Following research identifying significant scientific misinformation on social media platforms, the Spanish Society of Anti-Aging and Longevity Medicine (SEMAL) and the Salud sin Bulos Institute have released a guide to debunk common longevity myths.

The guide addresses several key areas where social media content often exaggerates or oversimplifies biological processes. Regarding genetics, the initiative clarifies that while genetic heritage contributes between 50% and 60% to longevity, a standard genetic profile accounts for only about 20%, with the remainder determined by lifestyle and environment. 

Addressing dietary trends, the guide notes that while caloric restriction has shown benefits in animal models, there is currently no proven evidence that intermittent fasting or specific diets extend human life. It also refutes claims made by some aesthetic clinics regarding biological age, stating there is no single ‘biological ID’ or test capable of determining an exact biological age.

Finally, the guide emphasizes that while aging increases certain risks, physical and cognitive deterioration is not inevitable. Experts recommend regular physical exercise and adequate nutrient intake to mitigate the loss of muscle and bone density.
