Does pizza send your blood sugar all over the place? Does your favorite smoothie send it soaring? If you\u2019re living with type 1 diabetes (T1D), managing blood sugar levels at mealtime can be complicated and daunting.<\/p>\n

Fortunately, there are ways to minimize blood sugar variations after meals; here are a few strategies that may help.<\/p>\n

Calculate carbohydrates as accurately as possible\u00a0<\/b><\/h2>\n

The amount of carbohydrates you consume<\/b> is the most impactful<\/b> on your blood sugar levels following a meal. Still, there are a multitude of other factors that can cause hypoglycemia or hyperglycemia<\/a>. That\u2019s why you determine your rapid-acting insulin dose (or bolus) before<\/b> each meal and snack based on the number of carbs on your plate. Studies show that accurate carb counting reduces blood sugar fluctuations following a meal.<\/p>\n

Consider the impact of protein and fats<\/b><\/h2>\n

Your meals usually won\u2019t be made up of carbohydrates only. Meals also include two nutrients that affect blood sugar levels: protein<\/b> and fat.<\/b> Indeed, protein<\/b> (e.g., in meat, fish, eggs, dairy products, tofu, legumes) will have small but direct impact<\/b> on blood sugar, raising it very slowly up to 4 to 12 hours after the meal. Fats<\/b> (e.g. in meat, deli meats, fried foods, butter, oil and avocado) delay the absorption of carbohydrates<\/b> and, consequently, raise blood sugar levels several hours after the meal<\/b>. Consuming a large amount of fat during a meal will also impact the body\u2019s ability to use insulin (insulin resistance).<\/p>\n

So, when your meal is high in fat and\/or protein<\/b> (e.g., pepperoni and cheese pizza or steak and fries), it\u2019s best to take this into account when calculating your insulin dose. Some studies suggest adding 25% of your calculated dose to your bolus to mitigate the impact of protein and fat. For instance, if your calculated dose is 10 units, you\u2019d to add 25% of 10 units (2.5 units), for a total of 12.5 units.<\/p>\n

Inject insulin at the right time<\/b><\/h2>\n

It is usually recommended to administer your insulin bolus before eating<\/b> so that the insulin action better matches the rise in blood sugar. Bolusing\u00a05 to 15 minutes (depending on your type of rapid insulin) before eating a balanced meal leads to a lower rise in blood sugar levels.<\/p>\n

If you eat foods that are low in fibre and fat, but high in simple sugars<\/b> (e.g., white bread toast with jam or a smoothie), you may want to bolus up to 45\u00a0minutes before your meal<\/b>. This should ensure that insulin is already acting<\/a> by the time you start eating, curbing the quick rise in blood sugar associated with simple sugars (CAUTION: don\u2019t use this strategy if your blood sugar is low before the meal!).<\/p>\n

Conversely, if you eat a meal high in fat and\/or protein<\/b> (e.g. pepperoni and cheese pizza), you may want to consider splitting<\/b> your insulin dose in two: one to be given when you start eating, and the other when you\u2019re finished eating.<\/p>\n

Aim for a balanced diet<\/b><\/h2>\n

A balanced meal (as recommended by Canada\u2019s Food Guide<\/a>) makes blood sugar management easier, since the impact on practically matches the insulin action curve. As often as possible, you should aim for a well-balanced plate, i. e., with half fruits and vegetables, a quarter whole grains and a quarter protein.<\/p>\n

When you\u2019re dining out or having a special occasion meal, there are still ways to limit variations in blood sugar levels. For example, a slice of pepperoni and cheese pizza with a salad is less likely to send your blood sugar on a roller coaster ride. If you\u2019re craving cookies, cakes, candy or chocolate, eat them as part of a meal rather than on their own. The same goes for alcoholic beverages. Alcohol can lower blood sugar levels some time after consumption, so carbohydrates from a meal or snack can act as a safety cushion.<\/p>\n
