A new study reveals that reducing daily added sugar intake by 10 grams could potentially reverse biological age by 2.4 months. This significant finding underscores the impact of diet on biological aging.

The research analyzed food records from 342 Black and White women who participated in the 1987–1997 National Heart, Lung and Blood Institute Growth and Health Study. The study compared these women’s diets to a Mediterranean-style diet, which is known for its anti-inflammatory and antioxidant properties. Researchers also evaluated the diets using an Epigenetic Nutrient Index, which scores nutrients based on their role in antioxidant processes and DNA maintenance. Key nutrients included vitamins A, C, B12, E, folate, selenium, magnesium, dietary fiber, and isoflavones.

Outcomes highlights that adherence to a healthy diet, particularly the Mediterranean diet, was significantly associated with a lower epigenetic age. The study found that the Mediterranean diet, rich in fatty acids, antioxidants, and carotenoids, had the most substantial effect on reducing biological age.

Additionally, the research identified that high consumption of added sugar was linked to accelerated biological aging, even among those following a generally healthy diet. Experts also emphasized that high levels of added sugars are connected to worsened metabolic health and increased risk of early disease. The study highlights that excessive sugar intake may contribute to accelerated epigenetic aging, further impacting longevity.

Participants in the study consumed an average of 61.5 grams of added sugar daily, exceeding the US FDA’s recommended limit of 50 grams. The range of sugar consumption varied widely, from 2.7 to 316 grams per day. Previous research has also linked higher free sugar intake to increased cardiovascular disease risk, reinforcing the health risks associated with excessive sugar consumption.
