It appears difficult to meet the Recommended Dietary Allowance (RDA) for calcium while eating most versions of the paleo diet. That’s because they don’t include milk products. The Linus Pauling Institute at Oregon State University has a review of calcium as related to nutrition and health, last updated in late 2010. They say that few Americans hit their recommended daily calcium goal.
I see lots of little old ladies with hip and other fractures related to osteoporosis. Trust me, you don’t want to go there. It’s difficult to reverse osteoporosis, an insidious process that’s been going on for decades before the fracture.
Osteoporosis may be related to years of inadequate calcium consumption. Adequate vitamin D is an important part of the equation, too. Blood calcium levels are strictly regulated, and if they’re too low, calcium is pulled from the bones to fill the blood’s tank.
Broccoli and bok choy are fair sources of calcium, but pale in comparison to milk. Bok choy isn’t a part of my diet; I’m not even sure I’ve ever had it. Below is a video on bok choy cooking. Looks simple enough. I need to look into kale, too.
Many paleophiles promote bone broth, but I haven’t figured out why yet. Is it high in calcium? (Hat tip to Wendy Schwartz for the word “paleophile”.)
A can of sardines looks like a good source of calcium: 350 mg or 35% Daily Value.
Can you help me worry less about calcium deficiency?
