Updated study shows baseline annual diet costs less for women than men
A recent study updated the classic 'Stigler's Diet Problem' to reflect current dietary recommendations and prices. The results show that a woman's diet is approximately $115.40 cheaper than a man's, with daily costs of $535.27 for women and $651.27 for men.
Monkeys pay one another for work
Capuchin monkeys have been found to cooperate in obtaining food by working together and sharing the rewards. This study by Frans de Waal and Michelle Berger suggests that reciprocity is a fundamental feature of human society and has implications for understanding evolutionary cooperation.
Purdue researcher creates soy feed to keep fish on the table
A Purdue University researcher has developed a soy-based feed for farm-raised fish, reducing phosphorus and nitrogen excretion and minimizing pollution. This alternative feed is expected to meet growing demand in the aquaculture industry, which is struggling with declining wild fish populations.
Food web theory suggests ecology may be governed by general rules
Scientists developed a theoretical model of food web organization based on two simple rules, revealing deep similarities between diverse ecosystems. The 'niche model' accurately predicts 12 characteristics of food webs, surpassing the cascade model's predictions.
Saturated fats: The very bad,the not-so-bad and the benign
Researchers Hu et al. found little distinction among saturated fatty acids on cardiovascular risk, and combining with less harmful ones in food sources reduced risk significantly when replaced by monounsaturated and polyunsaturated fats.
Vegans likely short on calcium, experts say
A study by Purdue University found that vegan diets lack sufficient calcium, even with dairy-free alternatives. Experts recommend drinking milk or adding fortified foods/supplements to meet the daily calcium requirement. Vegans may need to consume large amounts of calcium-rich vegetables like broccoli and kale to get enough.
IFT '99: Prophetic Window To The World Of Food
The Institute of Food Technologists' 1999 Annual Meeting & FOOD EXPO will feature over 1,200 scientific presentations on global food safety, nutraceuticals, biotechnology, and more. Attendees can also explore the latest in food products, ingredients, and processing techniques.
IFT And NRA To Co-Host Food Safety Forum For Restaurateurs And Food Retailers
Representatives from IFT, FDA, and industry experts will discuss cooking and food storage time and temperature specifications in restaurants and retail food operations. The forum aims to enhance food safety and quality worldwide through information exchange and knowledge sharing among members.
Testing Restaurant Compost For Greenhouses
A recycling plan devised by Cornell University students aims to save restaurant scraps from landfills and send them to compost piles, boosting community greenhouse-gardens. Seven restaurants have expressed interest in composting their food scraps, and a pilot study is underway.
Restaurant Meats Higher In Suspected Carcinogens
A study by government scientists found restaurant-prepared meats contain cancer-causing compounds up to ten times higher than similar fast food items. Heterocyclic amines, formed during cooking, are believed to contribute to cancer in people.
Free Program On The World Wide Web Lets Users Analyze What They Eat
The Nutrition Analysis Tool (NAT) allows users to analyze the nutrients in over 5,200 common food items based on daily allowance data from the US Department of Agriculture. Researchers are working to add an energy calculator to help high school athletes at risk for anorexia and bulimia make better nutrition decisions.
Bottom-up Ecological Processes Better For Clear Waters, Study Finds
Researchers at UC Davis analyzed eight lake studies and found that limiting nutrient supply is a stronger mechanism for controlling algae blooms than tinkering with food webs. This challenges the 'trophic cascade hypothesis,' which suggests manipulating food web structure can regulate lake clarity.
New Sensor Provides First Instant Test For Toxic E. coli Organism
A new sensor developed by Berkeley Lab can detect the presence of toxic E. coli bacteria instantly, providing a cost-effective solution for food companies, health inspectors, and consumers. The sensor uses a color-changing technology that can be placed on various materials, allowing for rapid detection of contaminated products.
Researchers Close In On Source Of Peanut Allergy
Scientists have narrowed down the list of suspect peanut proteins from 30 to seven, a significant step towards developing effective treatments for peanut allergies. The identification of these specific proteins opens up new avenues for investigation, including gene injection therapy and vaccine development.
