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.
Eating fat and protein can affect how quickly your body turns carbohydrates into sugar. When you know the amount of carbohydrate, protein, and fat you're eating at a meal, you can learn to choose foods that help to keep your blood sugar levels even. The total amount of calories you eat every day is also important.
