OP: Sorry about the suspicions that you were just spamming.
I've read that the introduction of wheat into the diet of a developing nation is associated with short sightedness. Do you believe it's wheat specifically or just any insulin spikes associated with higher carb consumption that cause myopia? Of course as wheat is addictive for many it will lead to more insulin spikes daily. If its insulin spikes alone that are to blame, then snacking and eating chronic low fat would be major contributing factors wouldn't they?
