Is milk the best source of calcium? Is trim milk watered down? Can you drink milk if you are lactose intolerant? Read on for some milk and dairy myths answered by nutrition expert Laura Anderson.
When most people think about dairy, their first thought may be that it is a source of calcium, and that it’s good for strong bones. Others however, hold fairly different opinions when it comes to the health benefits of dairy, influenced by outdated research or incorrect information.
Water is never added to our lite or trim fresh milks. The only difference is the proportion of cream we remove to get the right fat level.
This gives a lighter tasting milk while still providing a rich bundle of essential nutrients, making it a great choice if you’re looking for a lower calorie option.
No sugars are added to our fresh plain milk in New Zealand. When you look at a label on your bottle of milk, trim milk may contain around 0.2g more naturally occurring milk sugar (lactose) than full fat milk, per 100mL.
This is because when you reduce fat levels, the levels of everything else within the milk, including protein, calcium and lactose will increase proportionally. So while lowering the fat results in a slightly higher level of sugar, it’s not because it has been added!
People with lactose intolerance do not need to avoid dairy food, which is different to dairy protein allergy where all dairy must be avoided.
Most people with clinically diagnosed lactose intolerance can consume up to a glass of regular milk and other dairy products without any concerns, particularly cheese and yoghurts because they are naturally low in lactose, or when consumed as part of a meal.
If you think you might have lactose intolerance, see your health professional for a proper diagnosis and dietary advice tailored to your individual needs.
Bone strength is related to the density of bone; so in general, the denser your bones the stronger they are. Osteoporosis is a condition of low bone density associated with a higher risk of bone fracture.
Calcium is one of the main dietary factors affecting bone density. Public health experts and scientific authorities such as the International Osteoporosis Foundation recommend consumption of milk and dairy products as the most readily available dietary sources of calcium for the development and maintenance of strong bones.
All our fresh milks are exactly that, fresh! We don’t make them from milk powder as it wouldn’t taste as fresh or be energy efficient!
It takes a lot of energy to turn milk into milk powder. In New Zealand we are lucky to have plenty of milk around so can easily bottle fresh milk. We do make a variety of dairy products such as milk powders & UHT milks which last a lot longer than fresh milk.
But the majority of these powders & UHT products are exported overseas often to countries where they may have limited availability of fresh milk. In some countries where access to fresh milk is challenging, some companies sell reconstituted milk that is made from milk powder.
This is an interesting theory, but one that isn’t supported by science. It suggests that the human body hasn’t been ‘designed’ or hasn’t evolved to tolerate the milk of another animal.
However, the evolution of our culture and genetics tells another story - beginning with the domestication of animals, when farming replaced hunting and gathering around 10,000 years ago.
