Added fructose in particular (eg, as a constituent of added sucrose or as the main component of high-fructose sweeteners) may pose the greatest problem for incident diabetes, diabetesrelated metabolic abnormalities, and CV risk. Conversely, whole foods that contain fructose (eg, fruits and vegetables) pose no problem for health and are likely protective against diabetes and adverse CV outcomes. Several dietary guidelines appropriately recommend consuming whole foods over foods with added sugars, but some (eg, recommendations from the American Diabetes Association) do not recommend restricting fructose-containing added sugars to any specific level. Other guidelines (such as from the Institute of Medicine) allow up to 25% of calories as fructose-containing added sugars. Intake of added fructose at such high levels would undoubtedly worsen rates of diabetes and its complications. There is no need for added fructose or any added sugars in the diet; reducing intake to 5% of total calories (the level now suggested by the World Health Organization) has been shown to improve glucose tolerance in humans and decrease the prevalence of diabetes and the metabolic derangements that often precede and accompany it. Reducing the intake of added sugars could translate to reduced diabetes-related morbidity and premature mortality for populations.

Prevailing thinking about obesity and related diseases holds that quantifying calories should be ... more Prevailing thinking about obesity and related diseases holds that quantifying calories should be a principal concern and target for intervention. Part of this thinking is that consumed calories - regardless of their sources - are equivalent; i.e. 'a calorie is a calorie'. The present commentary discusses various problems with the idea that 'a calorie is a calorie' and with a primarily quantitative focus on food calories. Instead, the authors argue for a greater qualitative focus on the sources of calories consumed (i.e. a greater focus on types of foods) and on the metabolic changes that result from consuming foods of different types. In particular, the authors consider how calorie-focused thinking is inherently biased against high-fat foods, many of which may be protective against obesity and related diseases, and supportive of starchy and sugary replacements, which are likely detrimental. Shifting the focus to qualitative food distinctions, a central argument of th...

We take the issue with several points made by the authors and make a case for quite different conclusions. The authors state that, “salt is a major drive to thirst”; “an increase in salt intake will increase the amount of fluid consumed, and if part of this fluid is in the form of soft drinks, [sugar] will be increased proportionately.” In other words, salt consumption drives fluid intake, and sugar may just, coincidentally, come along for the ride. We would argue something more akin to the opposite. Sugar consumption leads to insulin spikes, low blood sugar, and hunger. Sugar is a major drive to hunger; an increase in sugar will increase the amount of food consumed, and if part of this food is in the form of processed foods, sodium will be increased proportionately. In other words, sugar consumption drives food intake, and sodium may just, coincidentally, come along for the ride. Processed foods are the principal source of dietary sodium2; they also happen to be predominant sources of added sugars. Dietary sodium intake tracks with the consumption of added sugars, but it is that sugar, not the salt, that may be the actual causative factor for increased blood pressure ...

