Well, for us, following the recommendations by Dr. Sears, my son was able to function better without his Ritalin and manage to go to the college of his choice which earlier seemed not a viable option.

I reversed my asthma, and long standing GERD (although I still have my GI congential twisted problem and a hiatal hernia), and improved my skin tone considerably by following the Zone diet. I no longer need daily medications for either of these past painful issues.

Removing trans fats, consuming more Omega-3s (which today is easier because of smart foods available) and reducing carbs and sugar, avoiding fried foods-- all were highly successful.

We all still take our fish oil (I've switched myself to Krill oil), consume more flax products (Smart Balance helps with this).
Buy Omega-3 enriched eggs. We use magnesium to support the EFA chemistry. I find today, I am pretty balanced and can take less supplemental fish oil. Hubby won't eat the enriched peanut butter so he still takes fish oil and flax oil. One a day.

We rarely get sick any more. I don't need asthma inhalers anymore but keep one as a rescue. Typically it expires without being used even.

It took a bit of getting used to...but we did it. I find others less enthusiastic about changing diet enough to improve health, so supplements are easier for those types of folks.

Today at my age I am favoring antioxidants more heavily than before.
