Genetics and lifestyle: Health is 50% dependent on you
I. Genetics: the foundation of health and predisposition
IA What is genetics?
Genetics is a science that studies the heredity and variability of organisms. She explores how signs and characteristics are transmitted from parents to descendants, as well as mechanisms that lead to changes in these signs. Genetics is based on the concept of a gene – a DNA section containing information for the synthesis of a certain protein or regulatory RNA. These proteins and RNA, in turn, determine the structure and functioning of cells, tissues and organs, forming a phenotype – a set of all observed signs of the body.
IB human genome: Health and Disease Map
The human genome is a complete set of genetic information contained in the cells of the body. It consists of approximately 3 billion pairs of DNA bases packed in 23 pairs of chromosomes. The decoding of the human genome at the beginning of the 21st century became a revolutionary event that discovered new opportunities for understanding the nature of many diseases and developing new methods of diagnosis and treatment. However, it is important to understand that the genome is not a static “book of fate”, but rather a dynamic instruction that interacts with the environment and determines the individual characteristics of a person.
IC genetic predisposition: risks and opportunities
The presence of certain genetic options can increase or reduce the risk of developing certain diseases. This is called a genetic predisposition. It is important to understand that a genetic predisposition is not a sentence. It only indicates an increased probability of developing the disease, but does not guarantee its occurrence. For example, the presence of genes associated with an increased risk of type 2 diabetes does not mean that a person will necessarily get diabetes. A healthy lifestyle, including proper nutrition and regular physical exercises, can significantly reduce this risk.
A genetic predisposition can affect a wide range of diseases, including:
- Cardiovascular diseases: Ichemic heart disease, stroke, hypertension.
- Oncological diseases: breast cancer, lung cancer, colon cancer.
- Metabolic diseases: Type 2 diabetes, obesity.
- Neurodegenerative diseases: Alzheimer’s disease, Parkinson’s disease.
- Mental disorders: Depression, schizophrenia.
- Autoimmune diseases: Rheumatoid arthritis, multiple sclerosis.
ID Genetic Testing: Find out your risks
Genetic testing allows you to identify certain genetic options associated with an increased risk of developing various diseases. There are several types of genetic tests:
- Diagnostic testing: It is carried out to confirm the diagnosis in people with suspected genetic disease.
- Predictive testing: It is carried out to assess the risk of developing diseases in the future.
- Pharmacogenetic testing: It is carried out to determine the human reaction to certain drugs.
- Prenatal testing: It is carried out during pregnancy to detect genetic abnormalities in the fetus.
- Familiar testing of newborns: It is carried out to identify genetic diseases that can be successfully treated at an early age.
Genetic testing can be useful for people who have a family history of diseases, want to evaluate their risks for the development of diseases or plan pregnancy. However, it is important to understand that the results of genetic testing can be difficult to interpret, and it is necessary to contact a qualified geneticist to obtain a consultation.
IE Epigenetics: environmental effects on genes
Epigenetics is a study of changes in genes expression that are not associated with changes in the DNA sequence. Epigenetic changes can be caused by environmental factors, such as diet, physical activity, stress and the effects of toxins. These changes can affect which genes are active or inactive, and, therefore, to the health and development of the body.
Epigenetic changes can be inherited, which means that the lifestyle of parents can affect the health of their children and grandchildren. This opens up new prospects for the prevention of diseases and improve the health of future generations.
II. Lifestyle: the key to the management of a genetic predisposition
II.A. Nutrition: Health and longevity
Nutrition plays a key role in maintaining health and preventing diseases. A balanced diet, rich in fruits, vegetables, whole cereals, low -fat protein sources and healthy fats, provides the body with the necessary nutrients and antioxidants that protect the cells from damage.
- Fruits and vegetables: We are rich in vitamins, minerals, fiber and antioxidants. It is recommended to use at least 5 portions of fruits and vegetables per day.
- Whole cereals: We are rich in fiber, group B vitamins and minerals. Include whole grain bread, brown rice, oatmeal and other whole cereals in your diet.
