What is lactose and dairy ?

Lactose is a sugar found in milk and other dairy products. It is broken down into glucose and galactose, which are then absorbed into the bloodstream. People with lactose intolerance have difficulty digesting lactose, which can lead to gas, bloating, diarrhea, and other symptoms.

Lactase is an enzyme that breaks down lactose into glucose and galactose. People with lactase deficiency do not produce enough of this enzyme, which can cause problems digesting lactose-containing foods.

Dairy refers to milk and milk-based products that come from cows, goats, sheep, or other mammals. These products include milk, cheese, butter, yogurt, ice cream, and more. Dairy is a common source of calcium, protein, and other nutrients in many people’s diets.

Pros and cons of lactose and dairy-free diet

Pros of a lactose-free diet:

  • Helps alleviate symptoms of lactose intolerance such as bloating, gas, and diarrhea
  • Can still include dairy products that have been treated to remove lactose, providing some nutritional benefits of dairy
  • May be easier to follow than a completely dairy-free diet

Cons of a lactose-free diet:

  • May still contain some lactose, which can trigger symptoms in people with severe lactose intolerance
  • May not address other issues related to consuming dairy, such as milk allergy or sensitivity to other components of milk
  • May limit the intake of some beneficial nutrients found in dairy, such as calcium and vitamin D

Pros of a dairy-free diet:

  • Can be beneficial for those with milk allergies or sensitivities
  • Can help reduce inflammation and symptoms related to autoimmune conditions
  • May encourage the consumption of other nutrient-dense foods such as fruits, vegetables, and plant-based proteins

Cons of a dairy-free diet:

  • May require more careful planning to ensure an adequate intake of nutrients found in dairy such as calcium, vitamin D, and protein
  • May be more expensive or difficult to find alternative sources of certain dairy products, such as cheese or yogurt
  • May not be necessary or beneficial for everyone, as dairy can be a healthy part of a balanced diet for many people

Examples of foods that you can eat on a lactose or dairy-free diet

Fruits and vegetables: All fruits and vegetables are naturally lactose-free and Dairy free (with the exception of those that may be processed with milk or cream such as some frozen yogurts).

Meat and poultry: Any type of fresh meat or poultry is naturally Dairy free


Lactose-free recipes typically use alternative ingredients such as soy milk, almond milk, or rice milk. Dairy-free recipes may use these same alternative ingredients, but they may also include other non-dairy items such as coconut milk or hemp milk.

Key differences between lactose and dairy-free

  1. Lactose-free means that the product has had lactose, a type of sugar found in milk, removed. Lactose is the main carbohydrate in dairy products, and people who are lactose intolerant lack the enzyme lactase, which is needed to break down lactose. Lactose-free products, therefore, are still dairy-based, but they have had the lactose removed.
  2. Dairy-free, on the other hand, means that the product does not contain any dairy ingredients whatsoever. This includes milk, cream, cheese, butter, and any other product that comes from an animal’s milk.
  3. Lactose-free products are suitable for people who are lactose intolerant and cannot digest lactose, but they are not suitable for people who are allergic to milk or who have a dairy allergy. Dairy-free products, on the other hand, are suitable for people with a milk allergy or who are vegan and do not consume animal products.
  4. Lactose-free products may still contain milk proteins, which can cause an allergic reaction in people with a milk allergy. Dairy-free products are free from milk proteins as well as lactose, making them safe for people with a milk allergy or who are lactose intolerant.
Differences between Lactose and Dairy-Free


Lactose-free products contain small amounts of lactose, while dairy-free products do not contain any animal milk or its derivatives. Both can provide a great alternative for those who want to reduce their intake of dairy but still enjoy delicious foods. Whether you choose lactose-free or dairy-free, it is important to read labels carefully so that you know exactly what is in each product and how it fits into your diet plan.
