Happy Spring. Eat all the eggs you want - 12 eggs per week for 3 months did not elevate people's LDL (bad) cholesterol levels. High egg consumption did not have an adverse effect on the lipid profile of people with type 2 diabetes (T2D) in the context of increased MUFA and PUFA consumption. This study suggests that a high-egg diet can be included safely as part of the dietary management of T2D, and it may provide greater satiety.
Greater dairy intake, esp. fermented and low fat products, aids chronic disease prevention - Greater dairy intake, especially of fermented dairy products, was associated with improved glucose homeostasis/insulin sensitivity, which, interestingly, was independent of obesity status. Whey protein results in a reduced number of chylomicron particles, which may provide reduced cardiovascular disease (CVD) risk, although whether long-term daily consumption of 60 g whey protein as used in this study is likely to be achieved by free-living individuals may be questionable. The study highlights the important role that milk proteins play in chronic disease prevention. Although there is also evidence that milk proteins play a key role in blood pressure control, it was also shown that whey protein but not casein can reduce vascular stiffness, an emerging CVD risk factor.
Older men with muscles are 36% less likely to die from 65 to age 80 - Taking fat mass index (FMI) and fat-free mass index (FFMI) into account, low FFMI is a stronger predictor of mortality than is BMI in older men but not older women. FMI had no impact on mortality. The highest quartile of men were 36% less likely to die during the study.
One serving of nuts a day decreased mortality by 27% - One-serving of nuts per week and per day resulted in 4% and 27% decreased risk of all-cause mortality, respectively, and decreased risk of CVD mortality [RR: 0.93and 0.61), respectively]. Effects were primarily driven by decreased coronary artery disease deaths rather than stroke deaths. Nut consumption was also associated with decreased risk of cancer deaths when highest compared with lowest categories of intake were compared. Nut consumption is associated with lower risk of all-cause, CVD, and cancer mortality.
Vegetable and dairy are fine to eat, but meat consumption produces harmful body fat - Visceral (VAT) and subcutaneous abdominal (SAAT) and trunk (STRAT) adipose tissue (AT) have been suggested to be differentially influenced by diet. Whereas VAT (16.6%) was primarily explained by nutrient quality, SAAT (6.9%) and STRAT (7.4%) were mainly explained by total energy intake. VAT was positively associated with nutrients characteristic of animal (except for dairy) products, including arachidonic acid, but negatively with dietary fiber. VAT may be particularly associated with sex-specific interplays of nutrients found in animal products and fiber, whereas SAAT and STRAT are associated with total energy intake.
Endometrial cancer risk reduced 41% by omega-3 intake unless you are obese - Inflammation may be important in endometrial cancer development. Long-chain ω-3 (n–3) polyunsaturated fatty acids may reduce inflammation and, therefore, reduce cancer risk. Because body mass is associated with both inflammation and endometrial cancer risk, it may modify the association of fat intake on risk. Long-chain ω-3 intake was associated with reduced endometrial cancer risk only in normal-weight women.
Fish oil helps preserve vision in premature infants - Retinopathy of prematurity (ROP) is a vision-threatening disease in premature infants. Dietary ω-3 (n–3) long-chain polyunsaturated fatty acids (ω-3 LCPUFAs) suppress ROP and oxygen-induced retinopathy (OIR) in a mouse model of human ROP. Our findings suggest that increasing APN by ω-3 LCPUFA supplementation in total parental nutrition for preterm infants may suppress ROP.
Grocery store discounts boost purchase of unhealthy choices - We examined the following questions: 1) Are less-healthy foods more likely to be promoted than healthier foods? 2) Are consumers more responsive to promotions on less-healthy products? 3) Are there socioeconomic differences in food purchases in response to price promotions? There was no significant gap in the frequency of promotion by the healthiness of products. The sales uplift arising from price promotions was larger in less-healthy than in healthier categories.
An effective national program for dealing with acute malnutrition in children in developing nations - An estimated one-third of the world’s children who are wasted live in India. In Bihar state, of children <5 y old, 27.1% are wasted and 8.3% have severe acute malnutrition (SAM). In 2009, Médecins Sans Frontières (MSF) initiated a community-based management of acute malnutrition (CMAM) program for children aged 6–59 mo with SAM. To our knowledge, this is the first conventional CMAM program in India and has achieved low mortality and high cure rates in nondefaulting children.
