Outline: Why Do We Need Large-Scale

Changes to Improve Our Diets?

• Introduction: the nutrition transition and major mismatches: modern technology vs. inherited biological preferences

• Physical activity: a major concern but not the solution

• The modern food system and how it has shaped our diet

• Major dietary shifts of the past 2-3 decades

• Regulatory and tax options: global lessons from Chile and Mexico

• Chile may be the first country to reverse obesity and all the diet and obesity-related NCDs, but there are key gaps to fill.

Role of Our History

Core biochemical and

physiologic processes

have been preserved

from those who

appeared in Africa

between 100,000 and

50,000 years ago.

Biology Evolved Over

100,000 Years

Modern Technology has taken

advantage of this biology

Sweet preferences Cheap caloric sweeteners, food

processing create habituation to

sweetness

Thirst, hunger/satiety

mechanisms not linked

Caloric beverage revolution, sweetening

of beverages consumed

Fatty food preference Edible oil revolution — high yield oilseeds,

cheap removal of oils, modern processed

food/restaurant sector

Desire to eliminate

exertion

Technology in all phases of work and

movement reduce energy expenditure,

enhance sedentarianism

Mismatch: Biology which has evolved over the

millennia clashes with modern technology

Stages of the Nutrition Transition

Pattern 4

Chronic Disease (NCD’s)

Reduced body fatness

& NR-NCD’s, improved

disease prevention

Obesity & NR-NCD

emerge, and medical

cures keep us alive

MCH deficiencies,

weaning disease,

stunting

Nutritional

deficiencies

emerge, stature

declines

Lean &

robust, tall,

high disease

rate

• Reduced refined carbs, sugar

• Unhealthy fats↓, increased

fruit, veg, whole grains,

legumes

• Drink water, low kcal bev.

• Replace sedentarianism

with purposeful increases

in activity

• Increased fat, sugar,

processed foods diet

• Drink sugary beverages, juices

• Shift in technology of work and leisure

• Sedentarianism high

• Starchy, low

variety, low fat,

high fiber diet

• Drink water

• Labor-intensive

work/leisure

• Monoculture ag.

• Cereals

dominate diet

• Drink water

• Labor-intensive

Pattern 2

Famine

High fertility, high

MCH mortality,

low life expectancy

Urbanization, economic growth, technological changes for work, leisure, & food processing, mass media growth

Pattern 1

Collecting Food

Low fertility,

low life expectancy

• Diverse wild plants

& animal food diet

• Drink water

• Labor-intensive

Pattern 3

Receding Famine

Slow mortality

decline

Accelerated life expectancy,

shift to increased NR-NCD,

increased % disability years

• Our work in China and elsewhere has convinced me

that a major component of global obesity increase is

linked with reduced physical activity at work, home, and

transport along with increased sedentarianism

• At the same time we cannot turn back the clock on

technology at work, home, transportation, leisure

• Thus the need is to create new activity—marginal gains

at work and home, but major increased activity must

come from purposeful recreational movement, energy

expenditure. Very hard to offset modern diets’ effects.

Physical Activity:

A Major Cause, Not a Solution

Page 10: The Nutrition Transition and Global Food System Dynamics ... · 7/1/2017  · Ready-to-heat (RTH) Not consumed Frozen dinners or pizza, frozen as purchased, requires only a small

• Most dietary guidelines focus on increased produce, whole grains,

minimal red meat, healthy fats, more plant food.

• Michael Pollan: “Eat food. Not too much. Mostly plants.”

• Monteiro, PAHO guidelines, others pushing the same, possibly

could interpret PREDIMED results similarly as a push for minimally

or unprocessed food-based diet

• The reality: the enormous rapid shift in our food system discussed

next runs completely counter to these pushes.

• Unanswered question: Can we have any type of highly processed

foods as part of a healthy diet? Or does such a diet with excessive

highly processed food even exist?

• All this is being played out in nutrient profiling and FOP policies will

note later but seeing negative and positive logos as separate but

joint efforts emerging finally to address both sides of this issue—

remove junk food, promote truly healthy food.

What is driving our increased obesity globally

• The modern agricultural and entire food system

has changed remarkably not only in the US and

higher income countries but globally.

• Every village, location in the world now faces

many of the same packaged and processed

junk foods and beverages

• Trend in disappearing fresh markets being replaced by small stalls,

convenience stores and supermarkets all selling ultra-processed foods

and beverages

• Mexico and China: packaged foods with bar codes based on nationally

representative 24-hour recalls surveys with questions probing this issue

– 58% of kcal Mexico in 2012 and 29% in China in 2011 (growing by

50%/year)

• Latin America/Gulf states: first major growth, now Asia and urban Africa;

high penetration into all African and Middle East communities now

• Major shifts in types of foods and integrated marketing strategies used by

food industry sectors across global regions with Latin America being

penetrated most completely and earlier than Africa and Asia

• Global agribusinesses

• Retailers

• Food manufacturers

• Large restaurant chains

• Walmart: completely post-WWII phenomena

with all growth from 1970 onwards

• Carrefour: 1960’s onward

• Ahold: (began as Albert Heijn) and expanded

in early 1900’s, as did Tesco with basic foods.

• Most major growth as chains occurred after WWII

• Our focus is not only on these global chains but all the domestic clones

across the globe in low and middle income countries

• Packaged processed food growth, especially highly or ultra-processed

food is mainly a recent phenomena of the last 30-50 years with modern

food science and related food manufacturer revolution.

