Calcium-rich foods better for bones

Calcium-rich foods better for bonesResearchers in the US studied the calcium intakes of 183 post-menopausal women and measured their bone mineral density (BMD) at different parts of their skeleton.
Total calcium intakes were calculated from a seven-day food diary plus information about use of dietary supplements.
It was found the women who obtained their calcium primarily from foods had significantly higher BMD than those who predominantly obtained calcium from supplements.
The researchers point out that it may be other nutrients in calcium-rich foods that are stimulating the increase in BMD, although it could also be that dietary calcium is better utilised by the body than supplemented calcium

How to choose: Milk

How to choose: Milk
Milk
We guide you through the milk aisle of the supermarket to help you decipher which type of milk is best for you.

Calcium

The recommended dietary intake (RDI) for calcium for most adults is 1000mg per day, but for women over 50 and for men over 70 that increases to 1300mg.
That’s not easy to achieve without milk and dairy foods. A serving equals one 250ml glass of milk, a 150g pottle of yoghurt or two slices of cheese (40g).  A cup of milk can provide from around 280mg up to 500mg of calcium.

How to choose: MilkFat

Full-cream and standard milks contain around 2.4% saturated fat (that's 2.4g per 100ml).
That equates to 6g saturated fat in a glass. Because most of us are getting too much saturated fat, we’re advised to go for milks with less of it.
The lower-fat milks will taste a little different. If you’re not so keen at first, think of it in the same way as when you’re offering a new food to a child: we often just need to taste something a number of times to become accustomed to that new taste. Given you could be saving your arteries from clogging and it could help with weight control, it’s worth doing.
Type of milk Label colour Fat % Saturated

Full cream Purple 4.0% 2.4% 700kJ
Standard  Blue 3.3% 2.4% 640kJ 
Reduced fat / lite Light blue  1.5% 1.0%  500kJ
Trim  Green 0.5%  0.3% 430kJ
Extra / super trim Light green  0.1% <0.1% 360kJ
* kJ in one standard glass (250ml)

Protein

A glass of standard or reduced-fat milk provides 8-9g of protein. It’s helpful to add protein to our diets throughout the day, and not just when we sit down to our evening meal, as it helps us feel fuller for longer and can be important after exercising.
Ultra-filtered milks, like Sun Latte and Anchor Xtra have around 15g of protein in a glass. That’s because a lot of the water, lactose and fat has been filtered out, so the proportion of protein (as well as calcium) is higher.

Fortified milks

There are a range of fortified milks available, mainly focusing on nutrients involved in bone health. Anlene has the broadest range of nutrients which are all important in bone metabolism: it has added calcium, magnesium, zinc, vitamin D and vitamin K.
Because it contains vitamin K, which is unique to Anlene, it is not suitable for anyone on the prescription medication Warfarin without first consulting their GP, and this is stated on the label.

Powdered milk?

Milk powder is just milk that’s been dehydrated.
You may want to stock milk powder in your pantry as it’s great for emergencies; it’s easy to add skim milk powder to shakes and other foods without making the food too filling; and it’s a very economical alternative to fresh milk.
If you’re on a tight household budget and you’re big users of milk, it could make a significant difference. Instead of paying 55 cents a glass for a low-fat milk, you could pay as little as 20 cents a glass. If your household consumed 2 litres of milk a day (that’s only 8 glasses), you could spend $30 a week or more on milk, but if you changed to powdered milk you could cut that to only $11.
Be sure to follow the directions on the pack so that you get the same nutrition as you would from fresh milk. And once it’s made up, keep it in the fridge and use it within a few days.

