Researchers have shown that how we respond to changes in nutrients at a molecular level plays an important role in the aging process, and this is directed by some key genetic mechanisms.
A new study suggests that people following a plant-based diet who frequently consumed less-healthful foods like sweets, refined grains and juice showed no heart health benefit compared with those who did not eat a plant-based diet.
A diet including daily avocado consumption improves the ability to focus attention in adults whose measurements of height and weight are categorized as overweight or obese, a new randomized control trial found.
The FDA-approved drug liraglutide has been shown to help obese patients lose weight by suppressing their appetite. However, where and how the drug acts in the brain was not fully understood, until now. A new preclinical study shows how liraglutide crosses the brain's blood barrier to engage with a region of the brainstem known as the nucleus tractus solitarius, which is responsible for balancing food intake and energy expenditure.
New research shows that animals on a prebiotic diet sleep better and are buffered from the physiological impacts of stress. The undigestible dietary compounds, found in fibrous foods and some dairy products, serve as nourishment for beneficial bacteria and influence metabolites that, in turn, impact the brain.
People who eat a vegetarian diet rich in nuts, vegetables and soy may have a lower risk of stroke than people who eat a diet that includes meat and fish, according to a new study.
Adolescents who are bullied about their weight or body shape may be more likely to use alcohol or marijuana than those who are not bullied, according to new research.
R esearchers argue that obesity should be considered premature aging. They look at how obesity predisposes people to acquiring the kinds of potentially life-altering or life-threatening diseases normally seen in older individuals: compromised genomes, weakened immune systems, decreased cognition, increased chances of developing type 2 diabetes, Alzheimer's disease, cardiovascular disease, cancer and other illnesses.
Different types of food are linked to risks of different types of stroke, according to the largest study to investigate this. The study of more than 418,000 people in nine European countries investigated ischaemic stroke and haemorrhagic stroke separately.
Several processes in the roundworm C. elegans boost the stress response in cells, incidentally making worms resistant to a high-fat diet and extending their lifespan. Researchers have found another: cells called glia that release a hormone that boosts the unfolded protein response in the endoplasmic reticulum of the worm's cells, effectively doubling lifespan. This could lead to interventions to tune up peripheral cells, such as muscle cells, and prevent age-related deterioration in humans.
Researchers discover a potential new way in which diet influences aging-related diseases.
A healthy diet is essential to living well, but should we change what we eat as we age? Researchers have found strong evidence of the link between food groups and memory loss and its comorbidities. Her findings point to a need for age-specific dietary guidelines as the links may vary with age -- people aged 80+ with a low consumption of cereals are at highest risk of memory loss and comorbid heart disease.
Eating a Mediterranean diet for a year boosts the types of gut bacteria linked to 'healthy' ageing, while reducing those associated with harmful inflammation in older people, indicates a five-country study.
Social media users are more likely to eat fruit and veg -- or snack on junk food -- if they think their friends do the same, a new study has found.
When high self-control individuals touch food directly with their hands (vs. indirectly with a utensil), they not only experience it as tastier and more satisfying, but they eat more of it. The work may not only offer a way to increase the appeal of food but also offers retailers a simple way to make the eating experience more enjoyable for consumers sampling food.
Eating walnuts may help slow cognitive decline in at-risk groups of the elderly population, according to a study conducted by researchers in California and Spain.
New research reveals the impact of smell loss. As many as one in 20 people live without smell. But until now there has been little research into the range of emotional and practical impacts it causes. The new study finds that almost every aspect of life is disrupted - from everyday concerns about personal hygiene to a loss of sexual intimacy and the break-down of personal relationships.
A new study has definitively shown that regular exposure to THC, the main psychoactive ingredient in cannabis, during pregnancy has significant impact on placental and fetal development.
New research shows soybean oil not only leads to obesity and diabetes, but could also affect neurological conditions like autism, Alzheimer's disease, anxiety, and depression.
When newborn babies with low birth weight are held close to their mother's bodies throughout the day, their chance of survival increases substantially.
A new study finds that the pleasure center of the brain and the brain's biological clock are linked, and that high-calorie foods -- which bring pleasure -- disrupt normal feeding schedules, resulting in overconsumption.
A mother's obesity in pregnancy can affect her child's development years down the road, according to researchers who found lagging motor skills in preschoolers and lower IQ in middle childhood for boys whose mothers were severely overweight while pregnant. At age 7, the boys whose mothers were overweight or obese in pregnancy had scores 5 or more points lower on full-scale IQ tests. No effect was found in the girls.
A drug that once helped obese adults lose weight, withdrawn from the market due to heart risks, may be safe and effective for children with a seizure disorder called Dravet syndrome, say researchers. The drug fenfluramine was developed for pediatric use and found to decrease the number of seizures by more than half for many Dravet syndrome patients.
A new study from a team of clinical psychologists suggests eating added sugars -- common in so many holiday foods -- can trigger metabolic, inflammatory and neurobiological processes tied to depressive illness.
Women who consumed a diet high in added sugars and refined carbohydrates had a greater risk of developing insomnia, a new study has found.
A team of researchers has now identified a specific circuit in the brain that alters food impulsivity.
A previously unknown mechanism that suppresses satiety signals from the small intestine is the main finding of a new study. This may explain, first, satiety disorders in obesity and diabetes and, second, the prompt health effects of gastric bypass, a form of bariatric surgery.
A ketone-supplemented diet may protect neurons from death during the progression of Alzheimer's disease, according to research in mice.
Simulations predict that behavioral interventions such as imposing strict no-food restrictions after meals can be as effective as strong anorectic drugs in reducing food intake in rodents, according to a study.
Researchers using MRI have found signs of damage that may be related to inflammation in the brains of obese adolescents, according to a new study.
A new study finds that cognitive impairment begins in the earliest stages of age-related hearing loss -- when hearing is still considered normal.
A new study investigates differences in how men and women perceive their own health. The study finds that confidence in maintaining good health habits can be influenced by gender.
For the first time, a study shows how glucocorticoid hormones, such as cortisol, control sugar and fat levels differently during day and night, feeding and fasting, rest and activity, over the course of 24 hours.
A newly released study found that rats of advanced age, treated with the drug rapamycin, maintained superior blood flow to the brain compared to younger, untreated rats. The treated rats also exhibited improved memory.
Adolescents and young adults with anorexia nervosa whose weight is in the healthy, overweight or obese ranges face similar cardiovascular and other health complications as their counterparts with low body mass index (BMI), according to a new study.
