Higher intake of some vitamins and carotenoids is linked with a significantly lowered risk for ARC (age-related cataract) in cohort studies, as per to an analysis published in AJCN (The American Journal of Clinical Nutrition). Hong Jiang—of XJTU’s (Xi’an Jiaotong University) Health Science Center, China—along with colleagues carried a meta-analysis of RCTs (randomized controlled trials) and cohort studies issued through June 2018 to evaluate dietary vitamin and carotenoid consumption and ARC risk. The scientists included 12 cohort studies and 8 RCTs during the analysis. The scientists disclosed that most carotenoids and vitamins were considerably linked with a lowered risk for ARC in the cohort studies, counting RR (relative risk) as: vitamin A (RR = 0.81), vitamin E (RR = 0.9), vitamin C (RR = 0.8), β-carotene (RR = 0.9), and zeaxanthin or lutein (RR = 0.81).
In RCTs, correlated with placebo, β-carotene or vitamin E did not considerably lower the risk for ARC. In cohort studies, the jeopardy for ARC significantly reduced by 26% for every 10-mg/d raise in zeaxanthin or lutein intake, plus by 18% for each 500-mg/d raise in vitamin C consumption, by 8% for each 5-mg/d raise in β-carotene consumption, and by 6% for every 5-mg/d raise in vitamin A intake. The researchers stated, “If we can postpone the onset of ARC by 10 Years, it can divide the number of individuals requiring surgery.”
On a similar note, recently, a study stated that prenatal high-dose of vitamin D is not associated with asthma at age 6. High-amount vitamin D supplementation during pregnancy is not linked with a child’s peril for asthma at 6 Years age, as per to research published in the JAMA (Journal of the American Medical Association). Zicklas Brustad—of Herlev and Gentofte University Hospital, Copenhagen—along with colleagues followed children from the COPSAC (Copenhagen Prospective Studies on Asthma in Childhood) 2010 vitamin D RCTs to age 6 Years to examine the risk for current asthma.
