Some of the most unhealthy looking people can be found in health food type markets.
not the one i frequent... i have noticed that the people who shop there look to be in good health, good shape... even the older women with gray hair have trim bodies and beautiful skin...
once a year our family goes to Reno, NV to celebrate my daddy's birthday... we hit up a buffet once each trip... i notice that the people who go for the pastries, donuts, coffee cakes along with their breakfast tend to be overweight, bloated with red blotchy skin... the people who go for the fruit with their eggs and bacon and sausage tend to look healthier... that has been my observation...
now i used to work for a guy who was vegan, and he did look sickly... and he was quite often sick with a cold...
I noticed the same thing when I have gone to Whole Foods. I am not sure if it is cause or effect.
