Black Pepper
If You Read Nothing Else

The heat and most of the effects come from one compound, piperine.
Piperine greatly increases how much curcumin (the yellow compound that gives turmeric its colour) from turmeric reaches the blood.
It gently increases stomach juices, which is why it is used before heavy meals.
Grind it fresh. Ground pepper loses its punch within a few months.
