Dangerous dietary advice on air gets me riled up

Listening to local radio on my way back from kindergarten this morning I was shocked to hear a naturopath talk about milk with such prejudice I felt compelled to ring in (or run the risk of crashing the car in a fit). She declared milk “completely compromised” by modern processing and even suggested that the immune systems of breastfed infants could be forever affected by their mothers’ dairy intakes. No mention of the need for calcium!

After taking her to task, the naturopath did say that hundreds of thousands drink milk every day with no ill effects. Dairy has too important a role in our nutrition to be so readily dismissed.

According to Dairy Australia:

New research shows people with self-perceived lactose intolerance may be at risk of poor bone health and higher rates of diabetes and hypertension.

The study published in the latest American Journal Clinical Nutrition examined the effects of self-perceived lactose intolerance – whether they were self-diagnosed or physician-diagnosed – on calcium intake and risk of specific health problems related to reduced calcium intakes[i].

The US researchers surveyed 3452 adults aged 19-70 and found participants who identified themselves as lactose intolerant had significantly lower calcium intakes than those who did not, particularly from lower intakes of dairy foods such as milk, cheese and yogurt.

Participants with self-perceived lactose intolerance were also significantly more likely to have been diagnosed with hypertension and diabetes.

Dairy Australia dietitian Glenys Zucco said people sometimes avoid milk and other dairy products due to concerns about lactose intolerance, but eliminating these nutrient-rich foods could impact diet and health.

“Dairy is a readily accessible source of calcium, and nine other essential nutrients such as magnesium, potassium and vitamin A. Inadequate consumption of these nutrients may increase the risk for chronic health problems,” she said.

 

But people who are concerned about lactose intolerance may still be able to enjoy dairy foods.

 

In 2010 a panel of experts was assembled by the National Institutes of Health (NIH) to review the available scientific evidence about lactose intolerance and health after experts expressed concern people were self-diagnosing lactose intolerance and eliminating nutrient-rich foods such as dairy from their diet.

 

A consensus paper released by the group advised that in most cases eliminating dairy foods may be unnecessary.[ii]

 

‘Even in persons with diagnosed lactose intolerance, small amounts of milk, yogurt, hard cheeses, and reduced-lactose foods may be effective approaches to managing the condition,’ the paper reported.

Ms Zucco said hard cheeses (like cheddar and parmesan) contained virtually no lactose, making them generally well tolerated.

“Yogurt is also usually well digested due to the natural bacterial cultures it contains – which help to digest lactose,” she said.

“Milk can also be tolerated well – with a little know how.  Drinking milk in small amounts throughout the day, as well as enjoying it with meals, can reduce intolerance symptoms.

“And if lactose tolerance is particularly low, there are a number of lactose-free cow’s milks available in supermarkets.”

  1. I have been reading lots of books on preventing cancer and have been upset that so many of the authors have been stating that adults should cease drinking milk due to the risk of hormones in milk potentially making someone more prone to cancer. Obviously it is best to read these sorts of books with a grain of salt because I think it all comes back to “moderation in all things”. I am sure that the benefits of milk far outway any potential danger, and even that’s questionable.
    I’m glad you rang in and made listeners aware of the facts.

    • The sad thing is that there’s often a lack of fact checking. In Australia, it’s illegal to use growth hormones in dairy cows, for example, but some health advisors (and many animal activists) just aren’t aware. I guess that’s one of the reasons for this blog – to help Australians make informed decisions about dairy.
