Honey is always associated in our minds with countless health and therapeutic benefits. Who among us has not turned to a warm spoonful of honey on a winter night to soothe a nagging cough, used it daily to boost their children's immunity, or even as an ideal substitute for white sugar to maintain health?
However, behind this sweet taste and good reputation, there is another side we rarely talk about: the side effects of honey that many overlook. Despite its purity, honey can cause some side effects and complications, whether due to excessive consumption or falling into the trap of adulterated and unreliable types.
It is natural to feel confused and ask: Does honey raise blood sugar? Can a daily spoonful harm the liver in the long run? Are all types of honey as safe as we think? And when does honey become harmful instead of a cure? In the following lines, we discover together the definitive answers to all these questions quite simply.
What are the Side Effects of Honey?
Despite the many benefits of honey, its side effects include increased calorie intake, elevated blood sugar, allergies, digestive disorders, and poisoning in infants, in addition to risks associated with certain types of honey or adulterated products. Here are the details as follows:
Weight Gain and Fat Accumulation
Many believe that replacing white sugar with honey gives them the freedom to consume it in unlimited quantities. However, the truth is that honey remains a concentrated source of carbohydrates and simple sugars such as fructose and glucose.
A single tablespoon of honey (about 21 grams) contains approximately 64 calories, which is higher than the calories found in the same amount of white sugar.
When consumed excessively on a daily basis, the body absorbs amounts of sugar that exceed its immediate energy needs, prompting the liver to convert this excess into triglycerides stored in body cells, causing weight gain and fat accumulation, especially in the abdominal area.
Blood Sugar Fluctuations
Blood glucose levels are directly affected by honey consumption, as honey has a glycemic index (a measure of how quickly sugar rises in the blood) ranging from medium to high, at about 58 points.
The reason for the rise in sugar after consuming honey is its content of fast-absorbing sugars that flow into the bloodstream immediately after digestion. Here, the fundamental difference between natural and adulterated honey appears.
Natural honey contains minerals and antioxidants that slow down this process relatively compared to pure sugar, while adulterated honey (mixed with glucose syrup or synthetic fructose) lacks these nutrients, causing sudden and sharp spikes in sugar levels, placing significant stress on the pancreas.
Risk of Contamination or Poisoning
Honey is a natural product directly affected by its surrounding environment, making it susceptible to certain types of chemical contamination during production stages or due to unhygienic storage.
Pesticide Residues in Honey
Contamination is transferred to honey when bees absorb nectar from flowers sprayed with chemical pesticides in surrounding farms. The danger of these residues lies in their long-term accumulation in the human body when this honey is consumed regularly, negatively affecting the nervous and immune systems.
Traces of Antibiotics
Some unprofessional beekeepers resort to using antibiotics to protect hives from bacterial diseases. This practice leads to the transfer of traces of these antibiotics to the honey, and their consumption by humans triggers allergic reactions, in addition to contributing to increased bacterial resistance to antibiotics.
Infant Botulism Risk
The risk of botulism is the primary reason behind the strict medical warning against giving honey to infants and children under one year of age. Natural honey contains spores of a bacterium called Clostridium botulinum. Since an infant's digestive system and intestines are not yet fully developed and do not possess enough acidity or beneficial bacteria to resist these spores, they grow inside their intestines and secrete dangerous neurotoxins.
Symptoms of this poisoning include: severe constipation, total lethargy, weak sucking ability, muscle weakness, and life-threatening breathing difficulties.
Allergic Reactions (Triggering Allergies)
Since honey is made from flower nectar, it naturally carries residues of pollen and minute parts of bee secretions.
For people suffering from pollen allergies (seasonal or chronic), allergy symptoms appear as mouth itching, skin rash, swelling of the lips or tongue, and a runny nose. This condition becomes extremely dangerous and requires immediate medical intervention if it develops into what is known as anaphylactic shock, which includes symptoms such as severe shortness of breath, extreme dizziness, and a drop in blood pressure.
Digestive Issues
Honey contains a high percentage of fructose sugar. When consumed in large quantities, the digestive system faces difficulty in fully absorbing this sugar in the small intestine. Unabsorbed fructose moves to the large intestine, where it is fed upon by the flora (natural bacteria), causing rapid fermentation that results in bloating, unpleasant gases, cramps, abdominal colic, and diarrhea due to the sugar drawing water into the intestines.
