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.
Even though glass noodles are high in carbohydrates, they do not cause a spike in blood sugar. The glycemic index rates carbohydrate-containing foods according to how much they boost blood sugar. Foods are ranked on a scale of zero to 100, where 100 represents glucose, which causes a big surge in blood sugar.
