Can someone please explain me why there are (so many) people eating SAD with little to no variation in their diet AND don't have any nutrient deficiencies showing up from their blood test
there are (so many) people eating paleo + taking supplements to deal with (a truckload) of deficiencies. I really don't get it.
I can eat loads of bread, pasta, fries, junk-food, a few vegetables and highly processed meats and have a perfect blood test.
BUT when I eat whole foods, add in a wide variety of vegetables and meat and healthy fats etc., I suddenly have to incorporate offal to make sure I get enough Vitamin [X], I have to add [insert food] to get enough Vitamin [X], I should take a heap of Vitamin D pills cause suddenly I'm in lack of that too, etc. while I never ate these foods on the SAD and had none of these Vitamin deficiencies.
Isn't this supposed to be the other way around? What kind of sorcery is this?
A few things.
1) A lot of the things you mention have vitamins added (fortified cereals for example). This is BECAUSE they're so deficient after processing. So you're still taking the vitamins, just in the foods vs in pills.
2) You assume your blood tests are "perfect". Pefect in respect to what? The regular SAD population? In a nation of the blind, being blind is consistent with the population, and you could be considered "perfect" if you were blind. But I think you'll agree, life is better if you can see... :)
3) Specific to Vitamin D. My understanding is people are deficient on SAD as well as on Paleo diets. You need more, period. You just may never have thought about it before.
1) People turn to paleo because they realize they are nutrient deficient
2) People eating paleo are more conscious of possible deficiencies, as they're constantly reading about K2, Magnesium, Selenium, etc.
3) People on the SAD do have nutrient deficiencies but don't connect what they're eating to their health in the same way, or are not as health-conscious and never realize that their symptoms (e.g. constant stuffiness, getting sick in the winter all the time) are related to nutrient deficiencies
And what do you think you're deficient in that you weren't on the SAD?
Iodine and K2 are the biggies I see in my own patients. I also see a lot of B vitamin issues because many changing into paleo have pre existing leaky guts. They cant assimilate the good nutrients from foods for a variety of issues that need to be cleared up first.
A lot of processed foods are fortified. In my past diet, I was drinking soy milk (almost always fortified), bread (if you buy from the regular store, always fortified)...even soda has some added vitamins.
However, personally I've never had a vitamin deficiency on paleo. What kinds are you having?
I believe people eating SAD definitely have nutrient deficiencies.
For example, with so many women developing osteoporosis it seems apparent that they are not absorbing enough calcium and minerals from their diet. They might be eating enough calcium and minerals but there is a good chance that the phytic acid in their SAD diet is blocking the absorption of these nutrients.
So a teenager eats only Chicken McNuggets for 15 years before she collapses. Seems like an anecdote that suggests that the younger you are, the more resilient you are. Real nutrient deficiencies are hard to come by in a reasonably modern diet, so while SAD folks aren't dropping like flies on that diet, that doesn't mean that their diets are optimal.
OTOH, you have paleo folks who are all about achieving optimum diets. Sometimes this tilts a little too far to something akin to the so-called orthorexia.
I think most folks are in the middle. I think it's better to get nutrients from food, but that means that you do need to eat the foods that contain them! Grass-fed beef is great, but if all you eat is flank steak or burger, you're missing out on an opportunity to get valuable nutrients (known and unknown).
Supplements seem like a great shortcut to optimum health, but I think in many cases it's a crap-shoot (I suspect we will see a dark side to all of this artificial boosting of serum vitamin D levels for example).
I think after the near miraculous changes that happen when eating in a Paleo/Primal non-SAD fashion, ppl realize they may be able to get to "optimum" with some supplementation of nutrients. Our food is deficient now in some minerals b/c the soil is deficient. Also, years of SAD may have permanently damaged the intestinal mucosa and antibiotics may have permanently changed the intestinal biota and therefore ppl can't absorb enough nutrients. In that case, supplementation may do the trick.
The Paleos that truly "hack", i.e. (most of the members of this site), are going to be the ones that are trying to address specific needs, maybe it's sort of a "next level" between going "Ancestral" to going "Optimal" (The difference between say, "Neanderthin" or the "Paleo Solution", and the "Perfect Health Diet" or "Archevore").
However, there are many Paleos out there that do not augment their diet at all and are completely, utterly healthy. In fact, I would venture to say that most "hacking" (with exceptions for weightloss, athletics, and depression or other serious illnesses) is quite minimal impact on someone who already has their diet pretty much dialed in...
If you are actually getting tested and showing deficiencies in your diet, as opposed to when you ate a standard western style diet, I would assume a combination of one or more of the following...
Eating tons of synthetically fortified foods makes sure the "masses" won't drop over from undernourishment. But chances are, you are doing things right - you just aren't getting the surplus of your calories from foods that have had a chemical grab-bag added to their roster of ingredients just so the world doesn't shut down and die.