The severity of these symptoms increases significantly in patients with Irritable Bowel Syndrome (IBS), as their intestines are more sensitive to foods rich in fermentable sugars.
Mad Honey Poisoning
Mad honey is a type of wild honey produced by bees after feeding on the nectar of a specific species of Rhododendron plants. This honey contains natural toxins known as grayanotoxins, which directly affect the nervous system and the heart.
Symptoms of poisoning include: severe dizziness, nausea, a sharp drop in blood pressure, slowed heart rate, and in severe cases, it can lead to hallucinations and loss of consciousness. There are many recorded cases of poisoning globally due to its consumption, mostly concentrated in regions of Turkey and Nepal.
Honey Side Effects and Potential Complications
The most prominent fast-appearing side effects that any person may face as a result of consuming unsuitable honey, excessive amounts, or due to individual sensitivity include the following:
- Nausea: Occurs due to high viscosity and concentrated density in the stomach.
- Dizziness and Headache: Directly related to the sudden rise and then rapid fall of blood sugar levels.
- Digestive Disturbances: Represented by colic, gas, and temporary heartburn.
- Local Allergy: Such as a slight itch in the throat or the immediate appearance of blisters.
Side Effects of Excessive Honey Consumption, High Sugar, and Calories
When we talk about the negative side of honey, the problem does not lie in honey itself as a natural food rich in antioxidants, but is directly related to the quantity consumed. Many of us fall into the trap of dealing with natural products as harmless regardless of the amount, but the balance of health always requires moderation; an overdose turns a healing substance into a burden on the body.
Harm of Excessive Honey (Overconsumption)
We often forget that one spoonful after another quickly leads us to exceed the recommended daily intake of sugars (estimated at about 6 teaspoons for women and 9 for men as a maximum of added and concentrated sugars).
This excess causes the accumulation of simple sugars in the bloodstream, prompting the body to exert double the effort to deal with them. This situation creates an increase in metabolism on the liver and pancreas, as the pancreas is forced to pump massive amounts of insulin continuously and exhaustingly to adjust energy levels in the body.
Harm of Calories Resulting from Honey
It is very easy to consume hundreds of calories without realizing it just by generously adding honey to drinks or baked goods. With repeated and uncalculated consumption throughout the day, these small spoons turn into a massive surplus of energy that exceeds the body's basic needs.
Because the body finds no outlet to burn this extra energy, it inevitably begins to store it as fat in the tissues, causing gradual weight gain and difficulty in maintaining a fit physique.
Raising Blood Sugar Levels
When consuming honey in large quantities, a rapid rise in blood sugar occurs immediately after digestion. This sudden and repeated rise forces cells to be constantly exposed to high doses of insulin.
Over time, cells lose their sensitivity to this hormone, leading to insulin resistance, which is the first step and the gateway toward developing Type 2 diabetes.
Side Effects of Honey for Diabetics
The danger lies in the occurrence of sharp spikes in blood glucose that are difficult to control. Therefore, the importance of calculating carbohydrates accurately arises. If a patient wishes to consume a small teaspoon of honey, its value must be deducted from the carbohydrate portion available to them in the meal to keep the sugar within the safe range.
Side Effects of Honey for Dieting (Effect on Weight Loss)
When honey is introduced into the diet without being accurately calculated within the daily calories prescribed for the diet, it completely hinders weight loss. It may even cause weight stagnation or increase and frustrates all efforts made in burning fat due to the continuous supply of fast-absorbing sugars to the body.
Side Effects of Honey Based on Time, Method of Use, and Mixtures
The issue is not limited to the amount of honey consumed only, but the timing, preparation method, and popular mixtures we mix with it play a pivotal role in determining whether honey will grant us healing or cause a health setback. This is because the incorrect use of some natural ingredients changes their biological nature or doubles their side effects.
Side Effects of Honey Based on Method of Use (Heat and Hot Water)
A common habit is pouring honey into boiling tea or using it in pastries exposed to high temperatures. Scientific fact indicates that high heat destroys the vital compounds and sensitive antioxidants found in honey, causing it to lose its therapeutic value completely and turning it into mere liquid sugar.
