NCA Update: 2020 US Dietary Guidelines Scientific Review

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.

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.

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.

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.
