Recently by Mark Sisson: Top 8 Most Common Reactions to Your Grain-Free Diet
Since it seems to be popular with this crowd, and we’re never running out of questionable foods, I figured I’d take the time to put together another round of “Is It Primal?” I got most of these choices from the comment sections of previous posts, along with follow-up emails. As always, feel free to fill in the blanks after the post. I have a strong feeling this will become a recurring series of posts, and I’m going to need plenty of material. Today, we’re talking about seven foods: sprouts of all kinds and origins; agave nectar, nectar of the metabolic syndrome gods; soy lecithin; coconut aminos, what hipsters have moved onto from tamari; tapioca, gummy starch; animal skin, food of the gods; and Quorn, “food.”
Sprouts are a bit like sprites, in that they’re all over the place, agile, and difficult to get a bead on. Whether it’s pro-sprout or anti-sprout, solid data is tough to pin down. For one, “sprouts” is an incredibly non-specific term. Sprouts can come from legumes, grains, vegetables, and nuts. In other words, if it’s got a seed, you can get a sprout from it. And so you can’t look up the nutritional data for “sprouts,” because that would be like looking up the nutritional data for “meat.” It could be almost anything.
What we need to analyze, then, is the sprouting process. Does it do anything bad? Good? Is it neutral?
Sprouting tends to convert some of a seed’s sugar into vitamin C (to act as an antioxidant for the plant). That’s good. We no longer make vitamin C ourselves, so we need an exogenous source. Not a lot, but some.
Sprouting tends to reduce phytic acid (but not saponin content).
What about specific sprouts? I dug up a few citations:
Sunflower sprouts have anti-glycative and antioxidant effects, due to their elevated cynarin content.
Broccoli sprouts sound great, particularly for type 2 diabetics. In a double-blind placebo-controlled trial, they reduced oxidized LDL (and improved the oxLDL/LDL level) and decreased triglycerides in diabetic patients. They also reduced insulin resistance in type 2 diabetics. And finally, they reduced oxidative stress in type 2 diabetics.
If you’re making your own, note that antioxidant levels wax and wane throughout the sprouting process, at least in broccoli sprouts. Sulforaphane, the potent antioxidant responsible for many of broccoli’s benefits, declines upon germination, then increases slowly until hitting its high point at 48 hours post-germination, after which it declines. But don’t worry; glucoraphanin, which converts into sulforaphane, increases during the first 12 hours, sharply drops, then rises again, reaching the highest levels at 72 hours post-germination. Of course, glucoraphanin requires the enzyme myrosinase for conversion, but broccoli sprouts are particularly high in myrosinase, so you’re ending up with plenty of sulforaphane either way.
I see no reason why sprouted celery seeds, broccoli seeds, radish seeds, or lettuce seeds wouldn’t be perfectly Primal. Lentil, oat, or bean sprouts? Probably not technically, although even those would be far less problematic (bean sprouts go great with spicy Thai food on a hot day). Just be aware that they have been linked to international E. coli and salmonella outbreaks, probably due to the warm, moist growing conditions required for sprouts.
Verdict: Primal, depending on the starter seed.
Agave nectar is a favorite whipping child of the Primal set, but we should substantiate our claims, don’t you think? We need to justify those welts, especially since a few of you guys were wondering (hoping?) about its place in the Primal Blueprint.
Agave nectar is insanely high in fructose. Of the sugar present, up to 92% of it is pure, unadulterated fructose. That’s considerably more than table sugar, most honey, and even high-fructose corn syrup. If we want to avoid fructose, agave nectar must also be avoided.
However, the recent honey post shows that not all sugar behaves the same. Honey — a “natural product” — contains a wide range of bee-based phenolic compounds that appear to render its sugar content less harmful than, say, a dose of HFCS with the same amount of fructose. Since agave nectar is also “natural” (it’s gotta be, with “nectar” and an exotic word like “agave” in the name), could it too be different than other sugars. No. A recent study found that while stuff like honey, molasses, and maple syrup all contain significant amounts of antioxidants that potentially mitigate the metabolic damage wrought by the sugar therein, agave nectar — along with refined sugar and corn syrup — has almost none. Even raw cane sugar beat agave nectar out in the antioxidant category.
Verdict: Not Primal.
Many of your favorite darkest chocolates contain soy lecithin as an emulsifier, promoting smoothness and a luscious mouthfeel (whatever that means). Dark chocolate? Great. Anything with “soy” in it? Bad, or so we have been conditioned to react. But is it?
In a previous Dear Mark, I made the case that a little soy lecithin in your chocolate is nothing to worry about, even going so far as to mention the choline content as a benefit. Since the influx of questions on soy lecithin, however, I’ve revisited my stance and found some new evidence. It seems that across a whole host of soy products, soy lecithin was the most estrogenic (though estrogenic activity was found in almost all foods tested, even non-soy ones). And in “frozen rat spermatozoa,” soy lecithin — but not egg yolk (another source of choline) — interfered with mitochondrial function. Contrary to my previous assertion that soy lecithin cannot trigger soy allergy in allergic people, another study found that soy lecithin could contain “hidden soy allergens.”
I would caution any soy-sensitive individuals to stay away from soy lecithin, just to be safe. If you’re worried about missing out on a great dark chocolate, plenty of legit brands contain no soy whatsoever. Just check your labels. I would also suggest that any chocolate eaters with unexplained unpleasant symptoms make sure the chocolate they favor contains no soy lecithin, and try switching to a soy-free brand for a month. If you feel better, you might implement soy lecithin avoidance as a general rule.
Everyone else, don’t shy away from good dark chocolate. Just don’t eat it too often, supplement with soy lecithin, nor feed your baby dark chocolate.
Verdict: Not Primal, but small amounts in occasional chocolate shouldn’t be too bad for most people.
