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...

Potential Dark Side To Diets High In Beta-Carotene
2012-05-01 12:08:08

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. It also converts to vitamin A, and foods and supplements are the only sources for this essential nutrient. But scientists at Ohio State University have found that certain molecules that derive from beta-carotene have an opposite effect in the...

In a study that measured vitamin D levels in the umbilical cord blood of Houston-area infants, Hispanic infants were found to have lower levels of vitamin D, according to researchers at the USDA Agriculture Research Service Children's Nutrition Research Center at Baylor College of Medicine and Texas Children's Hospital. The report appears in the current issue of BMC Pediatrics. "Although the vitamin D levels in Hispanic infants were low, the study did not show that the infants had any...

Elsevier, a world-leading provider of scientific, technical and medical information products and services, announced today the publication of a position statement by the European Menopause and Andropause Society (EMAS) in journal Maturitas on the role of vitamin D in postmenopausal women with summary recommendations. Vitamin D deficiency is common and may affect up to 70% of Europeans. It is classified as a public health issue as it can contribute to many diseases, especially osteoporosis....

Scientists at University College Dublin, Ireland, have identified a genetic alteration which causes a child to be born with no eyes — a condition called anophthalmia. According to the findings published in the current issue (December 2011) of Human Mutation, a child's eyes will not develop fully in the womb if the child has alterations in both copies of its STRA6 gene which is responsible for transporting vitamin A into the cells. This new discovery means that scientists can now...

Deficiency may hinder recovery A new study indicates that many patients undergoing spine surgery have low levels of vitamin D, which may delay their recovery. In a study of 313 patients undergoing spinal fusion surgery, orthopaedic surgeons at Washington University School of Medicine in St. Louis found that more than half had inadequate levels of vitamin D, including one-fourth who were more severely deficient. The researchers report their findings today at the 26th Annual Meeting of...

Golden Rice
2013-10-02 14:11:48

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...
