Living Well with Lactose Intolerance: Ensuring Adequate Vitamin D Intake



Lactose intolerance can feel like a puzzle, especially when it comes to enjoying the benefits of dairy - the primary source of calcium and vitamin D for many. This condition arises from a deficiency in the lactase enzyme, making it tricky to digest lactose, the sugar in milk. But fear not! Navigating lactose intolerance doesn’t mean you have to sacrifice your bone health or miss out on essential nutrients. 


The Importance of Vitamin D 

Vitamin D plays a crucial role in your body, primarily helping you absorb and utilise calcium, which is vital for strong bones and teeth. So, let’s explore how you can keep your vitamin D levels in check, even if dairy isn’t on your menu. 


Primary Sources of Vitamin D 

While dairy products are a familiar source of vitamin D, there’s a whole world of alternatives waiting to be discovered. Your body can actually produce vitamin D when your skin soaks up sunlight, which is pretty neat! 


Sunlight Exposure 

From late March through September, many folks in the Northern Hemisphere can bask in the sun and get their daily dose of vitamin D just by stepping outside. However, keep in mind that time of day, skin tone, and even sunscreen can affect how much vitamin D you produce. When the colder months roll in, sunlight becomes less reliable, so it’s time to turn to dietary sources and vitamin D supplements


Dietary Sources (Naturally Occurring) 

While options are limited, there are still some delicious foods that can help you meet your vitamin D needs: 
  • Oily Fish: Think salmon, sardines, trout, herring and mackerel. A 3-ounce serving of canned salmon or sardines (bones included for extra calcium) can give you a solid boost of both nutrients. 
  • Eggs: The yolk is where the magic happens! One large egg contains a modest amount of vitamin D. 
  • Red Meat and Liver: These options provide smaller amounts of vitamin D, but every bit counts! 


Fortified Foods and Products 

To help you stay on track, many foods are fortified with vitamin D. Always check the labels to see how much you’re getting: 
  • Plant-Based Milks: Soy, almond, rice, and oat milks are often fortified to match the levels found in cow's milk. 
  • Fortified Juices and Cereals: Some brands of orange juice and breakfast cereals come with added vitamin D - talk about a breakfast win! 
  • Mushrooms: Certain commercially available mushrooms get a vitamin D boost by being exposed to UV light during growth. 


Dietary Strategies for Managing Lactose Intolerance 

You don’t have to wave goodbye to dairy entirely! Many people with lactose intolerance can enjoy small amounts of lactose, especially when paired with other foods. Here are some friendly strategies: 
  • Lactose-Free Products: These delightful options have the lactase enzyme added in, making them easier on your tummy. 
  • Hard Cheeses and Yogurt: Hard cheeses (like Parmesan and Swiss) and yogurts with “active live cultures” are usually lower in lactose and often better tolerated. 
  • Lactase Supplements: You can find over-the-counter lactase enzyme pills or drops that can help you enjoy dairy with greater ease. 


Supplements and Medical Advice 

Even with careful planning, some folks still fall short on vitamin D. If you have concerns about your intake, it’s wise to chat with a healthcare provider. They can help you determine if a calcium or vitamin D supplement is right for you, ensuring you meet your nutritional needs. 

In summary, embracing a lactose-free lifestyle can be both delicious and nutritious. With a little creativity and some thoughtful planning, you can thrive while keeping your bones and overall health in check.
