A new study found that puberty causes a general metabolic slowdown in both white and African American adolescents, with African Americans having greater lean mass in limbs but lower lean mass in the trunk. This difference may contribute to a lower resting energy expenditure (REE) in African Americans.
A study published in the American Journal of Clinical Nutrition found that energy-restricted diets had the most beneficial effects on serum lipids, lowering triglycerol concentrations and elevating HDL cholesterol. The authors suggest reevaluating current low-fat diet recommendations for individuals with excess body weight.
A study found that consuming high-procyanidin chocolate increased plasma concentrations of a procyanidin metabolite and reduced serum leukotriene, promoting blood platelet aggregation. This compound may provide cardioprotective effects by inhibiting platelet aggregation.
Adults exposed to Dutch famine in utero exhibit abnormal lipid profiles, with significantly higher total cholesterol and LDL cholesterol levels. Maternal malnutrition in the first trimester permanently alters offspring lipid profiles later in life.
A one-year study found that moderate vitamin E supplementation can slow the oxidation of LDL cholesterol in diabetics, reducing their risk of cardiovascular disease. The authors suggest that uninterrupted long-term supplementation may be preferable over short-term 'cures' using high-doses or intravenous administration.
The study found that the global prevalence of overweight among infants and children aged 0-5 years is 3.3%, with some countries having very high rates of both overweight and wasting. Developing countries in the Middle East, North Africa, and Latin America have the highest prevalences of overweight.
Consumers who consumed high amounts of energy-dense, nutrient-poor foods had lower serum concentrations of vitamins and micronutrients, as well as higher levels of homocysteine. This study highlights the need for new strategies to educate consumers on moderating their EDNP food intake.
The average American consumes 27% of their daily energy from junk foods, which can lead to nutritional and health issues. The study found that those who consumed more healthy foods like fruits and vegetables were less likely to develop heart disease.
A new study from Michigan Medicine shows that color-coded labels on supermarket shelves can guide shoppers to healthier food choices, particularly among African Americans. The program may lower the risk of diet-related health problems like heart disease.
A study found that women with low-fat diets had 19% lower fractional calcium absorption rates than those with high-fat diets. The authors propose that fat may increase calcium absorption by slowing transit time through the intestines.

The unit will focus on enhancing the use of laboratory discoveries in population-based and clinical research, as well as educating health professionals about nutrition.
The long-term study found that orlistat helped successful dieters keep weight off. The accompanying editorials suggest that orlistat's benefits are modest.
A meta-analysis of formerly obese individuals who lost weight found that their resting metabolic rate decreased, explaining why dieters struggle to maintain weight loss. This decrease in metabolism may be a key factor contributing to the difficulty in keeping excess weight off.
The IFT Meeting will address key nutrition topics, including the impact of new dietary reference intakes on industry and public policy. The event also highlights the nutritional needs of older adults, particularly those turning age 65 each year, who are at increased risk for nutrient deficiencies.
A Penn State study suggests that eating low-energy-density meals, which contain fewer calories per ounce and are rich in fruits, vegetables, or grains, can help individuals manage their weight while still feeling full and satisfied. The study found that the energy density of food, rather than fat content, plays a key role in satiety.
Researchers found a strong relationship between reading nutrition labels and eating less fat. People who read labels tend to consume 30% or less of their daily calories from fat, compared to 35% for non-label readers.
Researchers at Penn State have discovered specific compounds in garlic that lower cholesterol levels by inhibiting liver cell production. The study found three water-soluble sulfur-containing compounds that decreased cholesterol production in cultured rat liver cells by 40 to 60 percent, with potential implications for heart health.
A recent study found that 57% of patients who received nutrition counseling felt better emotionally after the visit, while nearly 65% felt more in control of their illness. The researchers also found improvements in health, such as weight loss and improved blood pressure, among 44% of patients.
A study found that leptin decreases in response to energy deficit in women, leading to increased hunger and desire to eat. Leptin's role in regulating food intake is supported by the association between leptin levels and self-reported hunger.
A new consortium of experts plans to increase the number of physician nutrition specialists on medical school faculties, establish educational standards for post-graduate training, and promote accreditation and monitoring. The goal is to help create a supply of nutrition professionals who can inform medical curricula and patient care.
A growing recognition of age differences in dietary needs is driving calls for separate guidelines for children. Key findings include the importance of sound scientific evidence and gradual changes to a child's diet, with monitoring of growth by health professionals at regular intervals.
A study investigated the understanding of common food label quantifier terms among consumers, revealing significant discrepancies between their perceptions and FDA regulations. Consumers tended to overestimate the amounts of components affected by these terms.
The American Heart Association recommends using oils in their natural state for cooking, and choosing softer margarines over harder ones for spreads. New guidelines suggest that these choices can help lower total fat intake and reduce trans fatty acid consumption.
A Penn State study found that teenagers prioritize health concerns when shopping, but primarily rely on front-of-label nutrition claims. Researchers suggest educational programs to improve food shopping and label reading skills.
The Nutrition Analysis Tool (NAT) allows users to analyze the nutrients in over 5,200 common food items based on daily allowance data from the US Department of Agriculture.
