Norman, do you have a favourite calcium source?
You mean apart from chewing on chalk?
That's your favorite way of getting calcium?
No, no. My favorite way of getting calcium is Greek yogurt.
Oh, same. Actually, no, my favorite way of getting calcium is ice cream, but I subsist mostly on Greek yogurt in the day to day. And I, yeah, big agree on that one.
Yeah, that's my biohack is Greek yogurt. And I found this amazing Greek yogurt, but I can't advertise it on air. So we'll not talk about that.
We'll have to compare brands after the show when we're not recording and see if we have the same preferred Greek yogurt vendor. Mine isn't a brand. Do you make your own? Have you ever made your own yogurt?
I have many, many years ago and it wasn't a big success. Tasted revolting. You know, you add the culture to milk and you get it going.
I've made it before. I actually, it did turn out quite well if I do say so myself, but the cost and the effort, it wasn't much different than just going to my local grocery store and buying a kilo of Greek yogurt from there.
I think that's right.
Anyway, calcium is the topic of today's What's That Rash?
The show where we answer the health questions that everybody's asking.
Norman, so many people want us to talk about calcium supplementation. Seven different question askers asking about this today.
What are the calcium needs for different age groups?
That's our entire audience. What are you going on about? Exactly. Every single one of What's Up Russia's listeners is desperate to know about calcium supplementation. Kay, Kasia and Ashley are asking about calcium supplements in general. Are they helpful? What's with the different types of calcium supplements? Louise, Paula, Alison and Susan are asking about calcium supplements and the risk of calcium buildup in the arteries. So Paula shared her attempts at getting more calcium in her diet last By keeping a food diary and wants to know if you can overdo calcium, Paula says, mostly I get between 600 and 900 milligrams from my diet, but on one latte-fueled deadline day, I hit a whopping 3,600 milligrams from dietary intake alone.
So my question is this, is too much calcium from food sources as bad for you as too much calcium from supplements? Paula says, I'm hearing a lot of conflicting advice about calcium. I recently listened to the ice cream episode of Science Friction, and it turns out I'm not the only one utterly perplexed by dairy and calcium requirements. So yeah, lots of calcium questions today, Norman.
There are, and it's an important issue. We need calcium.
We do.
I will actually add a little asterisk on the Science Friction episode on ice cream, which Paula mentions. I have to say, if you want to listen to it, it's from a 2025 series called Cooked in the Science Friction feed. And while you are there, hit follow because Shelby Traynor, our producer for What's That Rash, actually has a brand new Science Friction series that's going to drop in that same feed in just a couple of weeks. And it's all about quantum computing. Yes, don't miss that. But yeah, the people yearn for information about calcium, Norman.
They do. You know, I throw in a remark, we need calcium. So calcium is in our bones, but we actually need calcium for the healthy functioning of our nervous system and indeed our heart. And calcium in our blood needs to be finely tuned in order for that to happen efficiently and not aberrantly. It is pretty well controlled, but the questions here are really when you have too much calcium, does it get deposited in places where it's not meant to be?
Yeah, I think the questions here are basically around how much do I need and how do I get it and what happens if I overdo it?