Warm water (which is easy to drink immediately) activates honey compounds and facilitates its absorption, while very hot or boiling water causes the breakdown of the natural bonds of honey.
Side Effects of Honey on an Empty Stomach
When honey is consumed on a completely empty stomach, the body absorbs sugars at record speed, which is a sudden shock for diabetic patients, leading to a sharp spike in glucose levels.
As for patients with acid reflux and stomach ulcers, concentrated sugar on an empty stomach stimulates the stomach wall to secrete additional amounts of intestinal acids, causing an immediate feeling of acidity, heartburn, and esophageal irritation instead of soothing it.
Side Effects of Honey Before Bed
Consuming a dose of concentrated sugars like honey just before heading to bed negatively affects sleep quality. The flow of sugar into the blood leads to raising energy levels in some people, causing a state of sudden alertness or insomnia.
In addition, consuming sugar before bed without brushing teeth well leaves a sticky layer that oral bacteria feed on throughout the night, accelerating the process of tooth decay and enamel erosion.
Side Effects of Honey with Milk
Harms appear in special cases, such as people suffering from lactose intolerance, where the mixture causes an increased digestive burden, leading to gas and sharp cramps. Also, this drink is very rich in calories, and continuing it daily causes weight gain.
Side Effects of Cinnamon with Honey
The danger lies in the excessive consumption of cinnamon accompanying honey, especially the Cassia or Chinese cinnamon common in markets. It contains high percentages of a natural substance called coumarin. Excessive daily consumption of this substance causes a direct toxic effect on liver cells and leads over time to liver function disturbance and significant exhaustion.
Side Effects of Apple Cider Vinegar with Honey
The mixture of apple cider vinegar with honey is an acidic mixture par excellence. When consumed regularly, it causes irritation of the mucous membrane lining the stomach, raising rates of acidity and reflux sharply. Also, the strong acids in apple cider vinegar lead to tooth enamel erosion over time.
Side Effects of Consuming Honey with Bread
The meal of bread with honey is one of the beloved traditional meals, but from a nutritional perspective, it forms a heavy composition on the body. This mixture combines the starches in the bread and the concentrated sugars in the honey, raising the sugar in the meal to record levels.
This leads to a sharp spike in blood sugar followed by a rapid drop, making you feel hungry and lethargic shortly after consuming it, as well as increasing the chances of storing excess calories as fat.
Side Effects of Honey Based on Age Group and Health Condition
The body's response to honey varies according to the age stage and the health status of the person. What can be safe and nutritious for a young adult poses a real danger to an infant or a patient suffering from chronic health problems that require a specific diet. Here are the details to pay attention to:
Side Effects of Honey for Children and Infants
Giving honey to infants under one year of age is strictly prohibited because it contains active bacteria that their underdeveloped digestive system cannot fight, which secretes toxins affecting the nervous system.
As for older children, consuming honey in excess leads to early tooth decay due to its viscosity and its clinging to tooth surfaces for long periods.
In addition, the constant increase of sugar in a child's diet releases extra energy that causes obesity, and their taste buds get used to the love of excessive sweets, which keeps them away from eating other healthy foods.
Side Effects of Honey for Pregnant Women
In general, pure natural honey from Al-Mathaq Al-Shafi store is completely safe during pregnancy and does not cause any problems for the mother or the fetus. However, it is preferable to consult a doctor before consuming honey during the months of pregnancy and breastfeeding. Extreme caution must also be taken if the pregnant woman suffers from gestational diabetes or has a predisposition to it.
In this case, consuming honey causes fluctuations in blood glucose levels, posing a risk to fetal growth and excessive weight gain.
Side Effects of Honey for Diabetics and Blood Pressure Patients (Especially those with a single kidney)
Excessive honey causes a rapid rise in sugar, and chronic high sugar leads over time to damage and hardening of small blood vessels, negatively affecting blood flow and arterial pressure.
This deterioration places a massive burden on the single kidney responsible alone for filtering waste and regulating fluids. Hence the importance of moderation and maintaining the therapeutic diets recommended by specialized doctors.
Side Effects of Honey for Dialysis Patients
In the case of kidney failure, the kidneys cannot dispose of excess minerals or deal with dense carbohydrate energy smoothly between dialysis sessions, causing an accumulation of stress substances in the body and placing pressure on the blood circulation. Therefore, it is advised to avoid honey or consult a doctor before tasting it.
