Many things change in space, including how the intestines function. Constipation is a known side effect of space travel, but until now, little has been known about why it happens. Constipation is a familiar problem for astronauts, but the biological reason it develops during spaceflight has remained uncertain. Researchers from the University of Copenhagen working [...]

A compound produced in the body after eating pomegranates improved heart function by up to 80% in experimental models of a type of heart failure with limited treatment options. For people with heart failure with preserved ejection fraction, the heart can still pump blood but struggles to relax and refill properly between beats. In experimental [...]

Fat does not only collect under the skin or around the waist. Small amounts of fat can also build up inside muscle cells, and too much of it may interfere with the way muscles use energy. This type of fat buildup becomes more common with aging, physical inactivity and diets that are high in fat. […] The post Blueberry Compound May Help Muscles Burn Fat appeared first on Knowridge Science Report .

Japan-based research has found that pterostilbene — a natural compound found in blueberries, grapes, and other berries — may help muscle cells burn excessive fat rather than storing it. The researchers found that the compound reduced the buildup of abnormal fat in mouse cells, boosted fat breakdown, and stabilized a key protein associated with fatty acid metabolism. The research team stresses tha…

Almost one in three adults in the United States are deficient in iron, but the diagnosis is often missed by doctors.

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study can…

Four Weeks of a Vegan Diet Alter Signs of Inflammation and Aging Nutrition study involving 48 healthy adults / Researchers analyze more than 800,000 genetic loci / Evidence of changes in inflammatory processes, metabolism, and biological aging Just four weeks of dietary changes can already be reflected in epigenetic changes. This is shown by a study conducted by theUniversity Center for Naturopat…

A large study involving more than 270,000 people has linked higher blood levels of the amino acid tyrosine to a shorter lifespan in men. Using both observational data and genetic analysis, researchers found that elevated tyrosine could potentially reduce male life expectancy by nearly a year, while no significant effect appeared in women. Tyrosine is found naturally in protein-rich foods and is a…

Foods that directly influence the actions of GABA and serotonin can calm the mind and aid in falling asleep.

Eating disorders and obesity have traditionally developed as separate fields, but closer dialogue could improve assessment, treatment, and research.

Women with the most antioxidant-rich diets had a strikingly lower prevalence of cervical cancer in a nationwide analysis. A cervical cancer diagnosis is usually traced back to one dominant cause: persistent infection with a high-risk strain of human papillomavirus (HPV). But infection alone does not determine who develops cancer, leaving researchers interested in the other [...]

Sorbitol, a sugar alcohol commonly used in sugar-free candy, gum, and other low-calorie foods, may not be as harmless as it seems. Researchers at Washington University in St. Louis found that the body can convert sorbitol into a form of fructose in the liver, potentially triggering some of the same harmful metabolic effects linked to fructose.

Two people can follow nearly the same low-carbohydrate diet and get very different cholesterol results. One may improve several health markers with almost no change in LDL cholesterol, while the other may see LDL climb to a level that causes concern. A new study suggests that part of the answer may be written in our […] The post How a Low-Carb Diet Changes Your Cholesterol Levels appeared first o…