How to choose

  • Fat: To reduce your saturated fat intake, learn to like the reduced fat milks with 1.5% total fat or less. That’s light blue at least.
  • Calcium: The milks with 500mg calcium per 250ml glass (that’s 200mg/100ml) are a good idea for anyone who doesn’t think they’re getting as much calcium as they ought, and I’d definitely recommend them for women over 50 and men over 70 where the RDI is higher still. If you’re buying soy or an alternative milk, ensure it has added calcium.
  • Protein: It’s good to include some protein with each snack or meal you have, so if you’re choosing alternatives to cows' milk look for ones with some protein in them.
  • Allergy or intolerance: These days you have quite a lot to choose from; check the fat and calcium content before making your choice.
  • Budget: If you’re on a tight budget, consider the store brands which tend to be cheaper, or the powdered milks which are really cheap.
  • Taste: For different tastes you may want to try some of the alternatives to cows' milk. You don’t have to have the same thing all the time! If you’re accustomed to a higher-fat cows' milk and you don’t like the taste of the lower-fat cows' milk, work on it!

Milk for young children



Milk for young childrenIs milk safe for young children, and if so, what type of milk is best?
Cows' milk should not be given to infants under 12 months of age. Their digestive systems are still developing and before 12 months there is a risk of stomach bleeding if fed cows' milk. There is also a risk of developing an allergy, especially in families with a history of allergy. Only breast milk or infant formula should be offered.
After 12 months of age, milk is an important addition to the diet. This can be cows' milk or soy milk if fortified with calcium. 500-600mls a day of whole/standard milk is recommended for one and two year olds. Milk is a good source of nutrients and energy for toddlers, but they shouldn’t have too much or they won’t have capacity in their small stomachs for the other foods they need to balance their diet.
Before two years of age, toddlers need a higher-fat milk (dark blue) because they have such high energy needs, but after two years children can change to lower-fat milks.

How to get enough calcium

How to get enough calciumMilk and dairy products, as well as being a source of protein and providing a range of vitamins and minerals, are the main source of calcium in a typical Kiwi diet.
Because of this we’re advised to get at least two servings (if not more) of milk or milk products every day. A serving equals one 250ml glass of milk, a 150g pottle of yoghurt or two slices of cheese (40g).
Calcium intake is essential for developing the strongest bones we can when they are growing (up to our mid-twenties) and also for maintaining their strength throughout our lifetime.
If we don’t get enough calcium our bones suffer as their stores will be used for the other esss calcium has, like muscle contraction, nerveential function transmission and blood clotting.
Osteoporosis is a condition where parts of the bones become quite porous and are prone to fracture easily.
The recommended dietary intake (RDI) for calcium for most adults is 1000mg per day, but for women over 50 and for men over 70 that increases to 1300mg.
That’s not easy to achieve without milk and dairy foods. You can see from the table below that a cup of milk can provide from around 280mg up to 500mg of calcium.
High calcium foods include:
  • 1 cup of yoghurt = can range from 140mg to 550mg, so choosing wisely can make a huge difference to your calcium intake each day!
  • 40g cheddar or edam cheese = 300mg
  • Small tin canned sardines = 490mg+
  • 1 cup of tofu = 270mg
  • 1 cup fortified breakfast cereal = 200-400mg
Many other foods also provide a small amount of calcium:
  • 1 orange = 35mg
  • 10 almonds = 30mg
  • 1 cup steamed broccoli = 60mg

Lactose intolerance and milk allergy

Lactose intolerance and milk allergy What are they and how do you get enough calcium in your diet if you have one?

Lactose intolerance

Lactose intolerance is the inability to digest lactose, a naturally occurring sugar in milk. This can be a permanent intolerance, which is caused by the genetic inability to produce the lactase enzyme which breaks down the lactose.
It could also be a temporary intolerance, which can be caused by an infection damaging the lining of the intestine where the lactase is produced.
If the lactose is not broken down it accumulates in the intestine, taking water from the surrounding tissues, which can lead to the uncomfortable symptoms of bloating, cramping and diarrhoea.
For people with lactose intolerance there are a number of options: Liddells lactose-free UHT milk contains full cream cows' milk and the enzyme lactase; or for a fresh milk, Sun Latte is also well-tolerated as this ultra-filtered milk is very low-lactose.

