What is Malt?
Malt is a cereal grain, most commonly barley, that has undergone a process of malting. This involves soaking the grain in water until it begins to sprout, after which it is dried with hot air to halt the germination process. This process releases the grain's enzymes, which convert starches into fermentable sugars, most notably maltose. Malt is a versatile ingredient used in a wide variety of products, including beer, whiskey, malted milkshakes, breakfast cereals, and baked goods.
While malt can offer some nutritional benefits, such as B vitamins, minerals, and amino acids, its overall health impact is highly dependent on the type of product and the amount consumed. Non-alcoholic malt beverages, malternatives, and malted shakes, for instance, often contain high levels of added sugars and calories.
Potential Health Side Effects
Weight Gain and Obesity
One of the most common side effects of consuming too much malt, especially in sweetened beverages and treats, is weight gain. Malt is primarily a carbohydrate source and, as an added sugar, it contains calories without significant nutritional value. When the body consumes more calories than it burns, the excess energy is stored as fat. Many popular malt-based products, such as milkshakes and sweetened non-alcoholic drinks, are high in calories and sugar, making them a significant contributor to weight gain if consumed frequently.
Blood Sugar Spikes and Diabetes Risk
The sugar in malt, primarily maltose, is broken down into glucose in the body, which can lead to a sharp increase in blood sugar levels. For those with diabetes or insulin resistance, this can pose a serious health risk. While some studies on whole barley suggest potential benefits for blood glucose control, the evidence for malt—which has a higher sugar content due to the malting process—is less conclusive. Excessive, long-term consumption of high-sugar malt products can contribute to the development of chronic conditions like type 2 diabetes. For diabetics, natural sweeteners like stevia are a far safer alternative.
Gluten Sensitivity and Allergies
Since most commercial malt is made from barley, it is not safe for individuals with celiac disease or gluten sensitivity. For these people, consuming any product containing malt can trigger an immune response, leading to a range of symptoms including digestive distress, fatigue, and other systemic issues. Always check product labels, as malt can be listed as 'malted barley' or 'malt extract'. While some gluten-free malt products are becoming available, they are still not the standard.
Digestive Issues
Certain malt extracts, particularly those marketed as bulk-forming laxatives, can cause significant digestive side effects. These include gas (flatulence), excessive bowel activity, and diarrhea. In cases of misuse or overdose, more severe issues like fecal impaction or bowel obstruction can occur, especially without adequate fluid intake. The fiber content in some malt products, while beneficial in moderation, can cause discomfort if consumed in large quantities.
Other Potential Side Effects
- Dental Issues: The high sugar content in many malt drinks can contribute to tooth decay and other dental problems over time.
- Dehydration (Alcoholic Malt): Alcoholic malt beverages, like beer and malt liquor, are diuretics and can lead to dehydration if consumed in excess.
- Heartburn: Some individuals may experience acid reflux or chest pain after consuming malt, potentially linked to a hiatal hernia or GERD.
- Excessive Belching: Carbonated malt beverages can lead to increased gas and belching.
Comparison of Malt Beverages and Associated Risks
To better understand the risks, it's helpful to compare the different forms of malt products available.
| Feature | Non-Alcoholic Malt Drink | Malted Milkshake | Malt Liquor | Malt Extract (Syrup) |
|---|---|---|---|---|
| Sugar Content | High (added sugars) | Very High (added sugars and ice cream) | Moderate to High (fermented) | High (concentrated added sugar) |
| Calorie Count | Moderate to High | High to Very High | High (due to alcohol) | Moderate (used in cooking) |
| Gluten Content | Typically contains gluten | Typically contains gluten | Contains gluten | Contains gluten |
| Main Health Risk | Obesity, diabetes risk | Weight gain, high blood sugar | Alcohol-related issues, high sugar | Blood sugar spikes, obesity |
| Consumption Context | Often marketed as a healthy energy drink | Dessert or treat item | Alcoholic beverage | Sweetener in recipes or supplement |
Conclusion
While malt in its whole-grain form can provide nutrients, the side effects of drinking malt are significant, especially when consumed in processed forms with high added sugars. Excessive intake can lead to weight gain, obesity, and an increased risk of chronic conditions like type 2 diabetes due to rapid blood sugar spikes. Individuals with gluten sensitivity or celiac disease must avoid malt products containing barley. Different malt-based beverages carry different risks, from the high sugar of non-alcoholic options to the high alcohol content of malt liquor. The key takeaway for all consumers is moderation, especially for those with underlying health concerns. Always check the ingredients list and consult a healthcare provider if you have specific dietary restrictions or health issues.

Frequently Asked Questions
1. Is malt good for you? Malt contains some nutrients like B vitamins, but its health effects depend heavily on the type of product. Many malt drinks contain high added sugars, which can be harmful in excess.
2. Can malt make you gain weight? Yes, excessive consumption of malt-based products, particularly those with added sugars and high calories like milkshakes and non-alcoholic malt beverages, can lead to weight gain and obesity.
3. Is malt bad for people with diabetes? Maltose, the sugar in malt, breaks down into glucose and can cause blood sugar spikes. People with diabetes should be very cautious and consider alternatives to control their blood sugar levels.
4. Does malt contain gluten? Most malt is made from barley and is not gluten-free. Individuals with celiac disease or gluten sensitivity must avoid it unless explicitly labeled as gluten-free.
5. Can malt cause digestive problems? Yes, certain malt extracts used as laxatives can cause gas, bloating, and diarrhea. High consumption can also lead to digestive discomfort.
6. Is non-alcoholic malt healthy? Not necessarily. While they lack alcohol, many non-alcoholic malt beverages are high in added sugars and calories, which can contribute to weight gain and blood sugar issues.
7. Who should avoid malt? People with celiac disease, gluten sensitivity, diabetes, or a history of obesity should limit or avoid malt-based products due to the associated risks.
8. What are some healthier alternatives to malt? For sweetness, consider natural sweeteners like stevia. For a nutritional boost, choose whole grains or fruits and vegetables, which provide nutrients without excessive added sugars.
