NCA Update: 2020 US Dietary Guidelines Scientific Review

/ nationalcoffee / Leave a comment

Setting the stage for the next evolution in dietary guidance to Americans for 2020-2025

Editor’s note: The connection between lifestyle and health is increasingly being recognized by the medical and scientific communities. We know that diet, exercise habits, and smoking and alcohol consumption impact our health. And as the science continues to advance, it seems there are new discoveries weekly.

To help Americans make healthy food and beverage choices, the U.S. Government issues Dietary Guidelines, which in the past have been communicated by USDA guides such as the Food Guide Pyramid and MyPlate.

When the USDA last undertook this exercise, the NCA formally recommended that the healthy aspects of coffee be recognized – and they were.  The 2015-2020 Guidelines acknowledge that coffee can be part of a healthy diet.

And the process to update these guidelines is now well underway.

By Dr. Mark Corey, Director of Scientific & Government Affairs, National Coffee Association

Over the past two days, I attended the meeting of the 2020-2025 Dietary Guidelines Advisory Committee (DGAC) in Washington, DC, focused on creating the protocol and guidelines shaping US nutrition and guidance to Americans for the next 5 years.

Panels of experts are examining every aspect of the American diet, inside and out, and have outlined their process for evaluating the science-based evidence. Subcommittees are focused on a range of topics such as dietary patterns and looking across different age groups from birth to older adults.

The science behind increasing global demand

By Bill (William) Murray, President & CEO, National Coffee Association

I’ve been thinking about the good news, challenges, and opportunities that face all of us in the coffee community – just as I travel to Brazil for the upcoming World Coffee Producers Forum. 

The good news should be well known to all:  last month California finally gave coffee the all clear, joining scientists worldwide in concluding that coffee does not cause cancer and may in fact protect against cancer and other diseases.

California has moved to correct a confusing contradiction on coffee and health.

It’s a great moment for the coffee industry and the billions of people around the world who enjoy their cup of joe every day.

In serving up the perfect blend of science and regulation, the State of California has moved to formally recognize that coffee should not carry a “cancer warning.”

What might seem like a “duh” moment to most scientists and coffee drinkers alike was actually years in the making.

Pot Head: The Coffee Cannabis Connection

Coffee is a complex substance and — as a new study finds — its metabolic interactions are equally complex.

Coffee influences the same regions of the brain as cannabis, according to recent research.

Although studies looking at coffee’s health benefits — or lack thereof — appear to be published on an almost daily basis, its true impact on health is still poorly understood.

Some studies have found health benefits, some have concluded that it might reduce mortality risk, and others drew no solid conclusions.

This confusion is due to several factors, and one is the difficulty in separating cause and effect in large, population-based studies. For example, someone who drinks a lot of coffee might also sleep less, smoke more tobacco, drink less water, or work unsociable hours. These factors muddy the statistical waters.

Also, coffee is an incredibly complex beast; it contains more than 1,000 aroma compounds, levels of which vary depending on the type of coffee bean and how it is brewed.

Researchers from Northwestern University in Chicago, IL, took a detailed look at the impact of coffee consumption on our internal chemistry. Their findings were published this week in the Journal of Internal Medicine.

The scientists found that with increased coffee consumption, blood metabolites involved in the endocannabinoid system dropped off. This is the system that gives cannabis its recreational and medical effects.

What the Science Says About Common Coffee and Health Myths

Study after study has found that coffee has a host of potential health benefits. Yet there’s still a lot of confusion among consumers and in the media. 

Surprisingly, 69% of Americans report that they have not even heard of any studies related to coffee and disease prevention, according to recent NCA market research.

And despite the fact that people already have less than the 3-5 cups daily recommended for optimal physical benefit, limiting caffeine intake was cited as the leading reason to cut coffee consumption.

Here’s a quick glance at some of the most common misconceptions on coffee and health – and what the science really says.

What the Research Really Shows on Coffee & Cancer

Coffee may lower the risk of several types of cancer, according to recent studies reviewed by researchers at the American Cancer Society.

The following excerpt was originally posted at the American Cancer Society. 

AICR has named February Cancer Month. Learn more. 

To learn more about science, coffee, and why the research matters, join the experts from the NCA Scientific Leadership Council for “The Coffee Science Fair: A Fun Look at a Serious Topic,” a special educational session at the NCA 2019 Convention in Atlanta, GA on March 8.

Scientists have been investigating the links between coffee and cancer for decades. And while our understanding of coffee’s potential health benefits has improved with advances in research, there’s still more to learn.

In 2016, an expert panel convened by the International Agency for Research on Cancer (IARC) — the arm of the World Health Organization that is responsible for assessing whether certain substances cause cancer — could not conclude that drinking coffee is carcinogenic based on the current evidence available.

Yet the coffee-cancer connection has recently reappeared in the news, due to the ongoing Prop 65 legislation in California to put misleading “cancer warning labels” on coffee.

So, what do coffee drinkers need to know?

In following interview written by Elizabeth Mendes, American Cancer Society researchers Susan Gapstur, PhD, and Marjorie McCullough, ScD, explain what the studies really show when it comes to coffee and cancer, and discuss what other research is still needed.

Coffee and Cigarettes: Misinformation By Algorithm

Despite overwhelming scientific evidence, popular myths on coffee and health continue to persist.

By Kyra Auffermann, NCA Digital Content & Communications Manager

Coffee plays an important role in the lives (or at least mornings) of most people — in the United States, nearly 80% of all adults drink coffee, typically at the start of their day.

Yet most coffee drinkers don’t have a good understanding of coffee: the plant, the way it is processed, or the precision of a “perfect” roast.

In fact, more coffee drinkers may have a good misunderstanding of coffee. And despite overwhelming evidence, myths persist — particularly when it comes to coffee and health.
