It is important not to assume that milk alternatives are the same as cow's milk. <ul><li>Cow's milk is a very nutrient-dense food, and fortified plant milk doesn't always cover all nutrients. </li><li>Cow's milk contains lactose, a naturally occurring sugar, while milk alternatives often contain added sugar, which is harmful to our health.</li></ul>If you do decide to use a dairy-free alternative, you won’t necessarily be missing out on vital nutrients if you eat a balanced diet.

Cow milk and the alternatives

Dairy-free alternatives for milk include soy, almonds, cashews, hazelnuts, coconuts, macadamia nuts, rice, flax, oats or hemp. The main ingredient is processed and diluted with water. Soya milk is the best replacement for cow's milk in terms of protein. But the quality protein is substantially lower than milk, making it less suitable for children and the elderly.

Those with lactose intolerance can drink small amounts of cow's milk.A nutrition scientist carried out a study comparing the symptoms of people with lactose intolerance when they drank two cups of soya milk, raw milk or regular milk every day. He found many of them didn’t suffer severe symptoms.

There is a link between saturated fat and heart disease, but whole milk only contains around 3,5% fat, semi-skimmed around 1,5% and skimmed milk 0,3%.Only very high milk intake can be harmful, but there's no research to suggest that moderate consumption is bad for you.

The estrogen levels of cows increase 20-fold when they are pregnant. Although one study linked estrogen levels to breast, ovarian and uterine cancers, ingesting hormones through cow's milk is no cause for concern.Researchers found estrogen levels only affect the reproductive systems in mice when supplemented with 100 times the levels found in cow's milk.

<ul><li>If children between one and three consume half a pint of milk, <a href="https://www.nhs.uk/live-well/eat-well/milk-and-dairy-nutrition/">they will consume enough calcium</a> for healthy bone development. </li><li>Calcium is crucial during our adolescence for the development of bone strength. If you don't get enough calcium in your teenage years, you run a higher risk of bone weakness.</li><li>For adults, research is conflicting on whether cow's milk helps to keep bones healthy.</li></ul>

As the only animal to drink the milk of another species, humans have an unusual relationship with the white stuff. Most other animals are weaned off milk in infancy, once we start to need more complex foods. So why do humans keep drinking it?
