Is there a lot of sugar in a milkshake?

3 min read

According to a 2018 survey by Action on Sugar, some fast-food milkshakes can contain up to 39 teaspoons of sugar. A typical milkshake is loaded with sweeteners from multiple sources, and yes, there is a lot of sugar in a milkshake, especially those from fast-food chains.

Quick Summary

Milkshakes, particularly those from fast-food restaurants, are notoriously high in sugar due to ice cream, syrups, and toppings. While milk contains natural lactose, the vast majority comes from added sugars. Healthier versions can be made at home using low-sugar alternatives like Greek yogurt or fresh fruit instead of processed ingredients.

Key Points

  • High Sugar Content: A single fast-food milkshake can contain more sugar than the recommended daily limit for an adult.

  • Multiple Sugar Sources: The high sugar load comes from a combination of ice cream, flavored syrups, sweet toppings, and natural milk lactose.

  • Healthier Alternatives Exist: Homemade milkshakes can be made with significantly less sugar by using frozen fruit, Greek yogurt, and plant-based milks.

  • Health Risks: Excessive sugar consumption from milkshakes contributes to weight gain, blood sugar spikes, and an increased risk of chronic diseases.

  • Ingredient Control is Key: Swapping high-sugar ingredients for natural, whole foods is the most effective way to reduce the sugar content of a milkshake.

The Shocking Reality of Milkshake Sugar Content

For many, a thick, creamy milkshake is a beloved indulgence. However, a single, large fast-food milkshake can contain more sugar than the recommended daily allowance, sometimes exceeding it by double or even triple. This excessive sugar load comes not from a single ingredient but from a combination of sweetened components.

Where the Sugar in a Milkshake Comes From

  • Ice Cream: This is the foundation of most milkshakes and a major contributor of sugar. Ice cream is made with milk, sugar, and cream, meaning it brings a significant amount of both natural and added sugars to the blend.
  • Syrups: Flavorings like chocolate, caramel, and strawberry syrups are pure sugar, often corn syrup, which can dramatically increase the overall sugar count.
  • Toppings and Mix-Ins: Ingredients like whipped cream, cookie pieces, candy, and sprinkles are all additional sources of sugar that can easily turn a milkshake into a sugar bomb.
  • Milk (Lactose): Even the milk used has natural sugars (lactose), though this contributes a much smaller amount compared to the added sweeteners.

The Impact of High-Sugar Milkshakes

Consuming a high-sugar milkshake can lead to several health issues beyond just a momentary sugar rush. The rapid spike in blood sugar can cause an energy crash and, over time, can contribute to significant weight gain due to high calorie counts. Furthermore, a diet high in added sugars is a risk factor for conditions like type 2 diabetes and heart disease. Fast-food shakes in particular are known to have "grotesque levels of sugar" that far exceed daily recommendations.

Healthier Ways to Enjoy a Milkshake

Fortunately, it's possible to create a delicious and satisfying milkshake with a much lower sugar content. The key is to control the ingredients and replace processed, high-sugar components with natural alternatives.

  • Use Natural Sweeteners: Instead of refined sugar, try natural sweeteners with a lower glycemic index, like a small amount of dates, a dash of cinnamon, or stevia.
  • Go Frozen: Use frozen fruit, such as bananas or berries, to provide natural sweetness and a thick texture without added sugar.
  • Swap Dairy: Consider swapping ice cream for low-fat Greek yogurt, which adds protein and creaminess with much less sugar. For the liquid, use unsweetened plant-based milk or low-fat dairy.

Comparison Table: Fast-Food Milkshake vs. Healthy Homemade Shake

Feature Fast-Food Shake (e.g., Large Chocolate) Homemade Healthy Shake (e.g., Berry Yogurt)
Primary Sweeteners Ice cream, syrups, added sugar Frozen berries, small amount of natural sweetener (e.g., stevia)
Total Sugar (approx.) Often 90-110+ grams Can be less than 20 grams, depending on ingredients
Main Ingredients Milk, ice cream, artificial flavorings, toppings Unsweetened milk/plant milk, Greek yogurt, frozen fruit
Added Protein Typically low or none Higher, especially with Greek yogurt or protein powder
Fiber Content Low to none Higher, from whole fruits and optional additions like chia seeds
Nutrient Density Low, often empty calories High, with more vitamins and minerals from fruit

The Bottom Line

While a fast-food milkshake is a potent source of sugar and empty calories, a homemade version can be a much healthier treat. By being mindful of ingredients, you can significantly reduce the sugar load and turn it into a more nutritious option. It’s a classic case of what you put in is what you get out, and with milkshakes, a little ingredient swapping goes a long way towards better health. If you are interested in making a healthier, lower-sugar milkshake, you can find simple recipes online that use alternatives like frozen bananas, Greek yogurt, and a touch of cinnamon.

Conclusion

In summary, the sugar content of a milkshake can be incredibly high, particularly in versions purchased from fast-food chains that rely on ice cream, sugary syrups, and sweet toppings. These commercial options can contain several days' worth of recommended sugar in a single serving. However, by making a shake at home and using whole, nutrient-dense ingredients like frozen fruit, Greek yogurt, and unsweetened milk, it is possible to create a delicious, creamy beverage that is far healthier and contains only a fraction of the sugar. This careful selection of ingredients can transform a once-unhealthy dessert into a more balanced and beneficial treat.

Frequently Asked Questions

The primary sources of sugar in a milkshake are the ice cream and any added flavorings, like chocolate or caramel syrup. The milk itself also contains some natural sugar (lactose), but the added sugars are the largest contributor.

The amount varies by size and flavor, but many large fast-food milkshakes can contain anywhere from 60 to over 100 grams of sugar. Some extreme examples have been found to contain up to 39 teaspoons of sugar.

Yes, you can make a low-sugar milkshake by replacing ice cream with ingredients like low-fat Greek yogurt and frozen fruit (like berries). Using unsweetened milk and natural sweeteners such as stevia can also help.

No, not all the sugar is inherently bad. Milk contains natural sugar in the form of lactose. However, the vast majority of the sugar in commercial milkshakes is added sugar from syrups and ice cream, which is detrimental in high quantities.

Use frozen fruit (especially lower-sugar berries) for sweetness, swap ice cream for Greek yogurt, use unsweetened milk, and choose toppings like chopped nuts or seeds over whipped cream and sprinkles.

Yes, due to their high content of added sugars from ice cream and syrups, milkshakes can cause significant and rapid spikes in blood sugar levels.

Yes, 'freakshakes,' which often include excessive toppings like candy, cookies, and whipped cream, contain even more sugar than a standard milkshake and can have extremely high calorie and sugar counts.
