Potatoes are the largest and most affordable source of potassium of any vegetable or fruit

27.09.2011
Potato consumption leads to higher overall diet quality

A frequently expressed concern in the ongoing public health debate is that fresh fruits and vegetables, particularly those that are nutrient dense, are not affordable to the average consumer. Research presented today at the American Dietetic Association's (ADA) Food and Nutrition Conference and Expo (FNCE) demonstrates that potatoes are one of the best nutritional values in the produce department, providing significantly better nutritional value per dollar than most other raw vegetables. Per serving, white potatoes were the largest and most affordable source of potassium of any vegetable or fruit.

Dr. Adam Drewnowski and colleagues from the University of Washington merged nutrient composition data from the USDA Food and Nutrition Database for Dietary Studies (FNDDS 2.0) with the USDA Center for Nutrition Policy and Promotion (CNPP) national food prices database. Frequency of consumption data was obtained from the National Health and Nutrition Examination Survey (NHANES 2003-4). The Affordable Nutrition Index (ANI) was the metric used to assess nutritional value per dollar for potatoes and for other vegetables.

Potatoes were the lowest cost source of dietary potassium, a nutrient identified by the 2010 Dietary Guidelines as lacking in the American diet. The high cost of meeting federal dietary guidelines for potassium, 4,700 mg per person per day, presents a challenge for consumers and health professionals, alike. However, the cost of potassium-rich white potatoes was half that of most other vegetables.

"Potatoes deserve credit for contributing to higher diet quality and increasing vegetable consumption," said lead researcher Adam Drewnowski, PhD. "Potatoes also play an important role in providing affordable nutrition to Americans. You CAN afford to meet key dietary guidelines IF you include potatoes in your diet."

Further analyses of NHANES dietary intake showed that putting potatoes on the plate did improve overall diet quality. Individuals who consumed potatoes (baked, boiled and roasted) had higher intakes of potassium and vitamin C and consumed more total vegetables in a day compared to those who did not consume potatoes.

The study was funded by the United States Potato Board and adds to the growing database of nutrition science that supports potatoes in a healthful diet. In addition, one medium-size (5.3 ounce) skin-on potato contains just 110 calories per serving, boasts more potassium (620g) than a banana, provides almost half the daily value of vitamin C (45 percent), and contains no fat, sodium or cholesterol.

About the United States Potato Board

The United States Potato Board was established in 1971 by a group of potato growers to promote the benefits of eating potatoes. Recognized as an innovator in the produce marketing industry, the USPB adopted a new campaign in 2007. "Potatoes… Goodness Unearthed®" showcases the appeal of naturally nutrient-rich potatoes, also known as America's favorite vegetable. Based in Denver, Colo., the USPB represents more than 4,000 potato growers and handlers across the country. To unearth more goodness about the USPB and its programs, visit www.potatogoodness.com

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
