What is heavy metal toxicity? A nutritionist explains how it could impact your health

The concern over mercury, and other heavy metal toxins is a hot, and controversial topic for people who worry about their health. As a nutritionist, when my patients give me their medical history, more are mentioning heavy metal toxicity. Others are asking if they need a heavy metal detox. Many of these people are dealing with health issues and symptoms they can't easily find an explanation for — but that does not mean they have heavy metal poisoning.