• Total caloric intake = f(Meal Size(G) x Eating

Frequency(#) x energy density of the meal (kcal/g))

• Meal sizes ↑: US, UK, Germany, other countries

• Eating Frequency ↑↑: large increase documented in few

countries, seeing new global increases. Snacks are

significantly greater energy density

• Energy density ↑↓ : biggest shift toward higher number

& size snacks of higher energy density and excessive

added sugar and refined carbs; caloric beverages

increased also in total volume with comparable results

for children

Total Caloric Intake Is a Combination

of Three Components

• Use classic total derivative approach by creating partial

derivatives for each component and using them to

create total derivative

• Major finding was that the increases in energy intake in

the last century were driven more by increased eating

frequency than meal portion size (note we looked at

total meal portion size and not one dish).

1. Adult obesity precedes child obesity: conjecture

relates to the rapid decline in adult activity along with

the more recent food system shifts

2. Rightward shift in BMI at all ages—age-period-cohort

and other research suggests 8-10 kg increase over

past 10-20 years (e.g. Jaacks et al, IJE 42:828-837)

3. Waist circumference at each BMI level is increasing

4. Remember much higher body fat proportion, visceral

fat among many LMIC subpopulations. Also increased

NCD susceptibility at lower BMI’s

What Does All This Mean for Global

Obesity?

• Major Tools considered to date for obesity prevention at the macro/regulatory level:

– Economic tools: prices(taxation), subsidies?, trade controls?

– Labeling: FOP labeling approaches being used; considering claims restrictions-ideally linked with marketing controls

– Marketing controls and restrictions: kids only vs overall

– Restrict foods in selected institutions(e.g. schools, hospitals,etc) but really minimal evidence in any country of major impact of major feeding changes and their impact (especially LMIC’s)

• Other aspects of our food system not addressed to date:

– Retailer change only via changes noted above to date

– Neglect of restaurant/fast food/stall sector

– Other farm system/sector changes: no sense of potential impact .

– To date, know traditional nutrition education efforts small, not possible without major marketing controls, but no sense of modern mass media/social media efforts.

• Mexican Beverage panel 2007-8: recommended taxing sugary

beverages; got all medical societies to sign on and publish document

• Series of meetings on ways to reduce added sugar, bad fats, sodium

• National Prevention Plan

• Front-of-the-package profiling: MOH, MinFinance, Mex FDA — I

chaired

• New elections, new President, Min of Health with strong industry ties

and Bloomberg involvement with major public campaign

• 2 taxes instituted, fought off attempts to cut, constant battles with

industry over SSB tax. Surprisingly little over junk food tax.

• Media strategy: Create public debate

through press conferences (1xweek),

public actions/performances (1xmonth)

and newspaper ads (2xweek in Oct.)

• Engagement with decision-makers and

lobbying:

- Actor mapping

- Identification of champion(s)

- Relationship building across parties,

ministries and Congressional committees

- Mini public campaign targeting Congress

- Tracking industry lobbying (responding

or exposing as necessary)

• International support: WHO

The Mexican tax: Leading the Way So Far and Used

to Build Basis for Taxes in Many Countries, Cities

• Passed Oct 31, 2013

• Sugar-sweetened beverages (SSB): All flavored waters

(including concentrates, powders or syrups used to prepare

flavored waters) that have added sugars will be subject to a tax

of $ one peso per liter.(≈10%)

• Junk food: All non-basic foods (chips and snacks; candies;

chocolate and cacao based products; puddings; fruit-made and

vegetable-made sweets; peanut and hazelnut butters; milk and

caramel-based sweets; cereal-based products; ice-cream and

ice-pops) with an energy density ≥275kcal/100g will be subject

to a tax of 8%.

• Evaluation of price, marketing, food purchase shifts underway

led by INSP with UNC major collaboration

• To date, price increases are being passed along.

• First year of taxes saw overall 6% decline, with 12% by month 12.

– Lowest SES group (most affected by diabetes that is untreated)

saw a 17% decline.

– Water purchases significantly increased.

• Year 2 Found an additional 4% decline

• Nonessential food taxes equally impactful in similar fashion with a

much larger year 2 decline (4.4% in first year, 16.6% in second year).

• Fought off repeated industry legal, political and extralegal efforts to

stop these efforts

Strengths: 2015-16 TV where kids 22% or more of audience

Applies to all foods and beverages and uses uniform nutrition criteria

across categories

Includes comprehensive in-school restrictions.

Restricts all characters on food packages deemed unhealthy based on a

very comprehensive set of guidelines

Strong negative logos on junk foods/beverages high in added sodium,

added sugar, added saturated fats, energy density(separate for each)

(junk food—about 50% of what retailers sell)

Strengths: new law 2017 and implementation guidelines ban 6am to

10pm

Builds on current law and adds total ban during those hours

Adds negative warning message to any media with ads for foods and

beverages with negative logos.

Chile Law Evaluation: UNC Working with

Strong University of Chile Collaborators

Planning: year later mega possibly 18% tax on all banned food-bev-

still unclear.

instituted or seeking similar tax and other

regulatory changes

• SSB taxes: Pacific & Caribbean Islands, S Africa,

Thailand, Phil., others

• Except Chile and Mexico—no exploration of other taxes

• Will reducing junk food/beverages be enough? I doubt it

• Marketing/FOP: Chile the leader, others are following

• FOP: few countries combining negative Argentinean

with push for Keyhole/choices type real healthy food

• Ultimately we must figure a way to get to a healthy diet

to truly succeed.
