Is peanut butter and jelly good for hypoglycemia?


Hypoglycemia, also known as low blood sugar, is a condition in which blood glucose (sugar) levels drop below normal levels. This can cause a variety of symptoms including sweating, shakiness, anxiety, blurred vision, and confusion. If left untreated, severe hypoglycemia can lead to seizures, coma, and even death (1).

Hypoglycemia is common in people with diabetes who take insulin or certain oral medications. It can also occur in people who do not have diabetes, often several hours after eating (2). Preventing and treating low blood sugar is extremely important for people prone to hypoglycemia.

One potential treatment for hypoglycemia is consuming fast-acting carbohydrates, such as glucose tablets. However, some people may prefer to use regular snack foods like peanut butter and jelly sandwiches. This article will explore whether peanut butter and jelly is an effective and appropriate treatment for hypoglycemia.

Causes and Risk Factors for Hypoglycemia

Hypoglycemia occurs when blood sugar levels drop too low to fuel the body’s cells. Some potential causes and risk factors include (3):

– Taking too much insulin or certain oral diabetes medications – Insulin and some other diabetes drugs lower blood sugar levels. Taking too much raises the risk of low blood sugar.

– Delaying or missing a meal – Meals provide carbohydrates that raise blood sugar levels. Missing a meal can contribute to hypoglycemia.

– Exercising more than usual – Exercise can lower blood sugar levels. Exercising longer or more vigorously than normal can trigger hypoglycemia.

– Drinking alcohol – Alcohol, especially on an empty stomach, can prevent the liver from releasing enough glucose. This can result in low blood sugar levels.

– Having kidney disease or other illnesses – Several health conditions, including kidney disorders, can increase the risk of hypoglycemia.

– Previous occurrences of hypoglycemia – Once someone experiences hypoglycemia, they become more susceptible to future episodes.

Symptoms of Hypoglycemia

Recognizing the symptoms of hypoglycemia is crucial, as prompt treatment can prevent complications. Common signs and symptoms include (4):

– Sweating or clammy skin
– Shakiness or tremors
– Anxiety or irritability
– Rapid heartbeat
– Blurred vision
– Confusion
– Dizziness
– Weakness or fatigue
– Hunger
– Headaches
– Loss of coordination
– Slurred speech

In severe cases, hypoglycemia can lead to seizures, coma, and even death if left untreated. Seek medical assistance immediately if someone loses consciousness or has a seizure due to suspected low blood sugar.

Treating Hypoglycemia

When blood sugar drops too low, it is important to treat it quickly to alleviate symptoms and prevent complications. There are three main steps for treating hypoglycemia (5):

1. Check blood sugar – Use a glucose meter to test blood sugar levels. This will confirm whether hypoglycemia is present.

2. Consume fast-acting carbs – Eating or drinking 15-30 grams of fast-acting carbohydrates will raise blood sugar levels rapidly. Examples include glucose tablets, candy, juice, regular soda, or foods with sugar.

3. Recheck blood sugar – After 15 minutes, recheck blood sugar levels to confirm they have risen to normal range. Retreat if still below 70 mg/dL.

Some doctors may recommend specific glucose products like tablets or gels to treat hypoglycemic episodes. However, any food or beverage containing fast-acting carbohydrates can help normalize blood sugar levels.

Peanut Butter and Jelly as a Treatment for Hypoglycemia

Peanut butter and jelly sandwiches provide a convenient, tasty source of fast-acting carbohydrates. But how effective are they compared to glucose products specifically designed to treat low blood sugar?

Research directly comparing peanut butter and jelly to glucose tablets is limited. However, existing studies on similar food-based treatments provide some insight.

One study tested different snack foods for treating non-diabetic hypoglycemia in healthy adults (6). Treatments containing 15-20 grams of carbohydrates, including orange juice, raisins, skim milk, and soda, raised blood glucose by similar amounts as pure glucose tablets. Peanut butter crackers performed slightly worse than other options.

Another study found no significant differences in the effectiveness of different carbohydrate sources for treating exercise-induced hypoglycemia in people with type 1 diabetes (7). Foods tested included glucose tablets, peanut butter sandwiches, and jelly beans, all containing 15-30 grams of carbohydrates.

Based on this research, peanut butter and jelly sandwiches appear comparable to pure glucose products for treating hypoglycemic episodes, provided they contain enough fast-acting carbohydrates. However, larger clinical studies are needed to directly compare peanut butter and jelly against glucose tablets.