Side Effects of Honey for Hemorrhoids
If a person overconsumes honey, and the high fructose sugar in it causes sharp digestive disturbances such as recurrent diarrhea resulting from malabsorption or constipation due to bowel movement disturbance, these digestive disturbances and excretion pressure lead to irritation and inflammation of hemorrhoids.
Side Effects of Honey for the Uterus
There is no evidence proving that pure natural honey harms the uterus in any way; on the contrary, it possesses anti-inflammatory properties.
The only harm that touches the uterus or reproductive health occurs in the case of consuming commercial honey mixtures of unknown source, mixed with unknown herbs, or honey contaminated with chemical residues and pesticides that affect the hormonal balance in the body.
Side Effects of Honey Based on the Organ and Area of Use
The method of using honey, whether by consumption or external topical application, leaves a direct impact on different body organs. Here is how the incorrect or excessive use of honey can affect each organ:
Side Effects of Honey on the Stomach
If the honey is concentrated, high fructose in honey causes difficulty in absorption in the intestines, leading to bloating and gas.
Also, consuming honey intensely and without diluting it stimulates the secretion of intestinal acids, causing acidity and stomach burning.
In case of consuming large quantities at once, the person suffers from sudden diarrhea due to the imbalance of fluids within the digestive tract.
Side Effects of Honey on the Liver (and its effect on liver fat)
When overconsuming honey daily and in excessive quantities, fructose flows to the liver in amounts that exceed its ability to convert it into energy.
This surplus forces the liver to convert sugar directly into triglycerides. With the continuation of this process, these fats begin to accumulate inside the cells of the organ itself, contributing directly to Non-Alcoholic Fatty Liver Disease (NAFLD).
Side Effects of Honey on the Kidneys
A kidney patient needs extreme caution for two reasons. The first is that advanced kidney disease requires strict monitoring of carbohydrate and mineral levels in honey. The second and more dangerous reason is the possibility of consuming adulterated honey or honey contaminated with heavy metal residues, as damaged kidneys are unable to filter these toxins, exposing them to further deterioration and stress.
Side Effects of Honey on Teeth
The sticky and dense structure of honey clings to tooth surfaces and the spaces between molars for long periods. This adhesion provides an ideal environment for oral bacteria, which feed on sugars and secrete strong acids that attack enamel and weaken tooth structure if not cleaned well.
Side Effects of Honey on the Face and Skin
Honey causes local allergy appearing as redness, itching, or slight swelling, especially for those who already suffer from pollen allergies.
Also, its heavy texture causes the trapping of excess oils and dead cells, leading to the appearance of pimples and acne for owners of oily and mixed skin.
Side Effects of Honey on Hair and Eyes
Using honey on hair without sufficient dilution or neglecting to wash it carefully leaves sticky residues that attract dust, making hair dull and tangled.
Placing honey on the eye causes severe irritation and burning, and unsterilized honey transfers bacteria that cause corneal ulcers and vision-threatening infections.
Side Effects of Honey on the Navel
Placing honey inside the navel cavity—which is a naturally warm and moist area—creates an ideal environment for the multiplication of bacteria and fungi, causing a skin infection, redness, and irritation in the surrounding tissues, accompanied by foul-smelling secretions.
Side Effects of Placing Honey on the Penis
This use leads to annoying harms, as the nature of honey causes severe irritation and redness in this sensitive skin. Also, not washing it immediately and correctly stimulates the growth of fungi and bacteria, raising the possibility of a skin or genital infection leading to itching and pain.
Side Effects of Different Types of Honey
Honey varieties in the markets vary based on the nectar source the bees feed on, and each type has its characteristics. Therefore, it is necessary to know that each variety has warnings and harms that appear upon misuse or choosing a non-pure product.
Side Effects of Sidr Honey
Its harms are exactly similar to the harms of natural honey. The problem lies only in the risk of overconsuming it without calculation, leading to the accumulation of sugars and calories, threatening weight gain and raising blood sugar levels.
Side Effects of Manuka Honey
Its potential side effects include the possibility of causing allergic reactions in some. Also, diabetics must be cautious of it because it raises sugar faster in the body.
