Lead poisoning is responsible for many chronic illnesses, including renal failure. Unfortunately, this toxin is nearly omnipresent in most environments, wreaking stealthy havoc in the lives of many. The obvious solution to the lead problem is to remove it, but what can one do if he/she is suffering the ill-effects of lead poisoning? A 2013 Biological Trace Elements Research report provides hard evidence regarding the efficacy of flaxseed oil consumption stemming the tide of lead-induced sickness. Flaxseed oil, with its omega-3 and lignans, empowers your anti-oxidant defense mechanisms. The body has an internal warring mechanism and flaxseed oil helps to rally the troops to fight against the development of certain heart and kidney diseases. Your body knows how to fight and is good at it- and flaxseed is one thing that can help it.
