'Positive Impact On Metabolic Syndrome And Satiety Offered By Eggs'

At Experimental Biology (EB) 2012 in San Diego, experts convened to discuss the latest science in a variety of health and disease-related areas, including nutrition. Research on whole egg consumption in individuals with metabolic syndrome as well as the positive effects of a higher-protein breakfast is further revealing the potential benefits of including eggs in the diet.

Whole Egg Consumption May Improve Markers of Metabolic Syndrome

A University of Connecticut study presented this week suggests that eating eggs may actually have favorable effects on HDL metabolism in men and women with metabolic syndrome.(i) Participants in the study followed a carbohydrate-restricted diet with some individuals eating three whole eggs per day and others eating an equivalent amount of egg substitute. After 12 weeks, the group eating whole eggs experienced an improvement in HDL measures showing significantly greater increases in the number and size of HDL particles. HDL or "good" cholesterol scavenges for fat throughout the bloodstream and returns it to the liver, making it less likely that fatty deposits will build up in the blood vessels and lead to atherosclerosis.

Related findings were also presented in separate sessions that suggest that consuming whole eggs as part of a carbohydrate-restricted diet may help to further improve markers indicative of inflammation, such as tumor necrosis factor-alpha, in individuals with metabolic syndrome.(ii)

Higher-Protein Breakfast Reduces High-Fat Snacking

A study by researchers at the University of Missouri found that teen girls reported greater feelings of satiety and experienced improved hormone responses related to hunger and satiety after consuming a higher-protein breakfast, containing about 35 grams of protein from egg or beef-based foods. Teen girls who consumed a high-protein breakfast also ate fewer snacks, especially those higher in fat, later in the day.(iii) These findings build on past research showing the benefits of high-quality protein on satiety, further supporting the science behind what makes eggs such a satisfying breakfast choice.(iv)

Clarifying Cholesterol Confusion

Many Americans avoid the dietary cholesterol found in eggs for fear of raising their risk of heart disease, but more than 40 years of research has shown that healthy adults can enjoy eggs without concern for increasing their risk for heart disease. Additionally, an analysis from the United States Department of Agriculture's Agricultural Research Service showed that eggs have 14 percent less cholesterol (down from 215 mg to 185 mg) than previously measured.(v) Established research also has shown that saturated fat intake may be more likely to raise a person's blood cholesterol than dietary cholesterol intake and eggs contain relatively little saturated fat.(vi) The findings presented at this week's meeting in combination with the decades of science demonstrating the health benefits of eating eggs further support the role of eggs in a nutritious diet.

This piece about eggs is a PR article by Edelman PR agency, not a serious piece of research. Richard Edelman, the CEO's, current assignments include work for the National Dairy Council.

This adds support to previous study results that low carb/high fat diets may be favorable in patients with the metabolic syndrome. Generalized diet recommendations that apply to everybody are not justified.

Caring For The US Navy's Animal Warriors Could Have Impact On Human Health

'Caring For The US Navy's Animal Warriors Could Have Impact On Human Health'

Military patrol dogs with your keen sense of smell, step aside. The U.S. Navy has enlisted the biological sonar and other abilities of bottlenose dolphins and California sea lions to protect harbors from enemy swimmers, detect explosives on the seafloor and perform other tasks. An article in the current edition of Chemical & Engineering News (C&EN) focuses on the Navy's health program for marine mammals and how it may also help keep people healthy.

C&EN Associate Editor Lauren K. Wolf explains that the Navy invests a lot of time and money in training these animals and, naturally, wants to keep them in tip-top shape when they deploy to places like Iraq or Korea. Their missions can involve guiding sailors through mine-laden waters or attaching recovery lines to lost equipment on the seafloor. When one of the roughly 120 animals gets sick, a team of veterinarians carefully evaluates and treats its illness. Because of the Navy's medical care, the animals are living two and three times longer than is common in the wild, leading to illnesses also seen in older humans, like high cholesterol and chronic inflammation. Wolf reports that the Navy is looking to apply its growing understanding of ailments in marine mammals to develop advances in human medical care.

For instance, vets have noticed that dolphins show symptoms similar to diabetes, with spiking blood sugar after meals, but they are able to live with the condition. Wolf says the researchers are looking for a genetic "switch" the dolphins might use to control their diabetes that could lead to treatments for humans living with the disease. Similarly, dolphins show extraordinary healing abilities that Navy researchers think may be linked to the animals' stem cells. The scientists are extracting stem cells from dolphins and testing to see whether their application can speed up wound healing and reduce scarring. If successful, the technique may one day be useful for humans, too.

Community Factors And Racial Make-Up Impact Obesity Risk

Community Factors And Racial Make-Up Impact Obesity Risk

The racial and ethnic composition of a community is associated with the obesity risk of individuals living within the community, according to a study led by researchers at the Agency for Healthcare Research and Quality (AHRQ) and the Johns Hopkins Bloomberg School of Public Health. The findings, published in the American Journal of Public Health, may help explain disparities in obesity rates among racial groups and point to some of the environmental factors that may contribute to obesity in the United States.

For the study, the researchers analyzed data from the Medical Expenditure Panel Survey, which represented a cross-section of the U.S. population. The data were matched with geographical information from the U.S. Census. Obesity was calculated based on each study participant's body mass index (BMI), a measure of weight in relation to height.

Analysis of the data found that community ethnic composition might affect residents' likelihood of being obese, and the effect varied by the residents' own ethnicity, for example, living in a community with a Hispanic population of 25 percent or greater was associated with 21 percent higher odds for obesity for Hispanics in that community. Non-Hispanic whites had 23 percent higher odds for obesity living in the same community.

The opposite was true for communities with high concentrations of non-Hispanic Asians. In those communities, the odds for obesity were 28 percent lower for non-Hispanic whites in those communities. While non-Hispanic blacks have the highest rates of obesity in U.S., living in a community with a high concentration of non-Hispanic blacks did not raise the odds of obesity even among non-Hispanic blacks.

"Obesity is one of the nation's most pressing health problems, and our findings suggest that community characteristics related to racial and ethnic composition may have an important effect on residents' weight," said James B. Kirby, PhD, of the Agency for Healthcare Research and Quality, who was the lead author of the study. "This study will enhance understanding of the disparities in the U.S. obesity epidemic and how certain racial and ethnic minorities are disproportionately affected."

"Social and built environments play an important role in influencing individuals' health outcomes including obesity. Future research needs to better understand the mechanisms, but clearly interventions are needed to reduce obesity disparities in the United States," said Youfa Wang, MD, PhD, MS, coauthor of the study and director of the Johns Hopkins Global Center on Childhood Obesity and Associate Professor at the Bloomberg School of Public Health.
