A recent study has challenged a popular belief that eating carbohydrates speeds up aging. In fact, the research suggests that eating the right kind of high-carb diet might actually help slow down or even reverse the aging process. The findings, published in the journal Aging Cell, indicate that for older adults, a short-term dietary change can make a measurable difference in their body’s biological age.
Your biological age is different from your chronological age, which is simply the number of years you have lived. Biological age reflects how well your body is functioning on the inside. Researchers often use it to predict future health risks more accurately. In this study, scientists from the University of Sydney used a method that analyzes specific health markers in the blood and body, like cholesterol levels and blood pressure, to calculate this biological age.
The experiment involved 104 healthy participants aged 65 to 75, who were randomly divided into four groups for four weeks. One group ate an omnivorous (杂食的), high-fat diet, which closely matched what many people normally eat. The other three groups tried different patterns: one was an omnivorous, high-carbohydrate plan; another was a semi-vegetarian, high-fat plan; and the last was a semi-vegetarian, high-carbohydrate plan. All meals were carefully provided and monitored to ensure they followed the diets exactly.
The results were surprising. Compared with the high-fat diet group, whose biological age remained almost unchanged, the omnivorous high-carbohydrate group showed a remarkable reduction, lowering their biological age by nearly four years on average. The groups on the semi-vegetarian diets also saw a trend toward a younger biological age. Critically, the carbohydrates they consumed were “good” complex carbs from whole, unprocessed foods, not refined sugars or white flour.
The scientists believe several mechanisms may explain these benefits. A diet rich in complex carbohydrates can lower chronic inflammation, a key driver of aging. It also improves metabolic health by stabilizing blood sugar and supports healthy gut bacteria (肠道菌群). This research strongly suggests that for lasting health, the quality of your carbohydrates is more important than simply reducing their quantity.
