The Basics of Lactose Intolerance
Lactose intolerance is a common digestive issue caused by the body's inability to fully digest lactose, the main sugar in milk and dairy products. This happens due to a deficiency of the enzyme lactase, which is produced in the small intestine. Without enough lactase, undigested lactose moves to the large intestine, where bacteria ferment it, leading to uncomfortable symptoms. These symptoms often include bloating, gas, stomach cramps, and diarrhea, typically appearing within a few hours of consuming dairy. It is important to note that lactose intolerance is not an allergy and is not life-threatening, but it can significantly impact comfort and quality of life.
Why Ingredient Formulation Matters
Before determining if custard is worse than ice cream for lactose intolerance, one must look at the fundamental ingredients. Both are dairy-based desserts, containing a mix of milk, cream, and sugar. The primary distinction lies in the addition of egg yolks to custard, which gives it a denser, richer texture. While this affects the fat and protein content, it does not necessarily change the overall lactose burden in a way that would make one definitively worse than the other. The lactose content depends almost entirely on the type and quantity of dairy ingredients used, rather than the presence of eggs. For example, a frozen custard made with a higher percentage of heavy cream could contain more lactose than a lighter ice cream with a higher milk content.
Custard vs. Ice Cream: A Detailed Comparison
| Feature | Standard Custard | Standard Ice Cream |
|---|---|---|
| Primary Dairy | Milk, cream, and egg yolks | Milk and cream |
| Defining Ingredient | Egg yolks (at least 1.4% in the U.S.) | No egg yolks required |
| Texture | Dense and creamy due to egg solids | Lighter and airier due to higher air content |
| Potential Lactose | Contains significant lactose due to milk and cream | Contains significant lactose due to milk and cream |
| Prevalence of Alternatives | Lactose-free versions less common commercially | Many readily available lactose-free versions |
Unpacking the Lactose Content
Research has shown that ready-made custard can contain a significant amount of lactose, with some products ranging from 4.6 to 5.4g per 100g. Similarly, whole cow's milk contains 4 to 5g of lactose per 100g, so the concentrations are quite comparable. The ultimate lactose load you experience depends on the specific brand's recipe. While custard and ice cream can both be problematic, it is the total amount of lactose consumed in a single sitting that triggers symptoms for most people with intolerance. Therefore, moderation and portion control are crucial, regardless of the dessert type.
Managing Your Symptoms and Finding Alternatives
For those with lactose intolerance, avoiding dairy entirely is not always necessary. Many individuals can tolerate a certain amount of lactose, particularly when consumed with other foods.
Strategies for Enjoying Desserts
- Portion Control: Consuming a smaller serving may prevent symptoms. For example, some people can handle up to 12-15 grams of lactose at once.
- Enzyme Supplements: Over-the-counter lactase enzyme supplements can be taken just before eating dairy to help the body break down lactose.
- Food Pairing: Eating dairy alongside other foods can sometimes slow down digestion, making it easier for the body to process the lactose.
Lactose-Free Alternatives
Fortunately, a wide variety of dairy-free and lactose-free options are now available for both ice cream and custard, making it easier to enjoy these treats without discomfort.
- Dairy-Free Ice Cream: Available in numerous brands and flavors, often made with bases like almond milk, coconut milk, or oat milk.
- Lactose-Free Milk: Many supermarkets offer lactose-free cow's milk, which can be used to make homemade lactose-free custard.
- Plant-Based Custard: Homemade custard can be easily prepared using plant-based milks and egg substitutes or eggs, as evidenced by many recipes.

Conclusion: The Verdict on Custard vs. Ice Cream
In the debate over whether custard is worse than ice cream for lactose intolerance, the answer is that neither is inherently worse. The level of discomfort is directly tied to the total lactose content of the specific product and the individual's unique tolerance threshold. Since both are made primarily from milk and cream, both pose a risk for symptoms. The presence of egg yolks in custard does not significantly alter the lactose equation. Instead of focusing on the dessert category, individuals should investigate the specific ingredients and portion size. With the growing availability of lactose-free alternatives, those with sensitivities have more options than ever to enjoy a creamy, delicious treat without the unwanted side effects.