Side Effects of Mad Honey
This honey contains a natural toxin that directly attacks the nervous system and heart. Consuming an extra teaspoon of it leads to immediate poisoning, with visual and auditory hallucinations requiring immediate entry into intensive care.
Side Effects of Royal Honey
Analysis has proven the presence of undeclared chemicals on the packaging. For this reason, this honey poses a fatal danger to heart and blood pressure patients and those taking medications regularly, as mixed honey causes a sharp drop in blood circulation or sudden heart attacks.
Side Effects of Black Forest Honey
Black Forest honey is extracted from insect secretions on trees and not from flower nectar. It is characterized by its dark color and high mineral content. Its harms focus on its high sugar and calorie content, making it unsuitable for consumption by diabetic and obese patients.
Side Effects of Glucose Honey
Glucose honey is a synthetic product resulting from commercial fraud and the recycling of starch to produce a thick sugary syrup. It completely lacks vitamins and causes a rapid rise in blood sugar immediately upon consumption, which increases the chances of developing morbid obesity and rapidly evolving insulin resistance.
Side Effects of Turkish Epimedium Honey
Health warnings around it stem from mixing honey with unstudied proportions of the Epimedium herb and other ingredients adulterated with chemicals. Overconsuming it leads to annoying side effects such as: accelerated heartbeat, persistent severe headache, dizziness, and sudden uncontrolled high blood pressure.
Side Effects of Clover Honey
It is characterized by its light sweet taste. Harms associated with it are limited to potential allergies, given that clover flower pollen is a common trigger for the respiratory system and skin. If a person suffers from pollen allergy, consuming this honey triggers itching and skin rash.
Side Effects of Capparis Honey (Shafallah)
Its primary problem lies in the limited scientific studies investigating its long-term properties. Potential effects of misuse or excess include mild digestive disturbances such as colic or gas, as well as the need for caution by pregnant women due to the lack of proven full safety for fetuses.
Side Effects of Ginseng Honey
This type is prepared by mixing natural honey with ginseng root powder to increase energy and activity. Its harms appear due to the dangerous drug interactions of ginseng, as it can react negatively with blood thinners and diabetes medications. Also, ginseng is a powerful stimulant that causes high blood pressure, acute insomnia, and nervous tension if consumed in large quantities or shortly before sleep.
Side Effects of Vega Honey
Exactly like royal honey, it falls under the official warnings issued by health regulatory authorities. This is because its harms are extremely dangerous due to some of its products containing adulterated materials to treat erectile dysfunction in random and unsafe doses, threatening a sharp drop in blood pressure, chronic headache, and vision problems. It is strictly prohibited for arterial and heart patients.
Side Effects of Sugarcane Honey (Molasses)
It is not real honey produced by bees, but rather a sugary product resulting from boiling and concentrating sugarcane juice. Its harms stem from being pure concentrate, and excess causes rapid obesity, sharply raises blood sugar, and leads to tooth decay.
Side Effects of Wild Honey
It is honey harvested from natural beehives in mountains or caves without human intervention. Despite its high quality, its harms are related to environmental pollution and variation in quality. In the wild, bees feed on toxic plants without supervision, and its primitive harvesting methods make it susceptible to contamination with dust, insect remains, or bacteria, causing food poisoning.
Side Effects of Flower Honey
The primary harm in this variety is the high probability of allergic reactions, given that it contains a concentrated and diverse mixture of different pollens, making it unsuitable for people with asthma or seasonal allergic rhinitis.
Side Effects of Fermented Honey
You can distinguish it by the appearance of foam on the surface and a pungent smell resembling alcohol. Consuming it causes acute food poisoning and severe intestinal disturbances including vomiting, nausea, colic, and severe diarrhea.
Side Effects of Commercial, Therapeutic, and Adulterated Honey
Not all containers in the markets carry the same therapeutic value. In many cases, honey turns from a medicinal substance into a source of health problems due to the way it is processed in factories or the manipulation of its ingredients. Therefore, pay attention to the following:
Side Effects of Therapeutic Honey
Therapeutic honey refers to rare types or those supported by antibacterial properties such as Manuka honey or pure Sidr honey, which are used for a specific medical purpose. The harms of this type lie in two main aspects:
- Misuse: Such as placing it on open wounds or severe burns.
- Relying on it as a substitute for medical treatment: Leading to a serious worsening of the health condition.
