All Sweet Potatoes Are Not Equal

22.02.2011
Although all varieties of sweet potatoes are nutritious, those that are orange may be the best source for vitamin A.

An article in the February 2011 issue of Comprehensive Reviews in Food Science and Food Safety (CRFSFS) discussed how orange sweet potatoes could help prevent vitamin A deficiency in developing countries where this nutritional disease causes over 600,000 deaths per year--mostly of young children or pregnant women.

Most sweet potatoes in the United States are orange, but in developing countries sweet potatoes can also be white, cream, yellow and purple. According to the author, Betty J. Burri, of Western Human Nutrition Center at the United States Department of Agriculture, in these countries where vitamin A deficiency is common, it would help if the food industry could find ways to increase the production and consumption of orange-fleshed sweet potatoes.

Specifically, food companies could further this goal by developing improved varieties of prolific, hardy, disease and drought-resistant orange-fleshed sweet potatoes while developing and testing different food products made from sweet potatoes. For example, one of the sweet potato products that international programs are testing is sweet potato flour, which they can make into biscuits and buns.

There are many good sources of vitamin A and pro-vitamin A carotenoids in the American diet as well as access to orange sweet potatoes. However, in some parts of Africa the custom is to feed orange sweet potatoes to livestock and white sweet potatoes (which have very little pro-vitamin A carotenoids) to people. There are ongoing educational programs to guide these populations to eat more orange sweet potatoes and improve their vitamin A status. The food industry could help educate people about the types of sweet potatoes that are available, their nutrient content, and the best methods for storing, preparing, and cooking them.

About IFT
The Institute of Food Technologists (IFT) is a nonprofit scientific society. Our individual members are professionals engaged in food science, food technology, and related professions in industry, academia, and government. IFT’s mission is to advance the science of food, and our long-range vision is to ensure a safe and abundant food supply, contributing to healthier people everywhere.

For more than 70 years, the IFT has been unlocking the potential of the food science community by creating a dynamic global forum where members from more than 100 countries can share, learn, and grow. We champion the use of sound science across the food value chain through the exchange of knowledge, by providing education, and by furthering the advancement of the profession. IFT has offices in Chicago, Illinois and Washington, D.C. For more information, please visit ift.org.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
