Having a food intolerance is not fun. It can cause abdominal pain, discomfort, and nausea. It also causes embarrassing symptoms like flatulence and diarrhea. Other symptoms linked to food intolerances include muscle or joint pain, headaches, exhaustion, and even skin symptoms like rashes and eczema.
Dairy is just one of those foods that many people seem to be intolerant of. Let’s talk about the main components of milk that people react to: lactose, casein, and whey.
Milk sugar (lactose) intolerance
It’s estimated that up to 75% of adults are lactose intolerant. Lactose is the carbohydrate “milk sugar” naturally found in most dairy products. Lactose intolerance is so common you can buy lactose-free milk in your regular grocery store. Lactose-free products are treated with the enzyme “lactase” that breaks the lactose down before you ingest it. It’s this lactase enzyme that is lacking in most people who are lactose intolerant.
The lactase enzyme is naturally released from your intestine as one of your digestive enzymes. It breaks down the lactose sugar in the gut. When someone doesn't have enough lactase, the lactose doesn't get broken down the way it should. Undigested lactose ends up being food for the resident gut microbes. As they ferment the lactose, they create gases that cause bloating, flatulence, pain, and sometimes diarrhea.
Lactose is in dairy but is in lower amounts in fermented dairy (e.g. cheese & yogurt) and butter. Steering clear of lactose isn't that easy as it is added to other foods like baked goods, soups, and sauces. And if you're taking any medications or supplements, check to see if it's in there too, as lactose is a common ingredient in them.
If you have symptoms of lactose intolerance, keep an eye on food, medication, and supplement labels.
Milk protein (casein & whey) allergy
Milk is a known, and common, food allergen. In Canada, it is considered a “priority allergen” and must be declared on food labels.
So, what are the allergens in milk? You've heard of "curds and whey?" Well, these are the two main proteins in milk. The solid bits are the curds (made of casein), and the liquid is the dissolved whey.
Unlike lactose intolerance, casein and whey can cause an actual immune response. It’s an allergy. And this immune response can cause inflammation. In fact, we don’t know how many people have these milk allergies, but most estimates put it far below that of lactose intolerance.
Like lactose, these allergenic milk proteins can be found in other products too. They're not just in dairy but are often in protein powders as well (Have you heard of "whey" protein powders?).
Some of the symptoms of milk protein allergy differ from that of lactose intolerance; things like nasal congestion and mucus (phlegm) are more common here. And casein seems to be linked with belly fat.
Interestingly, people who have gluten intolerance are often allergic to milk proteins like whey and casein as well. These can go hand-in-hand.
Like lactose intolerance, if you're allergic to casein and whey keep an eye on labels so you can avoid these.
If you get gassy, bloated, or diarrhea after eating dairy, you may have a lactose intolerance. If you often get a stuffy nose and mucus, then you may be allergic to casein and/or whey.
While dairy may be an entire food group, it is not an essential nutrient. All the nutrients in dairy are available in other foods. If you experience these symptoms, you can try removing dairy from your diet. You may find improved digestion and fewer gut issues. Or you may find improved nasal congestion, or even less belly fat.
If you decide to (or have already) removed dairy from your diet, let me know your experience in the comments below.

You are positive that you're not eating more food or “junkier” food but you're still gaining weight.
Is this possible?
Yes! You are NOT crazy!
And here's why.
We both know that the whole “calories in, calories out” argument is an overly simplistic view of weight.
There's definitely more to the story than just what you're eating, right?
A lot of this comes right down to your metabolic rate which is affected by things like your activity level, history of dieting, body composition, and even what you eat.
But, let's go beyond the “eat less and exercise more” advice and dive into some of the less obvious underlying reasons why you may be gaining weight even though you're eating the same.
Funny things happen the older we get. People commonly experience lower energy levels, more digestive discomfort, weight gain, as well as aches and pains.
Aging can result in hormonal changes for both men and women. And these can contribute to loss of some lean muscle mass, as well as increases and changes in fat storage on our bodies.
The good thing is that, this is very common and not your fault one bit.
Your thyroid is the master controller of your metabolism and can be a massive contributor to your weight gain. There are several things that can affect it and throw it off course.
When your thyroid gets off course and produces fewer hormones your metabolism slows down. And when your metabolism slows down you can gain weight. Even though you're eating the same way you always have.
Pro Tip: Talk with your doctor about having your hormones tested. Oh, and try the thyroid-friendly recipe that I created for you at the end of this post.
There is plenty of research that shows the influence that sleep has on your metabolic rate.
And as we age it can become harder and harder to get a good night's sleep.
The general consensus is to get 7-9 hours of sleep every night to help avoid weight gain.
It's true! Lack of sleep is linked with weight gain.
Who ever thought you can sleep off your weight?
Pro Tip: Try to get at least 7 hours of sleep every night. The first place to start is by implementing a calming before bedtime routine.
It seems to be everywhere! So many things that can cause stress responses in your body.
And you know that stress hormones are not going to help you sustain healthy habits or maintain a healthy weight, right?
While you can't necessarily change your stressors you can try to adjust your stress response to them.
Pro Tip: Try meditation or yoga. Or even mindful eating. What about those new adult colouring books that are all the rage now?
There are lots of factors that can affect your weight, even if you're eating the same way you always have. Aging, hormones, stress, and sleep are all interconnected to each other and can all contribute to weight gain, even if you're eating the same way you always have.
