According to a study involving over a million people, genetically determined higher iron levels in the blood are associated with a reduced lifespan. This emerging research highlights that while iron is essential for health, excess iron can accelerate cellular aging and promote age-related diseases.

Scientific evidence regarding the keto diet's effect on longevity is contradictory, with some animal studies suggesting lifespan extension and others indicating risks like accelerated organ aging, making the long-term verdict far from settled.

A 2024 study published in *Science Advances* on mice found that a long-term ketogenic diet can induce cellular senescence, or premature aging, in vital organs like the heart and kidneys. This finding challenges the common perception of keto as an anti-aging solution and highlights the need for a deeper look into its long-term effects.

According to a landmark 2018 study, the flavonoid fisetin was identified as the most potent senolytic among a panel of natural compounds. This exciting discovery revealed fisetin as the specific chemical in strawberries that kills zombie cells, offering a promising avenue for healthy aging.

Scientific research has demonstrated that senescent cells, often called 'zombie cells,' play a significant role in the aging process and age-related diseases. A balanced diet rich in specific plant-based compounds can help manage these dysfunctional cells, improving cellular health and slowing the negative effects of aging. This article explores what foods prevent senescent cells by targeting the pathways that contribute to their accumulation.

Research shows that diets high in ultra-processed foods can significantly accelerate cellular aging due to chronic inflammation and oxidative stress. This raises a crucial question: does diet influence cellular senescence, and what role do our eating habits play in the biological aging process?

According to research in animal models, fasting for 24 to 48 hours can promote autophagy, a crucial cellular recycling process that helps eliminate damaged components. This mechanism is central to understanding how long to fast to get rid of senescent cells, although human evidence is still developing.

Research in animal models suggests that fasting can decrease the burden of senescent cells, also known as "zombie cells," which accumulate with age and contribute to various age-related diseases. This exciting area of longevity science is uncovering how dietary patterns might influence cellular aging and regeneration.

According to the World Health Organization, the global population of people aged 60 and over is projected to double by 2050, increasing the focus on healthy aging. A growing body of research now shows that diet can affect senescent cells, the 'zombie' cells that accumulate with age and contribute to chronic disease. By understanding the link between nutrition and cellular health, you can make informed choices to promote longevity.

Research in rodents shows that fisetin can significantly extend lifespan by activating similar cellular pathways to caloric restriction. But does fisetin mimic fasting closely enough to replicate its wide-ranging health effects, and how do these two strategies compare for boosting longevity?
