How Ultra-Processed Foods Are Killing Us

In the current issue of the online Journal of the World Public Health
Nutrition Association (of which I am a charter member), Carlos Monteiro, a
professor at the University of São Paulo writes, "The big issue is
ultra-processing." Because his commentary is so lengthy, I am taking the
liberty of extracting pieces from it, not always in the order presented.

The most important factor now, when considering food, nutrition and
public health, is not nutrients, and is not foods, so much as what is done to
foodstuffs and the nutrients originally contained in them, before they are
purchased and consumed. That is to say, the big issue is food processing—or,
to be more precise, the nature, extent and purpose of processing, and what
happens to food and to us as a result of processing.

Monteiro makes it clear that all foods and drinks are processed to some
extent. Fresh apples are washed and, sometimes, waxed. Drinking water is
filtered. Instead, he distinguishes three types of processing, depending on
their nature, extent, and purpose:

• Type 1: Unprocessed or minimally processed foods that do not change the
nutritional properties of the food.

• Type 2: Processed culinary or food industry ingredients such as oils,
fats, sugar and sweeteners, flours, starches, and salt. These are depleted of
nutrients and provide little beyond calories (except for salt, which has no
calories).

• Type 3: Ultra-processed products that combine Type 2 ingredients (and,
rarely, traces of Type 1).

The purpose of Type 3 ultra-processing is to create:

durable, accessible, convenient, attractive, ready-to-eat or
ready-to-heat products. Such ultra-processed products are formulated to
reduce microbial deterioration ('long shelf life'), to be transportable for
long distances, to be extremely palatable ('high organoleptic quality') and
often to be habit-forming. Typically they are designed to be consumed
anywhere—in fast-food establishments, at home in place of domestically
prepared and cooked food, and while watching television, at a desk or
elsewhere at work, in the street, and while driving.

Monteiro argues: "the rapid rise in consumption of ultra-processed food and
drink products, especially since the 1980s, is the main dietary cause of the
concurrent rapid rise in obesity and related diseases throughout the world."

As evidence, he notes that ultra-processed products as a group are:

• Much more energy-dense than unprocessed and minimally processed foods
and processed culinary ingredients taken together.

• [Contain] oils, solid fats, sugars, salt, flours, starches [that] make
them excessive in total fat, saturated or trans-fats, sugar and sodium, and
short of micronutrients and other bioactive compounds, and of dietary fiber.

• Relatively or even absolutely cheaper to manufacture, and sometimes—not
always—relatively cheaper to buy.

• Often manufactured in increasingly supersized packages and portions at
discounted prices with no loss to the manufacturer.

• Available in 'convenience' stores and other outlets often open late or
even 24/7, and vended in machines placed in streets, gas stations, hospitals,
schools and many other locations.

• The main business of transnational and big national catering chains,
whose outlets are also often open until late at night, and whose products are
designed to be consumed also in the street, while working or driving, or
watching television.

• Promoted by lightly regulated or practically unregulated advertising
that identifies fast and convenience food, soft drinks and other
ultra-processed products as a necessary and integral part of the good life,
and even, when the products are 'fortified' with micronutrients, as essential
to the growth, health and well-being of children.

Overall, he says:

Their high energy density, hyper-palatability, their marketing in large
and super-sizes, and aggressive and sophisticated advertising, all undermine
the normal processes of appetite control, cause over-consumption, and
therefore cause obesity, and diseases associated with obesity.

His groups the main points of his argument in three theses:

• Diets mainly made up from combinations of processed ingredients and
unprocessed and minimally processed foods, are superior to diets including
substantial amounts of ultra-processed products.

• Almost all types of ultra-processed product, including those advertised
as 'light', 'premium', supplemented, 'fortified', or healthy in other ways,
are intrinsically unhealthy.

• Significant improvement and maintenance of public health always
requires the use of law. The swamping of food systems by ultra-processed
products can be controlled and prevented only by statutory regulation.

Lest there be any confusion about the significance of this proposal for
public health nutrition, an accompanying editorial (unsigned but assumed to
be by Geoffrey Cannon) poses a serious challenge: "Nutrition science: time to
start again."

This editorial is about the significance of food processing, and in
particular of 'ultra-processed' food and drink products. It is also about the
nature, purpose, scope and value of nutrition science, which as
conventionally taught and practiced, is now widely perceived to have run into
the buffers or, to change metaphor, to have painted itself into a corner.

The editorial argues that nutritionists' focus on nutrients, rather than
foods, has led to the assumption that if foods contain the same nutrients,
they are the same—even though it is never possible to replicate the
nutritional content of foods because too much about their chemical
composition is still unknown:

This notion is an exquisite combination of stupidity and arrogance, or
else of intelligence and cunning. For a start, similar results can only be of
those chemical constituents that are at the time known, and actually measured.

These are important ideas, well worth consideration and debate. I am struck
by their relevance to the latest survey of soft drink availability in
American elementary schools. Despite the efforts of the Clinton Foundation
and the voluntary actions of Coca-Cola and Pepsi-Cola, the availability of
soft drinks to young school children increased from 49 percent to 61 percent
just in the year from 2006-07 to 2008-09. Soft drinks, in Monteiro's terms,
are ultra-processed. Doing something about them requires statutory regulation.

Consideration of the effects of ultra-processing might help us look at what
we feed our kids in a more constructive way. This is important work.
