Milk jury still out
on whole v low-fat
WELL RESEARCHED: Numerous studies of young children have found the
same or greater rates of weight gain with the consumption of reduced-fat
milk compared with whole milk.
By SARAH BERRY
FOOD FASHION has shifted
away from low-fat in recent
But with low-fat still the focus
of public health messages, some
are questioning whether such
recommendations are right.
A paper, Three Daily Servings
of Reduced-Fat Milk: An
published recently in the
Journal of the American Medical
Remarkably few randomised
clinical trials have examined the
effects of reduced-fat milk (0 per
cent to 2 per cent fat content)
compared with whole milk on
weight gain or other health
outcomes,'' the paper's authors
David Ludwig and Walter
Willett of Harvard Medical
What has happened instead is
a presumption that the lower-
calorie content will equate to a
lesser likelihood of weight gain''.
But this, they contend, is not
the case and point to numerous
studies of young children,
adolescents and adults that
found the same or greater rates
of weight gain with the
consumption of reduced-fat milk
compared with whole milk.
They reasoned that perhaps
people compensate or over-
compensate for the lower calorie
content of reduced fat milk by
eating more of other foods''.
The typical example is the
extra biscuit or bit of cake with
your low-fat latte. This is a
double whammy, they said.
A low-fat, high-glycemic diet
may not only increase hunger
but also adversely affect energy
expenditure compared with
diets with a higher proportion of
Accredited practising dietitian
and Dietitians Association of
Australia spokeswoman Kate
DiPrima believes the message
they are promoting is
What really worries me
[about these studies] is that they
look at one item,'' DiPrima said.
Rather than looking at the
milk plus yoghurt and cheese,
plus a pizza and something
else,'' they blame low-fat milk.
The odd flat white on full-
cream is fine, she said, but with
seven in 10 Australian men and
more than six in 10 women
overweight, she fears people
adding full-cream milk on top of
everything else'' may be
In an op-ed titled In Defence of
Skim Milk American dietitian,
Maryann Tomovic Jacobson also
defended reduced-fat dairy.
I don't choose skim milk for
weight control, I drink it
because I want to leave more
room for healthier fats that
come from plant foods and fish,''
For example, my morning
oatmeal includes a handful of
walnuts which adds a hearty 20
grams of fat and that keeps me
nice and satisfied. Do I really
need to add milk fat on top of
It's a fair point. And one that
DiPrima and Australia's
regulating bodies agree with.
Our position is we're guided
by evidence-based medicine,''
The National Health and
Medical Research Council
regulates the guidelines and [for
the updated guidelines released
in February this year] they went
through hundreds of studies...
The present guidelines
recommend reduced-fat dairy for
everyone over the age of 2.
But reduced-fat dairy
continues to cop criticism.
Ludwig and Willett said that
to help palatability, many skim
milks are sweetened. While
sweetened reduced-fat milk
lowers saturated fat by 3g it
increases sugar by up to 13g a
A separate Harvard study of
18,555 women has also found
high intake of low-fat dairy
foods may increase the risk of
anovulatory infertility, whereas
intake of high-fat dairy foods
may decrease this risk.''
Based on such studies,
American doctor, author and
Arizona Center for Integrative
Medicine director Andrew Weil
said: I no longer recommend
choosing low-fat dairy products.
I believe the healthier choice is
high-quality, organic dairy foods
Ludwig and Willett take this
statement a step further:
Humans have no nutritional
requirement for animal milk, an
evolutionary recent addition to
As for whether we need milk
for bone health, they argue that
the recommendations are likely
to be over-estimated and
throughout the world, bone
fracture rates tend to be lower in
countries that do not consume
milk compared with those that
do. . .''.
Nevertheless, milk provides
significant amounts of protein
and other essential nutrients
and may confer health benefits
for children and adults with poor
overall diet quality.''
Indeed. Dairy contains
calcium, protein, carbohydrate,
vitamin A, vitamin B12,
potassium, phosphorous and
More than 80 per cent of
Australians of all ages eat or
drink a dairy food in any given
day and each Australian drinks
about 104 litres of milk a year.
That is unlikely to stop given
the arguments on both sides but
which carton to choose?
The key is small portions
sizes, balance and to follow the
guidelines,'' said DiParma who
opts for reduced-fat for herself.
Remember, she said, it's not
just looking at one food''.
The optimal level of milk
consumption will likely vary
among individuals, depending
on overall diet quality,'' Ludwig
and Willett said.
