Foods that raise NO: the hard facts
When the Nobel Prize in Medicine was awarded for identifying the role of NO in artery health, the importance of dietary L-arginine was identified. L-arginine is converted by an enzyme called eNOS (rhymes with the male organ) into NO. There are foods that are particularly rich in L-arginine and would be good pre-date snacks. These include whole grains like oats, pine nuts, peanuts, walnuts, almonds, pistachios, and Brazil nuts.
Another path to peak NO production is to eat foods high in L-citrulline. L-citrulline is produced as a byproduct when arginine is converted to NO and can cycle back to make more L-arginine. L-citrulline is most concentrated in watermelon, particularly in the white rind. It is also found in onions and garlic, although they may be a bad idea before a date unless everyone partakes.
