L-cysteine is also a good idea if we have addictive allergic eating habits. Because of certain neuroendocrine payoffs it's easy for the brain to rewire itself to crave whatever our favorite immune-stimulating allergens happen to be. When we indulge these cravings our bodies produce nitric oxide (NO). NO makes our blood vessel walls more permeable, which is why we swell up and get clogged when we have allergic reaction. NO can become peroxynitrate, a biologically essential oxidant that's also the most dangerous free radical in the body. 80
