Time for an interesting thought experiment... page 2

I always go over the RDA for Vitamin C and A. Calcium and Iron I always seem to be under since I don't drink milk. I can reach the RDA if eat about 200 g of liver in a day but it's not something I do on a daily basis.

Is it a big deal if i don't meat the calcium and iron RDA? thoughts?

Calcium is probably a bigger concern than iron. But two great sources of calcium for those who don't drink milk are actually very primal. Deep green veggies and shrimp are both great sources of calcium as far as my knowledge on the subject goes.

Possibly. If you're a menstruating female, then you're very possibly losing iron on a regular basis. I type medical reports for oncologists and hematologists, and I see a lot of reports for women who are in their active child bearing years who are anemic because of heavy blood flow every month.

When you're young and active, low amounts of calcium may not be an issue, either. As women age and our bodies go through menopause, the calcium in our bones starts to decrease. If you are not actively supplementing with calcium or getting lots of calcium in your diet and participating in weightbearing exercise on a daily basis, your bones could become weaker than you would want them to be.

Conversely, the iron isn't as important as women age and stop regular blood flow every month.

I guess I'm okay then. I lift weights 3 x a week and have doing this for the last 8 years. I'm only 30. I have never broken anything in my life so that sure is a good sign. I actually started eating beef liver around the time of the month for the extra iron.

The problem usually isn't too little calcium but malfunction of the calcium metabolism due to other deficiencies. Vitamins D, A and K are key here, along with magnesium and zinc. Vit D, K, Mg and Zn are often deficient. Sun, fermented food and seafood are the key. Vitamin D is so important here that the common paleo recommendations to supplement it at much greater rates than the RDA need to be counterbalanced by monitoring of calcium as it can cause an overload

Just a thought - but way back in the day......as in caveman times........the food that was ingested would have to have been more nutrient dense than today??????? wouldn't it ????? so todays foods might just be totally different ???
just wondring !

This is very likely the case. It doesn't mean that we can't, or shouldn't, be on the lookout for a way to get our entire RDA of nutrients daily. In fact, it probably means that this is even MORE important.

Isn't
Step 1: acquire beef liver
Step 2: Fill in the gaps
Step 3: Profit??

My friend did this through most of her pregnancy and for the year that she breast fed. She also took prenatal vitamins, but tried to get her rda of micro nutrients outside of the vitamins. She is primal... she's not on this forum, but she is the one who introduced me to MDA She said it could be very challenging. I don't think she was too strict on the calories though.... she's one of those people who can eat whatever she wants and not gain an ounce anyway though... lucky girl

So are you saying that a calcium supplement is also needed for proper absorption of vitamin d. Maybe I'm not understanding what one truly needs in terms of supplements in order to be as healthy as possible. I thought paleo brings you as close to being healthy without needing too many vitamins from pills.
