Hi there, how's it going?
Be honest, when was the last time you thought about zinc?
Not zinc roofing, not zinc sunscreen, I'm talking about zinc, the mineral that's quietly
running the show behind the scenes of your immune system.
Today, we're going to be diving deep into why this underrated nutrient deserves a spot
in your supplement stack, and maybe even on your dinner plate.
Let's roll.
Okay.
What even is zinc?
Zinc is a trace mineral, so that means your body doesn't need heaps of it, but the little
bit it does need is super important.
Think of zinc as the mechanic in the background, making sure all the gears of your immune system,
hormones, skin, and even taste buds are running smoothly.
You won't get an energy rush from zinc like you do from caffeine.
It doesn't get the high black ashwagandha, but without it, you're leaving a lot on the
table.
So let's start with the biggie, your immune system.
Zinc is a total legend here.
Why?
It helps your body make and activate T cells.
Those are the elite soldiers that find and destroy viruses in bacteria.
It shortens the duration of colds like science backed little.
A meta-analysis, that's just science speak for a study of studies, found that taking zinc
at the first sign of cold symptoms could cut down your sick days by around 33%.
That's not bad for a tiny mineral, yeah?
Now is it a magic shield?
No.
But if you're getting sick of getting sick or you work in retail, have kids, or just interact
with other humans on a daily basis, zinc might just be your immune system bestie.
All right, New Zealand, what's happening?
Let's bring it local.
Here in New Zealand studies show that about one in five adult kiwis may not be getting enough
zinc from their diets.
Those especially at risk are older adults, vegans and vegetarians, people who like to drink
a little bit too much alcohol, athletes with high sweat loss, and those who mostly eat processed
or low zinc foods.
Why?
Because zinc's found in foods like red meat, shellfish, seeds, nuts and legumes.
Not exactly the staple of every kiwi diet, especially if you're just living on takeaways
and then up and go.
Now zinc has some other superpowers.
It's not just about the sniffles.
There are other areas where this mineral shines.
Acne and skin health, zinc helps with inflammation, wound healing and even hormonal regulation.
So it's often used in skincare for acne prone skin.
At one replace your skincare routine, but it can help reduce those surprise breakouts.
Also in mood and mental health, low zinc is linked with increased anxiety and depression.
It's for sure not the cure, but it might be part of the puzzle, especially if your diet
is being met.
Homones for the fellas, zinc is crucial for testosterone production and low zinc levels
have been associated with reduced fertility in men.
And we got wound healing.
Either way, wonder why zinc is in so many appointments is because it speeds up skin repair
and reduces inflammation.
Great for scrapes, cuts or just surviving your latest DIY project.
So how much do you need?
Most adults need about 11 milligrams a day for men and 8 milligrams a day for women.
Sometimes of stress, sickness or pregnancy, those needs go up, but here's the kicker.
Too much zinc can definitely backfire.
High doses long term can mess with your copper absorption, suppress your immunity and even
cause gut issues.
So don't go zinc crazy.
Follow the dosage on the label or better yet, get your blood levels checked if you're unsure.
Alright, so you can totally get zinc from food.
Here are some all star sources.
Number one, oysters, the king of zinc, like five times the daily amount in just one or
two of these bad boys.
Of course, beef and lamb, number two, three legumes, so lentils, chickpeas, beans, and
always room to soak them first as well.
Pumpkin seeds, cashews and cheese.
And if you're not eating these food often or you're in one of the at risk groups we mentioned
earlier, zinc supplement can definitely fill the gaps.
So what type of zinc should I take?
If you're scanning supplement labels, here's a quick breakdown.
Zinc, there's zinc piccolon late.
Excuse the pronunciation of that.
So that great absorption, zinc centrate, as easy on the stomach, zinc gluconate, commonly
used for cold lozengears, and zinc oxide.
So this one's generally not as well absorbed as the others.
Try and take it with food and try and separate it from iron or calcium supplements if you're
stacking them.
Alright, my final thoughts.
Is zinc worth it?
If you get sick often, feel run down, have stomach skin issues, eat a mostly plain plant-based
diet or just want to give your immune system a bit more backup.
Then yes, definitely zinc could be a quiet game changer.
It's not flashy, it's not trendy, but it's definitely powerful.
A little zinc goes a long way.
And when the winter bugs start flying around, you'll be glad you topped up.
In closing, alright, so that is it for today.
The zinc might not get all the glory, but now you know it deserves a spot in your wellness
toolkit.
If you found this episode helpful, think it to a mate who's always battling colds or who
needs an excuse to eat more oysters.
Stay well and remember, sometimes it's the simple stuff like minerals, getting a decent
night's sleep and eating a clean, healthy meal that keeps us feeling our best.
Until next time, stay curious, stay consistent, and remember, take your vitamins.
