Dietary patterns linked to slower biological aging in new study

A study published in Nature Communications suggests that adhering to healthy dietary patterns is associated with a slower rate of biological aging. Research coordinated by Juliana F. Tavares, involving specialists from German institutions including the University of Bonn, analyzed data from approximately 7,500 adults.

Unlike chronological age, biological age reflects molecular changes associated with the aging of the organism. Researchers utilized three types of epigenetic clocks based on DNA methylation, analyzing roughly 850,000 genetic regions. The study evaluated ten dietary patterns, including the Mediterranean, Nordic, DASH, MIND, and plant-predominant diets.

While these diets differ in specific food recommendations, they share common characteristics: high consumption of vegetables, fruits, whole grains, legumes, and nuts, alongside the limitation of highly processed foods. Molecular analysis indicated that over 70% of the biological pathways associated with the studied dietary patterns overlapped.
