Diet is only one aspect of human health. Clean water, lots of it, for drinking and bathing, is essential. Regular activity and movement, whether exercise or work, is necessary and natural for sustaining health. Humans are social and need interaction with people. Getting enough sleep (and rest), enough light (but not too much), continuing to challenge the mind, overcoming problems from the past, having fun, feeling connected with Nature or God, finding meaning and purpose all contribute to the big picture of human health.
