Why Tustin 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.
Tustin residents possess a significant advantage in adopting ‘Blue Zone’ principles, particularly in ‘Move Naturally.’ The city’s numerous parks, pleasant year-round climate, and well-maintained trails encourage daily physical activity, making movement an integral part of life rather than a chore. Furthermore, Tustin’s strong community fabric often supports ‘Loved Ones First’ and ‘Belong’ principles, fostering essential social connections and a sense of purpose through civic engagement.
Conversely, a primary challenge for Tustinites lies in consistently practicing ‘Down Shift’ and the ‘80% Rule’ for eating. The typical fast-paced Southern California lifestyle, coupled with easy access to processed foods and large portion sizes, can make mindful eating and dedicated stress reduction difficult. Residents must consciously carve out time for relaxation and intentionally opt for the fresh, plant-rich foods available to fully embrace these longevity habits amidst modern demands.
