So what if

[7babies]

I did my whole 30.  I reintroduced stuff.  No changes.  Nothing.  I felt fine during the whole 30 and I feel fine now.  Am I just not sensitive?  Did I win a genetic lottery?  Does it benefit me to continue to avoid dairy and grains if they don't seem to make me feel bad?  I'm not a huge eater of these things but I do like some homemade granola and yogurt on a baked potato now and then.  Thoughts?  For the record I run about 30 miles/week am 50 yo, 5'6" 130 ib.  if any of that matters.  Old age maybe might matter.

I'm guessing you weren't eating a lot of the questionable things beforehand (e.g., soda, sugar, and you mentioned you weren't a huge dairy or grain eater).  So, perhaps that's why (and maybe there's some genetic lottery in there) you didn't see much of a difference?

FWIW, I don't consider 50 to be "old," and I don't see what age would have to do with it. If anything, you're running routine is likely more of a factor.

Whether you experience problematic symptoms or not, dairy, grains, etc. make you less healthy. You just have more freedom of choice than some people. Like you, I don't notice symptoms when I eat off plan foods. However, some symptoms are too subtle to notice. For example, about two weeks into my first Whole30, I was sleeping better than I had in 5 years. I have no idea what change in my diet made that difference and I'm not really interested in testing enough to figure out whether it was bagels, yogurt, etc. I just mostly eat meat and veggies and enjoy how well I sleep nowadays.
