There are lots of essential nutrients in dairy. Each time you eat or drink dairy, you are giving your body calcium, iodine, vitamin A, vitamin D, riboflavin, vitamin B12 and zinc.
Calcium and vitamin D help your body build strong dense bones as you grow, and they keep your bones strong and healthy as you get older. Most adults need 1,000 milligrams of calcium every day. This increases to 1,300 milligrams for women aged over 50 and men aged over 70.
Not having enough calcium in your diet may increase your risk of osteoporosis. Osteoporosis is a disease of the bones, where they become brittle and weak and can break easily.
There are many reasons some people may not eat dairy foods. Some people may be allergic to cow’s milk protein – however this mostly affects infants and young children. The good news is that most children grow out of their cow’s milk allergy by the time they turn four. If you think you or your child may have a cow’s milk allergy, the best thing to do is contact your doctor. The Sydney Children’s Hospitals Network has information on milk allergy and a milk free diet
Other reasons people may choose to follow a dairy free diet include an intolerance to lactose (the natural sugar in milk) or because they are vegan. But don’t worry, because there are lots of dairy alternatives. Check out this list of dairy products and some easy alternatives you can use.
- milk – almond milk, coconut milk beverage (be careful not to confuse this with coconut milk that comes in cans, and check to make sure they are protein- and calcium-fortified) and calcium-fortified soy, rice and other cereal drinks
- butter – dairy-free margarine, cooking or baking oils, fruit purees for baking, nutritional yeast for flavor, coconut butter
- cheese – nutritional yeast, tofu
- chocolate – dark or semi-sweet chocolate, dairy-free ‘milk’ chocolate, white chocolate or pure chocolate (that is, 100 per cent cocoa or cacao chocolate). Cacao is raw and less processed than cocoa. But they are both good for you, as long as you avoid added sugars, milk and oils
- cream – there are various ways you can substitute other items such as coconut milk, milk alternatives, dairy free margarines, silken tofu, oils, nuts and seeds for cream.
- yoghurt – buttermilk alternative, coconut cream, homemade dairy-free yoghurt, pureed silken tofu, sour cream alternative.
Most people need at least 2 or 3 serves of dairy foods (or dairy alternatives) every day. But this can change depending on your age, gender and health. The Australian Government’s Eat for Health website provides information for children, adolescents, toddlers and adults. Older adults should aim for 4 serves of dairy or dairy alternative per day. A standard serve of dairy is:
- 1 cup (250 millilitres) fresh, UHT long life, reconstituted powdered milk or buttermilk
- ½ cup (125 millilitres) evaporated milk
- 2 slices or 4 cubes (40 grams) hard cheese (such as cheddar)
- ½ cup (125 grams) ricotta cheese
- ¾ cup (200 grams) yoghurt
Try to choose low-fat dairy products most of the time. While full-fat dairy products have the same amount of calcium, they are also higher in kilojoules and saturated fat. A standard serve of some common dairy substitutes includes:
- 1 cup (250 millilitres) soy, rice or other cereal drink (with at least 100 milligrams of added calcium per 100 millilitres)
- 100 grams almonds with the skin
- 60 grams sardines, canned in water
- ½ cup (125 grams) canned pink salmon with bones
- 100 grams firm tofu (check the label as calcium levels vary)
Most dairy products need to be refrigerated. The main exceptions are powdered milk products and UHT (ultra-high temperature) products, which you can store in the pantry. And, of course, ice cream, which needs to be kept in the freezer.
The best thing to do is follow the instructions on the product label. The best-before date gives you an idea of how long your dairy product will last before it starts to lose its quality (as long as you have stored it correctly). But it doesn’t necessarily mean that after this date, the dairy product is dangerous to eat or drink.
The same thing goes for dairy alternatives. Follow the directions on the packet. Some non-dairy milks need to be kept in the fridge while others are fine in the pantry. And remember, even though non-dairy milk generally lasts longer than it’s dairy counterpart, it will still sour in time.
One last thing. If you find that your dairy products and dairy alternatives are spoiling before the best before date, check your refrigerator. It may not be cold enough.
