Researchers from the University of Louisville in Kentucky suggest that natural polyphenols found in pomegranate can fight symptoms of inflammatory bowel disease (IBD). Polyphenols are also present in berries such as strawberries, blackberries, and raspberries.
scientists found a metabolite named urolithin A (UroA) is produces as a result
of polyphenols in fruits and gut bacteria interacting. Using animal model, the
researchers demonstrated UroA and UAS03 increase proteins that tighten
epithelial cell junctions in the gut.
study author Dr Rajbir Singh comments: “The general belief thus far in the
field is that urolithins [such as UroA and UAS03] exert beneficial effects
through their anti-inflammatory, anti-oxidative properties. We have for
the first time discovered that their mode of function also includes repairing
the gut barrier dysfunction and maintaining barrier integrity.”
A recent study, published in the journal Nature Medicine, shows that microbiota, aka gut bacteria, play a crucial role in protecting humans against food allergies.
During the study, two groups of mice without their own bacteria received gut bacteria from either healthy human babies, or from human babies with cow’s allergy milk. The first group of mice didn’t experience any allergic reaction to cow’s milk, while the other had allergic reactions to cow’s milk.
Senior study author Cathryn R. Nagler, Ph.D., a professor in food allergy at the University of Chicago in Illinois, USA, says: “This study allows us to define a causal relationship and shows that the microbiota itself can dictate whether or not you get an allergic response.”
According to number of observational studies and clinical trials carried out over approximately forty years, higher intake of fiber and whole grains (25–29g or more daily) is associated with lower risk of developing non-communicable diseases.
Non-communicable (or chronic) diseases are the conditions of long duration and normally slow progression. They include four types of diseases: cardiovascular (heart attacks and stroke), cancer, chronic respiratory diseases (chronic obstructed pulmonary disease and asthma), and diabetes.
Corresponding author Professor Jim Mann from the University of Otago, New Zealand, say: “Previous reviews and meta-analyses have usually examined a single indicator of carbohydrate quality and a limited number of diseases so it has not been possible to establish which foods to recommend for protecting against a range of conditions. Our findings provide convincing evidence for nutrition guidelines to focus on increasing dietary fibre and on replacing refined grains with whole grains. This reduces incidence risk and mortality from a broad range of important diseases.”
A new study from the United States finds that certain nutrients in a mother’s diet may reduce the influence of the Alzheimer’s disease on offspring.
study, researchers bred mice, genetically predisposed to Alzheimer’s disease
from females whose diet was high in choline, a compound similar to B vitamin
group which can be found in liver, meat, fish, nuts, spinach, eggs, peas,
beans, wheat germ.
Having performed the examination, the scientists discovered that offspring of the females with choline-rich diet showed fewer condition-associated brain changes and improved cognitive performance compared to offspring of non-supplemented mice.
Lead study author Dr. Ramon Velazquez of the Biodesign Institute at ASU comments: “Choline deficits are associated with failure in developing fetuses to fully meet expected milestones like walking and babbling.
According to a new study, published in The BMJ, artificial sweeteners have no benefits or harms to human health.
For the study, a
team of scientists assessed 56 research papers which included adult
and child participants. They examined a range of parameters,
including oral health, kidney and cardiovascular disease, cancer,
blood sugar levels, behavior, mood, and, importantly, weight and body
the authors write: “For most
outcomes, there seemed to be no statistically or clinically relevant
difference between [non-sugar sweetener] intake versus no intake or
between different doses of [non-sugar sweeteners].”
According to recent British research, giving up alcohol for just one month may bring lasting health benefits. Researchers report that people who didn’t drink the whole of January in 2018 had higher energy levels and healthier body weight.
For research, a team of scientists analyzed data collected during Dry January initiative through online surveys. In total, the researchers examined data from 2,821 participants.
The lead researcher Dr. Richard de Visser from the University of Sussex says: “The simple act of taking a month off alcohol helps people drink less in the long term; by August, people are reporting one extra dry day per week. There are also considerable immediate benefits: nine in 10 people save money, seven in 10 sleep better, and three in five lose weight.”