Methods A telephone survey of 4,399 residents of Philadelphia, Pennsylvania, provided data on individuals, their households, their neighborhoods (self-defined), their food-environment perceptions, and their fruit-and-vegetable consumption. Other data on neighborhoods (census tracts) or "extended neighborhoods" (census tracts plus 1-quarter-mile buffers) came from the US Census Bureau, the Philadelphia Police Department, the Southeastern Pennsylvania Transportation Authority, and the federal Supplemental Nutrition Assistance Program. Mixed-effects multilevel logistic regression models examined associations between food-environment perceptions, fruit-and-vegetable consumption, and individual, household, and neighborhood characteristics. Results Perceptions of neighborhood food environments (supermarket accessibility, produce availability, and grocery quality) were strongly associated with each other but not consistently or significantly associated with objective neighborhood measures or self-reported fruit-and-vegetable consumption. We found racial and educational disparities in fruitand-vegetable consumption, even after adjusting for food-environment perceptions and individual, household, and neighborhood characteristics. Having a supermarket in the extended neighborhood was associated with better perceived supermarket access (adjusted odds ratio for having a conventional supermarket, 2.04 [95% CI, 1.68-2.46]; adjusted odds ratio for having a limited-assortment supermarket, 1.28 [95% CI, 1.02-1.59]) but not increased fruitand-vegetable consumption. Models showed some counterintuitive associations with neighborhood crime and public transportation. Conclusion We found limited association between objective and self-reported neighborhood measures. Sociodemographic differences in individual fruit-and-vegetable consumption were evident regardless of neighborhood environment. Adding supermarkets to urban neighborhoods might improve residents' perceptions of supermarket accessibility but might not increase their fruit-and-vegetable consumption. Several studies on fruit-and-vegetable intake have examined individual and neighborhood characteristics simultaneously using multilevel models (5-13). Few of these studies, however, have considered both objective and self-reported measures of food environments (6-9). Those that have generally have not given attention to some potentially relevant individual characteristics (eg, overall health status, body mass index [BMI]), and none have considered broader neighborhood issues (eg, public transportation, neighborhood crime). Our study builds on prior research, considering and adjusting for several relevant individual, household, and neighborhood factors, to assess 1) how individuals' self-reported perceptions compare with objective measures of neighborhood environments, and 2) how self-reported and objective neighborhood measures each relate to reported fruit-and-vegetable consumption. Methods The University of Pennsylvania institutional review board approved this study. Survey data on individuals Data on individuals came from Public Health Management Corporation's biennial random-digit-dialed Southeastern Pennsylvania Household Health (SPHH) survey (www.chdbdata.org/householdsurvey.html). The 2010 survey, administered from June through October, included 4,399 adult respondents from Philadelphia's 379 census tracts. Service-area stratification helped ensure sufficient representation of sociodemographic subpopulations. Response rates were 25.5% for landlines and 20.6% for cellular telephones, comparable to rates from similar large community health surveys (14). Dependent variables in multilevel models Depending on the regression model, the dependent variable was either individuals' reported fruit-and-vegetable consumption or one of 3 perceptions of the neighborhood food environment. Fruit-and-vegetable consumption was measured by a single item: "How many servings of fruits and vegetables do you eat on a typical day? A serving of a fruit or vegetable is equal to a medium apple, half a cup of peas or half a large banana." Response options were open-ended (any nonnegative integer). Perceptions of the neighborhood food environment related to 1) supermarket accessibility ("Do you HAVE to travel outside of your neighborhood to go to a supermarket?" [yes, no]), 2) grocery quality ("How would you rate the overall quality of groceries available in the stores in your neighborhood?" [excellent, good, fair, poor, absent]), and 3) produce availability ("How easy or difficult is it for you to find fruits and vegetables in your neighborhood?" [very easy, easy, difficult, very difficult]). Self-reported independent variables and covariates The dependent variables also served as predictors in models for which they were not the outcomes. Studies show associations among these variables (4,6,12,15,16) and between these variables and modeling covariates. Modeling covariates included characteristics of individuals (age, sex, race/ethnicity, nativity [whether or not born in the United

Little is known about how the distribution of food deserts and food swamps relate to disparities in self-reported dietary habits, and health status, particularly for historically marginalized groups. In a national U.S. sample of 4305 online survey participants (age 18+), multinomial logistic regression analyses were used to assess by race and ethnicity the likelihood of living in a food swamp or food desert area. Predicted probabilities of self-reported dietary habits, health status, and weight status were calculated using the fitted values from ordinal or multinomial logistic regression models adjusted for relevant covariates. Results showed that non-Hispanic, Black participants (N = 954) were most likely to report living in a food swamp. In the full and White subsamples (N = 2912), the perception of residing in a food swamp/desert was associated with less-hea...

