    Identifying institutional capacity to reduce and reallocate food waste is important to reduce both greenhouse gas emissions and food insecurity. The goal of this study was to examine food waste concern, reduction and repurposing strategies, and perceived barriers to these strategies among U.S. university foodservice representatives. We surveyed 57 U.S. university foodservice representatives about foodservice operations, campus food insecurity, food waste reduction and repurposing activities, and obstacles to composting and donating food waste. Data were collected September 2019–February 2020. Roughly three-quarters of respondents tracked campus food waste, reported that food waste reduction was a high/very high priority, and reported concern about campus food insecurity. The most common food-waste-reduction strategies included forecasting demand to prevent overproduction and preparing smaller batches. The most common repurposing strategies included donation and composting. Top barriers to food donation included liability concerns and lack of labor. Barriers to composting food included lack of infrastructure and knowledge/experience. Addressing perceived barriers to university foodservices’ food waste reduction and repurposing efforts could lead to reduced greenhouse gas emissions and improved food security for millions of Americans

    Effects of an educational planetary plate graphic on meat consumption in a Stanford University dining hall: a randomized controlled trial

    Abstract Background Assess the impact of an educational Planetary Health Plate (PHP) graphic on meat-related dietary choices of Stanford University dining hall patrons using a randomized controlled trial crossover design. All patrons entering the dining hall during study periods were enrolled as participants. Control, n = 631; PHP, n = 547. Methods Compare dietary behavior without signage to behavior while exposed to PHP during four equivalent dinner meals. The primary outcome was total meat-dish weight adjusted for the number of people entering the dining hall. Secondary outcomes included the number of meat-dish servings and average meat-dish serving weight. Analysis using T-tests, Poisson generalized linear model. Results Differences in total meat-dish weight, (1.54 kg; 95% Confidence Interval [CI] = -4.41,1.33; P = .19) and average meat-dish serving weight (0.03 kg; 95% CI = 0.00, 0.06; P = .07) between PHP and control patrons did not reach significance. The rate at which PHP patrons took meat was significantly lower (Incidence Rate Ratio 0.80; 95% CI = 0.71, 0.91; P < .001). Conclusion Exposure to an educational plate graphic decreased the proportion of patrons taking meat but had no impact on total meat consumption or meat-dish serving weight. Statistical methods used in this study may inform future investigations on dietary change in the dining hall setting. Further research on the role of educational signage in influencing dietary behavior is warranted, with an aim to improve human health and environmental sustainability.

    Smart Home is one of the tools that is developed for ease of automation of smart home management from the start of address, security, comfort, savings, through automation with Android. In designing a micro home security system controller using raspberry pi 3 and Android smartphones that can reduce the number of criminal acts of burglary door. This tool consists of an electro magnetic door lock called a solenoid door lock.This solenoid key is placed on the door of the house for security. The design of this home door security system utilizes Raspberyy pi b + as a control device from near and far by utilizing the wifi network and sms gateway to control opening and closing the home door lock that is controlled via an android mobile. Through web bootstrap that will display the results captured by the camera to provide a home situation every time someone enters.This house door security system that has been successfully built and tested with the working principle if there is someone who forces or breaks the house door in a closed condition, the system will activate a warning or alarm by sounding the buzzer¸ because there is an LDR sensor connected to one switch connected to the solenoid key that results, if the key is opened with a security system then the LDR sensor will turn off and there will be no alarm, but if it is forced to break the LDR sensor will activate and read the movement of the door so that the reaction occurs and the buzzer alarm will sound. This security system is a solution to increase the level of home security ¸ besides this sophisticated system is very easy to use and integrated with android smartphone

    Les CLA peuvent-ils prévenir l’athérogenèse ?

    The anti-atherogenic properties of CLA are now illustrated in many animal studies (Rabbit, Mice and Hamster) or cell culture experiments. These properties can be observed while using either the CLA isomeric mixture (cis9,trans11- and trans10,cis12-, 50 :50) or selected CLA isomers (cis9,trans11- or trans10,cis12-). Especially, these fatty acids consistently attenuate the outcome of primary vascular lesions (fatty streaks), or can even induce a regression of pre-established lesions. There is, paradoxically, no clear relationship between this beneficial effect and an improvement of the lipid status in blood (triglycerides, total cholesterol, LDL-cholesterol, HDL-cholesterol) usually considered as a hallmark in the etiology of atherosclerosis. On the other hand, recent data obtained both in vitro and in vivo indicate that part of the beneficial effects of CLA occurs through the modulation of vascular inflammatory and oxidant stress factors (cytokines and cyclooxygenase), as well as from the expression of adhesion molecules (VCAM, ICAM) in the aorta. This regulation involves the interaction of CLA with transcription factors such as PPARs, LXR and NF-kB targeting the gene expression dowstream. In human, clinical trials are no more conclusive than the animal experiments with regards to the contribution of CLA to modulate the lipid status in blood. Nevertheless, some data highlight the pro-atherogenic role of CLA and especially of the trans10,cis12-isomer, as demonstrated by the increase in the various markers of oxidative stress (isoprostanes) and inflammatory status (C-reactive protein). In conclusion, whereas there is compelling evidence that feeding mixed or pure isomers of CLA attenuates atherosclerosis initiation and progression in several experimental models, human studies are less convincing. Nevertheless, clinical trials addressing sufficient risk factors and risk markers together are still lacking to draw a definitive conclusion and to set up obvious recommandations. The use of the sole blood lipids do not seem to be appropriate for such an evaluation

    Food Choice and Waste in University Dining Commons-A Menus of Change University Research Collaborative Study.

    The purpose of this multi-campus research was to investigate the relationships of food type and personal factors with food choice, consumption, and waste behaviors of college students at all-you-care-to-eat dining facilities. The amount of food taken and wasted was indirectly measured in units relative to the plate size using before and after photos taken by the diners themselves. Animal protein and mixed dishes (e.g., stir fry, sandwich) took up more of diners' plate space and these items were correlated to both greater hedonic appeal as well as a higher likelihood of the item being pre-plated. Greater confidence in liking an item before choosing it was correlated to a larger portion being taken. Finally, increased satisfaction with the meal and frequency of visiting the dining commons was correlated to less food waste. Understanding these potential food choice drivers can help dining facilities better target healthier meals to diners while reducing food waste
