You’re already aware that certain foods — while delicious — can have unsavory effects on your health. But did you know they may also make you age faster? “The foods we choose to eat every day are either adding healthy years to our life or slowly stealing them,” says Dr. Simran Malhotra, founder of Wellness By LifestyleMD in Bethesda, Md.
Just as no single food or supplement can eradicate white hairs or wrinkles, enjoying the occasional burger and fries won’t kill you. However, research suggests that routinely consuming certain foods, including fried foods, sugary drinks and processed meats, could accelerate biological aging. “Chronological age is the number of years someone has been alive, whereas biological age reflects how well someone’s body is aging based on cellular health and organ function," Malhotra explains. “Biologic age is thought to be a better predictor of disease risk and longevity compared to chronological age.”
Several factors contribute to biological aging, some of which (like genetics and environment) are out of your hands. However, others, including diet, are modifiable. Here’s a look at seven foods that may speed up your biological clock, along with some healthier alternatives.
Grilled meat
Cooking meat at high, dry temperatures creates advanced glycation end products (AGEs), harmful compounds that form when proteins or fats react with sugars (a process known as glycation). The body produces some AGEs naturally, but they also occur through cooking. “(AGEs) lead to an accumulation of sugar-coated proteins that cause inflammation, oxidative stress and damage to our vascular health, which can lead to chronic diseases like diabetes and heart disease," Malhotra says. “AGEs can also reduce skin elasticity, destroy the skin barrier, and damage collagen and elastin, leading to more wrinkle-prone skin."
Animal-based foods, including grilled and fried meats and baked goods, tend to have the most AGEs, Malhotra says. Processed meats like bacon and sausage, high-fat cheeses, butter and margarine are also high in AGEs, says Angel Planells, a Seattle-based spokesperson for the Academy of Nutrition and Dietetics.
Tip: Because higher-fat meats are more prone to AGEs, using leaner cuts of meat and cooking at lower temperatures can help reduce AGE formation, says Alyssa Pacheco, owner of the PCOS Nutritionist Alyssa in the Boston area. “Additionally, using a meat marinade that contains an acid, such as vinegar or citrus juice, can reduce the formation of AGEs significantly," she says.
Planells also suggests incorporating more plant-based foods, including legumes, beans, nuts, seeds, fruits and vegetables, into your diet. Many of these are rich in compounds, such as antioxidants, that help combat AGEs and their effects. In fact, one 16-week randomized control trial found a plant-based vegan diet reduced AGEs by 79%, among other health benefits.
Fried foods
Fried foods — including French fries, doughnuts and fried chicken — also tend to be high in AGEs. Plus, they’re often high in trans fats. Whereas some fats (such as omega-3 fatty acids) may help improve your health and lifespan, trans fats could have the opposite effect. Examples of trans fats include partially hydrogenated vegetable oils, stick margarine and shortening, according to the Mayo Clinic.
