Consider <strong>casein<\/strong> and <strong>whey proteins<\/strong>. Your immune system doesn't necessarily go into action like an allergy, but your digestion and metabolism can get pretty confused. So it is not an allergy, but rather a <strong>hypersensitivity reaction<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms that may accompany it<\/h2>\n\n\n\n<p>Symptoms are often more vague than in allergy. Common symptoms are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bloated belly<\/strong>: as if you were suddenly five months pregnant<\/li>\n\n\n\n<li><strong>Abdominal pain or cramps<\/strong>: sometimes immediately, sometimes not until hours later<\/li>\n\n\n\n<li><strong>Alternating stools<\/strong>: from constipation to diarrhea<\/li>\n\n\n\n<li><strong>Nausea<\/strong>: especially after eating dairy products<\/li>\n\n\n\n<li><strong>Fatigue<\/strong>: as if your battery is always half empty<\/li>\n\n\n\n<li><strong>Concentration problems<\/strong>: your head is full of cotton wool<\/li>\n\n\n\n<li><strong>Skin Problems<\/strong>: eczema, pimples or red spots<\/li>\n\n\n\n<li><strong>Headache or migraine<\/strong>: unexplained seizures after dairy<\/li>\n<\/ul>\n\n\n\n<p>Not everyone gets the same symptoms, and the severity varies from person to person. That is precisely what makes it so difficult to recognize.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"637\" src=\"https:\/\/noomooo.com\/wp-content\/uploads\/2025\/08\/4.jpg\" alt=\"\" class=\"wp-image-112\" title=\"\" srcset=\"https:\/\/noomooo.com\/wp-content\/uploads\/2025\/08\/4.jpg 900w, https:\/\/noomooo.com\/wp-content\/uploads\/2025\/08\/4-300x212.jpg 300w, https:\/\/noomooo.com\/wp-content\/uploads\/2025\/08\/4-768x544.jpg 768w, https:\/\/noomooo.com\/wp-content\/uploads\/2025\/08\/4-18x12.jpg 18w, https:\/\/noomooo.com\/wp-content\/uploads\/2025\/08\/4-750x531.jpg 750w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How is it different from cow's milk allergy?<\/h2>\n\n\n\n<p>Cow milk allergy and cow milk intolerance are often confused, but they are really different.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cow's milk allergy<\/h3>\n\n\n\n<p>A <strong>cow's milk allergy<\/strong> is a reaction from you <strong>immune system<\/strong>. Your body sees the proteins in milk as a threat and makes antibodies. This can cause severe reactions such as <strong>hives<\/strong>, <strong>tightness<\/strong> or even a <strong>anaphylactic shock<\/strong>. Cow's milk allergy occurs mostly in infants and young children, and is usually diagnosed through an allergy test.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cow's milk intolerance<\/h3>\n\n\n\n<p>At <strong>cow's milk intolerance<\/strong> there is no immediate immune response. The symptoms are different and more <strong>delayed<\/strong> and often do not arrive until hours or even a day later. As a result, it is often overlooked.<\/p>\n\n\n\n<p><strong>Want to know more about allergies? Read the blog: <a href=\"https:\/\/noomooo.com\/en\/difference-cows-milk-allergy-cows-milk-intolerance\/\">What is the difference between cow's milk allergy and intolerance?<\/a><\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What about lactose intolerance?<\/h2>\n\n\n\n<p><strong>Lactose intolerance<\/strong> deals with a deficiency of the enzyme <strong>lactase<\/strong>, making your body <strong>milk sugar (lactose)<\/strong> cannot digest properly. This can lead to <strong>flatulence<\/strong>, <strong>cramps<\/strong> and <strong>diarrhea<\/strong>.<\/p>\n\n\n\n<p>At <strong>cow's milk intolerance<\/strong> is the problem mainly in the <strong>proteins<\/strong>, not in the sugars. You can eat lactose-free and still have symptoms if you do ingest milk protein.<\/p>\n\n\n\n<p><strong>Curious about lactose?

You can often find out by temporarily (say, 4 weeks) <strong>eat cow's milk free<\/strong> and pay close attention to your symptoms. Do you feel better without cow's milk? Then chances are you are sensitive to it.<\/p>\n\n\n\n<p>It helps to create a <strong>food diary<\/strong> keep track and note when you have symptoms, what you ate and how you felt. In this way, you will slowly but surely gain insight into your own pattern.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What can you do for cow's milk intolerance?<\/h2>\n\n\n\n<p>The only real solution at <strong>cow's milk intolerance<\/strong> is: <strong>avoid cow's milk<\/strong>. Fortunately, there are more and more tasty <strong>plant-based alternatives<\/strong>. Consider <strong>oat milk<\/strong>, <strong>almond yogurt<\/strong>, <strong>vegan butter<\/strong>, <strong>vegetable cheese<\/strong>... The supermarket is well stocked here these days (thankfully).<\/p>\n\n\n\n<p>Note <strong>hidden dairy<\/strong>. Cow's milk is often hidden in products where you wouldn't expect it, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stock cubes<\/li>\n\n\n\n<li>Cheese flavored chips<\/li>\n\n\n\n<li>Ready-made sauces<\/li>\n\n\n\n<li>Bread spreads such as filet americain<\/li>\n<\/ul>\n\n\n\n<p>So always check the <strong>ingredient list<\/strong> and learn to recognize what is included in milk, such as <em>milk powder<\/em>, <em>whey powder<\/em> or <em>casein<\/em>.
