Pretty...aging |
“It’s only 30 minutes, and then
we’ll hit the tapas-and-tequila happy hour in the lobby,” my coworker said.
We were at a nutrition conference
where, after sitting through eight hours’ worth of lectures, my brain was fried.
I just wanted to go to my room and chill out before the party.
But no, my coworker insisted on
this 4:30 p.m. seminar, cleverly titled “How AGE-ing can Destroy Your Life.”
Well, duh, of course growing older sucks if you don’t take care of yourself, I
reasoned. I didn’t need to hear a lecture about it.
I soon understood the lecturer’s
clever wording: He was talking about an entirely different sort of aging that
can wreak havoc on every system in your body.
Protein and Maple Syrup: Not a Good
Combo
I wearily sat down for this
presentation (“It had better be good!” I snapped at my coworker as I fumbled
open a dark chocolate bar) and watched as this doctor demonstrated how, in a
maze-like structure, oyster-looking proteins slithered around in your body.
“This is what proteins do,” he
explained. “They form antibodies, enzymes, and other important things.” I
really didn’t care, and those oysters were making me hungry.
Then he really got my attention.
The doctor grabbed a measuring cup
full of maple syrup and pored it on to the proteins. Unsurprisingly, stickiness
hindered those proteins. They slowed down and eventually became stuck. It was
like driving down the freeway 80 miles an hour and suddenly getting stuck in
Los Angeles rush-hour traffic. Everything came to a halt.
“That’s what happens when you eat
too much sugar,” he explains. “Sugar literally ‘gums’ up those proteins, making
them inefficient to do their jobs. It’s called glycation, and advanced
glycation end products – with the appropriate acronym AGEs – are the end
result.”
Fascinating, I thought, promising
myself I would research this more later. I had mentally checked out; my mind
was on gluten-free beef tacos for dinner.
What are Glycation and AGEs?
I followed up on my
self-promise and researched AGEs a few days after the conference. Thankfully,
my friend Dr. Jonny Bowden talks about glycation and AGEs in his books. Jonny
has this rare ability to make complex science really simple without dumbing it
down.
Glycation occurs when sugar
sticks to places it doesn’t belong – namely, proteins – making these places
sticky and inefficient. Jonny calls glycation “one of the Four Horsemen of
Aging” that contributes to nearly every disease on the planet.
When these proteins become glycated
– in other words, when the proteins become “stickied up” – molecules called
advanced glycation end products (AGEs) result. As these hard-working proteins
become more and more coated with this sticky syrup, they can’t get through the
smaller blood vessels and other areas that need blood flow.
Understandably, this slow-down
effect wreaks havoc on your entire body. AGEs inhibit blood flow. They damage your
arteries, increasing your risk for stroke, heart disease, and other
complications. They destroy your immune system. And appropriate for the
acronym, they age you.
The
Ugly Repercussions of AGE-ing
I’m willing to bet you have someone
in your family with diabetes. Over time, if they don't take care of themselves,
potentially fatal complications occur like neuropathy, kidney problems, and a
weakened immune system. Tragically, they may need to have a limb amputated. Not
a pretty situation.
Diabetes provides a classic example
of glycation. This makes sense considering diabetes involves too much sugar in
your blood (increasing risk for sticky proteins) and impaired circulation.
Among their problems, researchers found AGEs contribute to diabetic nephropathy and
retinopathy.
It isn’t just diabetes. AGEs “accumulate to
high levels in tissues in age-related chronic diseases,” one study
found. Among those diseases, one study connected AGEs with Alzheimer’s
development.
No organ becomes spared for the
devastating effects of AGEs: Your vascular system but also your brain, your
nervous system, and your bones all take a hit. AGEs are equal-opportunity
offenders that don’t discriminate in any organ.
Studies show oxidative stress can increase AGEs. Numerous
things trigger free radicals that create oxidative stress, some within your
control and others not so much. (More on that in a minute.) A chicken-or-egg
scenario results. Glycation creates oxidative damage, churning out more free
radicals that eventually amp up more AGEs.
AGEs can also increase chronic
inflammation, an athlete’s worst nightmare. Achy joints, soreness, and fatigue
are among inflammation’s many game-wreaking symptoms.
So you get it: AGEs are those big
bad wolves that create acute and chronic problems, and you want to do
everything possible to prevent them from forming. What can you do to minimize
AGEs? Glad you asked.
Strategy #1: Minimize the Fried
Stuff
Ah bacon, let me count the ways I
love you. Except… Well, I knew sugar contributed to glycation, but fat!? No,
not my beloved grass-fed beef and nitrate-free bacon.
Actually, it depends.
“When you cook foods at really high
temperatures like those needs for frying, it results in what’s called a
‘browning’ effect, which is simply another term for glycation,” Bowden says.
“You’re basically eating glycated proteins.”
He goes on to say high-heat cooked
foods “are virtual glycation factories [where you ingest] AGEs, which are
basically the end result of glycation [emphasis his].”
