All right, gang, you flooded my inbox this week. I can certainly think of worse problems to have, though. (People read the blog! A whole lot of people, as it turns out). I always answer as many emails as I can. If you don’t hear from me, it’s a good idea to talk about your health questions in the forum, so that if I don’t answer them, someone sure will – a very encouraging and interesting gang, as you’ll find.
This week, I got a whole slew of questions about my controversial case against cardio, my antipathy towards carbs, what food I eat in a day, and oddly, not one but several emails about spirulina.
“Mark, is it true that spirulina is a good source of Omega-3’s? Is it better than fish oil?”
Sorry, but spirulina is a very poor source of Omega-3’s – a dose of fish oil has ten times the amount. I have a bit of a beef with spirulina supplements, because while it’s technically true that spirulina is a good vegetarian protein as well as containing beneficial fatty acids, the amounts are seriously microscopic. You’d literally have to consume spirulina breakfast, lunch, and dinner to get even a minimal amount of nutrients you can easily get from consuming just a few servings of wild salmon or even olive oil every week. This is something I see in general with a lot of supposed “miracle food” supplements. I won’t name names (for now) but potency means zip if the dose itself is puny. Look at grams per serving, always.
“Mark, how do I find out my nutritional type?”
Oh, boy. This is one that just persists and persists. I am not a fan of body-typing for diet or anything else, apples. Something you learn in Biology 101 is that we all share the same metabolic pathways – so we should all stay away from the same things – sugar, namely. It’s just that some of us are better at extracting and storing calories than others (see the Bees’ coverage of gut bugs). The problem is simple, but very common (like 65% of Americans share it!).
