Replace milk, yogurt, custard and cream with lactose-free varieties. In this way, you will remove a lot of lactose from your day at once without completely changing your diet.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Build up your portions slowly<\/h4>\n\n\n\n<p>Everyone has their own threshold. Start with small amounts and see how your tummy reacts. Increase the portions step by step until you know what is comfortable for you.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Make smart choices within dairy<\/h4>\n\n\n\n<p>Not all dairy products contain the same amount of lactose. Fermented products such as yogurt are often more easily tolerated and many old, hard cheeses are naturally low in lactose.

Find out how it works, what forms there are and what to look out for in <strong><a href=\"https:\/\/noomooo.com\/en\/what-are-lactose-intolerance-pills\/\">What are lactose intolerance pills<\/a><\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Read labels without guesswork<\/h4>\n\n\n\n<p>Lactose and dairy ingredients are often hidden in processed products. By learning to read labels, you can avoid surprises. Practical tips and lists of designations can be found in <strong><a href=\"https:\/\/noomooo.com\/en\/check-ingredient-list-milk\/?utm_source=chatgpt.com\">Check the ingredient list<\/a><\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Work with a simple food diary<\/h4>\n\n\n\n<p>Write down what you eat, the portions and how you feel.
