Yet you must have heard to take almonds, cashews, dates, pistachios and walnuts with caution, else too much of them can result in excessive body heat, giving rise to nasty pimples and rashes. According to a common belief, overeating dry fruits can prove to be a risky affair for those with sensitive skin. It is believed that nuts are highly rich in proteins, which activates the oil glands, especially on the face. More secretion of oil means more clogged pores, hence more pimples. Dates also have the reputation of increasing body heat.
