All about fruitarianism with a long-term fruitarian, Lena

The most frequently occurring clinical indicator of vitamin A deficiency is night-blindness, which is the earliest manifestation of xerophthalmia. 

In its mild form it is generally noticeable after stress from a bright light that bleaches the rhodopsin (visual purple) found in the retina. Vitamin A deficiency prolongs the time to regenerate rhodopsin, and thus delays adaptation time in dark environments.

Night-blind young children tend to stumble when going from bright to dimly-lit areas and they, as well as night-blind mothers, tend to remain inactive at dusk and at night.

The disappearance of a sense of responsibility is the most far-reaching consequence of submission to authority.

Water-soluble vitamins - the body must use almost all water-soluble vitamins right away - vitamins B1, B2, B3, B5, B6, B7, B9 and C.
Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years.