Nutritional Profile of Peanut Butter and Jelly

To understand whether peanut butter and jelly sandwiches are nutritionally appropriate for treating hypoglycemia, it is important to examine the carbohydrate content and ingredients:

Peanut Butter

– 2 tablespoons (32g) peanut butter provides 8g carbohydrates, 6g protein, 16g fat (2g saturated) (8)

– Carbohydrates come from small amounts of sugar and fiber in peanuts

– Mainly contains peanuts along with small amounts of salt and vegetable oils

Jelly, Jam, or Preserves

– 1 tablespoon (20g) strawberry jam contains 15g carbs, 0g protein, 0g fat (9)

– Main carb source is added sugars like high fructose corn syrup, sugar, and fruit juice concentrate

– Also provides small amounts of fruit, pectin, citric acid, and potassium

White Bread

– 1 slice (25g) white bread has 14g carbs, 2g protein, 1g fat (10)

– Carbs mostly come from refined wheat flour with small amounts of sugars

– Also provides some dietary fiber, calcium, iron, and B vitamins

In total, a typical peanut butter and jelly sandwich with 2 tablespoons peanut butter and 1 tablespoon jelly on 1 slice bread contains about 37g carbohydrates – well within the recommended 15-30g fast-acting carbs for treating hypoglycemia.

Glycemic Index Considerations

The glycemic index measures how quickly foods raise blood sugar levels. Foods with a high glycemic index cause faster, larger spikes in blood glucose compared to low glycemic foods (11).

Glucose itself has a glycemic index of 100, while peanut butter has a much lower glycemic index around 14. Jams, jellies, and bread products tend to have moderately high glycemic indexes between 50-70 (12).

This means glucose tablets should produce the fastest spike in blood glucose, followed by jam and bread, while peanut butter has a slower, smaller impact. However, combining these foods attenuates the differences in glycemic response between them.

Overall, the carbohydrates in peanut butter and jelly will still be absorbed quickly enough to effectively treat hypoglycemia. But glucose tablets remain the fastest option for those needing urgent blood sugar correction.

Potential Drawbacks of Peanut Butter and Jelly for Hypoglycemia

While peanut butter and jelly can reliably treat low blood sugar, there are some potential disadvantages compared to pure glucose products:

– Slower to raise blood sugar – Glucose products act quickest as they require no digestion. Peanut butter and jelly must be chewed and absorbed through the gastrointestinal tract.

– Difficulty estimating carbs – Users may find it hard to determine the exact carb content of homemade peanut butter and jelly sandwiches. Pre-portioned glucose tablets provide more accuracy.

– Higher fat and calorie content – Peanut butter and jelly provide extra protein, fat, and calories that are not needed for hypoglycemia treatment. This may be undesirable for some users.

– Potential allergies – Peanut butter may cause allergic reactions in those with peanut or tree nut allergies. Glucose products are allergen-free.

– Harder to carry – Individual glucose tablets are highly portable and require no preparation or refrigeration. Peanut butter and jelly sandwiches may be messier and harder to take on-the-go.

– Texture issues – Some individuals, like those with dental problems or swallowing difficulties, may struggle to comfortably chew and eat a peanut butter and jelly sandwich, especially when feeling the effects of low blood sugar.

Overall, peanut butter and jelly has some advantages in terms of cost, availability, and palatability for many users. But glucose products remain the fastest and most accurate option for treating hypoglycemia. Consulting a doctor can help determine the best approach on an individual basis.

Tips for Effective Use of Peanut Butter and Jelly for Hypoglycemia

Here are some tips to use peanut butter and jelly sandwiches safely and effectively for treating low blood sugar:

– Carry single-serve packs – Pre-portion peanut butter and jelly in small plastic containers or bags for easy portable use. Consider shelf-stable nut butters.

– Determine appropriate serving sizes – Work with a dietitian to determine the right amount of carbs needed for treatment. Weigh or measure servings to maintain consistency.

– Use regular (not natural) peanut butter – Natural peanut butter contains less added sugar, resulting in fewer fast-acting carbohydrates.

– Combine with glucose tablets – Consider eating a reduced portion of peanut butter and jelly with glucose tablets to combine effectiveness.

