Understand how diet and lifestyle affect biological age
A recent study published in the US Journal of Aging in 2021 added an interesting dimension to the field of health and longevity. The study, led by Dr. Kara Fitzgerald, found that just eight weeks of a nutritious diet and lifestyle reversed biological age by more than three years. The results of this study highlight that diet and nutrients can extend healthspan and longevity.
The power of calorie restriction
One important strategy to promote longevity is calorie restriction. Several studies have confirmed its significant impact on longevity and healthspan. Calorie restriction works by reducing free radical production, protecting the thymus gland, and improving metabolic health. By slowing your metabolic rate and minimizing cell damage caused by free radicals, you extend your lifespan. For example, the CALERIE trial demonstrated the health benefits of calorie restriction in humans, including thymic rejuvenation and reduced expression of PLA2G7, a protein associated with age-related inflammation. Additionally, calorie restriction has been shown to improve metabolic rate and reduce age-related inflammation.
Diet and longevity
A variety of dietary habits are thought to be associated with longevity and longevity. These include eating nutritious foods, plant-based diets, Mediterranean diets, mindful eating, calorie intake, and maintaining a balanced macronutrient diet. Each of these ingredients plays an important role in promoting longevity and overall health.
The role of nutrients in longevity
The role of diet and nutrients in influencing healthspan and longevity cannot be overstated. Dietary interventions such as calorie restriction, intermittent fasting, and polyphenol intake can have a significant impact on aging and disease. Certain nutrients, such as folic acid and B vitamins, are particularly important in this regard and play a key role in one-carbon metabolism. The intestinal flora, which is influenced by our diet, also plays an important role in human health.
Protein – essential for longevity
Protein intake is another important factor determining longevity. Protein supports muscle maintenance, immune function, and various metabolic processes. Research highlights that adequate protein intake is an important determinant of longevity. A 2014 study found that a high-protein diet was associated with reduced cancer and overall mortality rates in people over the age of 65. For people under 65 years of age, lower protein intake was associated with beneficial health effects. Remarkably, consuming plant-based protein was found to be more effective at preventing mortality than protein from animal sources. Therefore, incorporating a variety of healthy protein foods, including plant proteins, can support overall health and longevity.
conclusion
In conclusion, diet and lifestyle have a significant impact on biological age, healthspan, and longevity. Calorie restriction, a nutritious and balanced diet, conscious eating, and adequate protein intake are all keys to promoting longevity. Research led by Dr. Kara Fitzgerald highlights the potential to reverse biological age through dietary and lifestyle modifications. These findings serve as an important reminder that it's never too late to make positive changes to your diet and lifestyle for a longer, healthier life.
