The impact of dietary fats and oils on health continues to be a controversial subject. In addition, the ability of the food industry to freely alter the fat content and composition of foods to meet dietary recommendations is limited by how these food components affect food quality and stability. Therefore, a recent workshop was held to bring together food and nutrition scientists to highlight nutritional research and product innovations that explore the nutritional impact of fatty acids in the food supply. The latest research on metabolic responses and health benefits associated with foods made with new nutritional and functional oils was discussed, along with a detailed look at how science-based advances in preparation methods and processing technologies affect the nutrient profile of food products, including potato products. Additional discussion was provided on how oil innovations align with dietary guidance and policy. This supplement issue presents articles on those presentations. Source

Studies have shown that higher than usual intakes of trans fatty acids (TFAs) have adverse effects on blood lipids. Because of this, in 2006 the US FDA mandated labeling of TFAs on food packages. The food and restaurant industries, including the potato industry, reformulated their foods to reduce or eliminate partially hydrogenated vegetable oils and TFAs. Before mandatory labeling, grain-based desserts, yeast breads, and French-fried potatoes (FFPs) were the top sources of TFAs in the food supply; by 2007, potato food manufacturers and quick-service restaurants had reduced or eliminated TFAs without increasing saturated fatty acids (SFAs). FFPs are no longer a source of TFAs in the food supply. This study examined energy and fatty acid intake among children aged 6-11 y, adolescents aged 12-18 y, and adults aged ≥19 y across 3 time periods by using data from the NHANES 2005-2006, 2007-2008, and 2009-2010. On average, intakes of total energy, total fat, SFAs, and monounsaturated fatty acids (MUFAs) decreased significantly between 2005-2006 and 2009-2010 among children and adolescents; however, the intake of polyunsaturated fatty acids (PUFAs) did not change. Among adults, intakes of total fat, SFAs, and MUFAs decreased; however, total energy and PUFA intake did not change. On the day of the 2009-2010 survey, ~13% of children and 10% of adolescents reported consuming fried FFPs, whereas <7% of adults reported consumption of fried FFPs. Intakes of SFAs and TFAs from fried FFPs decreased significantly between 2005-2006 and 2009-2010 among children, adolescents, and adults. This study confirms that intake of TFAs from FFPs is trivial. © 2015 American Society for Nutrition. Source

Vegetables, especially white potatoes, provide significant levels of key nutrients of concern, such as potassium and dietary fiber. Per capita availability (PCA) data for vegetables-often used as a proxy for vegetable consumption-show that vegetable consumption, including consumption of white potatoes, declined in the past decade. Using dietary data for participants in the NHANES 2009-2010, we examined total vegetable, white potato, and French-fried potato consumption among all age-gender groups as well as mean energy, potassium, and dietary fiber intakes. Mean total energy intake for the US population (≥2 y old) was 2080 kcal/d, with white potatoes and French-fried potatoes providing ~4% and ~2% of total energy, respectively. Individuals who consumed white potatoes had significantly higher total vegetable and potassium intakes than did nonconsumers. In addition, the proportion of potassium and dietary fiber contributed by white potatoes was higher than the proportion that they contributed to total energy. Among white potato consumers aged 14-18 y, white potatoes provided ~23% of dietary fiber and ~20% of potassium but only ~11% of total energy in the diet. The nutrient-dense white potato may be an effective way to increase total vegetable consumption and potassium and dietary fiber intake. Adv.

Grains, fruits, and vegetables are the primary sources of dietary fiber (DF), with the white potato contributing nearly 7% of the DF to the US food supply. The DF composition of the white potato-with or without the skin and regardless of cooking method-compares well with the DF content of other vegetables. Many health benefits, including improved gastrointestinal health, are attributed to greater DF consumption; however, less than 3% of males and females have an adequate intake of DF. Because of this population-wide shortfall, DF is considered to be a nutrient of concern. In this study, using data from the National Health and Nutrition Examination Survey 2009 to 2010, we examined the mean intake of DF across sex, age, race/ethnicity, family income, and poverty threshold. This study shows that mean intake of DF is far below recommendations, with children and adolescents aged 2 to 19 years consuming an average of less than 14 g of DF per day. Adults 20+ years old consume, on average, about 17 g of DF per day, and men consume significantly more DF than women. Non-Hispanic black adults consume significantly less DF compared with other race/ethnic groups. Lower family income and living at less than 131% of poverty were associated with lower DF intakes among adults. Federal and local government policies should encourage consumption of all vegetables, including the white potato, as an important source of DF. © 2014 The Authors. Source
