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.
A new pathway comes along
There are plenty of other foods high in dietary nitrates that will boost NO levels and your performance: red or green spinach, arugula, rhubarb, kale, Swiss chard, bok choy, and beets. If you prefer something sweeter, whip up a smoothie of grapes, pomegranate, and apples. The dietary nitrates circulate back into your mouth through your saliva and will boost NO on this second pass.
Persistence in sex and NO production pays off.
