When we think of blood sugar, diabetes often comes to mind. However, blood sugar regulation is crucial for everyone’s overall health, not just for those with diabetes. Maintaining steady blood sugar levels plays a key role in managing energy, mood, and even long-term health results.
Here, we’ll dive into how blood sugar works, what causes spikes, and some tips to maintain steady levels throughout the day.
What is Blood Sugar?
Blood sugar refers to the amount of glucose in your bloodstream. Glucose is your body’s primary source of energy and it mainly comes from the food you eat—especially carbohydrates like bread, fruit, and vegetables.
How the Body Uses Glucose
After you eat, your body breaks down carbohydrates into glucose, which then enters the bloodstream. From there, glucose is transported to your cells to be used for energy.
To manage this process, your pancreas produces insulin—a hormone that helps glucose enter your cells. Think of insulin as a key that unlocks each cell, allowing the glucose to enter. It also plays a crucial role in maintaining balanced blood sugar levels.
What Are Blood Sugar Spikes?
A blood sugar spike happens when your glucose levels rise too high or too quickly—usually after eating foods high in refined sugars and simple carbohydrates (like sugary desserts, candy, soda, or white bread).
Refined sugars and simple carbs are digested very quickly by the body, which leads to a rapid release of glucose into the bloodstream—faster than the body can efficiently manage, resulting in a spike.
Why Spikes Are Problematic
Frequent spikes can throw your body off balance. You might feel energetic for a moment, but it’s often followed by an energy crash, increased hunger, cravings, and even anxiety.
Over time, repeated spikes can lead to insulin resistance, where your body becomes less effective at using insulin. This can increase the risk of chronic issues like heart disease, kidney problems, nerve damage, and type 2 diabetes.
How to Prevent Blood Sugar Spikes and Maintain Steady Glucose Levels
Blood sugar levels can easily be stabilized with some simple, intentional habits.
Eat Balanced Meals
When you eat, aim to include a mix of fiber, protein, and healthy fats. These slow down the digestion and absorption of sugars, preventing rapid spikes.
Grilled chicken (protein) + brown rice (fiber-rich carb) + avocado and olive oil (healthy fats)
This kind of meal helps your body digest food more steadily, keeping energy levels stable and reducing the chances of a glucose spike.
Avoid Sugary Drinks
Sugary drinks like soda, sweetened teas, and fruit juices can increase blood sugar levels rapidly because they contain simple carbohydrates (sugar) without accompanying fiber, fat, or protein. This means they will absorb into the bloodstream very quickly after drinking. Try swapping sugary drinks for water, unsweetened teas, sparkling water, or water infused with different fruits.
Learn How to Snack
If you find yourself hungry in-between meals or have to wait awhile before your next meal, go ahead and reach for that snack. Try to avoid heavily processed foods that are high in sugar and refined carbs—like candy and chips—and instead choose something that contains fiber, healthy fat, and protein. Or you can simply add those things to what you have. This can look like having a handful of nuts with your carby snack, adding some nut butter, or having some Greek yogurt with berries on the side.
Get Active
Taking a walk after a meal can help your body regulate blood sugar levels more effectively. It encourages your muscles to use glucose for energy, which can prevent blood sugar spikes and help maintain steady energy levels, especially after a carb-heavy meal.
Blood sugar regulation isn’t just for people with diabetes—it’s essential for everyone who wants more stable energy, better mood, and long-term health. By understanding how blood sugar works and making small changes to your diet, you can help maintain your body’s natural balance and feel your best.