Milk allergy

Cows' milk allergy is a hypersensitivity to cows' milk protein, which involves the body’s immune system.
Milk is one of the most common food allergens for children, although most children will grow out of it by 3 years of age.
People allergic to cows' milk are often allergic to goats' milk as well; it depends on which protein component has caused the allergy. Some components are the same in both milks.

Milk alternatives

To make soy or rice milk the soy beans, or rice, are soaked so they become swollen, then they’re ground with more water.
The mixture is brought to the boil and then filtered. Like cows' milk, these milks may be fortified with vitamins and minerals.

Soy milk

Most, but not all, are fortified with calcium, making them a suitable alternative for people with lactose intolerance or cows' milk allergy; anyone who wants to include more soy in their diet; or anyone who just likes them.
Soy milks are naturally very low in saturated fat and contain no lactose. Not made from animal products, they are also suitable for vegetarians.
One to two serves of soy each day can provide health benefits for all of us, so soy milk may be an easy way to achieve that. (For more on soy: Soy: What's the latest? )

Rice milk

For people with coeliac disease, rice milk may be a good alternative; most are gluten-free, but always check the labelling first.
It’s also suitable for anyone with cows' milk allergy or lactose intolerance, for vegetarians, or anyone who just likes the taste for a change.
Rice milk is naturally very low in protein, although the Vitasoy protein-enriched rice milk has nearly 4g protein in a 250ml glass.

  • 51 years and over: 1300mg

Requirements for males:

  • 14–18 years: 1300mg
  • 19–70 years: 1000mg
  • 71 years and over: 1300mg

Good sources of calcium:

  • 1 cup Trim milk = 375mg
  • 1 cup Calci Trim or Xtra milk = 500mg
  • 150g pottle unsweetened yoghurt = 180mg
  • 40g Edam cheese = 308mg
  • 1/4 cup cottage cheese = 37mg
  • 1 can sardines (100g) = 550mg
  • 1 can baked beans (425g) = 51mg
  • 10 almonds = 30mg
  • 1 cup cooked broccoli = 59mg

Ask the experts: Mediterranean diet

Do you get enough calcium on a Mediterranean diet?
Question icon"The Mediterranean Diet is promoted as one of the healthiest, but it never mentions dairy products. On the Mediterranean Diet, how does one get enough calcium? I know other foods provide some calcium, but here in NZ we are given the impression that diary products are necessary for adequate calcium intake."
Valerie
Answer iconWe asked nutritionist Cindy Williams to respond:
Ask the experts: Mediterranean diet“The Mediterranean diet is based on the food patterns typical of Greece, Crete and southern Italy in the 1960s. These people ate lots of vegetables, legumes, fruit, unrefined grains and olive oil with a moderate intake of fish, eggs, chicken and dairy. The Mediterranean Diet recommends two serves of dairy a day. In a traditional Mediterranean diet this would have been from yoghurt or white cheese such as goats' cheese.
If the only calcium we got from food was in dairy products, two dairy serves would not be enough – the guidelines from the Ministry of Health recommend 1000mg a day which is closer to 3-4 dairy serves. But while dairy is the richest source of calcium, there is also a good amount of calcium in the large serves of green vegetables, dried beans, whole grains and nuts recommended on this diet. A cup of cooked broccoli provides 30mg calcium, a cup of chickpeas 100mg, one egg or 15 almonds around 50mg and a cup of spinach 100mg (although the latter is not as well absorbed). These may seem small amounts but they all add up.
Generally if you have a varied diet you will get enough calcium by including two or more (high-calcium) dairy serves in your day (the recommendation for Kiwis is at least two serves). We highlight dairy as it is traditionally an important source of calcium for Kiwis. For other ways to get a high calcium boost, try a small can of salmon (with bones) or sardines on grainy toast or a cup of calcium-enriched soy drink.”
