Why Modesto Residents Are Upgrading Their Labs
Many individuals in California are turning to preventative testing for three main reasons:
- Find Answers Standard bloodwork can miss issues like thyroid, hormone, or autoimmune problems.
- Longevity Optimization: You cannot optimize what you do not measure. Function tracks APOB, Insulin, and Cortisol to measure aging.
- Family History: Early detection of cancer signals or heart disease risk factors is possible.
Modesto residents have a remarkable advantage for longevity through their direct access to an abundance of fresh, locally grown produce from the surrounding agricultural heartland. This enables a ‘Plant Slant’ diet, a cornerstone of Blue Zones, promoting nutrient-rich eating and supporting overall health.
However, the car-centric urban design can pose a challenge to integrating consistent ‘Move Naturally’ principles into daily life. Over-reliance on vehicles can limit incidental physical activity, making conscious efforts to walk, bike, or engage in active living crucial for well-being.
By leveraging their agricultural bounty and actively seeking opportunities for movement within their community, Modesto can consciously foster a lifestyle that aligns even more closely with the principles of the world’s longest-lived populations.
