Nutrition, exercise, and stress management influence our health at the molecular level. Epigenetics demonstrates that we are not only the result of our genetic inheritance but also of our daily choices. Epigenetics studies how environment and lifestyle influence our gene expression, without altering the DNA sequence.
It is the branch of biology that explains how we adapt to the external environment, and why individuals with the same genetic makeup, like identical twins, can exhibit different characteristics and develop different diseases over time.
Our genes contain the instructions for producing proteins, the macromolecules essential for the functioning of cells and organs. Epigenetics acts as a switch or dimmer to regulate the activation of a gene and modulate the amount of proteins produced.
The variable is represented by environmental and behavioral factors:
1. Nutrition: vitamins and antioxidants influence gene activation;
2. Exercise: regular exercise stimulates genes related to metabolism, muscle, and
inflammation;
3. Sleep: sleep deprivation can alter gene expression;
4. Stress management: elevated levels of cortisol negatively affect epigenetics;
5. Exposure to toxins and chemicals can have epigenetic effects.
Movement types and gene activation
a. Moderate cardio training improves cardiovascular function, insulin sensitivity, and brain health: walking, jogging, cycling;
b. Strength training promotes muscle mass, bone density, and basal metabolism by activating genes linked to muscle growth: Pilates with equipment, weights, and resistance training;
c. Low-intensity but consistent activity reduces stress, improves flexibility, and positively influences genes linked to mood and hormone balance: yoga, stretching, walking.
The good news is that we are not powerless over our genes; through daily choices, we can actually program them for the benefit of our health and well-being.
