Published New study challenges one-size-fits-all approach to vitamin D supplementation guidelines
(via sciencedaily.com) Original source A new study sheds light on the complexities of achieving optimal vitamin D status across diverse populations. Despite substantial research on the determinants of vitamin D, levels of vitamin D deficiency remain high. Researchers believe their findings have significant implications for the development of tailored recommendations for vitamin D supplementation.
Published Dietary changes may treat pulmonary hypertension
(via sciencedaily.com) Original source Blood vessels in the lungs aren't like the others in the body. This difference becomes clear in pulmonary hypertension, in which only the lungs' blood vessels stiffen progressively, leading to chronic lung disease, heart failure and death. The underlying reasons for this organ-specific vessel stiffening remained a mystery until researchers made a surprising discovery about these blood vessel cells in patients with pulmonary hypertension -- they're hungry.
Published Nutrient research reveals pathway for treating brain disorders
(via sciencedaily.com) Original source The team discovered that an essential nutrient called choline is transported into the brain, across the blood-brain barrier, by a protein transporter called FLVCR2. This is discovery will inform future design of drugs for diseases such as Alzheimer's and stroke, mimicking choline so they can be smuggled into the brain.
Published An omega-6 fatty acid may reduce the risk for bipolar disorder
(via sciencedaily.com) Original source A genetic propensity to higher circulating levels of lipids containing arachidonic acid, an omega-6 polyunsaturated fatty acid found in eggs, poultry, and seafood, has been found to be linked with a lower risk for bipolar disorder. This new evidence paves the way for potential lifestyle or dietary interventions.
Published Vitamin D alters mouse gut bacteria to give better cancer immunity
(via sciencedaily.com) Original source Researchers have found that vitamin D encourages the growth of a type of gut bacteria in mice which improves immunity to cancer.
Published Guidance on energy and macronutrients across the lifespan
(via sciencedaily.com) Original source In the long history of recommendations for nutritional intake, current research is trending toward the concept of 'food as medicine' -- a philosophy in which food and nutrition are positioned within interventions to support health and wellness.
Published Choosing sugary drinks over fruit juice for toddlers linked to risk of adult obesity
(via sciencedaily.com) Original source Consuming sugar-sweetened drinks in the first few years of childhood can be linked to poor diet patterns that increase the risk of obesity in later life, according to a new study.
Published Obese and overweight children at risk of iron deficiency
(via sciencedaily.com) Original source Children and young people who are overweight or obese are at significantly higher risk of iron deficiency, according to a study by nutritional scientists.
Published Bringing multidrug-resistant pathogens to their knees
(via sciencedaily.com) Original source Multidrug-resistant bacterial infections that cannot be treated by any known antibiotics pose a serious global threat. A research team has now introduced a method for the development of novel antibiotics to fight resistant pathogens. The drugs are based on protein building blocks with fluorous lipid chains.
Published Blended antioxidant supplement improves cognition and memory in aged mice
(via sciencedaily.com) Original source Cell damage from oxidative stress is a major underlying cause of age-related cognitive and muscle strength decline. Antioxidants can reduce oxidative stress and prevent age-related health decline. A new study has found that mice administered with a blended antioxidant supplement show significant improvements in spatial cognition, short-term memory, and mitigated age-related muscle decline. The study suggests that blended antioxidant supplements hold promise as a dietary intervention for health issues associated with aging.
Published Eggs may not be bad for your heart after all
(via sciencedaily.com) Original source Whether you like your eggs sunny-side up, hard boiled or scrambled, many hesitate to eat them amid concerns that eggs may raise cholesterol levels and be bad for heart health. However, results from a prospective, controlled trial show that over a four-month period cholesterol levels were similar among people who ate fortified eggs most days of the week compared with those who didn't eat eggs.
Published Natural molecule found in coffee and human body increases NAD+ levels, improves muscle function during aging
(via sciencedaily.com) Original source A research consortium made a recent discovery that the natural molecule trigonelline present in coffee, fenugreek, and also in the human body, can help to improve muscle health and function.
Published Fish fed to farmed salmon should be part of our diet, too, study suggests
(via sciencedaily.com) Original source Scientists found that farmed salmon production leads to an overall loss of essential dietary nutrients. They say that eating more wild 'feed' species directly could benefit our health while reducing aquaculture demand for finite marine resources.
Published Fatty food before surgery may impair memory in old, young adults
(via sciencedaily.com) Original source Eating fatty food in the days leading up to surgery may prompt a heightened inflammatory response in the brain that interferes for weeks with memory-related cognitive function in older adults -- and, new research in animals suggests, even in young adults.
Published 'Molecular Rosetta Stone' reveals how our microbiome talks to us
(via sciencedaily.com) Original source Researchers have uncovered thousands of previously unknown bile acids, a type of molecule used by our gut microbiome to communicate with the rest of the body.
Published Researchers develop artificial building blocks of life
(via sciencedaily.com) Original source For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory.
Published Vitamin A may play a central role in stem cell biology and wound repair
(via sciencedaily.com) Original source Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound repair.
Published For a healthy fruit snack, what would you choose?
(via sciencedaily.com) Original source Next time you're packing lunch for your kid or reaching for a healthy afternoon bite, consider this: only three types of packaged fruit snacks -- dried fruit, fruit puree and canned fruit with juice -- meet the latest recommendations for high-nutrition snacks set by federal dietary guidelines, according to food scientists.
Published Study results show 25% of pregnant people are not getting enough omega-3 fatty acids from their diet or dietary supplements
(via sciencedaily.com) Original source Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.
Published New role for bacterial enzyme in gut metabolism revealed
(via sciencedaily.com) Original source Bile acids long have been known to play a role in human metabolism. Synthesized from cholesterol in the liver, bile acids are involved in digestive processes, particularly in absorbing fat. They also are modified extensively by bacteria, which greatly expand the types of bile acids found in the host. For most of a century, scientists believed that was the end of the bile-acid story. Recent technological advances, however, have led to a greater understanding of the origins of bile acids as well as their chemical relationships to the organisms in the gut microbiome and their host.
