All grains, even whole meal (wheat, rye, oats, corn, barley, millet, bulgur, sorghum, rice, amaranth, buckwheat, sprouted grains), quinoa and white potatoes. this includes all products made from grains (pasta, bread, pizza, cookies, crackers, etc.) sugar and sweets (table sugar, HFCS, agave syrup, ice creams, cakes, sweet puddings and sugary soft-drinks).
Typically you want to stay away from any brands that use filler ingredients like maltodextrin and dextrose, or high glycemic sweeteners like maltitol. Many low-carb products that claim low net carbs usually use these sugar alcohols. Many candies that are “sugar-free” also use these sweeteners. Avoid them where possible. These specific sweeteners respond in our body in a similar way sugar does.
