Excessive ultraprocessed foods (UPFs) and poor nutrition tied to poor health
New American Heart Association Science Advisory reviews current evidence about UPFs and their impact on adverse health outcomes
Ultraprocessed foods or UPFs are a growing concern due to their widespread consumption and impact on potential health risks. Most UPFs, particularly those commonly seen in U.S. dietary patterns, are high in saturated fat, added sugars and sodium (salt), the combination of which is often abbreviated as HFSS, and contribute to excess calories. These include sugar-sweetened drinks, ultraprocessed meats, refined grains, candy and commercial baked goods, among others. A limited number of ultraprocessed foods, such as certain commercial whole grains, low-fat-low-sugar dairy, and some plant-based items, have positive nutritional value and, therefore, can be part of an overall healthy dietary pattern. This overlap is confusing for health care professionals and the public.
A new Science Advisory from the American Heart Association, “Ultraprocessed Foods and Their Association with Cardiometabolic Health: Evidence, Gaps and Opportunities,” summarizes current knowledge about UPFs and their impact on cardiometabolic health, and outlines opportunities for research, policy and regulatory reform to improve dietary intake and overall health. The manuscript published today in Circulation, the flagship journal of the American Heart Association.
“The relationship between UPFs and health is complex and multifaceted,” said Maya K. Vadiveloo, Ph.D., R.D., FAHA, volunteer chair of the writing group for this Science Advisory. “We know that eating foods with too much saturated fat, added sugars and salt is unhealthy. What we don’t know is if certain ingredients or processing techniques make a food unhealthy above and beyond their poor nutritional composition. And if certain additives and processing steps used to make healthier food like commercial whole grain breads have any health impact.”
The rapid rise in UPF consumption since the 1990s disrupted traditional dietary patterns, potentially contributing to adverse health effects. It is estimated that 70% of grocery store products in the U.S. contain at least one ultraprocessed ingredient. As detailed in a CDC report published yesterday, 55% of calories consumed by people ages 1 and older in the U.S. were UPFs. Among youth ages 1-18 years of age, total UPF calories jumped to nearly 62%, and among adults ages 19 and older total UPF calories was 53%. In addition, families with lower mean income had a higher percentage of UPFs consumed per day: 54.7% for the lowest income group vs. 50.4% for highest income group.
UPFs are relatively inexpensive, convenient for use and aggressively marketed, particularly toward youth and under-resourced communities, often displacing healthier alternatives. This shift resulted in lowering the overall nutritional quality of typical eating patterns in the U.S. and is misaligned with the American Heart Association’s dietary guidance.
This new Science Advisory reinforces current dietary guidelines from the American Heart Association to:
- Reduce the intake of most UPFs, especially those high in saturated fat, added sugars and sodium, and those that contribute to excessive calories; and
- Replace UPF consumption with healthier options like vegetables, fruits, whole grains, beans, nuts, seeds and lean proteins.
