A study found that vitamin A's carrier protein, retinol-binding protein (RBP), was significantly lower in obese subjects than nonobese subjects. This suggests a potential link between RBP and insulin resistance in obesity. Further research is needed to determine the role of apo-RBP, an unbound form of RBP, in mediating insulin signaling.

Research suggests that higher doses of vitamin A do not improve health outcomes for mothers and children in areas with moderate deficiency. Lower doses, as recommended by the WHO, may be sufficient to prevent mortality. The findings urge caution against increasing standard dosing schedules without further investigation.
Cornell researchers identified a genetic mutation in orange cauliflower that allows it to hold more beta-carotene, a precursor to vitamin A. This finding may lead to more nutritious staple crops by increasing their ability to store beta-carotene.
A study published by the American Academy of Neurology found that weight loss surgery can lead to vitamin B1 deficiency, resulting in memory loss, confusion, and other neurological problems. The syndrome, known as Wernicke encephalopathy, affects the brain and nervous system when the body lacks sufficient thiamine.
A meta-analysis of 68 randomized trials found that antioxidant supplements beta carotene, vitamin A, and vitamin E were associated with increased mortality risk. Vitamin C showed no significant association, while selenium use tended to reduce mortality risk.
Researchers at Albert Einstein College of Medicine have found the mechanism by which folates in the diet are absorbed by the intestinal tract, solving a longstanding mystery. A genetic test can now detect hereditary folate malabsorption, a rare but potentially fatal disorder, allowing for early treatment and supplementation.
Consumption of fortified milk significantly reduces diarrhea and acute lower respiratory illness among preschool children in developing countries. The study found that fortified milk reduced the number of days with severe illness by 15 percent and incidence of pneumonia by 26 percent.
Researchers found three patients over 65 with extensive intestinal surgery developing vitamin A deficiency despite taking supplements. Vitamin A injections improved vision within days, highlighting the growing concern of vitamin A deficiency in affluent countries.
A case study highlights the importance of monitoring vitamin B1 deficiency in post-gastric bypass surgery patients due to potential development of Wernicke encephalopathy. The patient experienced symptoms such as nausea, fatigue, and hearing loss, which improved with increased intravenous dose of vitamin B1.
Research reveals that many poor children in low-income countries are missing out on effective child survival strategies, including vitamin A supplements, safe water, and immunizations. Countries with higher coverage rates have less inequity than those with lower coverage rates.
Researchers found that a natural product of vitamin A can regulate immunity and enhance vaccine response when combined with PIC. The combination resulted in a four to seven times better immune response compared to individual treatments.
Researchers found that reduced CRBP-I function compromises RAR activity, leading to loss of cell differentiation and tumor progression. The study suggests that somatic CRBP-I loss may contribute to breast cancer development and highlights the need for further research into vitamin A's role in cancer prevention.
Dr. Alfred Sommer receives the prestigious Pollin Prize for his groundbreaking research on vitamin A supplementation, saving millions of children's lives worldwide. Dr. Parul Christian is awarded a $100,000 fellowship stipend to continue her work on maternal nutrition and infant mortality in developing countries.
A review of herbal and nutritional supplements found eight products associated with clinically significant ocular side effects, including ginkgo biloba, Echinacea purpurea, chamomile, licorice, canthaxanthine, Datura, niacin, and vitamin A. The side effects range from dry eye to retinal hemorrhages and transient visual loss.
A K-State researcher found a link between smoking, vitamin A deficiency and emphysema in rats. The study shows that benzopyrene, a common carcinogen in cigarettes, induces vitamin A deficiency, which can lead to increased emphysema scores.
A study by Kaiser Permanente found that targeted interventions to increase multivitamin use among women of childbearing age had no significant long-term impact. Despite efforts to educate healthcare providers and pharmacists, the success of these interventions was hampered by inadequate implementation and lack of behavioral change.
Vitamin A supplements have saved millions of lives by preventing childhood blindness and reducing mortality rates. Dr. Alfred Sommer's research also shows that supplementing women with vitamin A can reduce maternal mortality by an average of 45 percent.
A study found that increasing Vitamin B-6 intake rapidly improved its status and decreased DNA strand breaks in both smokers and non-smokers. The researchers also suggested that Vitamin B-6 has a high prevalence of inadequate dietary intake in the general population, particularly among smokers.
A study by Cornell University professor Michael C. Latham shows that a fortified orange drink improves iron and vitamin A status, reducing anemia risk by 51% in pregnant Tanzanian women. The supplement is also found to improve breast milk vitamin A levels and has potential to boost nutrition worldwide.
The NWO study found that children receiving iron, zinc, and vitamin A supplements during pregnancy have better resistance to disease. Zinc deficiency is often linked to the same causes as iron deficiency, resulting from one-sided nutrition lacking animal products.
