Summary

TLDRThis video explores the history and consequences of the USDA food pyramid, introduced in the 1990s to promote low-fat diets as part of efforts to combat obesity and diabetes. Despite its widespread adoption, the food pyramid failed to improve Americans' health, as obesity rates continued to rise. The pyramid's recommendations oversimplified nutritional science by categorizing all fats as bad and all carbohydrates as good, which led to the proliferation of low-fat products high in sugars and carbs. Recent dietary guideline revisions reflect a growing understanding of nutrition's complexity, signaling a shift away from the notion that all fats are harmful.

Takeaways

  • 📉 The food pyramid was introduced in 1992 to combat obesity and promote a low-fat diet.
  • 👩‍⚕️ Despite its popularity, obesity and diabetes rates continued to rise in the following decades.
  • ⚖️ Not all fats are bad; some are essential for good health.
  • 🍞 The oversimplification led to confusion between healthy whole grains and unhealthy simple carbs.
  • 🍭 Low-fat products often replaced fat with added sugars and carbs to maintain taste.
  • 📊 Nutrition science is evolving, and dietary guidelines are gradually changing to reflect this complexity.

Timeline

  • 00:00:00 - 00:05:05

    In 1988, Oprah showcased her weight loss journey by pulling out a wagon of animal fat, triggering a cultural shift against fat amid rising obesity and diabetes rates. The 1992 food pyramid was introduced to promote a low-fat diet, aiming to combat these health issues. However, years later, the food pyramid may have inadvertently worsened America's dietary health by oversimplifying nutritional advice and misclassifying fats and carbohydrates, leading to increased consumption of processed low-fat foods laden with sugars. Despite high public trust in the pyramid, obesity and diabetes rates continued to rise, revealing the complexities of nutrition science. Recent shifts in dietary guidelines indicate a growing recognition of this complexity, highlighting that a one-size-fits-all approach can lead to significant health mistakes.

