I'm not a dietary expert but have you not gone on a Atkins / South Beach / keto / whatever we're calling it this year diet? It's pretty telling. I shed excess weight, I feel amazing and most allergy / autoimmune stuff disappears from my life. The hard part is eating like that the rest of your life.

Even if it did increase risk of heart disease, which I think it most likely does not, I'd rather live a life feeling amazing and die at 75 than feeling subpar all the time living until 95.
