Maintaining balanced blood sugar levels is crucial for people with diabetes. However, at times, blood sugar levels can dip too low, leading to a condition known as hypoglycemia. When this happens, it’s vital to act quickly to raise blood sugar levels to a safe range. One of the best ways to address low blood sugar is by eating foods that can quickly and effectively raise glucose levels.
This article aims to provide an in-depth understanding of what to eat to raise low blood sugar, the types of foods to choose, and why these foods work. Whether you have diabetes or need to assist someone in managing hypoglycemia, understanding the right dietary choices for raising blood sugar can make a significant difference in overall health and safety.
What is Low Blood Sugar (Hypoglycemia)?
Before we delve into the foods that can help raise low blood sugar, it’s essential to understand what hypoglycemia is and how it occurs. Hypoglycemia refers to abnormally low blood sugar levels, typically under 70 mg/dL (milligrams per deciliter), though the exact threshold may vary based on an individual’s health status.
Blood glucose is the body’s primary energy source, especially for the brain. When glucose levels fall too low, individuals may experience symptoms such as shaking, sweating, dizziness, confusion, and in extreme cases, loss of consciousness. This is why it is crucial to take action to raise blood sugar levels when they fall too low.
Hypoglycemia can be triggered by several factors, including:
-
Excessive insulin use in individuals with diabetes
-
Skipping meals or not eating enough
-
Physical activity without proper adjustments in diet or medication
-
Excessive alcohol consumption without eating
-
Certain medications and health conditions
The goal in managing low blood sugar is to restore normal levels as quickly and safely as possible.
What to Eat to Raise Low Blood Sugar: The Basics
When faced with low blood sugar, it’s essential to consume foods that are fast-acting sources of glucose. The body absorbs simple carbohydrates quickly, making them the most effective choice for raising blood sugar. However, not all carbohydrates are created equal. Some sources of carbs act more rapidly than others, and some foods contain other nutrients that can help stabilize blood sugar over time.
The general rule for treating low blood sugar is to consume about 15 grams of fast-acting carbohydrates and then wait 15 minutes to check blood sugar levels. If the blood sugar is still low, repeat the process.
Here are the main categories of foods and drinks that can help raise blood sugar when it’s low:
Fast-Acting Carbohydrates: The First Step in Treating Low Blood Sugar
1. Glucose Tablets
Glucose tablets are one of the most efficient ways to raise low blood sugar. These tablets contain a concentrated amount of glucose, which is absorbed quickly into the bloodstream. Most glucose tablets are available in 4-gram increments, and you can take up to 4 tablets at once to reach the 15-gram threshold recommended for treating hypoglycemia.
Why it works: Glucose is a simple sugar that is rapidly absorbed by the body and does not require digestion. This makes glucose tablets the fastest and most effective option for quickly raising blood sugar.
2. Fruit Juice
Fruit juice, especially orange juice, is another quick option for raising blood sugar. A half-cup (4 ounces) of fruit juice typically contains about 15 grams of carbohydrates, making it an ideal choice for treating mild to moderate hypoglycemia.
Why it works: Fruit juices are primarily composed of natural sugars, which are rapidly absorbed into the bloodstream. The sugar in fruit juice provides a fast-acting source of energy that the body can use to stabilize blood sugar levels.
3. Regular Soda (Not Diet Soda)
Regular sodas that contain sugar can also quickly raise blood sugar levels. About 4 ounces of soda (half a can) contains around 15 grams of carbohydrates. It’s important to use regular soda, as diet sodas contain artificial sweeteners that do not raise blood sugar.
Why it works: The sugar in regular soda, like fruit juice, is quickly absorbed by the body, providing an immediate boost in blood sugar levels.
4. Honey or Syrup
One tablespoon of honey or syrup typically provides about 15 grams of carbohydrates. You can consume the honey or syrup directly or mix it with water for easier consumption.
Why it works: Honey and syrup are both simple sugars, meaning they don’t require much digestion before being absorbed into the bloodstream, making them effective for quickly raising blood sugar.
Other Useful Foods to Raise Low Blood Sugar
While the above options are excellent for quick fixes, it’s important to follow up with a more substantial meal or snack that includes a balance of carbohydrates, protein, and fats to prevent blood sugar from dipping again too quickly.
