(Hu)man vs Food (Outside magazine)

A very good start, but I wonder if some the lab results lagged behind the diet being implemented? I'd also like to see how a sprinter or weightlifter would fare with the different diets. I know when I was a competitive weightlifter, I ate a high-protein high-fat diet and I my bloodwork and bodyfat % was fantastic. Now that I'm primarily doing cardio work, I gain weight when I eat a lot of protein/fat. That said, my cholesterol and blood sugar numbers aren't nearly as as good (though HDL/LDL is still very good). Is that due to diet or age/genetics?

And I also wonder about the ethnicity argument. According to family history, I'm mostly Irish. But based on my mother's and father's DNA results, I'm pretty much a European mutt... heavy on Irish, Nordic, German, and Italian. So does that mean I can eat chicken, tomatoes, and coffee (which the author was told to avoid)? Because that makes up about half my diet. {I don't want to do the work to find out, just want someone to tell me. LOL!}

Still, once again, the advice pretty much boils down to lean proteins, good fats, and healthy carbs (as the author states). Though I wonder what the nutritionist would think of my Sour Patch Kid diet when I hike at altitude?
