Veg ‘nudge’: an extra vegetarian option cuts meat consumption without denting food sales

A study of over 94,000 cafeteria meal choices has found that doubling the vegetarian options – from one in four to two in four – reduced the proportion of meat-rich purchases by between 40-80% without affecting overall food sales. The…

Common nutrient supplementation may hold the answers to combatting Alzheimer’s disease

In a new study, Biodesign researchers reveal that a lifelong dietary regimen of choline holds the potential to prevent Alzheimer’s disease (AD). Choline is a safe and easy-to-administer nutrient that is naturally present in some foods and can be used…

Test for life-threatening nutrient deficit is made from bacteria entrails

In a remote village, an aid worker pricks a sickly toddler’s fingertip, and like most of the other children’s blood samples, this one turns a test strip yellow. That’s how an experimental malnutrition test made with bacterial innards could work…

Micronutrients ‘slipping through the hands’ of malnourished people

Millions of people across the globe are suffering from malnutrition despite some of the most nutritious fish species in the world being caught near their homes, according to new research published in Nature today. Scientists from the ARC Centre of…

Pregnant women with obesity may not require additional calories for healthy pregnancies

The Institute of Medicine’s guidelines currently advise all pregnant women to increase calorie intake by 340-450 calories/day during their second and third trimesters, regardless of their body size at conception. Approximately 2/3 of women with obesity at the time of…

Kleinberg secures $2.3 million to develop AI patients can use to manage their health

With Kleinberg’s three new grants, she now has a total in $5.4 million for her research initiatives, which focus on useable artificial intelligence: information individual patients are able to use according to their lifestyle, beliefs and assumptions

Harnessing tomato jumping genes could help speed-breed drought-resistant crops

Researchers from the University of Cambridge’s Sainsbury Laboratory (SLCU) and Department of Plant Sciences have discovered that drought stress triggers the activity of a family of jumping genes (Rider retrotransposons) previously known to contribute to fruit shape and colour in…

Humans more unique than expected when it comes to digesting fatty meals

DAVIS, CALIFORNIA, September 12, 2019–People have very individualized inflammatory responses to eating a high-fat meal. These were the somewhat unexpected results of a study recently published in the Journal of Nutritional Biochemistry by researchers at the Agricultural Research Service (ARS)…

New study tracks sulfur-based metabolism in the open ocean

One of the planet’s most active ecosystems is one most people rarely encounter and scientists are only starting to explore. The open ocean contains tiny organisms — phytoplankton — that perform half the photosynthesis on Earth, helping generate oxygen for…

Brain circuit connects feeding and mood in response to stress

Many people have experienced stressful situations that trigger a particular mood and also change certain feelings toward food. An international team led by researchers at Baylor College of Medicine looked into the possibility of crosstalk between eating and mood and…

Corals take control of nitrogen recycling

Corals are shown to recycle their own waste ammonium using a surprising source of glucose–a finding that reveals more about the relationship between corals and their symbiotic algae. Symbiosis between corals and algae provides the backbone for building coral reefs,…

Skin cancer risk in athletes: The dangers of ultraviolet radiation

The dangers of ultraviolet radiation exposure, which most often comes from the sun, are well-known. Speaking at The Physiological Society’s Extreme Environmental Physiology conference next week, W. Larry Kenney, Penn State University, will discuss how broad its effects can be,…

Researchers determine pollen abundance and diversity in pollinator-dependent crops

CORVALLIS, Ore. – A new study provides valuable insights into pollen abundance and diversity available to honeybee colonies employed in five major pollinator-dependent crops in Oregon and California, including California’s massive almond industry. The study, a collaboration between OSU and…

Grassland biodiversity is blowing in the wind

Temperate grasslands are the most endangered but least protected ecosystems on Earth. Grassland restorations are crucial for recovering this important but highly degraded ecosystem. Restored grasslands, however, tend to be more species poor and lose diversity through time as compared…
