Have all the vitamin D researchers been on vacation? Who would believe that it has been almost a month since our last blog on vitamin D? Today’s blog highlights a new scientific report on the role of vitamin D in older adults. Takehome message: “Plasma 25(OH)D concentrations predict subsequent lower 13-y total mortality and incident cardiovascular disease, respiratory disease, and fractures.”
Long-chain polyunsaturated fatty acid (LCPUFA) experts have been busy publishing reviews on the health benefits of omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
The Early Nutrition Academy supported a systematic review of human studies on the roles of pre- and postnatal LCPUFA. Using the most recent studies (2008-2013), Koletzko and colleagues report:
For the past decade, health professionals have ignored vitamin E. Even the 2010 Dietary Guidelines Advisory Committee chose not to identify vitamin E as a ‘nutrient of concern’ although it was identified as one of 10 nutrients (Vitamins A, C, D, E, and K, choline, calcium, magnesium, potassium and dietary fiber) missing from our diet.
Plants make 8 different forms of vitamin E but only α-tocopherol is maintained in plasma and tissue. Only the 2R-stereoisomeric forms of α-tocopherol reverse vitamin E deficiency and meet human vitamin E requirements.
Monday morning blues. An ecological analysis of databases by the Food Agricultural Organization (FAO), World Health Organization (WHO), and World Bank finds a direct dose-response association between the adoption of a sedentary lifestyle with western dietary patterns and the global rise in diabetes prevalence. Depressing news.
What does it take to help people make healthier lifestyle choices? For years as a professor, I thought the answer was in education. This argument was undermined when the percentage of consumers who could associate foods (and nutrients) with health benefits became apparent .
As a reader, you will know I recommend using nutritional biomarkers to assess health outcomes rather than dietary intake guestimates. Wood and colleagues affirm these statements. They analyzed dietary and biological data obtained from approximately 2,000 Scottish women who attended a baseline visit between 1990-1993 as part of the Aberdeen Prospective Osteoporosis Screening Study (APOSS).
Over the 10 years, their age increased (not surprisingly) as did their body weight (+2 kg), total cholesterol (+0.3 mmol/L), and HDL-C (+0.35 mmol/L).
Millions of children are missing important preventive health care opportunities in the US. Boyle and colleagues report wide divides in use of clinical preventive services by race/ethnicity, geography and health care coverage.
For example, 50% of infants who failed their hearing screening did not receive a follow-up evaluation. Twenty-two percent of children had not had their vision checked professionally by 5y of age. The US has one of the highest per capita incomes but nearly half of American children grow up in families that are poor or near poor (below 199% of the federal poverty level).
When it comes to writing stories about nutrition, facts seem secondary (or even further down the list). Maybe controversy sells. Maybe rich people not only eat more expensive foods but they buy more books and magazines.
The food and supplement industry are not evil. Advances in agriculture and technology are feeding the world. Yesterday at the Arkansas Nutrition Conference sponsored by The Poultry Federation, I learned the efficiency of raising chickens (broilers), measured by feed conversion (adjusted to a 2300g bird), has improved by 15%
The World Health Organisation has named vitamin A deficiency to be a public health problem in over half of all countries. Vitamin A is needed for vision, and also to prevent infections. Various public health measures are used around the world to help people with deficient diets to meet their vitamin A needs, such as food fortification, supplementation programs, improving dietary diversity and increasing the pro-vitamin A content of staples through bio-fortification. But there is no “one size fits all” measure to improve vitamin A status. We explain further.