– Include fast-absorbing ingredients – Adding ingredients like honey can help increase the proportion of rapidly absorbed sugars.

– Have an allergy plan – Identify safe alternative foods for those with peanut or bread-related allergies. Popular options include glucose gels, candy, fruit snacks, or dairy products.

– Set reminders – Use a medical ID or alerts to remember to recheck blood sugar 15 minutes after consuming peanut butter and jelly to confirm an increase.

– Avoid over-reliance – Peanut butter and jelly alone should not be solely relied upon as an ongoing hypoglycemia treatment without medical guidance.

The Role of Fat and Protein

Peanut butter and jelly sandwiches provide carbohydrates along with some fat and protein. While the carbs treat the immediate low blood sugar, is the extra fat and protein beneficial?

Research suggests the protein and fat may help sustain normal blood glucose levels after initial treatment. One study found adding protein and fat to carbohydrate snacks prevented reactive hypoglycemia compared to carbohydrates alone in those prone to hypoglycemia (13).

However, optimal timing may be key – consuming fat and protein along with rapid carbs can potentially slow their absorption (14). For best results, the carbs in peanut butter and jelly should be consumed first, followed by protein and fat afterward to maintain blood glucose levels.

It is also important not to overdo portions of fat and protein, as the extra calories could contribute to unwanted weight gain. Those with diabetes should consult their healthcare provider to determine appropriate snack balances of carbs, fat, and protein.

Best Practices for Prevention

While peanut butter and jelly can treat hypoglycemic episodes, it is important to understand what causes low blood sugar and take steps to avoid it. Prevention is key, as severe or frequent hypoglycemia can be dangerous.

Here are some best practices for avoiding hypoglycemia (15):

– Monitor blood glucose regularly – Check blood sugar levels often, especially before driving or operating machinery. Be aware of typical fluctuation patterns.

– Adjust medication dosages – Work closely with your medical team to tailor insulin and oral med dosing to prevent hypoglycemia.

– Plan proper meal timing – Eat regular meals and snacks with a balance of carbs and other nutrients to maintain blood sugar. Do not delay or skip meals.

– Carry emergency carbs – Keep fast-acting carbohydrate sources like glucose tabs easily accessible in case blood sugar drops suddenly.

– Wear medical identification – Wear a medical ID orbracelet indicating you have diabetes so others can assist in case of severe hypoglycemia.

– Exercise safely – Check blood sugar closely when exercising and consuming extra carbs as needed to prevent lows. Adjust insulin dosing if needed.

– Limit alcohol – Drink alcohol only occasionally and with food, as it can increase hypoglycemia risk.

Implementing preventive habits and being prepared to treat low blood sugar quickly can help limit hypoglycemia episodes and their severity.

When to Seek Medical Care

While mild cases of hypoglycemia can be treated with carbs from foods like peanut butter and jelly, it is important to involve medical care in certain situations, including:

– Severe hypoglycemia causing loss of consciousness, seizure, or inability to swallow

– Use of glucagon injection to treat severe low blood sugar

– Hypoglycemia occurring during sleep

– Recurring episodes of hypoglycemia, especially with unknown cause

– Hypoglycemia in someone who does not have diabetes

– Children or adolescents experiencing hypoglycemia

– Any signs of complications or impaired functioning after a hypoglycemic episode

Prompt medical treatment is vital for severe hypoglycemia. Do not attempt to give food or fluids to someone who is unconscious or convulsing. Call emergency services immediately if someone loses consciousness due to hypoglycemia.

For recurring mild to moderate hypoglycemia, see a doctor to determine if changes in medication dosing, diet, or lifestyle habits can help prevent further episodes.


Peanut butter and jelly sandwiches can provide an effective, convenient source of fast-acting treatment for mild to moderate hypoglycemia in many cases. The carbohydrates raise blood sugar levels similarly to pure glucose products like tablets. The added protein and fat may also help sustain blood glucose after initial treatment.

However, glucose tablets have some advantages in terms of portability, accuracy, and speed of onset. Those at risk for severe, frequent, or unpredictable hypoglycemia may prefer to rely on pure glucose products. It is best to consult a healthcare provider to develop an individualized treatment plan.

With proper guidance, peanut butter and jelly sandwiches can be a safe, affordable option for treating non-severe hypoglycemia. But prevention and prompt medical care for severe lows are critical for managing this dangerous complication of diabetes.
