Id beleve it.
I have a disease like MS and foods among other things effect it seriously. I went to grill some turkey burgers a few weeks ago on a new grill I purchased little more than a year ago. Just been too busy and this summer was too hot for a cook out.
Anyway, it brought back memories. I loved the smell. I cooked a whole box of 12 burgers. I went to dig in and about the 4th burger I lost my steam. Yeah, I am a big eater, I usually eat a lb of ground chicken or turkey a day or at a sitting if I have been busy.
Anyway, I was sick feeling, head ache, etc for the next 8 hours. I gave away the grill and rest of the coals to a neighbor.
I follow a lot of food rules that cancer people do. I find food thats been sitting or old can cause me to feel run down as well as the benefits of organic vs regular food.
