I have mentioned this on this blog before but so many complain of afternoon slumps I thought another post might be in order. Whatever you do when you feel that afternoon slump coming on, don't grab a candy bar or other sweet treat. You need something protein rich to combat the slumps. British researchers suggest a snack that includes hummus or eating a hard boiled egg for a boost in pep. The reason? Amino acids in protein stimulate certain brain cells that make you feel more alert, according to the study's lead author Denis Burdakov, Ph.D. Protein rich foods are also rich in tyrosine, an amino acid needed to help the body produce noradrenaline another brain chemical that perks you up.
