To prevent hypoglycemia, you should have a snack containing 15 g of carbohydrates.
Snacks are a way of dealing with hunger between meals. Snacks can help you maintain concentration at work and eat reasonably at your next meal.
A snack is indicated in certain circumstances, to:
- Prevent hypoglycemia (blood glucose < 4 mmol/L)
- Meet your nutritional needs
- Help you avoid overeating
1. Prevent hypoglycemia
You are at risk of hypoglycemia if you take insulin or an insulin secretagogue: glyburide (Diaßeta®, Euglucon®), glimepiride (Amaryl®), gliclazide (Diamicron®), repaglinide (GlucoNorm®).
A snack can help prevent hypoglycemia if you find yourself in any of the following situations:
- your meal is delayed;
- you have not been rigorously following your meal plan;
- you are drinking alcohol on any empty stomach or in the evening;
- you are unexpectedly exercising or doing some physical activity at a higher-than-normal intensity or duration;
- your medication’s peak action occurs while you are sleeping.
To prevent hypoglycemia over a longer period of time, add some protein to your snack. Protein is found in the Milk and Alternatives and Meat and Alternatives food groups.
2. Meet your nutritional needs
If you have a small appetite, snacks are an important way to meet your nutritional needs. Snacks do the job of providing the calories and nutrients necessary to maintain your health.
3. Help you avoid overeating
Snacks can help moderate your appetite and lower the risk of overeating. To stave off hunger pangs until the next meal, snacks should contain:
- Fibre: Fibre doesn’t increase blood glucose levels. Fibre swells in the liquid in the stomach and makes you feel full faster.
- Protein: The satiating effect from protein persists, which helps you wait until the next meal.
- Carbohydrates: They increase blood glucose levels and counter the lack of energy resulting from hunger.
Real or False Hunger?
Glucerna® and Boost® Diabetic, which promote themselves as “meal substitutes,” are not recommended as snacks for most people with diabetes, since these drinks contain too many calories.
Learn to distinguish between real and false hunger by being aware of the triggers that prompt you to eat.
To help you decide, here are a few questions to ask yourself:
- Am I eating because I feel stressed or emotionally upset?
- Am I reacting to an external stimulus (for example: the sight or smell of food, colleagues offering me food, etc.)?
- Am I eating because my meals aren’t sufficiently balanced or filling?
To find the answer to your question, keep a food diary that notes not only what you’ve eaten but also your emotions and the context at the time (environment, particular event).
After you become aware of your pattern, don’t hesitate to discuss possible strategies with a dietitian or another member of your diabetes health care team.
