AGEs impact your age
How sugar rusts your body internally
THIS WEEK’S CODE:
💡 The focus → Sugar binds to protein to form damaging compounds called AGEs.
⚠️ The impact → AGEs stiffen tissues, accelerate aging, and increase inflammation.
✅ The fix → Steady blood sugar and use low-AGE cooking methods.

IN PARTNERSHIP WITH…

This week’s partner spotlight is a powerful recovery combo.
Heavenly Heat Saunas builds some of the cleanest, lowest-EMF infrared saunas on the market - handcrafted without glue or hidden plywood, and Carnivore Snax, the meat snack of choice for biohackers, brings the cleanest possible fuel to match, made from 100% grass-fed meat and Redmond Real Salt with zero fillers, sugar, or seed oils.
FOR ALL OF DECEMBER, when you buy a Heavenly Heat Sauna through our partnership link, you’ll receive a $750 Carnivore Snax gift card.
Together, they’re a duo built for people who take detox, recovery, and long-term health seriously.
Your body is running a gentle version of a cooking reaction every hour of the day.
A similar reaction to the browning we see in cooking also happens inside the body, just far more slowly and as a normal metabolic process. It’s called glycation, and it begins when sugar attaches to your proteins and forms Advanced glycation end products (AGEs).
These molecules gradually settle into the collagen of your skin, the lining of your arteries, and the connective tissue in your joints.
Over time, they can make those tissues a little less flexible and a little less resilient, even when the rest of your habits look healthy on the surface.

How AGEs damage your body
Once glucose binds to a protein, the structure of that protein changes permanently, a process driven by the Maillard reaction.
These crosslinks stiffen arteries, cloud eye lenses, weaken kidney filtration, and disrupt normal repair.
AGEs also trigger inflammation and oxidative stress, which accelerates cellular aging.
High-heat cooking adds another layer because frying, grilling, and roasting can increase AGE content in food by 10x or more, as shown in research on dietary AGE formation.
Modern life supercharges glycation
Today’s eating patterns create the perfect environment for AGEs to form quickly.
Big glucose swings from refined carbs dramatically increase glycation, where glucose variability increases AGE formation even in non-diabetics.
Externally, grilled and fried foods carry high levels of dietary AGEs that the body absorbs. In the skin, AGEs crosslink collagen, a mechanism documented in research on skin aging and collagen stiffening.
Over time, they contribute to the progression of diabetes, cardiovascular disease, and neurodegenerative disorders - all supported by research connecting AGEs to chronic disease development.

Glycation lowering habits
Glycation slows down quickly when blood glucose becomes more stable.
Pairing carbs with protein, fibre, or healthy fats reduces spikes, a principle supported by studies on postprandial glucose control.
Cooking methods matter too: steaming, boiling, stewing, and poaching produce far fewer AGEs than high-heat methods according to cooking-method research.
Antioxidant-rich foods also blunt the oxidative stress AGEs create, effectively reducing glycoxidation.
Even a short walk after meals reduces blood glucose, with studies showing 10 minutes of movement lowers post-meal glucose levels.

Take note of what goes on in the background
One of the clearest signs of aging is the gradual loss of flexibility, not just in movement, but in how the body adapts to stress.
AGEs accelerate this decline by making tissues rigid and slow to repair. Lowering glycation protects the elasticity that keeps you energetic, mentally sharp, and physically responsive.
You start feeling the difference long before any blood test reflects it.
When your tissues stay flexible, your life does too. It’s less about turning back the clock and more about removing what makes time feel heavier than it should.

TLDR TRIO
📈 You slow the chemical processes that stiffen tissues and accelerate aging.
✅ Your skin, vessels, and organs stay more resilient and youthful.
⌛ Applying these habits consistently can help you see measurable improvements in glucose stability and inflammation over time.
