Dairy foods and their plant-based alternatives are a major everyday source of calcium, protein and, when fortified, vitamin D — nutrients central to bone health. HealthHub notes that milk in particular provides “calcium, protein, fortified vitamins and more.”
Common dairy foods and alternatives
Milk, cheese, yoghurt and kefir are the most familiar dairy foods. Plant-based alternatives include soy, oat, almond and coconut milks, along with fortified plant-based yoghurts — soy milk is nutritionally closest to dairy milk, including a comparable protein level.
Health influence
Benefit: regular dairy intake supports bone density throughout life, and fermented dairy such as yoghurt and kefir also contributes live cultures linked to gut health.
Watch for: full-fat dairy is a significant source of saturated fat, and regularly choosing higher-fat varieties can contribute to raised LDL cholesterol. Not all plant-based alternatives match dairy's calcium and protein unless fortified, and flavoured versions can carry substantial added sugar.
Practical choices
- Choose reduced-fat or low-fat dairy most of the time to limit saturated fat.
- If choosing a plant-based alternative, pick one fortified with calcium and vitamin D.
- Watch for added sugar in flavoured milks, yoghurts and plant-based drinks.
- Include a fermented option such as plain yoghurt or kefir regularly for gut health.
