The term secondary market is also used to refer to the market for any used goods or assets, or an alternative use for an existing product or asset where the customer base is the second market (for example, corn has been traditionally used primarily for food production and feedstock, but a second or third market has developed for use in ethanol production).
What you eat with your carbohydrates matters, too. Protein and fat slow the absorption of glucose into the bloodstream, which helps prevent [insulin] spikes and drops, says Jamieson-Petonic.
Unfortunately, all grains will raise blood sugar, and really NONE are slow carbs. The only way to make them slow is to add more fiber (I add ground flax seed to my oatmeal) and start your meal with protein. Eggs, ham, leftover chicken, lean steak, you know, even well-cooked bacon works.
