in the body are linked with vitamin D deficiency.

EDCs damage our health by interfering with the action of hormones. It is not surprising that they disrupt vitamin D, too, since it acts very much like a hormone in the body (see my earlier post here). The health problems EDCs can cause include obesity and diabetes, as well as infertility, neurological problems and hormone-related cancers. These toxic chemicals are found in everyday consumer products, including food packaging, and are present throughout the environment.

Two of the most damaging groups of EDCs are bisphenol A (BPA) and phthalates. When researchers at the University of Michigan, USA analysed data from 4,667 adults, they found a clear relationship between higher exposure to phthalates and lower vitamin D levels.1 BPA was also linked with low levels of vitamin D, but the association was stronger in women than in men.

So, as well as taking a daily supplement of 50 micrograms or 2000 IU a day of vitamin D (make sure it’s the D3 form, which is best utilised by the body), it pays to limit exposure to EDCs as far as possible. Here are some steps that help:

  • Avoid using air fresheners, odour eliminators and fabric conditioners
  • Pick natural, fragrance-free creams, cleaning products, and detergents
  • Keep your house clean by dusting with a damp cloth and using
    a vacuum with a HEPA filter
  • Wash your hands before meals and after using household chemicals
  • Don’t use plastic food or drink containers, sandwich bags or cling film
  • Avoid canned foods – cans are often coated with BPA
  • Drink filtered or mineral water and eat organic food when possible

Studies show EDCs contribute to the global epidemic of obesity, insulin resistance and type 2 diabetes.2 But the biggest cause is still likely to be too much fructose in our diet. Now, researchers have discovered exactly why it is so damaging, as I shall explain in my next blog post.
