I love peanuts, cashews, pecans, walnuts, and sunflower seeds. However, walnuts are the one and only out of the group in which I cannot eat as I get terrible back pain after consumption of them.
Aside from walnuts having a great taste that highly appeals to me they are also very nutritious. As a child I was able to eat these type of nuts continuously without a problem. I must had developed an allergenic reaction from walnuts over the following years or they just no longer agreed with my body chemistry. I was about sixteen when I first experienced any unfavorable response.
I tried once again when I reached adulthood to see if my body was able to tolerate the constitutes of walnuts. I was not successful at my attempt and disappointed at how I would never possibly be able to take pleasure indulging in what use to be one of my favorite nuts to crack open and devour.