The 2 doctors suggest there is a lack of sound evidence that low-sodium diets increase hospitalizations and mortality versus normal-sodium diets because the trials cited in our review used unusual diuretic dosing. Specifically, Hummel and Weder are concerned about high doses of furosemide not commonly used in the United States or Europe. However, in the largest randomized trial we cite (n ¼ 1771), investigators gave furosemide at a dose of 50 mg twice daily (ie, 100 mg/d) to approximately two thirds of all enrolled patients. 3 This dose is well within doses commonly used in Western clinical practice, and the adverse outcomes seen in the trial despite such reasonable therapy raise concern about the safety of concomitant sodium restriction. Hummel and Weder also suggest, without citing any literature specifically, that there are "abundant data.that at least some persons would greatly benefit from dietary sodium restriction." We assume that the physicians are referring to trials reporting "benefit" with regard to the selective surrogate outcome of blood pressure (ignoring adverse effects for other surrogate outcomes 4). However, improvements in any surrogate outcomes do not necessarily translate to improvements in patient-oriented outcomes that matter most (ie, morbidity and mortality). As a number of studies have shown, severe sodium restriction may adversely affect patient-oriented outcomes. 5-8 Last, Hummel and Weder note that, contrary to our arguments, it is indeed "possible" to restrict sodium intake in a meaningful way in the general population. Although some degree of sodium restriction may be possible in the shortterm, whether human physiology will allow maintenance of meaningful restrictions in the long-term is a matter of some debate. Human sodium intake occurs in a remarkably narrow range across diverse populations, eating habits, and time. 9 Regardless, even if long-term population-wide sodium restriction was possible, we are most concerned about the wisdom and safety of such action. The evidence for benefit is lacking, and we agree with Hummel and Weder that "additional research.is needed." Until the findings of such research are available though, we maintain that it is premature to support attempts to markedly reduce sodium intake among the general population.

The extent of such advertising on mass transit has not been reported. We sought to characterize all print advertising in Bronx subway stations and consider potential implications of ad content and placement for surrounding communities. METHODS: Researchers rode all Bronx subway lines, assessing all ads in all stations. Data about surrounding neighborhoods (census tracts) came from the U.S. Census and city health department. Data on subway ridership came from the city transit authority. RESULTS: Across all 68 subway stations there were 1,588 print ads. Each subway station had 0-106 ads (or up to 226 ads counting duplicates). Ads were for 146 brands/organizations, 11 of which (7.4%) were unhealthy-food/beverage brands (e.g., candy, ice-cream, sugary-beverage, snack-chip, fast-food, alcohol). The amount of total ad exposure (number of ads x size of each) was directly correlated with station ridership, but the proportion of unhealthy-foods/beverage-ad exposure was inversely correlated with ridership (suggesting targeted marketing, not marketing to the widest audience). Unhealthy-food/beverage ads disproportionately featured children (p<0.01), were in languages other than English (p=0.002), and appeared in neighborhoods with lower high-school graduation rates (p=0.03)--and although not quite reaching statistical significance, neighborhoods with more poverty (p=0.057), higher mean sugar-sweetened-beverage consumption (p=0.053), and higher mean blood pressure and cholesterol levels (p=0.053). DISCUSSION: Unhealthy-food/beverage ads were more likely to be in neighborhoods with greater socioeconomic challenges and possibly diet and diet-related-health challenges, with most ads geared toward youth in high-immigrant areas. Ad content and placement suggested targeted marketing to vulnerable groups.

Sugar would have been a rare source of energy in the environment, and strong cravings for it would have benefitted human survival. Sugar cravings would have prompted searches for sweet foods, the kind that help us layer on fat and store energy for times of scarcity.

(http://bit.ly/1jrrARV) I have already congratulated the lead and senior authors on their piece. But I have also shared my concerns with them about their work. I would like to share my concerns more broadly here. ABFM Performance in Practice Modules (PPMs) have the laudable aim of improving quality for patient care. Diabetes care was the focus of the PPM in this article. The article describes using measures from the National Quality Forum (NQF) for its benchmarks, and the article&#39;s authors confirm to me that NQF did indeed set their targets. Among the targets were one-size-fits-all hemoglobin A1c goal of &lt;7% and blood-pressure goal of &lt;130/90 mm Hg. These goals are concerning.

Street vendors were encouraged to sell fresh fruits and vegetables. Objective: Esperanza del Barrio developed an online map (locarto.org) that street vendors could update and shoppers could access using cell phone text messages. Methods: Programmed in xhtml, Locarto allows vendors to register online, and thereafter send a text message with their address to a central number to update their location on the publicly available map. Community members can use the online map, or send a text message with their address to the central number, and receive a response with the nearest vendors. The model tests the utility of a text message-based map for low-literacy and low-technology populations, by tracking both the number of vendors enrolled and the number of consumers served. The map was promoted through public, community, and academic collaborators. Results: This presentation will focus on the number of vendors and consumers utilizing the site (since launch and per month), and their geographic distribution. Conclusions: This is a novel method of real-time tracking and promotion of healthy food availability in underserved neighborhoods. Collection of initial utilization data will pave the way for future dissemination and evaluation.
