I've noticed that since I've cut out gluten and other grains (on rare occasion I will still eat rice) pre menstrual breast tenderness/pain (ie. swollen lymph nodes on the sides of my breasts) has gone way down. That's very nice because it had reached an almost worrisome level before i kicked the grains.
It seems like your lymphatic system is one of the first lines of defense against naughty stuff that's made its way into your system and a major initiator in it being carried out of your body. How does paleo help out the lymphatic system and have you noticed any changes in yours since going paleo?
