Until ADAPT I’ve always heard it as a two figure number X to Y, but you often say when talking about test results for instance had a ratio of X. I can usually work out what this means maybe given context, but it’s harder. Can you explain how a ratio is something in comparison to something else and how can we know which the two things we’re talking about?

Chris Kresser: Yeah, you divide the numerator by the denominator and you get one number. And then it’s expressed as the numerator. So if you have the zinc-copper ratio, you divide zinc by copper and you get let’s say 0.75. Then the denominator in that would be 1 and the numerator is 0.75. So we’re just saying 0.75 instead of 0.75 to 1. And that’s actually how it’s often expressed in the scientific literature as well. So I find it easier to say that and it’s also just more consistent with how it’s expressed in the literature.
