What percentage of our life span is attributed to genetics?

The assertion that genetics contributes 20-30% to our lifespan aligns with current scientific understanding of the complex interplay between genetic factors and environmental influences on health and longevity. Research indicates that while genetics play a significant role in determining various health outcomes, they do not solely dictate one's life span.

Genetic predispositions can influence susceptibility to certain diseases and conditions, but lifestyle factors such as diet, physical activity, stress management, and exposure to environmental toxins significantly modify these genetic risks. This interaction suggests that genetics provide a baseline or potential for lifespan, but it is the lifestyle choices and environmental factors that often have a more profound impact.

Understanding this balance between genetics and lifestyle is crucial in holistic nutrition, as it underscores the importance of not only knowing one’s genetic background but also actively making health-promoting choices to enhance quality of life and longevity.