Side Effects of Commercial (Processed) Honey
Commercial honey is honey that is re-manufactured in factories to reach the consumer on shelves, but it carries many negatives, including:
- Sugar Additives: Some factories resort to mixing honey with high fructose corn syrup or glucose syrup to increase the product volume and lower its cost.
- Lower Nutritional Value: Commercial honey undergoes pasteurization and filtration processes, and this process destroys most vitamins and antioxidants, making it lack true benefits.
Side Effects of Adulterated Honey
Adulterated honey is classified as the most dangerous type of honey ever because the nature of the food is manipulated and completely deceives the consumer with materials that harm their body.
- Impact on Health: Accelerates the onset of insulin resistance, fatty liver, and morbid obesity, as well as exhausting the pancreas.
- Indicators that Reveal Adulteration: Such as honey dissolving very quickly when poured into a cup of water without stirring, or remaining completely liquid and not crystallizing when left in cold weather for long periods, or the ascent of a smell resembling caramel when heated.
How to Avoid the Side Effects of Honey?
To enjoy the sweet taste and therapeutic benefits of honey without worrying about side effects, you can follow these simple steps in your daily routine:
- Stick to safe daily quantities, which are equivalent to one to two tablespoons maximum for a healthy adult, and calculate them within the calories prescribed for your day.
- Be sure to acquire honey from known apiaries and stores with a good reputation, such as Al-Mathaq Al-Shafi store for honey and dates, which provides products free from commercial fraud, pesticide residues, or antibiotics.
- Stick to the strict medical rule that prohibits offering honey completely to children under one year of age, to protect them from the risk of severe poisoning.
- If you suffer from diabetes, deal with honey with extreme caution, measure glucose levels regularly, and be sure to deduct the amount of honey consumed from the carbohydrate portion available to you in the meal after consulting your treating physician.
- If you are using honey for the first time (consumption or topically on the skin), start with a very small amount and stop using it immediately if you notice any allergic symptoms such as itching, redness, or skin rash.
- When buying commercial honey from markets, check the data label carefully to ensure the product is "100% natural honey" and completely free from added sugars or high fructose corn syrup.
- Stay completely away from honey mixtures that promote miraculous benefits and are sold through unknown sellers, due to the high probability of their adulteration with unauthorized chemicals that pose a real danger to heart health and blood pressure.
Frequently Asked Questions
Is the honey available in Saudi markets considered safe for consumption?
Yes, the honey available in Saudi markets is considered safe for consumption provided it is purchased from reliable sources and stores subject to the control and supervision of the Saudi Food and Drug Authority (SFDA), which ensures the products are free from contaminants and commercial fraud before they are offered to consumers.
What is the reason for official warnings against royal honey products in Saudi Arabia?
Official warnings against royal honey are due to some unknown companies and entities adulterating it commercially by adding undeclared chemical medicinal substances (such as the active ingredient for sexual stimulants), which poses a danger to heart and blood pressure patients.
Does Sidr honey affect blood sugar levels?
Yes, Sidr honey affects blood sugar levels as it consists mainly of simple sugars (glucose and fructose). Therefore, overconsuming it leads to raising blood sugar just like any other type of honey.
How can one distinguish between natural and adulterated honey at home?
They can be distinguished by placing a drop of honey in a cup of water. Pure natural honey settles at the bottom as a cohesive mass and does not dissolve except by stirring, while honey adulterated with sugar syrup dissolves and spreads in the water quickly as soon as it falls.
Can consuming honey lead to food poisoning?
Yes, honey can lead to food poisoning in two cases: first, when given to infants under one year of age, and second, when consuming fermented honey that has been damaged and exposed to moisture during storage.
Does daily consumption of honey on an empty stomach cause damage to the liver?
Natural honey does not cause any damage to a healthy liver when consumed in moderation (one small teaspoon daily). However, extreme overconsumption of large quantities on an empty stomach provides the liver with high doses of fructose, contributing to fat accumulation.
When is honey beneficial for health and when does it become harmful?
Honey is beneficial when it is natural and pure and consumed in moderation as a healthy and nutritious alternative to refined sugars. It becomes harmful when consumed in excessive amounts, boiled and exposed to high heat, or adulterated with chemical sugar solutions that harm the body.