So it isn’t the meat itself but how
you cook it. If you’re eating restaurant-cooked bacon, you’re probably increasing
your AGEs load.
One study looked at how various
cooked foods can create AGEs. “The amount of AGEs present in all food categories
was related to cooking temperature, length of cooking time, and presence of
moisture,” researchers concluded. Broiling and frying yielded the highest levels of
AGEs. Good to know.
We live in the real world, and
occasionally you’re going to eat restaurant bacon or fried eggs or whatever. Do
it infrequently and more importantly, eat your veggies to reduce that glycation
load. (More in a minute.)
Strategy #2: Nix This Type of
Sugar
You probably know my most effective
strategy to reduce your risk for AGEs: Pull the sugar. When you don’t surge
your bloodstream with sticky sugar, you don’t glycate those crucial proteins. Duh.
Well… Yes and no.
As a heavy lifter or athlete, your
muscle cells have become really good at soaking up sugar as glucose, which gets
stored as glycogen for back-up fuel. You can get away with eating the
occasional sweet without creating major metabolic damage.
What your muscle cells don’t
soak up is fructose, an especially harmful sugar that goes straight to your
liver and eventually converts to triglycerides (fat). Bowden says fructose is seven
times more likely to form AGEs than glucose.
You would think, based on strategy
#1, meat eaters would have higher levels of AGEs. I mean, even the purest
carnivore who swears by grass-fed everything will occasionally eat restaurant bacon
or some sort of fried meat, increasing AGEs formation.
Think again. One study found
vegetarians had higher
levels of AGEs than meat eaters. How could that be?
Well, there are two types of AGEs:
plasma AGEs (formed inside your body) and endogenous AGEs (formed outside your
body). Turns out vegetarians had higher levels of endogenous AGEs.
What’s more, researchers found on
average vegetarians ate more high-fructose vegetables and fruits than meat
eaters; vegans ate over twice the amount of high-fructose fruit.
Beginning to see a pattern here?
The occasional apple or other fructose-rich food isn’t going to create
problems, but when you nosh on high-fructose foods all day in lieu of
high-quality protein and healthy fats, you increase your AGEs risk.
The take-home is to keep all
sugars – even the healthy ones in fruit – in check. If you’re vegan or
vegetarian, focus on plant foods rich in protein and fat like avocado, nuts,
nut butters, and seeds.
Strategy #3: Bump up
Antioxidant-Rich Plant Foods
I’m a meat girl. Give me a good
grass-fed steak and I’m an easy date.
That said, I’m also about balancing
meat with antioxidant-rich plant foods. Namely, I load my plate with tons of
leafy and cruciferous veggies. I throw berries and avocado into my protein
shake. Quinoa and sweet potatoes are my starchy-carb best friends.
“Animal-derived foods that are high
in fat and protein are generally AGE-rich and prone to new AGE formation during
cooking,” one study concluded. “In contrast, carbohydrate-rich foods such as
vegetables, fruits, whole grains, and milk contain
relatively few AGEs, even after cooking.”
Simple: Cook your (high-quality)
meat correctly and amp up your plant foods.
Besides, there are numerous other
benefits to eating vegetables and other plant foods. Many of them are
anti-inflammatory, boost immunity, and add variety to your meals. When you
combine protein and healthy fats in meat with fiber, nutrients, and
antioxidants in plant-based foods, you get a win-win meal.
Strategy #4: Exercise Smarter
I couldn’t find any studies that
show exercise directly impact AGEs, but indirectly it can provide several
benefits including:
·
Normalizing inflammation levels in
your body – remember, inflammation and AGEs go hand in hand
·
Helping your body better metabolize
sugar so it doesn’t “gum up” those important proteins
·
Reducing your risk for diabetes,
cardiovascular disease, and other problems
Studies show exercise can increase
oxidative stress, wreaking havoc on your
body. A couple of ideas to reduce that damage:
·
Don’t over-train, which can
increase oxidative stress and keep your stress hormone cortisol ramped up when
it should be tapering down.
·
Make sure you’re eating a wide
variety of colorful antioxidant-rich foods to reduce exercise-related oxidative
stress.
·
Consider an antioxidant supplement.
Nutrients like carnosine, resveratrol, and curcumin (the active ingredient in
turmeric) can help normalize inflammation and reduce free radical damage.
Strategy #5: Prioritize
Recovery
In the fitness world, we love to
talk about how heavy we lift and how hard we work. Recovery and repair just
sound like we’re slacking, yet as I’ve said before, they contribute more
to your overall fitness goals than actually working out.
Over-training can increase AGEs. So
can chronic stress and not getting enough sleep. One study found non-diabetic
people with obstructive sleep apnea had increased levels
of AGEs.
Even if you don’t suffer sleeping
disorders, not getting eight hours of high-quality, uninterrupted shut-eye
every night can skyrocket aging, increasing inflammation and sending you down
the path to disease.
