A recent study found that calcium supplements, especially those containing up to 1,000 mg per day, can lower the risk of death among women. The benefit was seen regardless of whether the supplement contained vitamin D.
A recent NIH study found that adding omega-3 fatty acids and lutein/zeaxanthin to a combination of nutritional supplements does not improve protection against age-related macular degeneration. However, removing beta-carotene from the supplement formulation may help reduce risk, according to researchers.
A large multicenter trial showed that adding lutein and zeaxanthin, omega-3 fatty acids DHA and EPA to an antioxidant vitamins formulation did not reduce the risk of progression to advanced age-related macular degeneration. No significant effects were observed on vision loss development either.

A new study from St. Michael's Hospital found that dietary supplements accounted for more than half of the Class 1 drugs recalled by the US Food and Drug Administration between 2004-12. The majority of these recalls were for bodybuilding, weight loss, or sexual enhancement products containing unapproved medicinal ingredients, including...
A review of 32 randomized controlled trials suggests that mental exercise, such as computerized training programs or intensive one-on-one personal cognitive training, may benefit older adults in preventing cognitive decline. The annual rate of dementia-related cognitive decline is estimated to double to over 1 million Canadians by 2047.
Despite concerns over high vitamin E intake, a new review concludes that the body can eliminate excess levels of the vitamin, making it impossible to take a harmful amount. Vitamin E is essential for proper organ function and has antioxidant properties.
A review of published research found no evidence that drugs, herbal products, or vitamin supplements can prevent cognitive decline in healthy older adults. However, mental exercises such as computerized memory training programs and intensive one-on-one personal cognitive training showed promise.
Research presented at the American College of Cardiology's Annual Scientific Session found no significant benefit from high-dose oral vitamins and minerals in reducing recurrent cardiac events. However, combining these supplements with active chelation therapy showed a slight additional benefit.
A large European study found that eating processed meat was associated with an increased risk of premature death, particularly from cancer and cardiovascular disease. The researchers estimated that up to 3% of premature deaths could be prevented if people consumed less than 20g of processed meat per day.
A European-wide study with 450,000 participants found that eating over 40 grams of processed meat per day increases the risk of mortality compared to those who eat fewer than 20 grams a day. Moderate consumption of up to 40 grams daily does not increase mortality risk.
A study found that morning sickness lasting all day is often linked to hormonal and genetic factors, with ethnicity and diet also playing a role. Women who have experienced hyperemesis gravidarum in previous pregnancies are at higher risk of severe nausea during subsequent pregnancies.
A new study published in Neurology found no correlation between antioxidant intake and risk of developing stroke or dementia. The study suggests that individual antioxidants and food sources may be more important than total antioxidant levels in reducing the risk of these conditions.
