A recent review of studies on interventions with probiotics, prebiotics and omega-3s shows that there is promising data backing these ingredients’ effects on ameliorating anxiety, stress and depression. But much more research is needed to identify pathways, biomarkers and modes of action.
Scientists have gained a glimpse of how marks on our genes that could be linked to adverse health outcomes in later life behave differently in the first few days after conception, according to new research.
The case for a prebiotic approach as an alternative nutritional treatment against obesity has strengthened with the publication of a review that points to the food ingredient’s beneficial effects on metabolism.
Diets with better asthma outcomes are characterised by being healthier, with greater consumption of fruits, vegetables and whole grain cereals. Unhealthy diets, with high consumption of meat, salt and sugar, have the poorest outcomes.
Using answers from more than 7000 parents who took part in the Children of the 90s longitudinal study about their personality, mood and attitude during pregnancy; similar answers from their children at age of eight and the child's fat mass measurement up to the age of 17, researchers have assessed that a mother's psychological background during pregnancy is a factor associated with teenage weight gain.
Parents' genetic contributions to their offspring influence a child's propensity to obesity. But the steep run-up in child obesity seen in the span of fewer than two generations can't possibly be explained by genes alone. The rate has more than tripled since the 1970s.
People with multiple sclerosis (MS) can find an abundance of conflicting advice suggesting that special diets will ease their symptoms. But the evidence is scanty. A new trial evaluates whether drastically cutting calories twice a week can change the body's immune environment and the gut microbiome, and potentially change the course of the disease.
Nutritional compounds naturally present in green tea and red wine may obstruct the creation of toxic metabolites that contribute to the neurodegeneration seen in Alzheimer's and Parkinson's disease.
UK children consume energy drinks at a higher rate than kids in any other country in Europe - with a fifth of three-10-year-olds having them regularly. Is this a health risk, or no worse than coffee?
A mother’s example could be instrumental in a child maintaining a healthy weight, suggests new research published in The BMJ. In a study of nearly 25,000 children, those whose mothers adhered to five healthy lifestyle factors carried a 75 percent lower risk of obesity than children whose mothers had none of those habits. The factors included a body mass index (BMI) below 25, a high-quality diet, regular exercise, no smoking and low alcohol consumption.
Low vitamin D levels can have serious repercussions for the bone health of both mother and child. Vitamin D is necessary for calcium to be taken up by the intestine. In pregnancy, this vitamin is crucial to ensure sufficient calcium to build the child's bone mass and maintain that of the mother.
An analysis of recent high-quality research reveals that diet may affect individuals' risks related to the development and progression of age-related macular degeneration (AMD). The findings are published in Clinical & Experimental Ophthalmology.
After analyzing data from a national US survey, researchers in China suggest that dietary fiber intake may be inversely related to depression symptoms. The results were consistent even after adjustment for a wide variety of potential confounders.
A mother's diet during pregnancy may have an effect on the composition of her baby's gut microbiome - the community of bacteria living in the gut - and the effect may vary by delivery mode, according to study published in the open access journal Microbiome.
Fortifying grain-based foods with folic acid - instituted in the U.S. in the 1990s to prevent neural tube defects in infants - may also reduce the incidence of severe mental illnesses like schizophrenia that initially appear in young adulthood.
In the last trimester of pregnancy and in the first years of life, our brain undergoes enormous growth, and the omega-3 fatty acid DHA is particularly important for the development of the brain in infants.
New research reveals a cellular mechanism by which good bacteria can help the gut stay healthy. The study, which appears in the journal Immunity, shows that good bacteria, or the microbiota, interact with both the epithelial cells lining the gut and cells of the immune system to help balance the immune responses and protect the gut from unwanted inflammation.
"The changes in the microbiota might affect how much vitamin D a person can metabolize, or how the body metabolizes vitamin D, so there are implications, but it's still early and that remains to be seen," say researchers.
Inhaling the aroma of black tea may help to lower stress levels after a stressful task and improve mood prior to experiencing mental stress, according to emerging research from Japan.
A new study suggests that when a high-fat, high-sugar diet that leads to obesity is paired with normal aging, it may contribute to the development of Alzheimer's disease. In addition, researchers discovered that certain areas of the brain respond differently to risk factors associated with Alzheimer's.
