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.
Glycemic Index. The glycemic index measures how quickly a food causes your blood sugar to rise after you eat it. Foods with a GI score of 55 and under are considered low on the glycemic index, and unlikely to cause blood sugar spikes when consumed in moderation. Foods with a GI score of 70 or over are considered high on the glycemic index and are more likely to cause blood sugar spikes.
