Drinking calcium-rich milk strengthens your bones — but it’s not the only thing you can do for a strong and healthy skeleton. Dr. Jen Gunter digs deep into the three layers of bone to explain why they weaken as we age and shares what you can do to maintain a healthy frame for years to come.

Think you know how your body works? Think again! Dr. Jen Gunter is here to shake up everything you thought you knew — from how much water you need to drink to how often you need to poop and everything in between. This TED original series will tell you the truth about what’s *really* going on inside you. (Made possible with the support of Oura)

Transcriber:

You might believe that drinking milk,

with all its calcium and vitamin D,

is the one thing you need
for strong and healthy bones.

And it’s a really nice message
that sold a lot of milk over the years,

but it’s just not scientifically accurate.

(Music)

[Body Stuff with Dr. Jen Gunter]

When we focus on milk,
we lose the bigger picture of bone health.

So let’s start at the beginning.

Adults have 206 bones

that form the main part
of the skeletal system.

They’re the support structure or cage
that protects our organs,

but they do so much more.

They work with our muscles
to move our bodies,

they store important minerals,

they produce hormones,

and they even make our blood.

Many people think of a Halloween skeleton
when they imagine bone,

but that only gives us
a one-dimensional view.

Bone actually has three layers.

On the outside, there’s the periosteum,

a tough membrane that covers and protects.

Next, there’s a thick layer
of compact bone,

the white, hard, smooth part
that most people are familiar with.

But inside, there is spongy
or trabecular bone,

and an inner core filled with bone marrow,

which contains stem cells that make blood

and are constantly dividing.

Most people understand that our bones grow
when we’re kids and adolescents.

We reach our peak bone mass in our 20s.

What many people don’t know
is even after we stop growing,

we are constantly removing old bone

and replacing it with new.

One estimate is enough bone
is removed and replaced

that a new skeleton
is made every 10 years.

After we reach our peak bone mass,

bone removal starts
to outpace replacement.

This can eventually affect
the integrity of the bone

and it lowers the bone mass
or the amount of bone that we have.

The bone disease osteoporosis
is an extreme version of this process.

Bone loss outpaces replacement,

and combined with other changes,

this can lead to so much fragility

that even small bumps or falls
can create fractures.

Another cool fact about bones
is they store calcium,

so if intake is low,
meaning not enough in our diet,

the body draws calcium from the bone.

This can also contribute to bone loss,

so we need enough dietary calcium
to maintain our bone.

Vitamin D fits into the picture

because it helps our body absorb calcium.

When we think of calcium and vitamin D,

many of us picture a frosty glass of milk.

Milk is not the only good source
of calcium out there.

Humans are creative omnivores.

We can get calcium
from a lot of other sources —

yogurt and cheese, for example —

but also look for leafy greens
like spinach and kale,

cruciferous vegetables
like broccoli and cabbage,

and proteins like tofu,
nuts, beans, eggs and fish.

Fortified cereals and orange juice
are also good too,

and chia seeds.

And vitamin D
is plentiful in fatty fishes,

and our skin makes it from the sun.

However, some people may need supplements.

Another important factor
for bone health is exercise.

Mechanical loading stimulates
the cells that build bone

and muscles pulling on the bone
may do this as well.

In fact, any activity
that puts stress on your bones,

like walking, jogging,
dancing, racket sports,

even strength training like doing weights,

stimulates extra deposits of calcium

and growth of new bone.

In addition, stronger
muscles can help with balance.

And one of the best ways
to prevent a hip fracture?

Reducing falls with better balance.

If milk is your thing,
that’s completely OK,

but don’t forget

that bone health
is so much more than just milk.

    But there is no any natural vitamin D in milk. And calcium — in orange juice. Are these series for americans only?

  10. Krista Heikkala

    Yes you can get calcium from other places than milk products. BUT they didn’t mention any portion sizes. To get the same amount of calcium than from a cup (=2.4 dl) of milk you would have to consume: 300 g of spinach / 1,5 dl of almonds / 5 eggs / 2-3 oranges / 3 tbls of tahini / 5 dl of soya beans / 150g of salmon / 1 kg of broccoli. An adult needs 800 mg of calsium a day, which is about 3-4 portions daily. Yes, you can live with out drinking milk, but getting enough of calsium with out any milkproducts is hard.

    Spinach is NOT a good source of calcium. It has a lot, but it is not nutritionally available. Kale and Collards do have a lot of nutritionally available calcium.

    I know it’s frowned upon by a lot of people nowadays, but as long as I can still keep drinking my milk I’m all good.

    *Prayers and well-wishes are also very much appreciated. 😇*

    Off-topic, I know… I hope you understand the desperation.  I know some people need more help than me and my family but I do hope that does not invalidate my cry for help. 🙏

    Things are getting worse here. We don’t have stimulus checks or anything like USA. So I’m just really doing whatever I can to put food on the table. *We may not be killed by the virus but the situation is surely slowly killing us.*💔 

    *Peace be with you. GOD bless. 🙏❤*

    Wouldn’t strengthening your bones via activity be increases its MASS? So we don’t stay the same MASS, if we lose calcium overtime from inactivity

    You will need 2kg raw broccoli for a daily intake of calcium, or 1 kg of spinach wich contains oxalic acid that binds to both iron and calcium and make crystals in your body. 100 gram of cheese is what you need for a daily intake.

Robinhood is looking to catch up to the Apple Card. The consumer trading service announced its long-anticipated credit card, the Gold Card, to compete with Apple’s offering. Open only to subscribers of Robinhood Gold, the Gold Card features 3% cash back on all purchases and the ability for users to transfer cash earned to their brokerage accounts.

As Apple expands into more fintech services, Robinhood is racing to eat a portion of the same market — users who prefer a tech-first option over a traditional banking relationship.
