Aging & Eating
People can age biologically faster or slower than they age chronologically. Biological aging can be measured using epigenetic clocks, which are computational models that assess health and lifespan, and predict biological age.
Suboptimal eating patterns increase disease and mortality risks. Researchers examined the association between eating patterns and biological aging in young adult twins.
Researchers conducted a study on 363 pairs of twins, ages 20-25, to compare the impact of eating patterns on biological aging. Participants completed a food frequency questionnaire that evaluated their typical consumption of 55 different foods. They discovered that:
Consuming more red and processed meat, fast food, and sugary drinks, along with few fruits and vegetables, was associated with faster biological aging, while
Consuming more fruits and vegetables, along with limited red and processed meat, fast food, and sugary drinks, was associated with slower biological aging.
Researchers conducting the study theorize that polyphenols, which are found mainly in vegetables, fruits, berries, nuts, herbs, soy, tea, coffee, cocoa, and olive oil, may explain the deceleration of biological aging in the twins that ate more fruits and vegetables.
Takeaway: To slow biological aging, consider:
Eating more foods that are rich in polyphenols, such as vegetables, fruits, berries, nuts, herbs, soy, tea, coffee, cocoa, and olive oil, and
Limiting red and processed meat, fast food, and sugary drinks.
Well-being is a journey, not a quick fix.
Important Note: This newsletter has reached a threshold of readers that makes it more expensive for me to send it to you. This week, I will be working to migrate the readers that have subscribed to The Professional Brain to my Substack newsletter, Never Too Late (to improve your brain health or mental strength), where it is free for me to provide to readers, and where it may also reach a new audience. This weekly well-being nudge will always be free to my readers.
My book, The Legal Brain: A Lawyer’s Guide to Well-being and Better Job Performance, is available at Barnes and Noble and Amazon.
