Yes, food is important. Exercise is important. Stress is important. Stimulating with exposure is important. But disease includes inherited susceptibility and issues. Most domesticated sheep for example have lost their resilience to internal parasites and the parasites have developed resilience to dewormers used by farmers. The sheep breeds that still have resilience to parasites are those breeds that have historically been in areas with high disease pressure (typically islands) and better if they are humid where parasites can thrive, without the use of dewormer, where their humans were too poor to afford or didn’t have access or were otherwise left to fend for themselves. Genetics and selective pressures will eventually play a role.
