The Glycemic Index (GI) and Its Impact on Blood Sugar
The glycemic index (GI) indicates how quickly carbohydrates are converted into glucose. Foods with a high GI lead to a rapid increase in blood sugar levels, while those with a low GI cause a slower rise.
Honey’s GI and Its Effects on Blood Sugar
Although honey, a natural sweetener made of glucose and fructose, has a higher GI than table sugar, it may have a lesser impact on blood sugar levels.
Factors Affecting Honey’s GI

The GI of honey varies depending on the type, processing, and quantity consumed. Generally, lighter honeys and raw honey tend to have lower GIs.
Benefits of Honey for Diabetics

Despite having a higher GI, honey provides antioxidants and may assist in controlling blood sugar levels. Certain types, such as Manuka and buckwheat honey, have lower GIs.
Precautions for Diabetic Honey Consumption
- Regularly monitor blood sugar levels.
- Opt for honey with a lower GI.
- Use honey moderately to prevent sudden spikes in blood sugar.
Including Honey Safely in a Diabetic Diet
Choosing honey with a lower GI and consuming it in moderation can be advantageous. Honey can be a substitute for refined sugar in various recipes.
Health Benefits and Precautions of Honey Consumption
While honey may offer health benefits like allergy relief and a reduced risk of heart disease, it is crucial to use it sparingly due to its sugar content.
About Honey and Glycemic Index
Honey, a natural sweetener with a lower GI than table sugar, could be a healthier option for individuals with diabetes. Studies suggest that honey causes smaller spikes in blood sugar compared to other sweeteners.
Honey, being sweeter than white sugar, leads to a lesser increase in blood sugar levels after consumption. Research indicates that honey can enhance insulin production and sensitivity, potentially reducing blood sugar in people with diabetes. While the GI of a food is important, how the body metabolizes it also relies on the meal context. The polyphenols in honey assist in balancing gut bacteria and reducing inflammation, benefiting heart health.
Health benefits of honey
Darker honey contains higher levels of polyphenols and may improve blood fat levels, lowering the risk of heart disease. Local raw honey might alleviate symptoms of allergic rhinitis. Further research is required as there are limited long-term studies on honey consumption.
Importance of eating in moderation
Honey is a preferable choice over white sugar for individuals with diabetes, although it still raises blood sugar levels. Ensure that the honey is 100% pure to avoid added sweeteners. A well-rounded diet comprising protein, healthy fats, and fiber-rich carbohydrates is crucial for managing blood sugar levels.

Abstract

Recent studies suggest that honey could serve as a potential antidiabetic agent, offering benefits for diabetes management and its associated complications.
1. Introduction
Diabetes, a metabolic disorder with various causes, impacts millions globally. The medicinal properties of honey may aid in managing diabetes alongside conventional medical treatments.
There has been a misconception regarding the suitability of honey in the diet of individuals with diabetes due to its high carbohydrate content. A review of numerous literature studies aims to address whether honey can be a viable sugar substitute in a diabetic diet. Research indicates the possible effects of honey on diabetes.
The fructose content in honey varies, with studies suggesting a hypoglycemic effect. Fructose may reduce blood glucose levels in individuals with diabetes through mechanisms such as decreased absorption rates and stimulation of liver functions.
Studies have explored the effects of fructose on glycemic control and body weight. In animal models such as rats, fructose has demonstrated the ability to enhance glucose regulation and insulin response, indicating potential advantages.
Animal models, including rats induced with streptozotocin and alloxan, have been utilized to study honey’s hypoglycemic effects. Research on rats fed diets containing honey has shown encouraging results in weight management and improved cholesterol levels.
In both healthy rats and those induced with diabetes, honey has exhibited a hypoglycemic effect. It has also enhanced the antihyperglycemic properties of standard antidiabetic medications, suggesting its potential as a treatment for diabetes.
Overall, preclinical studies on animal models support the positive impact of honey on diabetes mellitus. Further research is required to comprehensively understand its mechanisms and potential therapeutic applications.

Importance of a Well-Balanced Diet
It is essential for human beings to consume all the necessary nutrients such as water, proteins, lipids, carbohydrates, vitamins, minerals, amino acids, and bioactive compounds to support life. Maintaining a healthy and balanced diet is vital for overall well-being. Any imbalances in metabolism, whether from a lack or an excess of nutrients, can result in various health problems.
One such health issue is diabetes, which is characterized by high blood sugar levels due to insufficient insulin production. Research on animals indicates that including honey in the diet can aid in managing diabetes and its complications. Limited studies on humans, both healthy individuals and those with diabetes, have shown beneficial effects of consuming honey.
Al-Waili’s research highlighted that adding honey to the diets of healthy individuals, diabetes patients, and those with hypertriglyceridemia led to improved lipid profiles, reduced inflammation markers, and better control of blood sugar levels. In comparison to refined sugar, honey resulted in lower spikes in blood sugar.
Unlike sugar, which is a highly processed product mainly composed of sucrose and widely utilized in the food industry, honey is a natural sweetener with a complex composition. It has a lower glycemic index and energy value than sugar. The chemical makeup of honey can vary based on its botanical and geographical origins.
A table comparing the chemical composition of honey to sugar is provided in Table 2. Honey contains fewer calories, less sugar, and higher levels of essential nutrients like vitamins and minerals in comparison to sugar.

