These days, probably the number one topic of conversation in the health world is immunity. So, it’s very timely that Dr. James DiNicolantonio published his new book The Immunity Fix, which explores the notion that we can have a huge impact on the functionality of our immune systems based on the choices we make every day. He talks about the role of nutrition and the threat of deficiency of various trace minerals, as well as why the balance of immune function is particularly relevant in COVID-19.
