What is a Dairy Free diet?
A dairy-free diet eliminates all foods made from or containing milk and milk-derived ingredients, such as butter, cheese, yogurt, and cream. It's essential for people with lactose intolerance, milk allergies, or those who prefer plant-based alternatives. Common dairy substitutes include almond, soy, oat, and coconut-based milks and cheeses. While dairy is a major source of calcium and vitamin D, these nutrients can be replaced through fortified foods or supplements. Many people find going dairy-free helps reduce digestive issues, acne, or inflammation, but balance and proper nutrient intake remain key for long-term health.