Research on the Effects of Honey on Blood Sugar Levels
※ The data on honey values are based on averages from various honey varieties.
Honey has a unique composition with high fructose content, which could potentially have a positive impact on blood sugar levels. Fructose promotes the absorption and storage of glucose in the liver, aiding in the control of blood glucose levels.
An encouraging clinical study involving twenty individuals with type 2 diabetes who replaced their medication with honey showcased promising outcomes in managing the condition, as detailed in Table 3.
Exploring the Effects of Honey on Individuals with Diabetes
| Reference | Studies Teams | Treatment Plans with Honey/Sugars | Achieved Outcomes |
|---|---|---|---|
| [16] | 17 participants in the control group 38 participants in the experimental group |
During the study, the control group consumed 70g of sucrose daily for 30 days, while the experimental group consumed 70g of honey. | The consumption of honey resulted in a slight decrease in body weight (1.3%) and body fat (1.1%), as well as reductions in total cholesterol (3%), LDL-C (5.8), triacylglycerol (11%), FBG (4.2%), and CRP (3.2%), with an increase in HDL-C (3.3%) among healthy individuals. Patients experienced reductions in total cholesterol by 3.3%, LDL-C by 4.3%, triacylglycerol by 19%, and CRP by 3.3% due to honey consumption. |
| [31] |
| Study on 48 patients with type II diabetes: Experimental group with honey Control group |
| The experimental group consumed honey at a dose of 1 g/kg BW/day for the first 2 weeks, followed by 1.5 g/kg BW/day for the next 2 weeks, then 2 g/kg BW/day for the subsequent 2 weeks, and finally 2.5 g/kg BW/day for the last 2 weeks |
| The honey group showed significant reductions in body weight, total cholesterol, LDL-C, and triglycerides, as well as a significant increase in HDL-C. Additionally, levels of hemoglobin A1C significantly increased in the honey group. |
| [36] |
| 24 individuals in good health, 16 individuals with type II diabetes 6 individuals with high blood pressure |
| 12 healthy participants underwent inhalation therapy with distilled water for 10 minutes initially; a week later, they were given a honey solution (60% wt/v) for the same duration. Another group of 12 healthy individuals received inhalation therapy with 10% dextrose for 10 minutes. |
| The inhalation of honey resulted in a significant decrease in random blood glucose levels from 199+/−40.9 mg/dl to 156+/−52.3 mg/dl after 30 minutes. Fasting blood glucose levels remained lower for up to 3 hours post-inhalation. During the glucose tolerance test, the intensity of hyperglycemia was significantly reduced following honey inhalation. |
| [78] |
| Study participants: 48 individuals, including those who were healthy, diabetic, and had hyperlipidemia |
|
Findings:
|
| [88] | 50 individuals diagnosed with type I diabetes 30 individuals without diabetes |
| Dosage of honey: 1.75 grams per kilogram of body weight Dosage of sucrose: 1.75 grams of sugar per kilogram of body weight |
|
| The Glycemic Index (GI) and Postprandial Insulinemic Index (PII) levels of sucrose and honey showed no significant differences between the diabetic patients and the control group. However, both the GI and PII levels of honey were notably lower compared to sucrose in both the patients and controls. Moreover, in both the diabetic patients and controls, there was a significant increase in C-peptide levels after honey consumption, compared to glucose or sucrose. |
In addition to the glycemic index (GI), peak incremental index (PII) is utilized to evaluate the glycemic impact of various foods on blood glucose levels [81].
C-peptide is recognized as a reliable indicator of insulin secretion, co-secreted with insulin as a by-product of pancreatic cells without any biological activity of its own [82], resulting from the enzymatic breakdown of proinsulin into insulin. Studies examining the effects of honey on insulin and C-peptide levels in both healthy and diabetic individuals have yielded conflicting results [54, 83, 84].
A study conducted at the National Institute of Diabetes in Cairo, Egypt, involving twenty diabetic youths and ten non-diabetic individuals aimed to clarify this discrepancy [73]. Glucose, sucrose, and honey solutions were diluted in 200 ml of water based on the participant’s weight (amount of sugar/honey = subject’s weight in kg × 1.75, with a maximum of 75 g). Each participant ingested the diluted sugars and honey in the morning, one week apart for each type, with the entire testing period lasting three weeks. Blood samples were collected before consumption and at 30-minute intervals after ingestion until 120 minutes (2 hours). The serum C-peptide level and blood glucose levels were analyzed in all samples.
Both the patients and the control group exhibited lower glycemic index and peak incremental index values when honey was consumed compared to glucose and fructose, although the C-peptide levels differed between the two groups.
The consumption of honey may have a positive impact on plasma C-peptide levels in non-diabetic individuals, promoting the activation of pancreatic beta cells [73]. Despite a lower GI compared to sugar (Table 2), the GI of honey varies depending on the fructose/glucose ratio [85, 86]. Different varieties of honey have shown varying effects on glucose levels in different studies [85]. Honey consumption has been associated with weight loss and improved blood glucose control in both healthy individuals and diabetics when compared to sugar [31]. Research suggests that honey can contribute to hypoglycemic effects [12, 33]. Additionally, honey has shown potential in managing diabetic wounds, aiding in the healing process due to its antioxidant and antimicrobial properties [75, 92–93].
Numerous studies worldwide have demonstrated the effectiveness of honey in treating diabetic wounds, reducing pain, and accelerating the healing process [100–105]. Specifically, Manuka honey has shown promising results in wound healing [106]. Guidelines recommend the use of natural, unheated honey stored in dark glass containers for wound treatments [99]. Experimental studies have indicated the potential benefits of honey in diabetes management, including controlling blood glucose levels and reducing metabolic disorders [107]. However, further research, involving larger sample sizes and longer durations, is essential to confirm its efficacy in diabetes management.
