Women need 25 grams of fiber per day, and men need 38 grams per day, according to the Institute of Medicine. Eating more plant foods -- vegetables, beans, fruit, whole grains, and nuts -- is the best way and is one of the recommendations from the U.S. government's 2015 Dietary Guidelines.
The epidermis is the outer (epi in Greek meaning over or upon) of the two layers that make up the skin (or cutis), the inner layer being the dermis.
1 Stratum granulosum is made up of keratinocytes that have moved up from the squamous layer. As these cells move closer toward the skin's surface, they begin to flatten and stick together, eventually drying and dying out. 2  Stratum corneum is the outermost layer of the epidermis.
