Blueberry juice enhances memory in older adults - Life Extension Update - 1 views

  •  
    In an article published online on January 4, 2010 in the Journal of Agricultural and Food Chemistry, Robert Krikorian of the University of Cincinnati, along with his colleagues from the US and Canadian Departments of Agriculture, report that consuming blueberry juice was associated with improvements in learning and memory in individuals with age-related memory decline.

    The trial enrolled five men and four women over the age of 70 who reported forgetfulness and memory lapses characteristic of early memory decline. Participants were given the equivalent of 2 to 2 ½ cups of a commercially available blueberry juice daily for 12 weeks. Cognitive assessments were conducted at the beginning of the study and during the final week of the trial.

    At the study's conclusion, learning and recall were improved, and depressive symptoms and glucose levels tended to be reduced. When subjects who received blueberry juice were compared with a demographically matched sample who received a placebo beverage in a companion trial, test scores for learning ability were significantly better.

    "High serum selenium associated with elevated LDL and total cholesterol
    By Helen Albert

    Atherosclerosis 2009; Advance online publication

    MedWire News: High levels of serum selenium are associated with elevated total and low-density lipoprotein (LDL) cholesterol, report US researchers.

    The results add weight to those of a previous UK study, reported by MedWire News, that reported an association between high plasma selenium and an adverse lipid profile.

    Eliseo Guallar (Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland) and colleagues carried out a cross-sectional analysis of 1159 individuals aged 56.8 years on average who participated in the National Health and Nutrition Examination Survey (NHANES) 2003-2004."

A Balanced Diet - 2 views

  •  
    The amount of energy to be provided by a balanced diet for any person will depend on several factors: age, sex, body size, lifestyle, occupation, and the climate of the area he is in. The proportion of the various food classes in a diet is also not the same for different persons, due to varying physical and physiological requirements..

    PMID: 20071648
    doi:10.3945/ajcn.2009.27725

    Conclusions: A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD. More data are needed to elucidate whether CVD risks are likely to be influenced by the specific nutrients used to replace saturated fat.

    Consuming fructose-sweetened, not glucose-sweetened, beverages increases visceral adiposity and lipids and decreases insulin sensitivity in overweight/obese humans.

    J Clin Invest. 2009 May;119(5):1322-34. Epub 2009 Apr 20.
    PMID: 19381015
    doi: 10.1172/JCI37385.

    Studies in animals have documented that, compared with glucose, dietary fructose induces dyslipidemia and insulin resistance. To assess the relative effects of these dietary sugars during sustained consumption in humans, overweight and obese subjects consumed glucose- or fructose-sweetened beverages providing 25% of energy requirements for 10 weeks. Although both groups exhibited similar weight gain during the intervention, visceral adipose volume was significantly increased only in subjects consuming fructose. Fasting plasma triglyceride concentrations increased by approximately 10% during 10 weeks of glucose consumption but not after fructose consumption. In contrast, hepatic de novo lipogenesis (DNL) and the 23-hour postprandial triglyceride AUC were increased specifically during fructose consumption. Similarly, markers of altered lipid metabolism and lipoprotein remodeling, including fasting apoB, LDL, small dense LDL, oxidized LDL, and postprandial concentrations of remnant-like particle-triglyceride and -cholesterol significantly increased during fructose but not glucose consumption. In addition, fasting plasma glucose and insulin levels increased and insulin sensitivity decreased in subjects consuming fructose but not in those consuming glucose. These data suggest that dietary fructose specifically increases DNL, promotes dyslipidemia, decreases insulin sensitivity, and increases visceral adiposity in overweight/obese adults.

    Arch Intern Med. 2009 Dec 14;169(22):2053-63.
    PMID: 20008687

    Conclusions Owing to the presence of small-study bias, our results may represent an overestimate of the true magnitude of the association. Similar significant and inverse associations were observed with decaffeinated coffee and tea and risk of incident diabetes. High intakes of coffee, decaffeinated coffee, and tea are associated with reduced risk of diabetes. The putative protective effects of these beverages warrant further investigation in randomized trials.

    C-reactive protein concentration and risk of coronary heart disease, stroke, and mortality: an individual participant meta-analysis.
    The Lancet, Early Online Publication, 22 December 2009
    doi:10.1016/S0140-6736(09)61717-7

    Interpretation
    CRP concentration has continuous associations with the risk of coronary heart disease, ischaemic stroke, vascular mortality, and death from several cancers and lung disease that are each of broadly similar size. The relevance of CRP to such a range of disorders is unclear. Associations with ischaemic vascular disease depend considerably on conventional risk factors and other markers of inflammation.

Quality of HDL differs in diabetics but improves with niacin therapy - theheart.org - 1 views

    "Quality of HDL differs in diabetics but improves with niacin therapy
    December 22, 2009 | Michael O'Riordan

    Hannover, Germany - A small study published this week hints that the effects of HDL cholesterol differ in healthy patients from those with diabetes mellitus [1]. HDL cholesterol in individuals with diabetes has impaired endothelial protective functions compared with the HDL from healthy subjects, although treatment with extended-release niacin can improve these endothelial protective effects, according to researchers.