- Low -fat sources of protein: It is necessary for the construction and restoration of fabrics. Choose low -fat meat, poultry, fish, legumes and tofu.
- Useful fats: It is necessary for the health of the brain and cardiovascular system. Use olive oil, avocados, nuts and seeds.
- Limit consumption: sugar, treated foods, red meat and saturated fats.
Food can affect the expression of genes and epigenetic changes. For example, the use of a large amount of folic acid can affect DNA methylation, which can reduce the risk of cancer.
II.B. Physical activity: move to health
Regular physical activity is one of the most important factors affecting health. It helps to control weight, strengthen the bones and muscles, reduce the risk of developing cardiovascular diseases, type 2 diabetes, some types of cancer and depression.
It is recommended to engage in physical activity of moderate intensity of at least 150 minutes per week or intensively intensity of at least 75 minutes a week. It can be walking, running, swimming, cycling, dancing or other activities that you like.
Physical activity can also affect the expression of genes and epigenetic changes. For example, physical exercises can increase the expression of genes involved in antioxidant protection and reduce the expression of genes associated with inflammation.
II.C. Sleep: time for restoration and regeneration
A sufficient sleep is necessary for health and well -being. During sleep, the body is restored and regenerated, and the memory consolidation occurs. The lack of sleep can lead to a decrease in immunity, an increase in the risk of developing cardiovascular diseases, type 2 diabetes, depression and other diseases.
It is recommended to sleep at least 7-8 hours a day. Create a regular sleep mode and wake up at the same time every day, even on weekends. Avoid the use of caffeine and alcohol before bedtime, and create a calm and relaxing atmosphere in the bedroom.
Dream can also affect the expression of genes. For example, lack of sleep can increase the expression of genes associated with inflammation and stress.
II.D. Stress management: balance and harmony
Chronic stress can negatively affect health, increasing the risk of developing cardiovascular diseases, depression, anxiety disorders and other diseases.
Find healthy ways to manage stress, such as meditation, yoga, walking in nature, communication with friends and family or a hobby. Learn relaxation techniques such as deep breathing and progressive muscle relaxation.
Stress can affect the expression of genes and epigenetic changes. For example, chronic stress can increase the expression of genes associated with inflammation and reduce the expression of genes associated with immunity.
II.E. Refusal of bad habits: health is priority
Smoking and abuse of alcohol are the main risk factors for the development of many diseases, including cancer, cardiovascular diseases and lung diseases.
Refuse smoking and limit alcohol consumption. If you need help, consult a doctor or a specialized center.
Smoking and alcohol can affect the expression of genes and epigenetic changes. For example, smoking can lead to DNA methylation, which can increase the risk of cancer.
III. Interaction of genes and lifestyle: a personalized approach to health
III.A. Personalized medicine: taking into account genetic characteristics
Personalized medicine is an approach to the treatment and prevention of diseases, which takes into account the individual genetic characteristics of a person. This approach allows you to develop more effective and safe treatment methods, as well as give individual recommendations on the lifestyle.
For example, pharmacogenetic testing can help determine which drug and at what dose will be the most effective and safe for a particular person. Genetic testing can also help identify people with an increased risk of developing certain diseases so that they can take preventive measures.
III.B. Nutrigenomy: food adapted to genes
Nrigenomy is a science that studies the interaction between genes and nutrition. She explores how various food products affect genes and how genetic characteristics of a person affect his need for nutrients.
Nutrigenomy can help develop individual diets that will be optimal for the health of a particular person. For example, people with certain genetic options may need more certain vitamins or minerals.
III.C. Individual health plan: a combination of genetics and lifestyle
The best way to manage a genetic predisposition is to develop an individual health plan that takes into account the genetic characteristics of a person and his lifestyle. This plan should include recommendations for nutrition, physical activity, sleep, stress management and rejection of bad habits.
Contact the geneticist or another qualified specialist to obtain consultation and develop an individual health plan.
