A new report, published in the journal Archives of Toxicology indicates that consuming purple fruits that are rich in antioxidants, like blueberries, may help to protect against some chronic illnesses that are caused by poorly bound iron.
According to Professor Douglas Kell from the University of Manchester in the UK, iron in the body that is not properly bound together can cause dangerous toxins, known as hydroxyl radicals, to be produced.
Kell indicates that hydroxyl radicals can cause degenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD). According to the Centers for Disease Control and Prevention, AD is the most common form of dementia among the elderly population in the United States.
To protect the body from iron complications that produce toxins, it is crucial for people to consume the proper amount of nutrients that are considered to be iron chelators, which can help to bind iron together, according to the report. Bright-colored fruits and vegetables as well as green tea are sources of chelators. Purple fruits, like blueberries, are considered to be highly effective for the binding of iron.
Iron complications speed up the process of chronic illnesses like AD, Kell argues. And while vitamin C is known to combat toxins, it does not necessarily work unless iron is in its correct form. However, vitamin C can have a positive impact if iron is properly bound together.