    Publishing their findings online December 21, 2009 in Circulation, lead investigator Dr Sajoscha Sorrentino (Hannover Medical School, Germany) and colleagues write that because recent HDL-raising intervention studies have yielded mixed results, "circulating HDL-cholesterol levels alone likely do not represent an adequate measure of therapeutic efficacy, and indexes of HDL functionality are urgently needed for assessment of the potential of HDL-targeted therapies to exert vasoprotective effects."

    Speaking with heartwire, senior investigator Dr Ulf Landmesser (University of Zürich, Switzerland), said the results have implications for clinical research.

    "We have to understand that we can't look only at the HDL levels in the plasma, but we need to look at the quality," he said. "The quality of the HDL is not the same in different patients. This is very important for targeting HDL as a treatment. Second, niacin therapy is a promising way not only to raise HDL but also to improve the quality; it is a good treatment option, especially if the larger outcomes data are positive.""

    Conclusions-HDL from patients with type 2 diabetes mellitus and metabolic syndrome has substantially impaired endothelial-protective effects compared with HDL from healthy subjects. ER niacin therapy not only increases HDL plasma levels but markedly improves endothelial-protective functions of HDL in these patients, which is potentially more important.

Vitamin B Niacin Offers No Additional Benefit To Statin Therapy In Seniors Already Diag... - 0 views

  •  
    "The routine prescription of extended-release niacin, a B vitamin (1,500 milligrams daily), in combination with traditional cholesterol-lowering therapy offers no extra benefit in correcting arterial narrowing and diminishing plaque buildup in seniors who already have coronary artery disease, a new vascular imaging study from Johns Hopkins experts shows.

    In tests on 145 Baltimore-area men and women with existing atherosclerosis, all over age 65, researchers found that after 18 months of drug therapy, reductions in arterial wall thickness were measurably no different between the half who took dual niacin-statin therapy and the rest who remained on statin therapy alone.

    J Am Coll Cardiol, 2009; 54:2388-2395,
    doi:10.1016/j.jacc.2009.10.006

    Conclusions: ARIC participants with elevated hs-CRP and low LDL-C had a CVD event rate of 1.57% per year over 6.9 years, similar to the CVD event rate noted in the JUPITER study placebo group (1.36% per year over 1.9 years). The association of hs-CRP ≥2.0 mg/l with increased CVD risk and mortality regardless of LDL-C provides us a simple method of using age and hs-CRP level for identifying higher risk individuals.

    Mozambican Grass Seed Consumption During the Middle Stone Age

    Science 18 December 2009:

    DOI: 10.1126/science.1173966

    The role of starchy plants in early hominin diets and when the culinary processing of starches began have been difficult to track archaeologically. Seed collecting is conventionally perceived to have been an irrelevant activity among the Pleistocene foragers of southern Africa, on the grounds of both technological difficulty in the processing of grains and the belief that roots, fruits, and nuts, not cereals, were the basis for subsistence for the past 100,000 years and further back in time. A large assemblage of starch granules has been retrieved from the surfaces of Middle Stone Age stone tools from Mozambique, showing that early Homo sapiens relied on grass seeds starting at least 105,000 years ago, including those of sorghum grasses.

Observations: Humans feasting on grains for at least 100,000 years - 0 views

  •  
    "Grains might have been an important part of human diets much further back in our history than previous research has suggested.

    Although cupcakes and crumpets were still a long way off during the Middle Stone Age, new evidence suggests that at least some humans of that time period were eating starchy, cereal-based snacks as early as 105,000 years ago. The findings, gleaned from grass seed residue found on ancient African stone tools, are detailed online Thursday in Science.

    Researchers have assumed that humans were foraging for fruits, nuts and roots long before 100,000 years ago, but cereal grains are quite a new addition to the early prehistoric gastronomic picture. "This broadens the timeline for the use of grass seeds by our species," Julio Mercader, an assistant professor at University of Calgary's Department of Archeology and author of the paper, said in a prepared statement.

    J Nutr. 2008 Jul;138(7):1365-71.
    PMID: 18567762

    Compared with baseline, serum parathyroid hormone decreased with both fortification (P = 0.003) and supplementation (P = 0.012). These data demonstrate that vitamin D is equally bioavailable from fortified hard cheeses and supplements, making cheese suitable for vitamin D fortification.

    Bread fortified with cholecalciferol increases the serum 25-hydroxyvitamin D concentration in women as effectively as a cholecalciferol supplement.
    Natri AM, Salo P, Vikstedt T, Palssa A, Huttunen M, Kärkkäinen MU, Salovaara H, Piironen V, Jakobsen J, Lamberg-Allardt CJ.
    J Nutr. 2006 Jan;136(1):123-7.
    PMID: 16365070

    Both fortified breads increased serum 25-hydroxyvitamin D concentration as effectively as the cholecalciferol supplement. Supplementation or fortification did not affect serum intact parathyroid hormone concentration or urinary calcium excretion. In conclusion, fortified bread is a safe and feasible way to improve vitamin D nutrition.
