By 2050, global life expectancy, which was 72.6 years in 2019, is expected to increase by approximately five years. [166] Maintaining good nutritional status and adequate nutrient intake is essential for health, quality of life, and overall well-being in older age, and it plays a crucial role in healthy aging as defined by the WHO. [168]
The hand of an older adult Life expectancy in various countries of the world in 2019. Biogerontology is the sub-field of gerontology concerned with the biological aging process, its evolutionary origins, and potential means to intervene in the process. [1]
Calorie restriction (also known as caloric restriction or energy restriction) is a dietary regimen that reduces the energy intake from foods and beverages without incurring malnutrition. [1] [2] The possible effect of calorie restriction on body weight management, longevity, and aging-associated diseases has been an active area of research. [1]
The study, published in the European Journal of Nutrition, utilized data from the UK Biobank and analyzed more than 6,000 cognitively healthy participants in the United Kingdom aged 40 to 73 ...
Free radical damage within cells has been linked to a range of disorders including cancer, arthritis, atherosclerosis, Alzheimer's disease, and diabetes. [13] There has been some evidence to suggest that free radicals and some reactive nitrogen species trigger and increase cell death mechanisms within the body such as apoptosis and in extreme ...
It is predicted that the knowledge of methods to increase the length of cell telomeres (Stem cell and quasi-stem cells, control the regeneration and rebuilding of different tissues of the body) will pave the way for increasing human lifespan. [10] [11] Examining telomeres is one of the most important fields of research related to aging.