5. Fruit
Whole fruits such as apples, bananas, grapes, and berries contain natural sugars that can raise blood sugar levels. However, they are slower to act than liquids like juice or soda. Eating one small piece of fruit (like an apple or banana) can provide around 15 grams of carbohydrates.
Why it works: Fruit contains natural sugars (like fructose) and fiber, which helps to provide a steady, slower release of glucose into the bloodstream. Fruits with higher glycemic indexes, such as bananas, may raise blood sugar a bit faster.
6. Dried Fruit
Dried fruit, such as raisins or apricots, is another source of quick-acting sugar. A small handful (about 1 ounce) of dried fruit contains around 15 grams of carbohydrates, making it a convenient snack to raise blood sugar.
Why it works: Dried fruit is rich in natural sugars and can be consumed in a concentrated form, meaning it’s a portable and quick option when you’re in a bind.
7. Graham Crackers or Plain Crackers
While they aren’t as fast-acting as glucose tablets or juices, plain crackers such as graham crackers can still help raise blood sugar. They contain simple carbohydrates, but they should be eaten in combination with a small amount of protein or fat to prevent blood sugar from dropping again too quickly.
Why it works: The carbohydrates in crackers are digested and absorbed into the bloodstream, gradually raising blood sugar. A small portion is sufficient to help bring levels back to normal.
8. Milk
Milk contains lactose, a natural sugar, and also provides some protein. A small glass of milk (about 4 ounces) contains roughly 12 grams of carbohydrates. Although milk isn’t as fast-acting as glucose tablets or fruit juice, it’s an effective option when you’re unable to find quicker alternatives.
Why it works: The combination of lactose and protein in milk provides both an immediate and sustained rise in blood sugar, helping stabilize glucose levels over time.
Why These Foods Work: Understanding Carbohydrates and the Glycemic Index
Carbohydrates are the body’s primary source of glucose, and the glycemic index (GI) is a measure of how quickly different foods raise blood sugar levels. Foods with a high GI, such as glucose and fruit juices, raise blood sugar rapidly. Foods with a lower GI, such as whole fruits or crackers, provide a more gradual increase in blood sugar levels.
In cases of hypoglycemia, it’s essential to choose foods with a high GI initially to raise blood sugar quickly. Once the immediate symptoms are alleviated, foods with a lower GI, like whole grains or protein-rich snacks, can be consumed to stabilize blood sugar and prevent it from dipping again.
What to Avoid When Raising Blood Sugar
While it’s important to choose the right foods to raise blood sugar, it’s equally important to know what not to eat when dealing with hypoglycemia:
1. Avoid Diet Sodas or Sugar-Free Foods
Diet sodas and sugar-free foods contain artificial sweeteners that do not raise blood sugar. While they may be fine for people managing their blood sugar in the long term, they are ineffective for treating hypoglycemia.
2. Avoid High-Fat Foods
Foods that are high in fat, such as chocolate or nuts, can delay the absorption of glucose because fat slows down digestion. Although they may be useful for stabilizing blood sugar levels once they’re back in the normal range, they are not recommended for treating low blood sugar in the moment.
What to Do After Raising Low Blood Sugar
After treating low blood sugar, it’s essential to take steps to prevent it from happening again. Follow-up actions may include:
Check blood sugar again after 15 minutes to ensure it’s back within a safe range.
Eat a balanced meal containing carbohydrates, protein, and healthy fats to help stabilize blood sugar and prevent it from dropping again.
Avoid physical activity immediately after treating hypoglycemia, as exercise can lower blood sugar further.
Conclusion
When blood sugar drops too low, it’s essential to act quickly to restore normal levels. Fast-acting carbohydrates, such as glucose tablets, fruit juice, and regular soda, are the most effective foods for raising blood sugar. After stabilizing glucose levels, it’s crucial to follow up with a balanced meal to maintain steady blood sugar throughout the day.
For individuals with diabetes, managing blood sugar is a continuous process that requires careful monitoring, knowledge, and planning. Understanding the right foods to eat to raise low blood sugar is an essential part of diabetes care, ensuring both immediate relief and long-term health.
