Anyone notice that their skin does not burn as much after following a
paleo diet?  I sure have.

I am careful to stay in the shade during
the hottest part of the day, but I don't feel as sensitive to the sun
as I used to.  It reminds me of when I was a kid and I would be out
playing all day and get a really dark tan, but never burn.
I feel very wary of sunscreen manufacturers promoting their products
and the idea of putting such
chemicals on my skin.  I think it is promoted as being "safe" and
"protection", which people eat up (so to speak) and slather it on
their kids...
I have read that sesame oil has a natural SPF though very low, about
5.  I use that on my skin and on my daughter's skin when we are out in
the sun.
