foods are better for you
False. They have no value for healthy people who have enough to eat. Although the world's
important nutritional problem is protein-energy malnutrition, it is now recognised that protein
malnutrition is unlikely in otherwise healthy people who have enough food to eat, even where
foods with relatively low protein content and quality are part of the staple diet. For some
the WHO (World Health Organization) recommendation for minimal protein intake for adults
been 0.5 gram per kilogram body weight per day, but this has recently been increased to 0.6
in a recommendation from an International Union of Nutrition Sciences (IUNS) committee.
Australia, United Kingdom and United States recommendations have been one gram per
per day for adults, which provides considerable safety margin. For all this, Australian adults
commonly consume more than 1.5 gram protein per kilogram of body weight per day.
Against such a background, there is no argument for protein-fortified or supplemented
foods in a
country like Australia.
Occasionally, increased protein intake during convalescence may be worthwhile for people
excessive protein breakdown or loss as part of disease, injury or surgery.
For sports people, the only situation where an increase in protein intake might be justified
weight lifters or body builders where muscle mass is deliberately increased. Even here, the
prevailing protein intakes in the community ought to be enough. (See

There is some concern that excessive protein intakes may accelerate kidney failure. Bone
may also be reduced. We know more about desirable minimal protein intakes than desirable
maximal protein intakes.
