Some evidence shows that a wide range of carotenes protect against diabetes. The leading sources of carotenes are the dark green leafy vegetables: kale, collards, and spinach.

Symptoms of zinc deficiency include fatigue, along with increased rate of infections and injuries. Low zinc can cause dwarfism and delayed sexual development. Mothers with a zinc deficiency tend to have smaller babies and babies with smaller-than-normal brains.