  • 00:00:00
    - In 1988 Oprah pulled out a red wagon full
  • 00:00:03
    of greasy animal fat to show her audience
  • 00:00:05
    how much weight she had lost.
  • 00:00:06
    It was pretty gross.
  • 00:00:08
    But it became her highest rated episode ever.
  • 00:00:10
    Back then fat was the enemy.
  • 00:00:13
    It was increasingly being seen as the root cause
  • 00:00:15
    behind America's steady rise in obesity and diabetes.
  • 00:00:18
    So when the food pyramid came out in 1992
  • 00:00:21
    it was intended to help Americans fight back
  • 00:00:23
    by officially recommending a low fat diet for better health.
  • 00:00:26
    But decades later the fallout from the food pyramid
  • 00:00:29
    may have accidentally made our diets less healthy.
  • 00:00:31
    And quite possibly made the obesity
  • 00:00:32
    and diabetes problem even worse.
  • 00:00:36
    This is the story of how we got the food pyramid so wrong.
  • 00:00:43
    To address America's mounting obesity, diabetes
  • 00:00:45
    and heart disease problems in the '80s,
  • 00:00:47
    policymakers looked to what had worked before
  • 00:00:49
    on a different public health menace: smoking.
  • 00:00:52
    Back in 1964,
  • 00:00:54
    the Surgeon General's Office published a landmark report
  • 00:00:56
    that established a link between smoking and cancer.
  • 00:01:00
    In the following years rates of smoking fell dramatically
  • 00:01:03
    and tobacco related cancers started declining.
  • 00:01:06
    It was a watershed moment in public health
  • 00:01:08
    and the report was widely credited
  • 00:01:10
    with helping to save millions of lives.
  • 00:01:12
    So to try and recreate some of that success,
  • 00:01:14
    in 1988 the Surgeon General's Office published
  • 00:01:17
    a 700 page report to help fix our diet.
  • 00:01:20
    The Surgeon General boasted that the depth
  • 00:01:22
    of the science was even more impressive
  • 00:01:24
    than the legendary smoking study.
  • 00:01:27
    It was the first time officials identified the reduction
  • 00:01:29
    of fat as the number one dietary priority.
  • 00:01:32
    And when the USDA food pyramid came out
  • 00:01:34
    four years later it reflected that.
  • 00:01:36
    Fat was crammed into the tippy-top
  • 00:01:38
    along with a warning to only use it sparingly,
  • 00:01:42
    whereas a host of carbohydrate-rich foods
  • 00:01:43
    occupied the pyramid's wide bottom layer.
  • 00:01:46
    The message it sent was simple and clear:
  • 00:01:48
    carbohydrates good, fat bad.
  • 00:01:51
    The food pyramid spread far and wide.
  • 00:01:53
    It was in schools, on posters,
  • 00:01:55
    in our homes, and on our minds.
  • 00:01:58
    It was the most widely adopted guideline
  • 00:02:00
    for healthy eating in the history of the United States.
  • 00:02:03
    Over a decade after it came onto the scene
  • 00:02:05
    a Gallup survey found
  • 00:02:06
    that 82% of Americans believed the pyramid was the basis of
  • 00:02:10
    a sensible, healthful eating plan.
  • 00:02:12
    But despite the pyramid's notoriety
  • 00:02:14
    and years of educating the public about nutrition,
  • 00:02:16
    Americans didn't seem to be getting any healthier.
  • 00:02:19
    Obesity and diabetes were continuing to climb.
  • 00:02:22
    So what was going on?
  • 00:02:23
    Well, first of all it turns out
  • 00:02:25
    that the food pyramid's use fat sparingly caution
  • 00:02:27
    was an oversimplification from the start.
  • 00:02:30
    Research today makes a pretty strong case
  • 00:02:31
    that not all fats are created equal.
  • 00:02:34
    And some fats are actually good.
  • 00:02:36
    In fact too little good fat could actually
  • 00:02:39
    be leading to heart disease and obesity.
  • 00:02:41
    The very problems the food pyramid
  • 00:02:43
    had been developed to prevent.
  • 00:02:44
    And the problems with oversimplification didn't end there.
  • 00:02:47
    The wide bottom of the pyramid gave many the impression
  • 00:02:50
    that eating a diet with lots of carbs was good
  • 00:02:52
    without distinguishing between complex carbs
  • 00:02:55
    found in whole grains and oats
  • 00:02:56
    and simple carbs found in things
  • 00:02:58
    like white bread and baked goods,
  • 00:03:00
    which your body quickly turns into waist-expanding sugar.
  • 00:03:03
    The pyramid's authors actually knew this at the time
  • 00:03:05
    but they thought keeping their guidelines simple
  • 00:03:07
    was important so they left that part out.
  • 00:03:10
    And the decision proved to be a fateful one.
  • 00:03:12
    The pyramid's low fat, high carb recipe
  • 00:03:14
    would end up contributing to a low fat diet craze
  • 00:03:17
    that was about to sweep the nation.
  • 00:03:20
    Sensing the growing anti-fat sentiment
  • 00:03:22
    in the '80s and '90s the food industry responded
  • 00:03:24
    by developing thousands of reduced fat products.
  • 00:03:27
    Yogurt, chips, meats, cheeses, and cookies.
  • 00:03:32
    By 2005 low fat and fat free products
  • 00:03:34
    were a 35 billion dollar market.
  • 00:03:37
    the largest segment of the diet food industry.
  • 00:03:40
    But there was a catch.
  • 00:03:42
    When food manufacturers took out the fat
  • 00:03:44
    they had to replace it with something
  • 00:03:45
    that still made it taste good,
  • 00:03:47
    which almost always meant adding extra sugar
  • 00:03:49
    and carbohydrates.
  • 00:03:51
    Compared to the late '70s, today we eat
  • 00:03:53
    around 60 more pounds of grains
  • 00:03:55
    and 30 more pounds of sweeteners every year.
  • 00:03:58
    At the same time, we're eating
  • 00:03:59
    up to 400 more calories per day.
  • 00:04:02
    In recent years there are signs
  • 00:04:04
    that perspectives are changing.
  • 00:04:06
    In 2015 the official dietary guidelines eliminated
  • 00:04:09
    its limits on cholesterol.
  • 00:04:11
    And the American Heart Association
  • 00:04:12
    has gradually revised its guidelines
  • 00:04:14
    and moved away from its strict guidance to lower fat intake.
  • 00:04:18
    The bottom line is that nutrition is complex.
  • 00:04:21
    And despite collective efforts of some
  • 00:04:22
    of the planet's best minds the science
  • 00:04:24
    of nutrition is still young and evolving.
  • 00:04:27
    The number of annual studies on obesity
  • 00:04:29
    and diabetes alone has risen
  • 00:04:30
    from about 1,000 in 1960 to 44,000 in 2013.
  • 00:04:35
    It's likely that more than a million articles
  • 00:04:37
    have been published on dieting over the last 50 years.
  • 00:04:40
    Given all the complexity
  • 00:04:42
    perhaps the food pyramid's greatest mistake
  • 00:04:44
    was in its inception because an oversimplified,
  • 00:04:47
    one size fits all recommendation
  • 00:04:49
    is a pretty surefire recipe for getting things wrong.
