Discovery can assist farming of low-fertility crops, say UC Riverside biochemists Biochemists at the University of California, Riverside report a new role for vitamin C in plants: promoting the production of twins and even triplets in plant seeds. Daniel R. Gallie, a professor of biochemistry, and Zhong Chen, an associate research biochemist in the Department of Biochemistry, found that increasing the level of dehydroascorbate reductase (DHAR), a naturally occurring enzyme that recycles...

(Ivanhoe Newswire) -- In 2008, 39 million people in the U.S. were 65 or older. How much longer will they live? A new study could help them tack on a few more years! It suggests that a specific combination of supplements can reduce the rate of mortality in seniors, therefore providing a possible means of increasing life expectancy. The study assessed mortality among patients randomized to either vitamin D alone or vitamin D with calcium. In this study, researchers used pooled data from...

Children are more likely to have more body fat during childhood if their mother has low levels of Vitamin D during pregnancy, according to scientists at the Medical Research Council Lifecourse Epidemiology Unit (MRC LEU), University of Southampton. Low vitamin D status has been linked to obesity in adults and children, but little is known about how variation in a mother's status affects the body composition of her child. Low vitamin D status is common among young women in the UK, and...

Significant step forward in development of science-based recommendations for vitamin A levels for puppies A collaborative team of researchers, working on behalf of the European Pet Food Industry Federation (FEDIAF), has identified a safe upper level for vitamin A consumption for puppies. The research marks a significant step forward in the development of science-based recommendations for vitamin A levels for puppies and sheds new light on their distinct nutritional needs. This research...

'Browning' white fat by blocking vitamin A metabolism Brown seems to be the color of choice when it comes to the types of fat cells in our bodies. Brown fat expends energy, while its counterpart, white fat stores it. The danger in white fat cells, along with the increased risk for diabetes and heart disease it poses, seems especially linked to visceral fat. Visceral fat is the build-up of fat around the organs in the belly. So in the battle against obesity, brown fat appears to be our...

New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene . This antioxidant is a naturally occurring pigment that gives color to foods such as carrots, sweet potatoes and certain greens.

Golden Rice is a variety of Oryza sativa rice produced  through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of the rice. The research was conducted with the goal of producing a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A, a deficiency which is estimated to kill 670,000 children under five years old each year. Golden rice is different from its parental strain by the addition of three...
