A lactose free diet is one that avoids lactose, a type of sugar found in milk and dairy products. This diet is often followed by people who are lactose intolerant, meaning their bodies have trouble digesting lactose.
If dairy leaves you feeling bloated, gassy, or uncomfortable, switching to a lactose free diet can make a big difference in how you feel day to day.

What Is Lactose?
Lactose is a natural sugar found in milk from cows, goats, and sheep. It is also in many dairy products like cheese, yogurt, and ice cream. To digest lactose, your body uses an enzyme called lactase. If you do not make enough lactase, lactose stays in your gut and causes symptoms.
Common signs of lactose intolerance include:
- Bloating
- Stomach cramps
- Gas
- Diarrhea
- Nausea
These symptoms usually appear 30 minutes to 2 hours after eating or drinking dairy.
What Is a Lactose Free Diet?
A lactose free diet means avoiding all foods that contain lactose. Some people go completely dairy free, while others can handle small amounts depending on their sensitivity.
This diet is not the same as a dairy free or vegan diet. You can still eat dairy that has no lactose or has been treated to remove it.
Foods to Avoid on a Lactose Free Diet
If you are starting this diet, here are some foods that usually contain lactose:
- Milk (whole, low-fat, skim, and cream)
- Cheese (especially soft cheeses like cream cheese, ricotta, and cottage cheese)
- Butter and margarine with milk solids
- Yogurt
- Ice cream
- Puddings and custards
- Baked goods made with milk
- Processed foods with milk powder or whey
Be sure to read ingredient labels. Lactose often hides under names like:
- Whey
- Curds
- Milk solids
- Casein
- Dry milk powder
Lactose Free Alternatives
The good news is that many lactose free options are easy to find today. Some popular substitutes include:
- Lactose free milk made from real dairy but treated to remove lactose
- Plant-based milks like almond milk, oat milk, soy milk, and coconut milk
- Lactose free yogurt made from coconut, soy, or almond bases
- Vegan cheese made from nuts, soy, or starches
- Non-dairy ice cream made from coconut, almond, or oat milk
- Butter alternatives like olive oil spread or dairy free margarine
You can also buy lactase enzyme supplements to help digest small amounts of dairy when needed.
Nutrients to Watch
When you remove dairy from your diet, it is important to make sure you are still getting key nutrients, especially:
- Calcium: Important for bone health. Found in leafy greens, almonds, tofu, and fortified plant milks
- Vitamin D: Helps your body absorb calcium. You can get it from sun exposure or fortified foods
- Protein: Most people get enough from other sources like meat, beans, lentils, nuts, and seeds
Consider taking a supplement if you are not getting enough from food.

Who Should Follow a Lactose Free Diet?
This diet is mainly for people with:

- Digestive conditions like IBS or IBD where dairy makes symptoms worse
Always talk to a doctor or dietitian if you are not sure whether dairy is the issue.
Final Thoughts
A lactose free diet can be simple and satisfying with a little planning. Thanks to all the modern dairy alternatives, you can still enjoy many of your favorite foods without the discomfort.
Start by reading labels, swapping out high-lactose foods, and keeping track of how you feel. Whether you go fully lactose free or just reduce it, your gut will thank you.
