Longevity: myths and reality about life up to 100 years
Chapter 1: Genetics and longevity: Is the future predetermined?
Longevity, the desire for a long and healthy life, has long been concerned about humanity. One of the key issues in this area concerns the role of genetics: how much is our longevity predetermined by our heredity? The study of longevity genetics is a complex and multifaceted task that requires an integrated approach and analysis of huge amounts of data.
1.1. Longevity genes: the search for the Holy Grail.
Scientists are actively looking for specific “longevity genes” that could explain the phenomenon of the exclusive life expectancy. However, as practice shows, everything is much more complicated. Instead of one or more “champions genes”, we are more about the Complex Intection of Multiple Genes, Each Contributing A Small Effect.
-
Genes participating in DNA reparations: DNA damage accumulates with age, increasing the risk of various diseases. Genes responsible for DNA reparation, such as WRN (Verner syndrome) and BLM (Bloom syndrome), play a critical role in maintaining genomic stability and, as a result, in a slowdown in aging process. Mutations in these genes lead to premature aging and reducing life expectancy. Conversely, the increased effectiveness of DNA reparation can contribute to longevity.
-
Genes associated with the immune system: Effective operation of the immune system is crucial for combating infections and tumors, which become more common with age. Genes that control the functions of immune cells, inflammatory reactions and autoimmune processes play an important role in determining susceptibility to age -related diseases. Polymorphisms in genes HLA, IL-6, TNF-α associated with longevity in some populations.
-
Genes regulating metabolism: Metabolic processes, such as regulation of glucose levels, sensitivity to insulin and lipid metabolism, directly affect health and longevity. Genes encoding the insulin-like growth factor 1 (IGF-1) and sirtuins (SIRT1-7) attract special attention. A decrease in IGF-1 activity and the activation of sirtuins showed a positive impact on life expectancy in various organisms.
-
Genes that control cellular aging (sensocal): Senscent cells are cells that have ceased to be divided, but continue to secrete harmful substances that contribute to inflammation and damage to surrounding tissues. Genes that regulate the processes of sensoryness, such as p16INK4a And p21play an important role in determining the speed of aging and the risk of age -related diseases.
1.2. The role of genetics in the families of centenarians.
The study of families of long -livers is a valuable tool for studying longevity genetics. The study of the genomes of people who have lived for more than 90 or 100 years allows you to identify genetic options that are more often found in these families and can be associated with an increase in life expectancy.
-
Inheritance of longevity: Studies show that longevity tends to be inherited. Children of long -livers have more chances to live a long life than children of people with an average life expectancy. However, the degree of heredity of longevity varies in different studies and depends on various factors, including the genetic background, lifestyle and the environment.
-
Genetic markers of longevity in families of long -livers: In families of centenarians, various genetic markers were identified, which may be associated with an increase in life expectancy. These include variants of genes involved in lipid metabolism (for example, APOE), regulation of inflammation (for example, IL-10) and protection against oxidative stress (for example, Sod2).
-
Epigenetic factors in the inheritance of longevity: Epigenetic factors, such as DNA methylation and histone modification, play an important role in regulating genes expression and can affect the phenotype without changing the DNA sequence. Epigenetic changes can be transmitted from generation to generation and influence the life expectancy of offspring.
1.3. Genetics and environment: interaction of genes and lifestyle.
Despite the important role of genetics, longevity is not determined only by genes. The lifestyle and the environment have a significant impact on life expectancy and can modulate the effect of genetic factors. The interaction of genes and the environment is Complex InterPlay, where a genetic predisposition can be enhanced or weakened by environmental factors.
-
Nutrition and longevity: Crucial Role in Determining Healthspan and Lifespan plays. The limitation of calorie content, interval starvation and the consumption of certain products, such as fruits, vegetables and fish, are associated with increasing life expectancy and reducing the risk of age -related diseases.
-
Physical activity and longevity: Regular physical activity has a positive effect on the cardiovascular system, immune system and metabolism, reducing the risk of developing chronic diseases and increasing life expectancy.
-
Stress and longevity: Chronic stress negatively affects health and can accelerate aging processes. Stress management using various techniques, such as meditation, yoga and social support, can contribute to longevity.
-
Environmental influence (toxins, pollution) on genetic expression: exposure to environmental toxins and pollutants can alter gene expression and increase the risk of age-related diseases, negating the beneficial effects of genetic predisposition to longevity.
Chapter 2: Life and longevity: a choice affecting the years of life.
A genetic predisposition is an important factor, but a lifestyle has a huge impact on the duration and quality of life. Healthy habits can significantly increase the chances of longevity, even in the presence of adverse genetic heredity.
2.1. Food as the basis of a long and healthy life.
Proper nutrition is the cornerstone of longevity. What we eat directly affects our health, energy and resistance to disease.
-
Mediterranean diet: gold of the standard of longevity. This diet, based on the traditions of nutrition of the peoples of the Mediterranean, is rich in fruits, vegetables, whole grains, olive oil, fish and legumes. It is associated with a reduction in the risk of cardiovascular diseases, cancer, diabetes and dementia.
-
Calorie restriction: the key to the slowdown of aging? Animal studies have shown that the restriction of calorie content (reducing calorie consumption by 20-40%) can significantly increase life expectancy. Although the results of studies in public are less unambiguous, the limitation of calorie content is associated with the improvement of metabolic indicators and a decrease in the risk of age -related diseases.
-
Interval fasting: rebooting the body. Interval fasting is a diet in which the periods of food intake alternate with periods of starvation. There are various options for interval starvation, for example, a scheme of 16/8 (16 hours of starvation, 8 hours of food intake) or 5: 2 (5 days of conventional diet, 2 days with a calorie restriction). Interval fasting can improve insulin sensitivity, reduce inflammation and promote autophagy (the process of cell treatment from damaged components).
-
The role of macro- and trace elements in longevity:
- Squirrels: It is necessary for the construction and restoration of fabrics. It is important to consume a sufficient amount of protein, especially with age, to prevent muscle loss (sarcrophy).
- Carbohydrates: The main source of energy. Preference should be given to complex carbohydrates (whole grains, vegetables, fruits) instead of simple (sugar, refined products).
- Fat: It is necessary for the assimilation of vitamins, the production of hormones and maintaining brain health. It is necessary to give preference to unsaturated fats (olive oil, fish, avocado) instead of saturated (fatty meat, dairy products).
