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.
Choose high-fiber carbohydrates that will help keep you feeling full. Carbohydrates raise your glucose levels -- and sugary carbs can quickly spike your blood sugar. These spikes are often followed by dramatic drops, which can cause a craving for more carbs, as hypoglycemia sets in. Fiber slows the conversion of food into glucose and will stop your blood sugar from rising too quickly.
