Whereas the crust of a superbly grilled steak or the golden edges of a thin-crust pizza may be irresistible, routinely cooking with strategies like grilling, pan-frying and roasting comes with a hidden value. Chief amongst them is the manufacturing of superior glycation finish merchandise, compounds linked to quicker ageing.
On the flip facet, diet specialists level to water-based strategies, akin to steaming, boiling, poaching and simmering, as a simple strategy to protect vitamins and restrict AGE formation, making them a sensible selection for anti-aging cooking.
The pattern can be exhibiting up on TikTok, with creators spotlighting dishes like soups, curries and stews, emphasizing not solely their anti-aging advantages but in addition their skin-hydrating results, since these dishes are cooked with loads of moisture from water, broth and even coconut milk.

How Are AGEs Fashioned?
AGEs kind throughout cooking when sugars react with proteins or fat at excessive temperatures in a course of referred to as the Maillard response, the identical one that provides browned meals its taste and coloration.
“Dry warmth methods akin to frying, grilling, roasting, baking and barbecuing generate giant quantities of AGEs as a result of they contain excessive temperatures and low water content material, situations that strongly speed up browning and glycation,” stated registered dietitian and meals scientist Jennifer Pallian, describing glycation as a course of the place sugar molecules connect to proteins or fat within the physique with out enzymes, typically altering their construction and performance.
Why Are AGEs Thought of Dangerous?
“AGEs don’t simply sit quietly within the physique — they really bind to tissues and alter how they work,” stated registered dietitian nutritionist Melanie Murphy Richter. One clear instance is collagen: When AGEs connect to it, pores and skin, joints and blood vessels stiffen. “In addition they work together with a receptor fittingly referred to as RAGE (receptor for superior glycation finish merchandise), which triggers a cascade of irritation and oxidative stress.” Over time, that fixed stress weakens mitochondria, the energy-producing elements of our cells, and hastens what we expertise as ageing, akin to fatigue, slower restoration and lowered resilience.
AGEs may also speed up persistent illness. “In diabetes, they worsen insulin resistance by interfering with how glucose strikes into cells, they usually can injury the pancreatic beta cells that produce insulin,” Richter stated. “In heart problems, AGEs cross-link collagen in vessel partitions, making arteries inflexible and susceptible to plaque buildup.” Within the mind, AGEs add to oxidative stress and work together with proteins to create the inflammatory surroundings that contributes to Alzheimer’s.
Sofia Popov, microbiome scientist and founding father of GUTXY, a intestine wellness firm that provides personalised microbiome testing, provides that top ranges of AGEs within the weight loss plan may additionally disrupt the intestine. “They weaken the intestine’s protecting barrier, resulting in ‘leaky intestine,’ the place dangerous bacterial toxins escape into the blood.”
Plus, AGEs can upset the steadiness of intestine micro organism, reducing useful microbes that assist produce protecting short-chain fatty acids, whereas permitting much less useful strains linked to irritation and intestine injury to thrive. “These modifications set off persistent low-grade irritation, step by step overwhelming the physique’s pure defenses and accelerating ageing processes,” Popov stated.
How Water-Based mostly Strategies Maintain AGEs Low
Whereas cooking can destroy vitamins by breaking them down with warmth, water-based strategies use decrease temperatures — too low for the Maillard response to happen. That not solely helps restrict nutrient loss but in addition prevents the formation of dangerous compounds akin to AGEs. “Steaming helps protect vitamin C, B-complex nutritional vitamins and cancer-fighting compounds like glucosinolates, that are all heat-sensitive,” Popov stated.
Swapping dry-heat cooking strategies for water-based ones can lower circulating AGE ranges by as much as 50%. Popov notes that pan-fried eggs have about 10 instances greater than boiled eggs, stir-fried greens as much as 2.4 instances greater than their boiled counterparts, grilled rooster breast four to five times more than poached per serving, and french fries up to 90 times more than boiled potatoes per serving.
How A lot Is Too A lot?
There isn’t a universally accepted protected degree of dietary AGEs, as the danger relies on how a lot you absorb and the way successfully your physique clears them. “Solely a fraction of dietary AGEs is absorbed, and in wholesome individuals, roughly one-third of that absorbed quantity is excreted by the kidneys, whereas clearance can fall with kidney illness,” stated Kerri Louati, director of girls’s well being at LifeMD. “As a result of absorption, excretion, cooking strategies and the meals’s total composition, together with its water, fats, protein, sugars, fiber and antioxidant content material, fluctuate extensively, specialists haven’t outlined a single consumption lower level that predicts hurt for everybody.”

In observe, deal with AGEs like sodium or added sugar: It’s the general sample that issues. “Shifting extra meals towards strategies that cut back AGE formation has been related to enhancements in inflammatory and endothelial stress markers, even with out straight measuring AGEs,” Louati stated.
Your Meals Decisions Nonetheless Matter
Except for cooking strategies, your meals selections play an enormous function in what number of AGEs find yourself in your physique. “The best AGE masses come from animal-based meals which might be wealthy in protein and fats and cooked at excessive warmth — issues like grilled steak, fried rooster, bacon or processed cheese,” Richter stated. “Pastries and baked items that mix sugar, fats and protein are one other main supply, since sugar fuels glycation each throughout cooking and contained in the physique as soon as eaten.”
Then again, crops are typically a lot decrease in AGEs. “Crops typically produce fewer AGEs as a result of they’re naturally decrease in fats and protein, the primary constructing blocks for glycation, and richer in water, fiber and antioxidants,” Richter stated. “However what’s equally vital is nutrient synergy: Crops ship polyphenols, nutritional vitamins and minerals that don’t simply work in isolation, they work collectively.” Vitamin C regenerates vitamin E, serving to stabilize cell membranes. Polyphenols from berries or inexperienced tea scavenge free radicals that will in any other case pace up glycation, whereas herbs like rosemary and turmeric can really block AGE formation on the chemical degree.
Cut back AGEs By way of Easy Prep
Whereas it’s unrealistic to chop out dry-heat cooking strategies fully, you’ll be able to assist decrease the manufacturing of AGEs by being conscious of the way you prep your meals. Louati suggests selecting leaner cuts of meat and limiting added sugars, like in glazes, since sugars and fat on a sizzling, dry floor pace up Maillard reactions. “If you happen to nonetheless need a glaze or shiny end, brush on a really skinny layer within the final minute or two of cooking or toss the meals with a small quantity off the warmth,” she stated. “Construct meals from complete meals and pile on rosemary, thyme, oregano, turmeric, ginger, garlic, onion and black pepper; their vitamins, antioxidants and polyphenols assist neutralize reactive intermediates, and their pure moisture retains browning in test.”
You can even cut back AGEs throughout prep by including acidity, moisture and shorter cooking instances. Marinate meals 30 to 60 minutes in lemon or lime juice, vinegar, yogurt, wine, or tomato to decrease floor pH and gradual the Maillard response. “Use average warmth and briefer cook dinner instances; for instance, cook dinner moist first and end with a fast sear, and reheat with a splash of water slightly than re-browning leftovers,” Louati stated.
The way you cook dinner may be simply as vital as what you cook dinner relating to diet. Small tweaks in cooking strategies can considerably cut back AGE formation, and pairing the appropriate meals with the appropriate methods offers your physique the perfect protection in opposition to ageing components like AGEs.
