The first ingredient to avoid is hydrogenated oil, which often masquerades as partially hydrogenated oil. Dr. Roizen says we should also eliminate sugar and high fructose corn syrup from our foods. "We eat 63 pounds of [high fructose corn syrup] a year, which puts 33 pounds on the typical American," he says.
Enriched flour is the fourth ingredient to avoid. "[Enriched] means they took all the good stuff out and put a little back," Dr. Roizen says. In 1960, Americans didn't use enriched flour, but today we consume 63 pounds a year, he says.
The fifth offenders are white foods—including bleached flour. The only white items you should have in your fridge are egg whites, cauliflower and fish, Dr. Roizen says.
