Most people do not consume enough fatty fish containing long chain omega-3 polyunsaturated fatty acids (ω-3 LCPUFAs). Consequently, our intake of the ω-3 LCPUFAs - eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) – is low. ω-3 LCPUFAs help reduce production of triglycerides by the liver and increase triglyceride clearance. Increasing ω-3 LCPUFA intake can also increase HDL-cholesterol concentrations. Based on this evidence, the FDA approved the use of […]
Today, two studies that conducted clinical trials using food appeared on my nutrition research radar: a study by Navarro and co-workers looking at the effect of cruciferous vegetables on markers of inflammation, and another by Pereira-Caro and colleagues on the bioavailability of polyphenols from orange juice. What do these types of studies tell us about health benefits of foods and phytonutrients?
Krill oil has hit the Omega-3 supplement market as an alternative to fish oil, touting claims of better absorption. But is it really true? A recent re-examination of the evidence challenges these assumptions.
Hansen and colleagues report on how parents’ perceptions of childhood overweight have changed over 15 years. Comparing sampling periods from 1988-1994 with 2005-2010, the researchers found that the probability that parents correctly identify their child as overweight decreased by 16% between the two study periods, with more parents thinking that their overweight or obese child had a weight that was about right. What is going on here?
Antioxidants protect us. Our bodies have many interrelated systems to protect our cells and tissues. Vitamin E (α-tocopherol) is the most abundant lipid-soluble antioxidant in our bodies. It is co-located within cell membranes to protect polyunsaturated fatty acids from peroxidization. Vitamin E, as well as other antioxidants such as vitamin C and selenium, help protect DNA and proteins from oxidation. Vitamin C is required to regenerate vitamin E.
