A recent study published in the journal Cell has provided new insights into the aging process, revealing that it may start to accelerate as early as 45 years old. Researchers analyzed proteins in tissue samples from over 70 people aged 14 to 68 and found that aging begins to take hold when cells’ ability to produce proteins correctly starts to break down.
The study’s findings suggest that organs such as the heart, liver, pancreas, and skin begin to show signs of aging around age 30, while others like the spleen, aorta, and adrenal gland start to age at around 45. The aorta, which carries blood throughout the body, showed significant changes in protein levels between ages 45 and 55.
The research’s implications are significant, as it could lead to new treatments for chronic conditions related to aging that not only increase lifespan but also improve healthspan – the period of life spent in good health. While diet, exercise, genetics, and luck have been shown to impact longevity, this study suggests that people may still see benefits from making changes later in life.
According to Dr. Thomas Blackwell, “Starting at 45 or 50, you could gain as much as 10 years of healthy life.” The study’s findings are a valuable resource for researchers and healthcare professionals looking to develop new therapies to restore healthy aging.
